Evaluating Pedicled Pectoralis Major Myocutaneous Flap Reconstructions for Oral Malignancy and the Influence of Laterally Based Rotational Advancement Flap on Donor Site Integrity and Nipple Position in Male Patients.

Oral cancer poses a significant health burden, particularly in the male population of India. This study focuses on evaluating the outcomes of 48 pedicled Pectoralis major myocutaneous (PMMC) flap reconstructions in male patients with oral malignancy. Given the challenges associated with microvascular flap reconstructions, especially in advanced cancer cases, older patients, and resource-constrained settings, the PMMC flap still serves as a valuable alternative. The study introduces a novel approach by incorporating a laterally based rotational advancement flap (LBRA) to address donor site integrity and decrease the nipple-areolar complex (NAC) displacement. Traditionally, PMMC flap designs tend to cause inward shifting of the NAC during chest donor site closure, impacting the aesthetic outcome. Surgical techniques involved wide local resection, neck dissection, and PMMC flap reconstruction. The Flap design included a horizontal orientation with adjustments based on defect location. Additionally, a laterally based rotational flap from the chest aided in donor site closure. Results demonstrate the versatility and reliability of PMMC flap reconstructions, with no total flap necrosis or major complications observed in the 48 cases. The LBRA technique effectively mitigated NAC displacement. The study contributes to the existing literature by providing insights into the advantages of PMMC flap reconstructions and introducing a technique to optimize donor site closure and decrease the medial shifting of the nipple. The adaptability, reliable vascular supply, and simplified learning curve make the PMMC flap a preferred choice in resource-constrained settings with high patient demand. In conclusion, this research underscores the continued relevance and effectiveness of the PMMC flap in head and neck reconstruction, offering satisfactory cosmetic and functional results. The introduction of the LBRA technique adds a nuanced dimension to improve outcomes, particularly in male patients with oral malignancy.

The harvestion and application experience of free multi-lobed anterior thigh flap

Objective: To introduce the technique and clinical application of free lobed anteromedial thigh perforator pedicle flap. Methods: From September 2015 to September 2021, 72 patients with perforating buccal and oral cancer defects were treated at the Oncology Plastic Surgery Department of Hunan Cancer Hospital. There were 61 males and 11 females, with an average age of 36.7 years (31-56 years). According to Union for International Cancer Control (UICC) TNM staging, there were 20 cases of T3N1M0, 13 cases of T3N2M0, 24 cases of T4N0M0, and 15 cases of T4N1M0. All defects were planned to be repaired with free lobed anteromedial perforator flaps. When there was only one set of vascular pedicle, the perforating vascular pedicle artery was anastomosed with the superior thyroid artery, and the accompanying vein was anastomosed with the superior thyroid vein by end-to-end. Results: The areas of soft tissue defects after radical resection of oral and buccal cancers in 72 patients were between 5.0 cm × 4.0 cm and 11.0 cm×7.0 cm; the areas of the first anterior femoral skin islands were between 5.0 cm × 4.0 cm and 13.0 cm×7.0 cm; the areas of the second anterior femoral skin islands were between 5.0 cm × 3.0 cm and 10.0 cm × 7.0 cm; and all flap donor sites were directly closed. In 35 cases, the vascular pedicle was accompanied by a lateral femoral muscle flap for filling the gap defect at the base of the mouth. The average length of the vascular pedicles of the flaps was 7.2 cm (range: 6.8-8.2 cm). The average diameter of the vascular pedicle arteries was 1.6 mm (range: 1.4-2.2 mm). The blood flow reconstruction of flap was completed by anastomosing one accompanying vein. The average diameter of the accompanying veins was 2.1 mm (range: 1.6-2.8 mm). Postoperative hematoma occurred in 3 patients, with one having vascular crisis. After emergency exploration, 2 of them were successfully saved, and the other one had complete necrosis of skin flap, which was repaired by pedicled pectoralis major skin flap transplantation. With following up of 12-38 months, the appearances of the flaps were satisfactory without significant swelling. The mouth opening and language function were satisfactory in all cases, and only linear scars were left in the donor sites, with no significant impact on thigh functions. Five patients with local recurrence of tumor were treated with second radical resection and repair with pedicled pectoralis major myocutaneous flap. Six patients developed cervical lymph node metastasis (4 on the same side and 2 on the opposite side) and underwent neck dissection again. Conclusion: The anatomical basis of the branches of the anteromedial femoral perforating branches in the anterolateral region of the thigh can be helpful to prepare the anterolateral femoral lobed flap, which is suitable for repairing the perforating defects after the radical operation of oral and buccal cancers.

