Pectoral major myocutaneous flap in our practice: about 25 cases.

The pectoralis major myocutaneous flap (PMMF) was described by Ariyan in 1979 for head and neck reconstructions. It is a safe flap, currently supplanted by free flaps in developed countries, but which remains very useful in developing countries. We report a series of 25 cases of PMMF reconstruction. All patients were treated for advanced stages of oral cavity cancer, where tumor excision left significant tissue loss. The reconstruction used PMMF, taken using the same technique. Supplanted by free flaps in developed countries, PMMF remains useful in developing countries. It is a flap that has numerous advantages (ease of collection, viability, low requirements in terms of instrumentation, etc.). Many variations have been described over the years.

Bilobed Pectoralis Major Myocutaneous Flap Reconstruction: a Single Institution Experience of 150 Patients and Methods to Prevent Complications.

Introduction: Bilobed PMMC flap is done for patients who have diseases that require resection of oral cavity mucosa along with the overlying skin, either because of direct tumor invasion to the skin or for achieving adequate tumor-free base of resection. The versatility of the flap allows it to be used to cover both inner and outer linings for a full-thickness defect. Materials and Methods: This was a single-center, retrospective, observational study carried out in the Department of Head and Neck Oncology at a regional cancer center from January 2019 to December 2019. A minimum follow-up duration for all patients was 6 months. The primary endpoint was to study the results and complications associated with bilobed PMMC flap reconstruction and factors affecting it, as well as their management. Results: The median age was 45 years [24-71 years]. There were 96(64%) males and 54(36%) females. The most common sites reconstructed were lower gingivobuccal sulcus (39.1%), buccal mucosa (30.2%), and lower alveolus (16.7%). The overall complication rate was 41.3%, with 10(6.6%) patients requiring re-exploration. The average hospital stay was 11 days [5-28 days]. On doing a multivariate analysis, for various factors affecting flap necrosis, none of the factors reached statistical significance (p value > 0.05). Conclusion: PMMC flap remains the workhorse of head and neck reconstruction. In cases of full-thickness defects in oral cancer patients, in our country, in the setup which lacks the expertise in microvascular anastomosis and with immense caseload in the head and neck cancer department, bilobed PMMC flap remains a safe and favorite alternative method for reconstruction.

Bipaddle Pectoralis Major Myocutaneous Flap (PMMC) for Complex Composite Oral Cavity Defects: An Experience of a Tertiary Cancer Centre.

Although microvascular free flaps are considered the first choice in head and neck cancer defect reconstruction, their use is limited in developing regions by availability of resources and the expertise .The Bipaddle pectoralis major myocutaneous flap (PMMC flap) is a commonly used flap in head and neck cancer reconstruction, but in literature flap is associated with high incidence of drawbacks including donor site morbidity and added bulk of the flap reducing cosmetics and function. The purpose of the study is to evaluate the Bipaddle PMMC flap reliability, operative technique and outcome in reconstructive head and neck cancer surgery in the era of microvascular free flaps. Its a prospective study in which the records of 50 patients treated with Bippadle PMMC flap reconstruction between January 2022 to July 2022 were systematically collected and reviewed. Data of recipient site, serum albumin, history of adjuvant, recurrence, defect dimension, type of donor site closure, length of hospital stay, postoperative complications and outcomes were analysed. There were 45 males and 5 females with a mean age of 41 years (31-60). Bipaddle PMMC flap reconstruction was done in all patients of advanced squamous cell carcinoma of oral cavity. There were two males with complete necrosis of flap salvaged with latissimus dorsi flap and forehead flap. Minor infections were noted in two female and one male patient, managed conservatively and recovered well with acceptable final outcome. The Bipaddle PMMC flap is reliable for large defects in head and neck reconstructive surgery, particularly when a bulky flap is required to reconstruct composite defects where the lesion is involving the skin. Placing the flap horizontally with inclusion of nipple and areola in most of the patients increased the reach and size of available flap.

Submammary Approach for Harvesting Pectoralis Major Myocutaneous Flap in Females with Oral Cavity Cancers: Report of Technique and Our Experience.

