Flap Loss Research Articles

One versus two vein anastomoses in breast reconstruction with a profunda artery perforator flap-does it make a difference.

The profunda artery perforator (PAP) flap has gained popularity as a reliable alternative in breast reconstruction. Extensive research has focused on its vascular supply, dissection techniques, and broader applications beyond breast reconstruction. This study aims to investigate the correlation between the number of veins anastomosed for the PAP flap and postoperative complications. A retrospective study was conducted to evaluate the outcomes of breast reconstructions with PAP flaps at our institution between 2018 and 2022. A total of 103 PAP flaps in 88 patients were included. Statistical analysis was performed to compare outcomes between flaps with one vein anastomosis and those with two vein anastomoses. Patient characteristics, intra and postoperative parameters were analysed. One vein anastomosis was used in 36 flaps (35.0%), whereas two vein anastomoses were used in 67 flaps (65.0%). No significant differences were found in patient characteristics between the one vein and two vein groups. The comparison of ischemia times between flaps with one versus two veins revealed no statistically significant difference, with mean ischemia times of 56.2 ± 36.8 min and 58.7 ± 33.0 min, respectively. Regarding outcomes, there were no statistically significant differences in secondary lipofilling, revision of vein anastomosis, or total flap loss between the two groups. Fat necrosis was observed in 5 (13.9%) one vein flaps and 5 (7.5%) two vein flaps, indicating no statistically significant difference between the two groups (p = .313). In the one vein group, the most frequently employed coupler ring had a diameter of 2.5 mm. In the two vein group, the most prevalent combination consisted of a 2.0 mm diameter with a 2.5 mm diameter. Based on our study results, both one vein anastomosis and two vein anastomoses are viable options for breast reconstruction with PAP flap. The utilization of either one or two veins did not significantly affect ischemia time or flap loss. Fat necrosis exhibited a higher incidence in the single-vein group; however, this difference was also not statistically significant. These findings underscore the effectiveness of both approaches, providing surgeons with flexibility in tailoring their surgical techniques based on patient-specific considerations and anatomical factors.

Posterior Positioning of Levator Veli Palatini with Intact Nasal Layer and Side-by-Side Bilateral Buccinator Flaps: Modified Approach for Palatal Lengthening.

To introduce a modified surgical method using bilateral buccinator flaps with posterior positioning of levator veli palatini muscles to treat velopharyngeal insufficiency. Cross-sectional clinical study. Non-syndromic patients with velopharyngeal insufficiency. We performed a modified surgical method using posterior positioning of levator veli palatini muscles and side-by-side bilateral buccinator flaps. Patients' characteristics, severity of hypernasality, palatal lengthening size, and operative complications were recorded and described. The severity of hypernasality was determined by a speech therapist before and after the operation. A total of 26 non-syndromic patients, with a median age of 8.5 years, were enrolled. All patients presented with severe hypernasality. Following the operation and during the follow-up period, 12 patients showed a complete resolution of hypernasality, while 9, 3, and 2 patients exhibited mild, moderate, and severe hypernasality, respectively. In addition, the mean palatal lengthening was measured to be 25.3 ± 3.5 mm. Overall, three patients experienced partial flap loss in one flap, which was successfully repaired with a secondary intention without the development of a fistula. In five cases, complete closure of the donor sites couldn't be achieved and thus were treated with secondary intention. Additionally, postoperative food restrictions were observed in seven cases but were resolved within one month. No other complications were noted in the remaining patients. This modified palatal lengthening technique results in a significant lengthening of the palate while maintaining favorable speech outcomes. Future randomized clinical trials are warranted to validate our findings.

