Application of Three Different Types of Pedicled Latissimus Dorsi Flaps in Repairing Nearby Deep Soft Tissue Defects: Cosmetic Result and Shoulder Functionality Evaluation in One Center.

The latissimus dorsi (LD) flap has generally been considered a workhorse flap in clinics. However, the impairment of shoulder function and the dramatic appearance in the donor site are the major problems associated with traditional latissimus dorsi myocutaneous flap (LDMF). Here, we analyzed the reliability of three types of LD flaps in repairing deep soft tissue defects in the upper limbs, shoulder, back, and chest wall. From December 2016 to December 2020, 21 patients from our center underwent reconstruction of deep soft tissue defects using different types of LD flaps. The distribution of the thoracodorsal artery and the location of its branches were confirmed by imaging examination. Based on the defects, traditional LDMF, thoracodorsal artery perforator flap with capillary perforators (TAPcp), or low-skin-paddle pedicled LDMF was selected and specifically designed for each patient. The appearance satisfaction and shoulder functional of daily life recovery were evaluated. A total of 12 traditional LDMF, 4 TAPcp, and 5 low-skin-paddle pedicled LDMFs were used. All flaps survived well. The donor site was sutured directly with satisfactory appearance (n = 7) or repaired using skin grafts (n = 14). Compared to traditional LDMF, TAPcp and low-skin-paddle pedicled LDMF have faster shoulder function of daily life recovery. Based on the characteristics of defects, personalized design of different types of LD flaps is a reliable option to repair different defects.

Oncoplastic breast volume replacement with the use of lateral intercostal artery perforator flap

Breast cancer is very common, and there has been a lot of progress in terms of diagnosing and treating it. Surgical intervention, which is tailored to the patient's particular needs and numerous clinical concerns, is one of the management methods used. Some indicators that can be used are, for instance, the size and the stage. Smaller and earlier stage malignancies can be treated with a wide excision. However, getting a proper excision margin around the tumor and not removing too much tissue is problematic. Several studies have shown that when 20% of the breast volume is removed, there is a significant risk of deformity. Currently, oncoplastic surgery is the gold standard for breast reconstruction to minimize such a risk, and one of the techniques is volume replacement, which includes reconstruction of the breast with the transposition of tissue from elsewhere. Numerous volume replacement procedures were performed in the reported patients. The thoracodorsal artery perforator (TDAP) and lateral intercostal artery perforator (LICAP) flaps showed good outcomes in terms of cosmetic and oncological aspects, yet LICAP was found to be an excellent choice for the lateral breast defect and the aesthetic result was satisfactory. We present the case of a 19-year-old woman who had a borderline phyllodes tumor and 49-year-old woman with invasive breast cancer ductal carcinoma in situ (DCIS) that was treated with a wide excision and volume replacement with a LICAP. Following the success of the LICAP treatment, the defect appears symmetrical with the contralateral breast a few weeks following surgery. In conclusion, LICAP and TDAP flaps oncoplastic surgery offer advantages that should be considered to increase satisfactory of the patients after breast construction surgery in Indonesia.

Partial breast reconstruction of 30 cases with peri-mammary artery perforator flaps