Background: Oral squamous cell carcinoma is one of the most common types of cancers affecting both male and female population worldwide. Currently gold standard for reconstruction of oral cavity defects is free flap reconstruction. However, in developing countries due to large case load, infrastructural and resource constraints, Pectoralis major myocutaneous flap is still widely being used. Harvesting PMMC flap in females is challenging due to thick fat and breast tissue affecting its reliability and also increased donor site morbidity. This article aims at highlighting our experience with harvesting PMMC flap in female patients by submammary approach and its outcomes. Methods: A total of 23 female patients who underwent wide local excision of oral cavity cancers and reconstruction with PMMC flap were included. Data was analysed as mean, median, mode, percentages and statistical averages. Results: Majority of patients belonged to 40-60 years of age group (60.86%). Buccal mucosa was the most common site of primary lesion in 16 patients (69.56%). Out of the 23 patients who underwent PMMC flap reconstruction, recipient site complications were seen in 4 patients including total flap loss in 2 patients (8.69%), minor complications, e.g. infection in 2 patients (8.69%). Donor site morbidity in the form of axillary seroma was seen in only 1 patient (4.34%). Conclusion: In our experience, PMMC flap is still a viable option for reconstruction especially in resource constraint settings. Submammary approach to PMMC flap harvest is a safe technique as it is associated with minimum recipient site complications whilst preserving donor site anatomy and thereby reducing donor site morbidities to minimum.

Pedicled flaps reconstruction of hypopharynx and laryngeal defects: Successful preservation of laryngeal function in patients with advanced hypopharyngeal cancer.

BACKGROUND: Preserving laryngeal function and reconstructing the hypopharynx in advanced hypopharyngeal cancer pose significant challenges for head and neck surgeons. METHODS: A 48-year-old male patient was diagnosed with advanced hypopharyngeal cancer originating from the left pyriform sinus. The tumor extended into the hypopharynx, left vocal cord, ventricular fold, partial aryepiglottic fold, and a segment of the cervical esophagus. A curative tumor resection was performed, and a well-thought-out strategy was employed for hypopharyngeal repair and laryngeal reconstruction. RESULTS: Following the surgery, the patient demonstrated exceptional flap survival, and the tracheostomy tube was removed at the 6-month mark. No surgery-related complications were observed, and both swallowing and vocal functions exhibited a robust recovery. CONCLUSION: Our reconstruction strategy proves effective in preserving laryngeal function among patients with advanced hypopharyngeal cancer.

'AJ's Orbicularis Oris Stitch: A Novel and Simple Technique of Reconstructing Central Arch Mandibular Defects in Resource-Constrained Set Up'.

Lip and oral cavity SCC account for 2nd highest incidence of cancers and 3rd most common cause of mortality from cancer in India. Reconstruction of defects of central arch invading cancers results in poor cosmetic and functional outcomes if free flaps are not used. 30 patients with Oral SCC in the age group 20-75 years requiring central arch segmental mandibulectomy were included. Reconstruction was done with pedicled bipaddled PMMC flap with 'AJ's orbicularis oris stitch' using Fiber wire. Patients were divided into 4 groups according to extent of lip and skin loss post excision of primary tumour. Patients were evaluated with subjective scores for drooling, oral competence and cosmesis. There were 4, 12, 9 and 5 patients in Group A, B, C and D respectively. Mean subjective scores using our technique for drooling, oral competence and cosmesis were 3.75/4,3.75/4 and 3.5/4 for group A, 3.45/4, 3.36/4 and 3.09/4 for group B, 2.8/4, 2.6/4 and 2.3/4 for group C defects and 2.5/4, 3/4 and 2.5/4 for group D defects respectively. Over all scores for all patients were 3.2/4, 3.14/4 and 2.84/4 for drooling, oral competence and cosmesis. This simple, quick and inexpensive technique of reconstruction of central mandibular arch defects can drastically improve cosmetic and functional outcomes in a resource restrained set up. However, long term results and comparison studies are required for standardisation of the technique.

"Flap of Hope: a Pectoralis Major Muscle Solution for Tracheal Resection Closure": Case Report.