Technique and clinical application of free lobed anteromedial thigh perforator flap

To introduce the technique and clinical application of free lobed anteromedial thigh perforator flap. Between October 2017 and December 2021, 65 patients with buccal and oral cancer penetrating defects were planned to treat with free lobed anterolateral thigh flap transplantation, of which 15 cases were found that the sole anterolateral thigh perforator was actually a branch of the anteromedial thigh perforator, and then the free lobed anteromedial thigh perforator flap was harvested for repair. There were 12 males and 3 females with an average age of 34.6 years (range, 29-55 years). According to Union for International Cancer Control (UICC) TNM staging, there were 7 cases of T 4N 0M 0, 4 cases of T 4N 1M 0, 2 cases of T 3N 1M 0, and 2 cases of T 3N 2M 0. The disease duration was 1-10 months (mean, 6.3 months), and the area of secondary soft tissue defect left after radical resection of buccal and oral cancer was from 5 cm×4 cm to 10 cm×6 cm. The anterolateral thigh skin flap ranged from 5 cm×4 cm to 13 cm×6 cm, and the anteromedial thigh skin flap ranged from 5 cm×3 cm to 10 cm×6 cm. The free trilobed anteromedial thigh flap was prepared according to the actual branches of the main trunk of the anteromedial thigh perforator in 4 cases, and the vastus medialis muscle flap was used to fill the cavity defect of the floor of mouth in 7 cases. Among the 15 patients, the vessel pedicles of the anteromedial thigh perforators were derived from the main femoral artery and vein in 8 cases, from the main descending branch of the lateral femoral circumflex artery in 4 cases, and from the main lateral femoral circumflex artery in 3 cases. Hematoma occurred in 2 cases after operation, which was successfully saved after emergency exploration. No vascular crisis occurred, and partial necrosis of anterolateral femoral skin island occurred in 1 case, which was healed with debridement. The remaining flaps survived successfully, and the wounds and donor site incisions healed by first intention. All the patients were followed up 12-36 months (mean, 14.6 months). The appearance of the flap was satisfactory, and no obvious swelling was found; the mouth opening and language function were satisfactory; only linear scar was left in the donor area, and the thigh function was not significantly affected. Local recurrence occurred in 3 cases, and the defect after tumor resection was repaired with pedicled pectoralis major myocutaneous flap. Four patients with neck lymph node metastasis, including ipsilateral side in 3 patients and contralateral side in the other 1 patient, all underwent neck lymph node dissection again. The 3-year survival rate was 86.7% (13/15). The anteromedial thigh perforator vessels distributed in the anterolateral region of the thigh can be used to prepare the anterolateral thigh split lobed flap to repair the buccal and oral cancer penetrating defects.

Head and Neck Reconstruction With 2-Stage External Pectoralis Major Myocutaneous Flap Transfer.