BackgroundVolume replacement is one of the vital techniques of oncoplastic surgery (OPS) when applying breast-conserving surgery. The clinical application of peri-mammary artery perforator flaps for this indication is uneven in China. Here, we describe the results of our clinical experience with peri-mammary artery flaps for partial breast reconstruction.MethodsIn this study, 30 patients underwent partial breast resection for quadrant breast cancer followed by partial breast reconstruction with peri-mammary artery perforator flaps, which included the thoracodorsal artery perforator flap (TDAP), anterior intercostal artery perforator flap (AICAP), lateral intercostal artery perforator flap (LICAP), and lateral thoracic artery perforator flap (LTAP). All the patients’ operation plans were discussed comprehensively and were performed by sticking to every step. The satisfaction outcome was assessed with the extracted version of the BREAST-Q version 2.0, Breast Conserving Therapy Module Preoperative and Postoperative Scales both preoperatively and postoperatively.ResultsAccording to the study outcomes, the mean flap size was 5.3*4.2*2.8 cm (3.0–7.0*3.0–5.0*1.0–3.5 cm). The mean surgical time was 142 min (100–250 min). No partial flap failure was detected, and no severe complications were observed. Most patients were satisfied with the outcomes regarding the dressing, sexual life, and breast shape postoperation. Furthermore, the sensation of the surgical area, scar satisfaction, and recovery state gradually improved. Overall, LICAP and AICAP had higher scores when different flaps were compared.ConclusionsBased on this study, we found that peri-mammary artery flaps had significant value in breast-conserving surgery, especially in patients with small or medium-sized breasts. Perforators could be detected by vascular ultrasound before the operation. More than one perforator could be found most of the time. No severe complications occurred when performing a suitable plan, including discussing and recording the operation procedure; the focus of care, the choice for precise and proper perforators, and the mechanism for hiding the scars were all considered and recorded in a specific chart. Patients were satisfied with the reconstruction technique of peri-mammary artery perforator flaps after breast-conserving, and the satisfaction of AICAP and LICAP was higher. In general, this technique is suitable for partial breast reconstruction and has no negative impact on patient satisfaction.

Morbidity and quality of life following breast reconstruction by autologous latissimus dorsi flap, muscle sparing latissimus dorsi flap and thoracodorsal artery perforator flap

Background: Morbidity following autologous latissimus dorsi flap (ALD), muscle sparing latissimus dorsi flap (MSLD) and thoracodorsal artery perforator flap (TAP) is controversial. The purpose of this study was to measure morbity using Quick Dash at 1 month and 1 year following breast reconstruction with one of these three flaps. The second objective was the evaluation of quality of life using Breast-Q.

The Role of Computed Tomographic Angiography in Planning Thoraco-dorsal Artery Perforator (TDAP) Flap Reconstruction: A Systematic Review

The Role of Computed Tomographic Angiography in Planning Thoraco-dorsal Artery Perforator (TDAP) Flap Reconstruction: A Systematic Review

The Ultrasound Evolution of Lateral Thoracic Perforator Flaps Design and Harvest for Partial and Total Breast Reconstruction.

The lateral thoracic area is a known source for perforator flaps for partial breast reconstruction. In this paper, we report our experience in designing and harvesting lateral thoracic perforator flaps for partial and total breast reconstruction with the introduction of the "propuller" concept. Between September 2013 and August 2021, 95 flaps were performed for immediate, partial and total breast reconstruction. On a total of 95 flaps, 30 (19 thoracodorsal artery perforator(TDAP) flaps, 10 lateral intercostal artery perforator(LICAP) flaps and 1 lateral thoracic artery perforator(LTAP) flap) were harvested in the traditional fashion (control group) and 65 (57 LICAP, 2 LTAP and 6 TDAP flaps) according to the propeller concept (study group). All cases were preoperatively planned with Color-Coded Duplex Ultrasound. No flap losses were experienced in both groups. The mean operative time was 156 minutes (range 118-234) for the control group and 75 minutes (range 53-125) for the study group (p<0.0001). A significantly higher number of LICAP flaps were chosen in the study group compared to control group. None of the patients had donor site complications. Patients' and Surgeons' satisfaction was high to very high. The ultrasound preoperative planning led to the development of an easier and safer method of local perforator flap harvesting, that we named as propuller design. Its novelty lies in that perforator intraoperative selection and fully skeletonization are not needed and a more efficient flap movement (propeller plus advancement) which transfers more tissue into the new breast can be achieved safely, faster and easier.

Reconstruction of the Axillary Region after Excision of Hidradenitis Suppurativa: A Systematic Review.