Medullary carcinoma of the thyroid is a rare type of thyroid cancer that arises from the parafollicular cells or C-cells, which produce calcitonin. It accounts for approximately 5-10% of all thyroid cancers (Leboulleux et al. in Clin Endocrinol 61(3):299-310, 2004). The main treatment for medullary thyroid carcinoma is surgery, which involves the removal of the thyroid gland and any affected lymph nodes. In advanced cases where the cancer has spread to nearby structures such as the trachea (Gupta et al. in Indian J Surg Oncol 11(1):75-79, 2020), tracheal resection followed by reconstruction may be necessary to remove the cancer (Chernichenko et al. in Curr Opin Oncol 24(1):29-34, 2012) and restore proper breathing, closure of large tracheal defect can be done with pectoralis major myocutaneous flap (Salmerón-González et al. Plast Surg Nurs 38. 162-165, 2018). In this article, we report a case of recurrent medullary carcinoma thyroid with tracheal infiltration and tracheal resection was done, both of which is extremely rare. A 38-year-old male patient with a history of total thyroidectomy presented with recurrence was referred to our department, his previous biopsy and IHC revealed medullary carcinoma thyroid. Ga-68 DOTA PET CT scan was done which showed PET avid residual mass over right side, multiple bilateral cervical nodes, and tracheal infiltration (Fig. 1) then underwent a bronchoscopy showing involvement of the second, third, and fourth tracheal ring. Bilateral neck dissection with sleeve resection of trachea with overlying residual tumor was done and was sent for frozen which revealed positive margins and re-excision of margins was done, which lead to large defect (Fig. 2) which could not be closed primarily with a Montgomery T Tube. A de-epithelized pectoralis major myocutaneous flap used to close the tracheal defect followed by placing the Montgomery T Tube (Fig. 3).Post-operative period was uneventful. The final histopathology report showed R0 resection of tumor. T tube was removed after 4 weeks.

Pedicled thoracoacromial artery compound flaps for circumferential hypopharyngeal reconstruction.

BACKGROUND: Total laryngeal and hypopharyngeal resection remained to be the mainly treatment option for advanced hypopharyngeal cancer, which resulted in complicated reconstructive challenge for circumferential hypopharyngeal defect. The pedicled thoracoacromial artery compound flaps included Thoracoacromial artery perforator (TAAP) flap and pectoralis major myocutaneous (PMMC) flap. This study is to evaluate the clinical application of the pedicled thoracoacromial artery compound flaps for circumferential hypopharyngeal reconstruction. METHODS: From May 2021 to April 2022, four hypopharyngeal cancer patients with circumferential hypopharyngeal defects were reconstructed by the pedicled thoracoacromial artery compound flaps. All patients were males. Patient age ranged from 35 to 62 years (average, 50 years). The Shoulder function were evaluated by SPADI. The average follow-up was 10.25 months (range from 4 to 18 months). RESULTS: All of the pedicled thoracoacromial artery compound flaps in our study survived. The defect length between tongue base and cervical esophagus ranged from 8 to 10 cm after total laryngeal and hypopharyngeal resection. The TAAP flap size ranged from 6 × 7 cm to 7 × 10 cm, and the PMMC flap size ranged from 6 × 7 cm to 9 × 12 cm. The pedicle length of TAAP and PMMC flaps varied, respectively, from 5 to 8 cm (mean 6.5 cm) and 7 cm to 11 cm (mean 8.75 cm). The mean time of TAAP and PMMC flaps harvest was, respectively, 82 min and 39 min. All patients were able to resume soft diet in the fourth week of postoperation, but one patient was operated by gastrostomy in the second month of postoperation because of pharyngeal cavity stenosis, and the patient successfully resumed oral soft diet by endoscopic balloon dilation after postoperation radiotherapy. All patients have resumed oral feeding at last. There were mild dysfunction for our patients according to SPADI during the mid-long follow-up. CONCLUSIONS: The pedicled thoracoacromial artery compound flaps have stable blood supply and provide adequate muscle coverage for greater protection during radiotherapy, and the microsurgical skills have no requirement. Therefore, the compound flaps provide a good choice for the reconstruction of circumferential hypopharyngeal defect, especially in the aged or patients with comorbidities who are not able to tolerate prolonged surgery.

Bipaddled Pectoralis Major Myocutaneous Flap in Complex Oral Cancer Defects- A Single Center Experience with Quality of Life Assessment.