In head and neck surgery cases where skin is severely scarred or adhered to surrounding tissue, reconstruction can be difficult to perform using microsurgical tissue or conventional pedicled pectoralis major myocutaneous flap (PMMF) transfer given the risks, which include damage to major vessels when manipulating scarred skin. For such cases, we perform a 2-stage external PMMF transfer, whereby the PMMF is directly sutured to the defect over the neck skin (without manipulation the hardened skin), and the flap division is then performed secondarily. A total of 30 patients who had histories of radiotherapy (60-70 Gy) and prior neck dissection received the 2-stage external PMMF transfer procedure. Indications for the flaps included pharyngeal fistula closure in 12 patients, reconstruction for mandibular necrosis after radiotherapy in 8 patients, salvage surgery for partial or total necrosis of the free flap in 4 patients, and simultaneous reconstruction after tumor excision in 6 patients. Two patients underwent a second external PMMF transfer from the contralateral side because of postoperative complications, yielding a total of 32 flap transfers. Twenty-nine flaps showed complete flap survival, whereas 3 had partial necrosis. Other complications, despite complete flap survival, included large fistulas requiring additional surgery for fistula closure (1 patient) and small fistulas that were closed without requiring reoperation (7 patients). External PMMF transfer offers a safe, simple, and effective option in cases where free flap surgery is considered difficult or the risks associated with neck manipulation are high.

Assessment of quality of life after soft tissue resection of head and neck carcinoma and reconstruction with double-paddle peroneal artery perforator free flap

We aimed to assess the quality of life for head and neck carcinoma (HNC) patients who underwent soft tissue resection and reconstruction with double-paddle peroneal artery perforator (DPAP) free flap. The quality of life was assessed by means of the University of Washington quality of life (UW-QOL) and the 14-item Oral Health Impact Profile (OHIP-14) questionnaires at 12 months postoperatively. Data from 57 patients were retrospectively analysed. Out of these, 51 patients were at TNM stage III or IV. Finally, 48 patients finished and returned the two questionnaires. In the UW-QOL questionnaire, the mean (SD) higher scores were pain 76.5 (6.4), shoulder 74.3 (9.6), and activity 71.6 (6.1), whereas the lower scores were chewing 49.7 (5.2), taste 51.1 (7.7), and saliva (56.7 (7.4). In the OHIP-14 questionnaire, the higher-scoring domains were psychological discomfort (69.3 (9.6) and psychological disability 65.2 (5.8), whereas the lower-scoring domains were handicap 28.7 (4.3) and physical pain 30.4 (8.1). The DPAP free flap significantly improved appearance, activity, shoulder, mood, psychological discomfort, and handicap compared with pedicled pectoralis major myocutaneous flap reconstruction. In conclusion, DPAP free flap for reconstruction of tissue defects after soft tissue resection of HNC significantly improved the patients' QOL compared to pedicled pectoralis major myocutaneous flap reconstruction.

An Uncommon Presentation of Constriction Band Syndrome: A Case Report and Review of Literature

One of the rarer manifestations of constriction band syndrome (CBS) is peripheral nerve palsy. We report a 6-year-old child presenting with motor deficits of the median, ulnar and radial nerves and atrophy of the biceps and brachialis atrophy due to CBS. We were unable to find any similar reports in the literature. He had a constriction ring at the upper arm that had undergone multiple z-plasty by another surgeon. On examination, he had medical research council (MRC) grade 1 elbow flexion, weak flexion of fingers and absent extension of fingers and wrist. We used a pedicled pectoralis major myocutaneous flap to restore elbow flexion and the patient achieved M4 flexion of the elbow. Level of Evidence: Level V (Therapeutic).

International assessment of interobserver reproducibility of flap delineation in head and neck carcinoma