Coverage of complex pararectal pelvic defects: role of the free myocutaneous musculus vastus lateralis flap

In the event of an advanced rectal carcinoma, an evisceration with rectal amputation may become necessary. The resulting defects, due to their extent, depth, or local tissue damage from previous surgeries and radiation, can in many cases only be closed through free microvascular tissue transfer. In this case series, we demonstrate the successful combination of a musculocutaneous musculus vastus lateralis flap (MVL) with a direct connection to the superior gluteal artery. Over a 47-month period, we retrospectively examined 11 cases of patients with dorsal pelvic defects after evisceration and rectal amputation that could not be closed using local or regional means. In cases of extensive defects with deep pararectal wound cavities, all these patients underwent defect coverage through a free myocutaneous MVL flap with a direct vascular anastomosis to the superior gluteal vessels. The mean defect size was 290.0 cm² (SD: 131.2; range: 200-600 cm²). The mean defect depth was 10.5 cm, necessitating MVL flap reconstruction with an average size of 336.3 cm². Three operative revisions were required due to postoperative bleeding. There were no arterial or venous thromboses, and no flap loss occurred. Only one necrosis of a distal flap tip was observed, which could be corrected secondarily by direct suturing. The case-mix evaluation yielded an average value of 24.251 (SD: 21.699; range: 7.036-65.748) points, emphasizing the complexity of the cases. Our results indicate that a free microvascular MVL flap is a viable therapeutic option for pararectal defects that cannot be closed by local or regional methods. The superior gluteal artery proves to be a safe and sufficient vascular connection. In combination, even extensive defects can be successfully closed.

Lip prosthesis as a palliative care modality for a head and neck cancer patient—A case report

The present case report describes the prosthetic management following partial loss of free-fibular osteocutaneous flap in an irradiated patient diagnosed with recurrent head and neck cancer. The patient presented with constant drooling of oral fluids due to an anatomically deficient lower lip. Salvage reconstructive surgery was not considered feasible due to past history of recurrence, multiple surgeries and radiotherapy, and financial constraints. An adhesive-retained interim silicone prosthesis was fabricated to alleviate the functional and psychosocial morbidity. The prosthesis served to restore the oro-facial seal to prevent constant drooling of oral fluids. It also aided in providing an excellent aesthetic solution to palliate the psychological suffering experienced by the patient due to lost facial contours.

The role of free flap reconstruction after resection of extremity and trunk soft tissue sarcomas. Results of two referral centers in Argentina

IntroductionFor patients affected by extremity or trunk soft-tissue sarcomas (STS) large resections might be needed to achieve negative margins. This is a common scenario especially in locally advanced or recurrent tumors often within a pre-irradiated field. The objective of this study was to evaluate the results of free-flap reconstructions (FFR) after sarcoma surgery. ObjectiveThe endpoints were surgical results, quality of surgical margins and oncological outcome. MethodsRetrospective analysis of patients with extremity and trunk STS with free-flap reconstruction between 2008 and 2022. Demographic and tumor data, perioperative treatment, margin status, morbidity and evolution were evaluated. ResultsOf 467 patients, 25 (5.35%) required 26 free-flap reconstructions. Surgery was performed on an irradiated field in 8 (32%) patients. Reconstructions were mostly needed for distal lower extremity resections and the most common type of flap used was antero-lateral tight (ALT) flap. No R2 resections were performed. R0 and R1 resections were achieved in 22 (84.6%) and 4 (15.4%), respectively. All R1 resections were preplanned positive along a preserved critical structure. Surgical morbidity rate was 26% (7/26) and the re-operation rate was 15% (4/26) with 7.7% flap losses (2/26). At a median follow-up of 38 months, 7 (28%) patients presented local recurrences. ConclusionIn a referral sarcoma center, having a multidisciplinary surgical team capable of complex resections and reconstructions is of utmost importance for a correct and integral surgical planning. This allows optimal oncologic resections with acceptable morbidity.

Simultaneous Co-surgeon Deep Inferior Epigastric Perforator (DIEP) Flap Breast Reconstructions: Feasibility and Clinical Outcomes.