Introduction Hidradenitis suppurativa (HS) is a chronic, debilitating, recurrent, auto-inflammatory disease of the pilosebaceous units of the skin. The axillary region is the most affected anatomical site and its reconstructive options include skin grafts, local random plasties, regional axial flaps, and regional perforator flaps. The main aim of this systematic review is to identify the best surgical technique for axillary reconstruction in the context of HS, in terms of efficacy and safety. Methods We adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) throughout the whole review protocol build-up. The literature search was performed using MEDLINE, Embase, and Cochrane library databases, updated to March 2021. Quality was assessed for each study, through the National Institutes of Health Quality Assessment Tool. Results A total of 23 studies were included in the final analysis. We reviewed a total of 394 axillary reconstructions in 313 patients affected by HS Hurley Stage II or III. Skin grafts were associated with the highest overall complication rate (37%), and highest rate of reconstruction failure (22%). Between thoraco-dorsal artery perforator flap, posterior arm flap, and parascapular flap, the latter showed fewer total complications, recurrences, and failures. Conclusion Regional axial flaps should be considered as the best surgical approach in the management of advanced HS. The parascapular flap emerges as the most effective and safest option for axillary reconstruction. Local random flaps might be considered only for selected minor excisions, due to the higher risk of recurrence. The use of skin grafts for axillary reconstruction is discouraged.

Diabetic foot resurfacing using microvascular tissue transfer from lateral thoracic region.

Diabetic foot ulcer is a major complication of diabetes mellitus and amputation is often needed. Since mortality rate after amputation is comparatively high, saving diabetic foot is required not only for preserving function and life quality, but also for decreasing mortality rate. This study was designed to analyse experience of limb salvage in patients with diabetic foot using free flaps from the lateral thoracic region over a 10-year period. Between 2009 and 2018, 297 cases of diabetic foot underwent surgical procedures. We analysed the 83 cases who underwent free flap from lateral thoracic region. Patient data were reviewed retrospectively. A total of 83 patients, 56 of them males, were included in this study. Age of patients ranged from 27 to 80years. Twenty patients underwent percutaneous transluminal angioplasty procedures. The latissimus dorsi muscle sparing technique was used in 7 cases. A thoracodorsal artery perforator flap was used in 68 cases. A thoracodorsal artery perforator chimaeric flap was performed in 8 cases. The flap survival rate was 98.8% and the limb salvage rate was 96.4%. The mean follow-up was 6.5years. During follow-up 14 patients suffered recurrence of foot ulcers. Ten-year experience of using flaps from the lateral thoracic region revealed superior outcomes in terms of flap survival and limb saving compared to those in a recent meta-analysis and other reports. Long vascular pedicle technique and the chimaeric technique might be the alternative methods for multiple or vascular insufficient diabetic foot defects.

Clinicopathologic features of epidermoid cysts in the upper and lower extremities, including a case of malignant transformation in the palmoplantar region

Purpose: Epidermoid cysts are common benign skin neoplasms derived from the pilosebaceous apparatus that usually develop in hair-bearing regions such as the head and neck. Epidermal cysts rarely occur in the extremities, especially in the palmoplantar region. Therefore, they can be easily misdiagnosed as warts or calluses. Here, we present our experience treating epidermal cysts in the extremities, including a very rare case of malignant transformation into squamous cell carcinoma. Methods: This retrospective study enrolled all patients who underwent excision of epidermoid cysts in the upper and lower extremities from March 2006 to April 2021.Results: Among 249 patients, there were 10 (seven male and three female patients) who had epidermal cysts in the extremities (4.0%). All four plantar cysts were located in weight-bearing areas. One palmar epidermal cyst occurred 33 years after the trauma. There was one case of a highly recurrent epidermal cyst on the heel that was eventually diagnosed as squamous cell carcinoma arising from the cyst lining on excisional biopsy. After wide excision with a margin of 2 cm, the resulting defect was reconstructed using a free thoracodorsal artery perforator flap. Conclusion: Epidermoid cysts in the extremities, especially the palmoplantar region, are rare. Detailed history taking, including underlying diseases and trauma history, is helpful for diagnosis. Complete excision is necessary to avoid relapse and to confirm the final diagnosis, especially in cases suspected of malignant transformation arising from epidermoid cysts.