Background: Several reports have suggested that radiotherapy after reconstructive surgery for head and neck cancer (HNC), could have deleterious effects on the flaps with respect to functional outcomes. To predict and prevent toxicities, flap delineation should be accurate and reproducible. The objective of the present study was to evaluate the interobserver variability of frequent types of flaps used in HNC, based on the recent GORTEC atlas. Materials and methods: Each member of an international working group (WG) consisting of 14 experts delineated the flaps on a CT set from six patients. Each patient had one of the five most commonly used flaps in HNC: a regional pedicled pectoralis major myocutaneous flap, a local pedicled rotational soft tissue facial artery musculo-mucosal (FAMM) (2 patients), a fasciocutaneous radial forearm free flap, a soft tissue anterolateral thigh (ALT) free flap, or a fibular free flap. The WG’s contours were compared to a reference contour, validated by a surgeon and a radiologist specializing in HNC. Contours were considered as reproducible if the median Dice Similarity Coefficient (DSC) was > 0.7. Results: The median volumes of the six flaps delineated by the WG were close to the reference contour value, with approximately 50 cc for the pectoral, fibula, and ALT flaps, 20 cc for the radial forearm, and up to 10 cc for the FAMM. The volumetric ratio was thus close to the optimal value of 100% for all flaps. The median DSC obtained by the WG compared to the reference for the pectoralis flap, the FAMM, the radial forearm flap, ALT flap, and the fibular flap were 0.82, 0.40, 0.76, 0.81, and 0.76, respectively. Conclusions: This study showed that the delineation of four main flaps used for HNC was reproducible. The delineation of the FAMM, however, requires close cooperation between radiologist, surgeon and radiation oncologist because of the poor visibility of this flap on CT and its small size.

Application of free peroneal artery chimeric perforator flap in repairing the defect after advanced local lesions resection in parotid gland carcinoma

To investigate the effectiveness of free peroneal artery chimeric perforator flap in repairing the defect after advanced local lesions resection in parotid gland carcinoma (PGC). Between June 2010 and June 2020, 32 patients with advanced local lesions of PGC were treated with extended radical resection. After that, 17 patients were repaired with the free peroneal artery chimeric perforator flaps (trial group) and another 15 patients were repaired with the pedicled pectoralis major myocutaneous flaps (control group). There was no significant difference in gender, age, disease type, histopathological classification, clinical stage, and pathological stage between groups ( P>0.05). The size of skin flap in trial group ranged from 7 cm×6 cm to 12 cm×8 cm and the size of soleus muscle flap ranged from 5 cm×3 cm to 6 cm×4 cm. The donor sites were repaired with skin grafting. The size of the pedicled pectoralis major myocutaneous flaps in control group ranged from 9 cm×6 cm to 14 cm×7 cm. The donor sites were sutured directly. The operation time, survival rate of flap, and postoperative survival of patients were recorded and compared between groups. At 1 year after operation, the University of Washington quality of life (UW-QOL) questionnaire was used to evaluate the quality of life of patients in the two groups, including appearance, shoulder movement, sociability, masticatory function, speech function, and mood. The operations completed successfully. The operation time was (6.19±0.72) hours in trial group and (6.41±0.71) hours in control group, showing no significant difference between groups ( t=-0.863, P=0.395). The survival rate of flap in trial group was 94.1% (16/17); and 1 patient suffered from vascular crisis after operation and was replaced with the pedicled pectoralis major myocutaneous flap. The survival rate of flap in control group was 100%. All grafts survived and the incisions healed by first intention in the two groups. All patients were followed up. The follow-up time was 6-60 months (median, 60 months) in trial group and 7-60 months (median, 60 months) in control group. Cumulative survival rates of patients at 1, 3, and 5 years after operation were 94.1%, 64.7%, and 58.8% in trial group, respectively; 86.7%, 66.7%, and 53.3% in control group, respectively. There was no significant difference in the cumulative survival rate between groups ( χ 2=0.090, P=0.762). According to the UW-QOL questionnaire at 1 year after operation, the scores of appearance, shoulder movement, sociability, and mood in trial group were significantly higher than those in control group ( P<0.05); and there was no significant difference in masticatory function and speech function scores between groups ( P>0.05). The peroneal artery perforator has an invariable anatomical relationship. Each perforator emits the muscular branch that nourishes the soleus muscle. Therefore, personalized free peroneal artery chimeric perforator flap can be designed according to the tissue defect, and used to repair the defect after advanced local lesions resection in PGC.