A co-surgeon model is known to be favorable in microvascular breast reconstruction, but simultaneous co-surgeon deep inferior epigastric perforator (DIEP) flap cases have not been well-studied. The authors hypothesize that performing two simultaneous co-surgeon bilateral DIEP flap reconstructions results in non-inferior clinical outcomes and may improve patient access to care. A single-institution, retrospective cohort study was performed utilizing record review to identify all cases of co-surgeon free-flap breast reconstructions over a 38-month period. Patients who underwent simultaneous bilateral DIEP flap breast reconstructions with the same two co-surgeons were identified. The control group consisted of subjects who underwent non-simultaneous reconstruction by the same co-surgeons within the same, preceding, or following month of those in the study group. Primary outcome variables were 90-day postoperative complications, while secondary outcomes were operating time, ischemia time, and length of stay. Descriptive statistics, univariate and multivariable regression analyses were performed. Overall, 137 subjects were identified and 64 met the inclusion criteria (n=28 study, n=36 control). There were no statistically significant differences between groups in body mass index, radiation, trainee experience, flap perforator number, immediate/delayed reconstruction, or length of stay. There were also no statistically significant differences in complications, including flap loss, anastomosis revision, take-back to the operating room, or re-admission. Operative time was longer in the simultaneous DIEP group (540.5 vs. 443.5 min, p<0.01), but ischemia time was shorter in the simultaneous group (64.0 vs. 80.5min, p<0.01). A simultaneous co-surgeon approach to bilateral DIEP flap reconstruction may improve access to care and does not result in a higher complication rate compared with non-simultaneous bilateral DIEP flaps.

Social Determinants of Health and Patient-reported Outcomes Following Autologous Breast Reconstruction, Using Insurance as a Proxy.

Insurance type can serve as a surrogate marker for social determinants of health and can influence many aspects of the breast reconstruction experience. We aimed to examine the impact of insurance coverage on patients reported outcomes with the BREAST-Q (patient reported outcome measure for breast reconstruction patients, in patients receiving) in patients receiving deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. We retrospectively examined patients who received DIEP flaps at our institution from 2010 to 2019. Patients were divided into categories by insurance: commercial, Medicaid, or Medicare. Demographic factors, surgical factors, and complication data were recorded. Descriptive statistics, Fisher's exact, Kruskal-Wallis rank sum tests, and generalized estimating equations were performed to identify associations between insurance status and five domains of the BREAST-Q Reconstructive module. A total of 1,285 patients were included, of which 1,011 (78.7%) had commercial, 89 (6.9%) had Medicaid, and 185 (14.4%) had Medicare insurances. Total flap loss rates were significantly higher in the Medicare and Medicaid patients as compared to commercial patients; however, commercial patients had a higher rate of wound dehiscence as compared to Medicare patients. With all other factors controlled for, patients with Medicare had lower Physical Well-being of the Chest (PWBC) than patients with commercial insurance (β = - 3.1, 95% confidence interval (CI): -5.0, -1.2, p = 0.002). There were no significant associations between insurance classification and other domains of the BREAST-Q. Patients with government-issued insurance had lower success rates of autologous breast reconstruction. Further, patients with Medicare had lower PWBC than patients with commercial insurance regardless of other factors, while other BREAST-Q metrics did not differ. Further investigation as to the causes of such variation is warranted in larger, more diverse cohorts.

The intraoperative application of indocyanine green (ICG), in breast reconstructive surgery using a latissimus dorsi flap, as a preventive factor for tissue ischemia and postoperative complications

Introduction: Breast cancer is the most frequent cancer among women. Nowadays more and more women decide to undergo breast reconstruction, both using implants as well as autologous flaps. The most important factor in avoiding bad wound healing is the preservation of blood supply and good tissue perfusion. Latissimus dorsi flap is a commonly used method, mainly reserved for irradiated patients, delayed reconstruction, or salvage procedures. With damaged tissues, objectively assessing the conditions is much more difficult than in primary surgery.Aim: The aim of the study is to present the intraoperative application of ICG, in breast reconstructive surgery with a latissimus dorsi flap, as a preventive factor for tissue ischemia and postoperative complications. Materials and methods: A single-center retrospective review of the outcomes of 12 patients who underwent breast reconstruction using an LD flap, with an intraoperative assessment of flap blood supply using ICG. Patient characteristics, comorbidities, and smoking were taken into account. Results: In two cases, after an initial assessment of tissue perfusion, it was decided to resection the distal part of the flap with less blood supply. All reconstructions were successful and the wounds healed properly. None of the patients required reoperation, there were no postoperative complications or surgical site infections.Conclusion: The use of ICG in breast reconstruction with an LD flap is an important predictor of postoperative complications, especially flap necrosis and loss of reconstruction.