Clinical application of microdissected thin thoracodorsal artery perforator flaps for repair of diabetic foot ulcers

To explore the effectiveness of microdissected thin thoracodorsal arterial perforator flap (TDAP) in repairing diabetic foot ulcers (DFUs). The clinical data of 11 patients with DFUs admitted between March 2020 and February 2021 were retrospectively analyzed, including 5 males and 6 females, aged from 22 to 67 years, with an average of 49.3 years. There were 10 cases of type 2 diabetes and 1 case of type 1 diabetes; the duration of diabetes ranged from 3 months to 25 years (median, 8 months). The duration of DFUs ranged from 6 days to 120 months (median, 1 month). There were 6 cases of grade 3 and 5 cases of grade 4 according to Wagner classification. The tissue necrosis and purulent secretions were found in all ulcer wounds, as well as different degrees of tendon and bone exposure; skin defects ranged from 5 cm×3 cm to 17 cm×6 cm. The DFUs were repaired by microdissected thin TDAP, including 6 cases of flaps (including 1 case of lobulated flap), ranging from 10.0 cm×4.5 cm to 26.0 cm×7.0 cm; 5 cases of chimeric perforator flaps, the range of the flap was 10.0 cm×4.5 cm to 16.0 cm×5.5 cm, and the range of the muscle flap was 6 cm×2 cm to 10 cm×3 cm. The donor site was sutured directly. The operation time ranged from 3.42 to 11.17 hours, with an average of 5.92 hours. All 11 flaps survived and no vascular crisis occurred; 1 patient had a sinus at the edge of the flap, and the surgical area healed well after dressing change. All 11 patients were followed up 6-12 months, with an average of 9 months. The flap texture was good, the recipient site was in good shape, and there was no swelling; the foot contour was good, the shoes were comfortable to wear, and the movement was good. The incision at the donor site healed by first intention, leaving only linear and concealed scar, without obvious depression deformity, and the shoulder joint function was good. On the premise of ensuring sufficient blood supply to the lower extremities and strengthening perioperative management, the microdissected thin TDAP to repair DFUs wounds can achieve better effectiveness and appearance; however, the prolonged operation time increases the probability of anesthesia and surgical risks in patients with DFUs.

610. NOVEL HYBRID TECHNIQUES FOR DELAYED RECONSTRUCTION OF THE CERVICAL PART OF A LEFT COLON INTERPOSITION: A CASE REPORT

Abstract Conduit necrosis following colon interposition for esophageal replacement is a devastating complication with a high morbidity and mortality rates. Survivors often face a challenging journey of complex reconstructive procedures. A multi-disciplinary approach is paramount to tailor the management according to the patient's anatomy, nutritional and psychological status, conduit alternatives and routes. This case report provides a series of novel reconstructive techniques, each of which could be helpful for esophageal surgeons facing such difficult situation. A 36 years old female, with a history of corrosive ingestion at the age of 5 years, who was subjected to series of regular dilatation since then, presented with a tight stricture not passing a wire. She underwent a subcutaneous isoperistaltic left colon interposition. The postoperative course was complicated with necrosis of the cervical part of the graft with infection of the subcutaneous tunnel. Resection was done with esophagostomy and colostomy in the neck. The patient survived the acute stage, feeding was established through the colostomy opening in the neck. Delayed reconstruction was planned 6 months later. The skin between the two openings in the neck was considered posterior wall of the conduit, and transaxillary pedicled thoracodorsal artery perforator flap (TDAP) was used to reconstruct the anterior wall (1,2). Partial flap loss occurred (3). Debridment and gastrostomy were done. The result was two gaps on both ends of the flap (3). The food regurgitated upwards from the gastrostomy. An antireflux stent was placed inside the flap to bridge the defects and allow oral intake (4). The TDAP-colon side was closed using a local flap from TDAP and skin graft (5,6). The esophageal side was closed primary and covered by a supraclavicular flap (7-12). Management of graft failure should focus on controlling sepsis and nutrition. Attempts should be made to preserve any surviving part of the conduit as long as it doesn’t add to sepsis. A combination of Myocutaneous flaps could be used to replace the cervical part of the conduit as TDAP and supraclavicular flaps. Stent could be used successfully to bridge a failure in a skin flap. Finally, a dedicated team is paramount for a successful outcome.