Comparison of Outcomes of the Radial Forearm Free Flap Vs Pectoralis Major Pedicled Flap for the Reconstruction of Oral Soft Tissue Defects

Introduction: Head and neck cancers are one of common cancers with peri oral cancers are more prevailing in areas with use of tobacco, ghutka and alcohol. Peri oral soft tissue defects can occur after tumor ablation or trauma. Objectives/Aim: To assess the flap survival and oral competence in radial forearm free flap versus pedicled pectoralis major myocutaneous flap. Method: A randomized control trial was conducted at Department of Plastic Surgery BVH, Bahawalpurfrom July 2019 to December 2020. A total of 60 patients were randomly divided in two equal groups. In Group A, radial forearm free flap and in Group B pedicledpectoralis major myocutaneous flap were used for reconstruction offull thickness defects. Data was entered and analyzed by using SPSS version 27.0. Mean and Standard Deviation were calculated for quantitative variables. Frequency and percentages were calculated for qualitative variables.Chi-square test was used to compare the flap survival and oral competence between the groups and p 0.05 which is not statistically significant. Results: The mean age of patients in group A was 47.47 ± 12.28 years and in group B was 48.40 ± 12.02 years. Out of 60 patients, 80%&amp; 60% of patients in group A &amp; B were males respectively. Partial Flap lossin group A was 6.67% and in Group B 10%. Overall flap survival was 93.33% in Group A &amp; 86.67% in Group B with the p &gt; 0.05 which is not statistically significant. Conclusion: Radial forearm free flap is comparable option for head and neck reconstruction to the pectoralis major myocutaneous flap with fewer complication rate and overall successful outcome.

Free Flap microvascular pharyngeal closure results in improved dysphagia-specific quality of life following total laryngectomy

BackgroundTotal laryngectomy (TL) as either a primary or salvage treatment strategy remains an effective oncologic operation in the management of laryngeal cancer. Dysphagia is the most common complication following TL and this has a significant impact on patients’ quality of life (QOL). Following removal of the larynx, a number of pharyngeal closure techniques exist. We aimed to evaluate the effect pharyngeal closure techniques have on dysphagia-specific QOL postoperatively.MethodsWe retrospectively reviewed patients who had undergone TL at our institution (2014–2019). Patients alive at the time of study were invited to complete the MD Anderson Dysphagia Inventory (MDADI). Outcomes were compared among Primary Closure (PC), Pedicled Pectoralis Major Myocutaneous Flap (PMMF) and Free Flap (FF) closure groups.ResultsThere were 27 patients identified for inclusion. Eight patients (30%) underwent PC, 10 patients (37%) had PMMF-assisted closure and 9 patients (33%) underwent FF-assisted closure. Patients within the FF group scored consistently higher MDADI scores across all subscales (emotional, functional, physical, global) as well as composite MDADI score in comparison to the PC and PMMF groups. FF closure was associated with a reduced inpatient length of stay (LOS). Additionally, no significant differences in postoperative morbidity including rates of pharyngo-cutaneous fistula (PCF) were observed between groups.ConclusionsWe now advocate FF closure for our patients following salvage TL due to the improved dysphagia-specific QOL, reduced inpatient LOS and lack of additional surgical morbidity.Level of evidence, Level III, therapeutic/prognostic study.

Hypopharynx reconstruction for primary hypopharyngeal carcinoma: a retrospective study and literature review.