The Impact of Technical Innovations and Donor-Site Mesh Repair on Autologous Abdominal-Based Breast Reconstruction-A Retrospective Analysis.

Background: The aim of this study was to examine the potential benefit that may be achieved through the introduction of technical innovations and the incorporation of mesh for fascial donor site closure in uni- and bilateral autologous breast reconstruction with abdominal tissue. Methods: A retrospective single-center review of all breast reconstructions with a DIEP or MS-TRAM flap between January 2004 and December 2019 was performed. Donor and recipient site complications and operation times were evaluated before and after the implementation of coupler anastomoses, preoperative computed tomography angiography (CTA), indocyanine green (ICG) angiography, and the inclusion of mesh in donor site repair. Results: A total of 396 patients were included, accounting for 447 flaps. Operation time was significantly shorter in unilateral reconstructions after the implementation of CTA (p < 0.0001). ICG angiography significantly reduced the rates of partial flap loss (p = 0.02) and wound healing disorders (p = 0.02). For unilateral reconstructions, abdominal bulging or hernia was observed more often in MS1-TRAM flaps without synthetic mesh repair (p = 0.001), whereas conservatively treated seroma developed more frequently after mesh implantation (p = 0.03). Conclusions: Recent technological advancements developed over the past few decades have made a substantial impact on decreasing surgical duration and enhancing procedure safety.

Premastectomy Radiotherapy and Immediate Breast Reconstruction

Premastectomy radiotherapy (PreMRT) is a new treatment sequence to avoid the adverse effects of radiotherapy on the final breast reconstruction while achieving the benefits of immediate breast reconstruction (IMBR). To evaluate outcomes among patients who received PreMRT and regional nodal irradiation (RNI) followed by mastectomy and IMBR. This was a phase 2 single-center randomized clinical trial conducted between August 3, 2018, and August 2, 2022, evaluating the feasibility and safety of PreMRT and RNI (including internal mammary lymph nodes). Patients with cT0-T3, N0-N3b breast cancer and a recommendation for radiotherapy were eligible. This trial evaluated outcomes after PreMRT followed by mastectomy and IMBR. Patients were randomized to receive either hypofractionated (40.05 Gy/15 fractions) or conventionally fractionated (50 Gy/25 fractions) RNI. The primary outcome was reconstructive failure, defined as complete autologous flap loss. Demographic, treatment, and outcomes data were collected, and associations between multiple variables and outcomes were evaluated. Analysis was performed on an intent-to-treat basis. Fifty patients were enrolled. Among 49 evaluable patients, the median age was 48 years (range, 31-72 years), and 46 patients (94%) received neoadjuvant systemic therapy. Twenty-five patients received 50 Gy in 25 fractions to the breast and 45 Gy in 25 fractions to regional nodes, and 24 patients received 40.05 Gy in 15 fractions to the breast and 37.5 Gy in 15 fractions to regional nodes, including internal mammary lymph nodes. Forty-eight patients underwent mastectomy with IMBR, at a median of 23 days (IQR, 20-28.5 days) after radiotherapy. Forty-one patients had microvascular autologous flap reconstruction, 5 underwent latissimus dorsi pedicled flap reconstruction, and 2 had tissue expander placement. There were no complete autologous flap losses, and 1 patient underwent tissue expander explantation. Eight of 48 patients (17%) had mastectomy skin flap necrosis of the treated breast, of whom 1 underwent reoperation. During follow-up (median, 29.7 months [range, 10.1-65.2 months]), there were no locoregional recurrences or distant metastasis. This randomized clinical trial found PreMRT and RNI followed by mastectomy and microvascular autologous flap IMBR to be feasible and safe. Based on these results, a larger randomized clinical trial of hypofractionated vs conventionally fractionated PreMRT has been started (NCT05774678). ClinicalTrials.gov Identifier: NCT02912312.