LICAP Versus TDAP for the Reconstruction of Partial Breast Defects.

Perforator flaps are the latest development in reconstructive surgery. Pedicled chest wall perforator flaps can be utilized in many cases of partial breast reconstruction. This research compares the outcome and technique of thoracodorsal artery perforator flap (TDAP) and the lateral intercostal artery perforator flap (LICAP) in the reconstruction of partial breast defects. Patient records were reviewed for the time period between 2011 and 2019 at the Breast Unit of the National Cancer Institute of Cairo University. Eighty three patients were accessible for the study. (46 cases of TDAP flap and 37 cases of LICAP flap). Relevant clinical data were extracted from patients' records. A special visit was organized for all 83 patients, where a digital photograph was taken in an antroposterior view. The photographs were later processed via BCCT.core software to obtain an objective cosmetic outcome assessment. Complication rates and cosmetic outcome were comparable for both techniques. TDAP flap proved to require more tedious dissection and preoperative Doppler mapping to localize perforator vessels. On the other hand, LICAP was technically easier with more consistent perforators. Pedicled chest wall perforator flaps constitute an excellent reconstructive option in partial breast defects. TDAP flap and LICAP are two reliable perforator flaps which can reconstruct outer breast defects with acceptable outcome.

Morbidité et qualité de vie après reconstruction mammaire par lambeau de grand dorsal autologue, à épargne musculaire et perforant

Morbidity following autologous latissimus dorsi flap (ALD), muscle sparing latissimus dorsi flap (MSLD) and thoracodorsal artery perforator flap (TAP) is controversial. The purpose of this study was to measure morbity using Quick Dash at 1month and 1year following breast reconstruction with one of these three flaps. The second objective was the evaluation of quality of life using Breast-Q. Thirty four consecutive patients who had undergone breast reconstruction were included in this monocentric and prospective study: 10patients in the ALD group, 12patients in the MSLD group and 12patients in the TAP group. At 1month and 1year following surgery, the variation of Quick Dash was 13,63and 2,38in the ALD group, 3,41and -1,13in the MSLD group and 5,69and 0in the TAP group. Satisfaction whith breasts, psychosocial, sexual and chest well-being were higher in the ALD group. Satisfaction with back was higher in the MSLD and TAP groups. Back and shoulder well-being was comparable regardless of the flap. Seroma occurrence was very rare in case of TAP, rare and not abundant in case of MSLD and frequent in case of ALD. This study appears to confirm that immediate morbidity is less important with MSLD or TAP than ALD. Hoewever at one year following surgery, morbity seems to be comparable with the 3flaps. Patients satisfaction seems to be higher with ALD except for the aspect of the back.

The Thoracodorsal Artery Perforator Flap: A Powerful Tool in Breast Reconstruction.