BackgroundThe study aims to retrospectively evaluate disparate reconstructive choices for defects in patients with primary hypopharyngeal carcinoma undergoing tumor resection.MethodsOne hundred and twenty-five patients of primary hypopharyngeal carcinamo conducted with hypopharynx reconstruction for restoring the defects causing by tumor ablation from 2003 to 2016 at Eye & ENT Hospital of Fudan University were reviewed. Most of them were treated with the following three techniques (n=115): gastric pull-up (GPU), the pedicled pectoralis major myocutaneous flap (PMMF) and the radial forearm free flap (RFFF). GPU was used for those with cervical esophagus invasion requiring esophageal resection in our institution. We focus on the postoperative complication morbidity, function of deglutition 1 month after hospital discharge and disease-free survival (DFS) outcomes.ResultsOne month after operation, 56 of 65 (86.2%) achieved solid or semisolid diet with normal swallowing function for GPU, 8 of 12 (66.7%) for RFFF and 20 of 33 (60.6%) for PMMF respectively. Postoperative complications occured in 15 (23.1%), 8 (66.7%), 16 (48.5%) for GPU, RFFF and PMMF respectively, including flap/anastomotic necrsis, pharyngeal fistula, wound infection (both recipient and donor sites), pulmonary and cardiovascular complications.ConclusionsGPU showed satisfactory outcomes for reconstruction of patients with hypopharyngeal carcinoma requiring esophageal resection. For patients without cervical esophagus invasion and underwent partial or total pharyngectomy, both PMMF and RFFF can afford good coverage and reliable functional and survival outcome as well as postoperative complication morbidity. Moreover, the only predictive factor for incidence of postoperative complication was extent of surgery, as total hypopharyngectomy was more likely to develop complications after surgery than partial hypopharyngectomy.

A 19-Year Experience With Clavicular Defects: An Algorithm for Flap Selection and Surgical Outcomes.

The clavicle contributes to the stability and functional integrity of the shoulder. Clavicle bone defects are uncommon, and the strategy for their management is variable. Six patients presented with clavicle bone defects. The causes were as follows: traumatic defects (2 patients), electric injury (1 patient), osteoradionecrosis (2 patients), and nonunion (1 patient). One patient had upper limb palsy for 40 years, and another had posttraumatic shoulder function impairment. A pedicled pectoralis major myocutaneous flap was used for the patient with a dysfunctional limb, and 5 bone flaps (3 free fibular flaps, 1 free iliac flap, and 1 pedicled rib flap) were used for reconstruction in the other patients. All flaps (2 pedicled flaps and 4 free flaps) were successfully used for wound repair; the pedicled rib flap demonstrated partial marginal necrosis, and the free fibular flap required reexploration for venous kinking. Five functionally impaired upper limbs showed functional improvements postoperatively. For functionless composite clavicles and soft tissue defects, a soft tissue flap will be required for wound repair. A bone flap, especially a fibular flap, is required for the upper limb to show functional recovery. The variety of flaps will be planned according to the defect size comparison between the bone and soft tissue, and ipsilateral upper limb function, and a proposed algorithm will be discussed.

Cysticercosis Infested Pectoralis Major Myocutaneous Flap Reconstruction: An Ethical Dilemma.

Disseminated cysticercosis is a rare manifestation of cysticercosis, a relatively common tropical disease in Asia, Africa and South America. Here the embryo of pork tapeworm Taenia Solium gets disseminated to multiple organs and tissues via hepatoportal system. we report here a 45year gentleman with stage IV oral malignancy who was incidentally found to have disseminated cysticercosis on pre-operative work up. Along with the management of primary cancer and new found asymptomatic disseminated cysticercosis, the ethical challenge was to choose an appropriate reconstructive option for the composite oral cavity resection defect, since all the skeletal muscles in body where studded with cysticercosis larvae. We couldn't find any such report in literature to resolve our dilemma. After surgical board discussion, we zeroed down to pedicled pectoralis major myocutaneous flap, the most versatile and workhorse flap for head and neck reconstruction. Eventually the patient underwent surgery and adjuvant radiotherapy without any delay. He was simultaneously treated with oral albendazole under steroid cover and remained complication free at 2years.