Can Loupe magnification be a viable alternative to Operative Microscope magnification for vascular anastomosis in reconstructive surgery? A systematic review and meta-analysis

PurposeThe aim of this study is to compare the outcomes of vascular anastomosis using loupes magnification versus operative microscope magnification in reconstructive surgery. MethodsWe performed a systematic review of MEDLINE (via PubMed), Scopus and Cochrane Library database according to the PRISMA guidelines. Comparative studies between the two techniques and single arm studies reporting on loupes reconstruction were included. Random-effects model meta-analyses were performed. ResultsTwelve studies, reporting a total of 3908 of flaps, 3409 of which were performed under loupes magnification and 499 under the operative microscope magnification were selected for analysis. No statistically significant differences were observed regarding total flap loss and vascular complication between the two arms. In the Loupes group the rate of total flap loss was 2.65% (95% CI: 1.15–4.63) and the rate of vascular complications 4.49% (95% CI: 2.58–6.84). ConclusionLoupes magnification under circumstances can provide a safe and effective alternative to microvascular reconstruction in reconstructive surgery. With respect to flap failure and vascular complication rates, there appear to be no statistically significant differences between the anastomoses conducted under Loupes magnification and the standard operative microscope.

Analysis of Operation Duration in Thoracodorsal Artery Perforator Free-Flap Surgery of the Lower Extremities.

This retrospective study aimed to identify the factors that affect the duration of thoracodorsal artery perforator (TDAP) free-flap surgery and to offer strategies for optimizing the surgical procedure. We analyzed 80 TDAP flap surgeries performed by a single surgeon between January 2020 and December 2022, specifically focusing on free flaps used for lower-extremity defects with single-artery and single-vein anastomosis. The operation duration was defined as the time between the surgeon's initial incision and completion of reconstruction. Linear regression analyses were conducted to identify the factors affecting operation duration. The average operative duration was 149 minutes (range, 80-245 minutes). All flaps survived, although 8 patients experienced partial flap loss. The operative duration decreased with increasing patient age and when end-to-end arterial anastomosis was performed. However, the risk increased with larger flap sizes and in patients with end-stage renal disease. Our study identified several factors and methods that could accelerate TDAP free-flap procedures. These findings offer valuable insights for optimizing surgical processes and improving overall surgical outcomes. Although further research is needed to confirm and expand upon these findings, our study provides important guidance for surgeons in developing effective strategies for TDAP flap surgery.

Robot-assisted Microsurgery for Autologous Breast Reconstruction - Robotic Breast Reconstruction

With the introduction of novel surgical robots and surgical microscopes for the special needs of open microsurgery, the concept of robotic-assisted microsurgery is gaining popularity. While initial preclinical studies indicate a steep learning curve, favourable ergonomics and improved precision, albeit with an increased operating time, data on the clinical application of the new systems is still limited. This study describes our first clinical experience with robotic-assisted autologous breast reconstruction and outlines the opportunities and limitations of the approach. Our retrospective data analysis included a total of 28 patients who underwent unilateral robotic-assisted autologous breast reconstruction between July 2022 and August 2023. We applied a combined approach using the Symani Surgical System together with the RoboticScope. Descriptive evaluation of patient characteristics, surgical data and complications was performed. Average patient age was 54.3±11.1 years and average BMI was 26.5±3.5 kg/m2. Twenty-six patients received a DIEP flap and 2 patients received a PAP flap, the flaps being connected to the internal mammary artery in 22 cases, to a perforator of the internal mammary artery in 5 cases, and to a branch of the thoracodorsal artery in one case. The average incision-suture time was 267±89 min, with an average ischaemia time of 86±20 min and duration of the arterial anastomosis of 29±12 min. In two cases, immediate intraoperative anastomosis revision was performed, but no flap loss occurred. The results of this study demonstrate the safe feasibility of robot-assisted autologous breast reconstruction using a combination of Symani and RoboticScope. In the future, special attention should be paid to minimally invasive techniques of flap harvest and connecting vessel preparation.

Maxillofacial Microvascular Free-Flap Reconstructions in Pediatric and Young Adult Patients-Outcomes and Potential Factors Influencing Success Rate.