Perforator flap use in breast cancer reconstruction has evolved significantly in the last decade. The authors reviewed their experience and evaluated thoracodorsal artery perforator (TDAP) flap outcomes in breast reconstruction. A retrospective chart review was conducted of all women undergoing breast reconstruction between 2012 and 2018. Included were patients who underwent a mastectomy (unilateral or bilateral) with immediate reconstruction or requiring a revision reconstruction with a TDAP flap. Reconstruction for nonmalignant causes were excluded. Patient demographics, risk factors, indications, operative details, and complications were reviewed. Major (partial or total flap necrosis, hematoma, and wound breakdown requiring operative management) and minor (cellulitis, seroma, and minor wound breakdown managed with local wound care) complications were recorded. A total of 138 charts were reviewed for the years 2012 and 2018, and 126 patients met inclusion criteria. Mean patient age was 52.1 years. Mean patient body mass index was 29.1 kg/m 2 . A total of 174 TDAP flaps were performed. The success rate was 98.3 percent. There were three flap losses (all partial). Operable fat necrosis rate was 3 percent. Donor-site morbidity was low at a rate of 1.2 percent. There was no difference in complications between patients who had a history of radiation therapy and those who did not (16.7 and 18.6 percent, respectively; p = 0.829). This study is the largest series in the literature that highlights the utility of the TDAP flap in breast reconstruction. This flap is a powerful tool that should be considered in patients for whom other reconstructive options have been exhausted or unavailable. Therapeutic, IV.

Total breast reconstruction using thoracodorsal artery perforator (TDAP) flap with or without implants

Introduction: The thoracodorsal artery perforator (TDAP) flap has been increasingly used for breast reconstruction mainly due to reduced donor site morbidity compared to latissimus dorse (LD) flap. TDAP flap was mainly described for partial reconstruction of breast defects following breast conserving surgery. This study describes the use of the TDAP flap in total breast reconstruction with or without synthetic implants in two breast units. Methods: Between June 2017 and June of 2022, seven patients were included. Six patients from the Oncology Center, Egypt and one patient from Cambridge Breast Unit. Preoperative perforator mapping method was recorded. Patients’ demographic data, type of mastectomy and reconstruction and surgical outcome were recorded. Results: Five patients had total breast reconstruction without implants, whilst two patients had implant-enhanced TDAP reconstruction. The mean age of was 39 years (31-43), and the mean mean body mass index (BMI) was 28 kg/m2 (23-36). Median hospital stay was 3 days. All patients had immediate breast reconstruction following mastectomy without the need for contralateral symmetrization or corrective surgery. No seroma was reported. Only one patient had complete flap loss, while one patient who had minor wound infection.

Combined transfer by several perforator skin flaps to cover an extensive and multiplanar wound on the foot and ankle

BackgroundThis study aimed to assess the feasibility and effectiveness of using combined transfer by two or three large skin flaps to cover a single extensive and multiplanar wound on the foot and ankle to achieve full coverage of the wound and primary donor-site closure. Patients and methodsSeventeen patients with extensive wounds around their foot and ankle were treated. The flap could either be anterolateral femoral perforator (ALTP) flap, deep inferior epigastric artery perforator (DIEP) flap, or thoracodorsal artery perforator (TDAP) flap. According to the dimensions and shape of the wound and the availability of donor sites, we classified the reconstruction into three different types. Based on the type, the soft-tissue defect was divided into two or three parts to guide the corresponding perforator skin flaps to be harvested within the maximum width and length of the donor sites. ResultsAll 17 patients were successfully reconstructed, with a total of 35 flaps in 37 paddles. Vascular compromise occurred in one patient and was saved by venous thrombectomy. In total, four flaps experienced a partial loss and were treated either conservatively or by a skin graft. No ulceration due to abrasion occurred on any flap during the entire follow-up. All donor sites were directly closed and healed uneventfully, except for one needing coverage by a skin graft and another experiencing dehiscence and scar widening. ConclusionCombined transfer by several skin perforator flaps is a flexible reconstructive option for resurfacing extensive and multiplanar wounds on the foot and ankle. The benefit lies in a well-reconstructed contour, an anti-frictional property, a permission of a normal shoe wearing in the reconstructed foot, and meanwhile a primary closure on donor site.