Evaluating the free radial forearm flap versus the pedicled pectoralis major myocutaneous flap for oesophago-pharyngeal reconstruction: decision making, outcome and literature review

The successful reconstruction of oesophago-hypopharyngeal defects is a challenge and the choice of the best reconstructive option is still controversial. The purposes of this study were to evaluate the use of the free radial forearm flap (RFF) or the pedicled pectoralis major (PM) flap for oesophago-hypopharyngeal reconstruction and to review the literature, considering the free flap option as the state of the art. The decision making, outcome and common complications were assessed. From 2013 to 2018, 15 sequential patients with laryngeal carcinoma, 61 years and BMI 24.6, were included in this retrospective study. They underwent laryngectomy-pharyngo/esophagectomy and immediate or secondary pharyngoesophageal reconstruction. Nine patients underwent reconstruction with RFF (group A) and six with PM flap (group B). We excluded patients with history of thoracic and breast surgery and synchronous malignancy. We used the SPSS v.21 for statistical analysis. The duration of surgery for RFF was longer (731 min versus 435 min). Postoperatively, all patients received radiotherapy, whereas chemotherapy was administered in one patient. The RFF was the procedure of choice for stages III–IV and larger defects and the PM for stage II (p = 0.002). Overall complication rates, fistula, stricture and swallowing dysfunction were found higher in group B, but not significant (pCompl = 0.315, pFist = 1.000, pStrict/Swall = 0.143). Furthermore, the secondary PM reconstructions had non-statistically significant even higher fistula and swallowing dysfunction rates (p = 0.400). Both groups reported equal good results in terms of oral alimentation and speech. We found that the RFF and PM flap could provide comparable outcomes in oesophago-pharyngeal reconstruction. The RFF seems to be a superior reconstructive option for advanced disease and larger defects and is associated with better swallowing and fewer complications Level of evidence: Level III, therapeutic study.

Humongous Head-Neck Surgical Defect: a Reconstructive Challenge

Complex face and neck surgical defects poses reconstructive challenge particularly in tricky situations were prolonged ventilation is contraindicated. The result of an islanded, folded pedicled pectoralis major myocutaneous flap which is a reliable alternative to free flap is shown. A slight modification in conventional technique, where the flap is based solely on its sterno-clavicular fibers preserving the whole of its clavicular head creating a true island flap has been described.

Anterolateral thigh versus pectoralis major flaps in reconstruction of the lateral temporal bone defect.

Free tissue reconstruction is reliable in suitable patients but patient selection remains a challenge for the reconstructive surgeon. The anterolateral thigh (ALT) free flap and pedicled pectoralis major myocutaneous flap (PMMF) are two common reconstructive options for a lateral temporal bone resection defect. The threshold at which free tissue reconstruction should be considered over locoregional reconstruction is not defined. We sought to define reconstructive flap choice in the setting of medical comorbidities that may dissuade free tissue transfer. A retrospective analysis of lateral temporal bone defects at a single institution was undertaken. The primary outcomes were flap survival, surgical complications and durations of surgery and stay. Data regarding medical comorbidities and potential confounders were examined. Sixty patients with lateral temporal bone defects were identified. Twenty-four (40%) patients underwent PMMF reconstruction and 36 (60%) were reconstructed with ALT. The former were significantly older (73 versus 62 years), though with similar Anesthesiologists Risk Classification System status. Free-flap reconstruction resulted in significantly less flap loss (two versus six) but a longer operating time (790 versus 671 min). Patients suffering head and neck cancer with medical comorbidities can make selection of a suitable reconstruction difficult. We found that while patients undergoing ALT reconstruction were typically younger, the comorbidity profile of those patients was similar to patients undergoing PMMF reconstruction. ALT flaps were more reliable than the PMMF, lending credence to the view that free tissue transfer should be the preferred reconstructive option in suitable candidates and defects.