Background: Maxillofacial microvascular free-flap reconstructions are significant interventions in the management of congenital defects, traumatic injuries, malignancies, and iatrogenic complications in pediatric and young adult patients. Craniofacial disorders within this demographic can result in profound functional, cosmetic, and psychosocial impairments, highlighting the critical need for thorough investigation into factors that may influence procedural success and postoperative quality of life. This retrospective chart review aims to examine the outcomes and potential influencing factors, aiming to offer valuable insights into optimizing the effectiveness of these reconstructions and improving patient outcomes. Methods: A single head and neck surgical team performed all the included 136 procedures. Demographic and surgical patient data were recorded. Type of transfer performed in each recipient site and major complications were analyzed. Relevant influencing factors, such as age, gender, and etiology of defect were determined using the ANOVA test and χ2 test of independence. Results: The results indicate a 90% success rate. No significant relationship was found between the incidence of total flap loss and patient age, etiology, or graft source. The maxillary reconstructions showed a higher incidence of total flap loss compared to mandibular reconstructions (11 vs. 3 cases). Conclusions: Despite the high success rate, the findings underline the necessity for further research to validate these observations and enhance surgical methods for pediatric and young adult patients.

The introduction of microvascular free tissue transfer in primary burn reconstruction. Experience report of the national burn center in Chile

BackgroundSurgical debridement and split thickness graft is the most common treatment for acute burn patients that require surgery. However, there is a relevant minority that will require more complex reconstructive options. Microsurgery has evolved as a valuable tool in the acute setting allowing early closure of complex wounds in order to avoid infection, maintain function and even for limb salvage in one stage reconstruction. We present our experience in the management of severely acute burned patients with free flaps, flap survival rate and complications in Chile’s National Health service. MethodWe performed a retrospective analysis of all major burn patients admitted in our unit who received a microsurgical flap in the period between april 2019 and march 2023. Data was collected on patient sex, age, mechanism of injury, total burned surface area (TBSA), location of the defect, days to reconstruction, flaps used, operatory time, flap survival and complications. ResultsIn the study period we had 925 admissions. A total of 36 patients had 42 free flaps (5,1%). All but two patients were male (95 %), mean age 46 years (range 20–––76 years). Total body surface area burned averaged 14 % (range 1–64 %). The majority of injuries were caused by high voltage electricity (59 %) and fire (33 %). 59 % compromised lower limbs and 31 % upper limbs. In 81 % of the cases anterolateral thigh flaps were used. Mean time to reconstruction was 39 days(range 1–64 days), we had 9 complications (21 %) and only one flap was lost (2,9%). DiscussionThe introduction of free flaps in the burn reconstruction field was first described in sequelae management. In the acute phase it has also proven to be safe and feasible with a surgical indication of 1,5% to 2% of the admissions in different series. In our unit, 5,1% of our admissions required it, with a low flap loss rate. The increased confidence for its use in the acutely burned setting allowed us to achieve complex coverage while maintaining surgical risk and an internationally acceptable rate of losses and complications. Free flaps cpnstitute an active approach in the classical treatment of this pathology pushing the boundaries in the local environment.

The Impact of Marijuana Use on Postoperative Outcomes in Abdominal-based Free Flap Breast Reconstruction.

There is an increasing prevalence of marijuana use in the general population yet clinical studies on marijuana's effect on surgical outcomes remain limited. Marijuana's effect on wound healing, venous thromboembolism (VTE) due to endothelial inflammation, and bleeding due to inhibited platelet function have been cited based on animal models but have not been evaluated clinically in patients undergoing microsurgical reconstruction. Retrospective chart review was performed on all patients who underwent abdominal-based free flap breast reconstruction in a single institute from August 2018 to December 2022. Patient self-reported marijuana use, demographics, total narcotic use during hospitalization converted to oral morphine milligram equivalent (MME), and 90-day complications were collected and compared. A total of 162 patients were included and 13 patients (8.5%) had reported marijuana use on presurgical history. Marijuana users are more likely to be younger and report concurrent nicotine smoking. Marijuana users were also at a significantly elevated risk of developing symptomatic VTE (15 vs. 1%; odds ratio (OR) 13.4 [95% confidence interval (CI) 1.71-104.2]; p = 0.01) and marijuana use remained a significant risk factor with multivariate analysis. On postoperative 90-day complications, there was no increased risk of flap loss, reoperation, postoperative transfusion, or hematoma associated with marijuana use, and no significantly increased risk for overall donor or recipient site complications. Marijuana users required significantly more narcotics for pain control during hospitalization (100 ± 77 vs. 49 ± 45 MME; p = 0.0003), although they had similar lengths of stay, achievement of mobilization on post operative day (POD)1, and maximal pain scores. Marijuana use increases the risks of postoperative VTE and increased postoperative narcotic requirements in patients who underwent abdominal-based free flap breast reconstruction. Future prospective cohort study is required to further understand marijuana-associated risks in microsurgical procedures.