Cubital fossa defect- our reconstructive experience with pedicle flaps

IntroductionCubital fossa wounds can be complicated by the non-availability of reliable, well-vascularized donor tissue. Closure with pliable and readily available donor tissue for cubital defect and early mobilization of the elbow joint is essential for better results. The authors did this study to see how best the results of cubital fossa defect cover can be achieved by pedicle flaps in a single stage without compromising the donor areas. Material and methodPatients having deep elbow wounds in which vital structures were lying exposed in the cubital region were included in this study. The patients were assessed for the availability of tissue for cover, reliability of flaps, flap pliability, the functional outcome of the elbow and donor site morbidity. ResultsA total of 17 cases of cubital region defects are presented wherein closure of the wound by means of primary closure was not possible. Out of these, eight were covered with Pedicled Thoracodorsal Artery Perforator (TDAP) flaps, five with Pedicled split Latissimus Dorsi Muscle (SLDM) flaps and four with reversed lateral arm flaps (RLA). Post-operatively all the flaps were healthy, patients attained a good range of elbow joint movements with no clinically evident morbidity of the donor site. ConclusionCubital fossa defect coverage needs dedicated planning to obtain a sturdy tissue for cover. In the presence of local tissue damage or scarring, we have looked elsewhere to bring pliable and well-vascularized tissue which is reliable. The flaps we used have allowed single-stage reconstruction and early mobilization of the elbow joint with good functional recovery.

Clinical effects of free transplantation of expanded thoracodorsal artery perforator flaps in reconstructing cervical cicatrix contracture deformity after burns

Objective: To explore the clinical effects of free transplantation of expanded thoracodorsal artery perforator flaps in reconstructing cervical cicatrix contracture deformity after burns. Methods: A retrospective observational study was conducted. From May 2018 to April 2021, 11 patients with cervical cicatrix contracture deformity after burns who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 3 males and 8 females, aged 5 to 46 years, with a course of cervical cicatrix contracture deformity of 5 months to 8 years. The degree of cervical cicatrix contracture deformity was degree Ⅰ in one patient, degree Ⅱ in nine patients, and degree Ⅲ in one patient. In the first stage, according to the sizes of neck scars, one rectangular skin and soft tissue expander (hereinafter referred to as expander) with rated capacity of 200 to 600 mL was placed in the back. The expansion time was 4 to 12 months with the total normal saline injection volume being 3.0 to 3.5 times of the rated capacity of expander. In the second stage, free expanded thoracodorsal artery perforator flaps with areas of 10 cm×7 cm to 24 cm×13 cm were cut out to repair the wounds with areas of 9 cm×6 cm to 23 cm×12 cm which was formed after cervical cicatectomy. The main trunk of thoracodorsal artery and vein were selected for end-to-end anastomosis with facial artery and vein, and the donor sites were directly closed. The survival of flaps and healing of flap donor sites were observed on the 14th day post surgery. The appearances and cicatrix contracture deformity of the flaps, recovery of cervical function, and scar hyperplasia of donor sites were followed up. Results: On the 14th day post surgery, the flaps of ten patients survived, while ecchymosis and epidermal necrosis occurred in the center of flap of one patient and healed 2 weeks after dressing change. On the 14th day post surgery, the flap donor sites of 11 patients all healed well. During the follow-up of 6-12 months post surgery, the flaps of ten patients were similar to the skin around the recipient site in texture and color, while the flap of one patient was slightly swollen. All of the 11 patients had good recovery of cervical function and no obvious scar hyperplasia nor contracture in the flaps or at the donor sites. Conclusions: Application of expanded thoracodorsal artery perforator flaps can restore the appearance and function of the neck, and cause little damage to the donor site in reconstructing the cervical cicatrix contracture deformity after burns, which is worthy of clinical reference and application.