A modified pectoralis major myocutaneous flap technique with improved vascular supply and an extended rotation arc for oral defects: A case report

The pedicled pectoralis major myocutaneous (PMMC) flap is versatile, and is widely used for the treatment of surgical defects following oral cancer resection. Although free-tissue transfer of a vascularized free flap is often preferred, the clinical benefits of the PMMC flap should not be overlooked. The conventional technique of harvesting a PMMC flap involves a single vascular supply from the pectoral branch of the thoracoacromial artery. However, this approach compromises the distal skin island of the flap, and requires an indirect blood supply via communicating vessels, which increases the potential risk of partial distal flap necrosis. When harvesting a PMMC flap for oral and maxillofacial reconstruction, preservation of the lateral thoracic artery and use of the subclavian route are alternatives that ensure sufficient blood supply and an increased rotation arc. Such an approach enables the harvesting of a PMMC flap that can reach the entire oral cavity, including the infraorbital region, palate, middle pterygopalatine fossa and nasopharynx, with no risk of vascular insufficiency to the distal skin island. In conclusion, the technique described in the present study was able to improve the blood supply of the distal PMMC flap and increase its rotation arc.

Diagnostic Features and Management Strategy of a Refractory Case of Osteoradionecrosis of the Mandible - A Case Report

Introduction: Osteoradionecrosis of the jaws produces a considerable amount of esthetic as well as functional deficits, seriously affecting quality of life of the patient. Cases are often notoriously difficult to treat and manage owing to associated comorbidities of the patient, post irradiation fibrosis and decreased vascularity at the site, which complicates free tissue flap and graft transfer, that subsequently succumb to failure. Hyperbaric Oxygen Therapy (HBOT), in which 100% Oxygen is administered by mask under 2.4 Atm pressure, in a Hyperbaric oxygen chamber, helps by increasing local vascularity. Aim and methods: It was the aim of this study to show that a particularly refractory, compromised and challenging case of osteoradionecrosis can be managed successfully even without HBOT, by mandibular segmental resection followed by reconstruction using a titanium reconstruction plate enveloped within a pedicled Pectoralis Major Myocutaneous flap. Result: Post-operative recovery of the patient was excellent with good functional and esthetic rehabilitation of the patient with and practically nil donor site morbidity. Conclusion: It is important to have a thorough knowledge of the clinical, radiographic, histopathologic, CT and MRI features of osteoradionecrosis of the jaws in order to make a quick and accurate confirmatory diagnosis and to overcome possible diagnostic dilemmas.The strategy of reconstruction of a large mandibular defect using a bridging titanium plate sandwiched by a healthy vascularized myocutaneous flap, following ablative surgery for ORN, has proved to be a safe and reliable option for composite mandibular defects, with gratifying long term functional and cosmetic results.

A Novel Technique to Increase the Length of Tracheal Resection by Adding an Autologous Pedicled Pectoralis Major Myocutaneous Flap Transposition

Resection of the trachea is usually limited by the length of involvement. We present a case of long segment tracheal resection performed by adding an autologous pedicled pectoralis major myocutaneous flap transposition. By applying of this technique, a segment of trachea as long as 7.5 cm was safely resected without complications.

Active Middle Ear Implant After Lateral Petrosectomy and Radiotherapy for Ear Cancer

Tumor of the temporal bone is a rare disease with a very poor prognosis. Surgery and postoperative radiotherapy are usually the recommended treatments for squamous cell carcinoma (SCC) of the external and middle ear, which may cause conductive hearing loss. The purpose of this study was to evaluate the audiologic results and compliance of active middle ear implant (AMEI) and establish the feasibility of the procedure in a patient treated for middle ear cancer. A 73-year-old patient treated with lateral petrosectomy, neck dissection, reconstruction/obliteration by pedicled pectoralis major myocutaneous flap, and postoperative full dose radiotherapy for external and middle ear SCC was selected for AMEI. Preoperative audiometric and speech audiometry tests were performed on both ears before and after the activation. Pure tone free field audiometry. Binaural free field speech audiogram. Aided pure tone free field audiometry AMEI results show an increase in air conduction. Speech audiogram showed better discrimination scores in AMEI-aided situations. No complications were observed. AMEI after surgery followed by radiotherapy for middle ear cancer is feasible. Acoustic results in obliterated ear are satisfactory.