Head and neck reconstruction with the superficial circumflex iliac artery perforator (SCIP) free flap: Lessons learned after 73 cases.

Head and neck tissue defects after ablative surgery often require complex and composite reconstructions. The superficial circumflex iliac artery perforator (SCIP) flap is an extremely versatile perforator-based flap with minimal donor site morbidity, which may represent the optimal procedure in this setting. Over the last 5 years, we collected a large base of experience, including both simple and chimeric SCIP-based reconstruction, making this flap our first choice for head and neck reconstructions. Seventy-three patients undergoing ablative head and neck surgery for oncologic pathologies were treated by means of a SCIP flap reconstruction. Patients' mean age was 67 years old (range 37-89), 51 were males and 22 were females. Fifty-eight flaps were simple and 15 were chimeric reconstruction patterns. Indocyanine green perfusion imaging was performed in all cases. All the patients were successfully treated with no flap losses were encountered. Twelve patients encountered postoperative complications: in four cases revision surgery was required for venous congestion, while the remaining cases were managed conservatively (four wound dehiscence and three infections). No patients showed donor site complications. The mean follow-up period was 11 months (range 3-24). Our case series demonstrates the reliability and versatility of the SCIP flap for different kinds of head and neck reconstructions. The chimeric options combined with bone, double skin paddle, and muscle offer a broad variety of functional reconstructive solutions for complex head and neck surgeries. Intraoperative indocyanine green perfusion examination provides a valuable tool to assess and ascertain proper vascularization and post-anastomosis vessel patency in complex microvascular flap-based reconstructions.

An Interdisciplinary, Comprehensive Recovery Pathway Improves Microsurgical Breast Reconstruction Delivery.

Free-flap (autologous) breast reconstruction demonstrates superiority over alloplastic approaches but is offered infrequently. Enhanced recovery protocols can address postoperative challenges, but most literature is limited to inpatient interventions and outcomes. This study describes an adoptable, longitudinally comprehensive and multidisciplinary recovery pathway for autologous reconstruction which adds to the current guidelines. The authors aimed to allow perioperative outcomes comparable to alloplastic reconstructions. All autologous Comprehensive Recovery Pathway (CRP) subjects from a single surgeon were retrospectively included. A comparator group of equal size was randomly selected from institutional subpectoral and dual-plane tissue expander patients having Enhanced Recovery After Surgery guideline-directed care. All subjects in both cohorts received preoperative paravertebral regional blocks. Operative detail, inpatient recovery, longitudinal morphine equivalents (MEs) required, and complications were compared. Each cohort included 71 cases (99 breasts). Despite longer operations, intraoperative MEs were fewer in autologous cases ( P = 0.02). Morphine equivalents during inpatient stay were similar between cohorts, with both being discharged on median day 2. Multivariate regression demonstrated a 0.8-day increased stay for autologous subjects with additional contribution from bilateral cases, body mass index, and age ( P < 0.05). Autologous subjects were regularly discharged postoperative day 1 (17%) and postoperative day 2 (39%), with trend toward earlier discharge ( P < 0.01). Outpatient MEs were significantly fewer in autologous subjects, corresponding to a 30- to 150-mg oxycodone difference ( P < 0.01). Major complication occurred in 12.7% of autologous and 22.5% of alloplastic subjects ( P = 0.11). Flap loss occurred in 1 autologous subject versus 11 alloplastic failures ( P < 0.01). This study details partnership between the plastic surgery service, regional and acute pain anesthesia services, and dedicated nursing with longitudinal optimizations allowing perioperative outcomes improved over current literature. Patients in the CRP used fewer opioids from operation through follow-up with comparable length of stay and significantly fewer reconstructive failures than alloplastic subjects. The pathway may be quickly adopted into academic practice patterns and mitigates traditional barriers, allowing extension of autologous reconstruction offerings.