Introduction: Advanced stage malignancies of oral cavity commonly result in complex full thickness defects with subsequent functional and aesthetic loss. Through this article we describe our center's experience in reconstruction of such defects with bipaddled pectoralis myocutaneous (PMMC) flap through an immediate, single-staged procedure. Materials And Methods: The study included a total of 54 patients who underwent composite resection and neck dissection followed by reconstruction of the defect with bipaddled PMMC flap. All patients were followed up post-operatively for 1 year and were monitored for flap and donor site related complications. Using University of Washington Quality of life v4 questionnaire (UW-QOL4), we assessed the QOL of 54 patients. The mean scores were compared to other similar studies. Results: The overall complication rate was 66.6%, whereas, 33.3% patients had no complications. The most common complication was wound dehiscence seen in 31.5% of cases in the recipient site and 12.9% in the donor site. Other complications were seroma, hematoma, plate exposure, orocutaneous fistula etc. Around 73.7% patients reported a good, very good or outstanding overall quality of life in the post-operative period. The mean composite QOL score was 65.84. Our study showed comparable domains of pain, appearance, activity, recreation, swallowing, chewing, speech, shoulder function and taste with other similar studies. Conclusion: Bipaddled PMMC flap proves to be a considerable alternative for microvascular free flaps in reconstruction of full-thickness defects of oral cavity owing to its reliable blood supply, accessibility, easier harvesting technique, cost effectiveness, high success rate and acceptable quality of life.

Pectoralis Major Myocutaneous Flap Revisited as a Workhorse for Reconstruction for Defects in the Upper Arm: A Case Report.

Many previous reviews of the literature have described the grafts and techniques for management of defects in the upper arm. However, the alternatives are limited in cases where some conventional flaps are not available and the nearby donor vessels have been previously sacrificed for free flaps. A 77-year-old man presented with a tumor in the right upper arm just above the axilla. The patient had already undergone surgeries for three recurrences of low-grade myxofibrosarcoma, the primary site of which was around the right scapula. The pectoralis major musculocutaneous flap was used for the defect caused by tumor resection, since there was no other available option. An acceptable result was obtained without any major complications. Thus, the pectoralis major myocutaneous flap may be a candidate for reconstruction of defects in the proximal part of the upper arm.

Delayed Partial Venous Insufficiency of Free Flap: To Intervene or Not?

Delayed venous congestion of a free flap poses a dilemma for clinicians, as the optimal management strategy is often uncertain. This case report presents a successful outcome achieved through a strategy of watchful waiting for a delayed presentation of a partially congested free flap. This approach enabled the avoidance of unnecessary surgical interventions and minimized potential complications associated with flap exploration. By adopting a watchful waiting strategy, clinicians can navigate the challenging decision-making process in cases of partial venous congestion of free flaps, optimizing patient outcomes.

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 45 year 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 2 years.

Does Pectoralis Major Myocutaneous Flap Cause the Shoulder Morbidity: A Clinical Comparative Study.

The aim was to compare the morbidity of shoulder function following modified radical neck dissection with and without Pectoralis Major Myocutaneous muscle flap (PMMC) harvest in head and neck cancer patient to determine the effect of PMMC flap harvest on shoulder function and also to determine the effect of physiotherapy. Materials and methods: Prospective study involving two groups study group of 20 patients with MRND, with PMMC flap reconstruction as part of head and neck cancer surgery and control group of 20 patients who had undergone MRND(IJV & SAN sparing) without PMMC flap in same period were included. All patients were assessed at 3rd and 6th month following completion of surgery using subjective (Shoulder Disability Questionnaire) and objective (goniometer and manual muscle testing) parameters. 40 patients were included in the study, 33 (82.5%) male and 7 (17.5%) female with a mean age of 49 years with stage III/IV carcinoma In Group-1 and Group-2 the shoulder disability decreased significantly after physiotherapy intervention and also at 6thmonth postoperatively both groups showed improvements in shoulder range of motion and muscle strength. Harvesting of PMMC flap does not intensify the morbidity of shoulder which is common in RND and during MRND. A regimen of home-based exercises and patient education are effective tools to reduce shoulder disability and improving shoulder function.

Comparison of Functional and Survival Outcomes in Pedicled and Microsurgical Flap Reconstruction for Near-Total and Total Glossectomies.