Nonmelanoma facial skin cancer: surgical planning for resection and reconstruction

Introduction The most effective treatment for nonmelanotic fascial skin cancer is surgical excision. Preoperative planning and a thorough grasp of reconstructive procedures, such as primary closure skin grafting, locoregional tissue flaps, remote tissue flaps, and free tissue transfer, are essential for the surgical therapy of these tumors. The choice of nonmelanoma skin cancer (NMSC) therapy is very specific to each patient and is influenced by the patient’s age, size, histologic subtype, and location of the disease. Treatment is to obliterate the lesion while maintaining normal tissue, function, and appearance. The ideas and methods of surgical excision and reconstruction of skin malignancies unique to the face were covered in this study. Patients and methods This study involved 98 patients of various ages and sexes. Of them, 89% had basal cell carcinoma and 11% had squamous cell carcinoma, both low-and high-risk tumors with varying sizes, locations, and histological subtypes. A safety margin of 3–5 mm is used for excision of low-risk malignancies and 5–10 mm for high-risk cancers. In 17 patients, skin grafts (split-thickness skin grafts and full-thickness skin grafts) are employed. 56 patients underwent local advancement, transposition, and rotational flaps; 15 patients underwent regional interpolation flaps; 6 patients sustained neck lymph node infiltration so they underwent cervical block dissection and distant pedicled flaps as latissimus dorsi muscle flaps; and 4 patients underwent cervical block dissection and free tissue transfer. Results Six patients experienced problems in the form of two partial graft and flap losses, two wound infections, and one scar retraction; however, with targeted care, they recovered well. Ninety-two percent of patients found the cosmetic outcomes satisfactory, and the functional outcome was good. Conclusion Wide excision and appropriate surgical reconstruction are ideal treatment modalities and may yield good aesthetic results or functional outcome, also the use of split-thickness skin grafts does not come as a first priority, where a lot of cases could have been treated with local flaps, as demonstrated in this consecutive series of treated patients. Treatment of NMSC on the face required a basic knowledge, presents a challenge to plastic surgeons, and is based on achieving the best oncological, functional, and cosmetic result. It is crucial to emphasize the need of patient education and appropriate tumor monitoring after NMSC therapy. A review of a big series of facial malignancy that may guide further studies cannot be understated.

Robot-assisted Microsurgery in Lower Extremity Reconstruction

In recent years, various robotic systems specifically designed for microsurgical tasks have been developed and approved. There is not much evidence for these systems to date. In our study, we examined the use of robot-assisted microsurgery in the reconstruction of the lower extremity. Data was prospectively collected between February and November 2023. The Symani robotic system was used in 42 robot-assisted microsurgical procedures on the lower extremity, and the results were evaluated and documented. The average age of the patients was 57±18 years. A total of 39 free flap reconstructions (95%), one lymphatic surgical procedure (3%) and two nerve transfers (5%) were performed. In total, 46 anastomoses and coaptations were carried out. This included six arterial end-to-end anastomoses (11%), seven arterial end-to-side anastomoses (13%), 36 venous end-to-end anastomoses (65%), two lymphovenous anastomoses (4%), and five epineural coaptations in the context of nerve transfers (9%). Arterial end-to-end anastomoses took an average of 26±12 minutes, and arterial end-to-side anastomoses took 42±21 minutes. The venous anastomoses took an average of 33±12 minutes. Epineural coaptations took an average of 24±13 minutes. In no procedure was there a need for a conversion to conventional hand suturing. There were two arterial thromboses (5%), one of which was successfully revised to save the flap. One total flap loss occurred, but there were no partial flap losses. Using the Symani robotic system for microsurgical reconstruction of the lower extremity, we were able to demonstrate results that are comparable to conventional microsurgery.