Introduction: Patients with advanced carcinoma tongue end up with near-total/total glossectomy (NTG/TG). We intended to compare functional, oncological, and survival outcomes of patients undergoing pedicled and microsurgical flap reconstruction in NTG/TG patients at our hospital. Methodology: A prospective study was conducted for 7 years on 91 patients with carcinoma tongue who underwent NTG/TG at our institute. Patients underwent anterolateral thigh (ALT), free radial artery forearm flap (FRAFF), and pectoralis major myocutaneous (PMMC) flap reconstruction and were followed up for immediate complications and functional outcomes for speech, swallowing, and decannulation after completion of adjuvant treatment and then for survival rates for a period of 60 months and statistically analysed with log rank test and Fisher's exact test for correlation. Results: Ninety-one (42.85%) patients underwent NTG, while 57.14% underwent TG. 85% of patients had >5 mm margin, 14% had ≤ of 5 mm, and none were positive. 57% of patients did not have postoperative complications and 10% underwent re-exploration. During follow-up, 85.7% of patients were able to take orally: 52% soft diet and 32% liquid diet. Multivariate analysis of individual flaps, swallowing, and speech intelligibility values were significant. After 5 years of postadjuvant therapy, there was 76% overall survival, 11% local recurrence and 12% had regional recurrence. Discussion: Morbidity and functional outcome depends on the extent of resection. PMMC flaps can be done on lack of expertise. FRAFF has better functional outcomes owing to pliability of flap. ALT and other bulky flaps require expertise and are prone to flap-related complications. Planning of reconstruction should be based on the defect size together with counseling of patients regarding the risk of complications and delay in adjuvant therapy.

Mango-shaped Bi-paddled pectoralis major myocutaneous flap reconstruction for large full-thickness defects post resection of squamous cell carcinoma of oral cavity: An analysis of 232 cases.

Objectives: The objective of the study was to examine the feasibility of bi-paddled pectoralis major myocutaneous (PMMC) flap reconstruction in patient undergoing full thickness composite resection. Materials and Methods: Inclusion criteria: The subjects chosen were patients with clinically T4A squamous cell carcinoma of buccal mucosa, lower alveolus, and maxilla in with skin involvement. Patients required a full-thickness composite resection of intraoral lesion, bone (mandibular segment and/or maxilla), and overlying involved skin and had modified radical neck dissection. Exclusion criteria: Patients not requiring full thickness composite resection including skin. Patients were observed postoperatively for early and late postoperative complications, starting of oral feeding, post-operative trismus, and dysphagia during subsequent follow-up and cosmetic outcome. Results: Overall, the complication rate was 33.8% out of which only 7.8% required major re-surgery with second flap reconstruction. This is comparable with other large series of PMMC flap. Clavien-Dindo Grade I complications were seen in 9.5%, Grade II in 69.7%, Grade IIIA in 13.4%, and Grade IIIB in 7.45% of patients. Full-thickness partial flap necrosis included necrosis of either the external or the internal skin paddle. There were 15 cases - 6.5% of full thickness external paddle necrosis. These were mostly in patients with bite composite resections and having a larger random fasciocutaneous distal component of the flap without underlying muscle. Furthermore, 40% of these patients were females. In females, the flap necrosis comprised 4 of the 12 patients (33.33%). Conclusion: Pectoralis major mycocutaneous flap has been a boon to reconstruction of the oral cavity post its inception. In case of locally advanced squamous cell carcinomas of the oral cavity, in many instances, there is a clinically significant cervical lymph nodal spread vessels post mandating a comprehensive lymph node dissection. PMMC flap provides a robust well vascularized muscular cover to the cervical vessels poststernocleidomastoid excision.

Modified Technique of Pectoralis Major Myocutaneous Flap Inset for Buccal Mucosa Reconstruction.

BACKGROUND: Conventional technique of flap inset in buccal mucosa reconstruction is by direct suturing of cutaneous margin of Pectoralis Major Myocutaneous (PMMC) flap to hard and soft palate mucosa and margin of floor of mouth with simple interrupted sutures. We have done a prospective study of the efficacy of anchoring the upper margin of PMMC flap to the hard palate by a modified method in reconstruction of buccal mucosa defects following tumour excision. This is to prevent disruption of suture line from the mucoperiosteum of hard palate and resultant oro-cutaneous fistula. METHODS: This hospital-based prospective study was carried out in the Department of Plastic Surgery at Bangalore, India for a period of 18 months (2015-2017). Patients (N=48) with buccal mucosa defects requiring reconstruction with PMMC flap either with conventional (n=24) or modified method (n=24) following tumour excision were included. Clinico-demographic profile of the patients including age, gender, size of defect, staging of illness, site and type of reconstruction, disruption of suture margin in the hard palate, development of oro-cutaneous fistula (OCF), day of starting oral feeds, removal of Ryle's tube and post-operative average length of stay in the hospital were recorded. RESULTS: Disruption of suture line in hard palate and Oro-cutaneous fistula were statistically significant in study group in both the variables (P-0.033, P-0.033). The median days on which patients were started with oral clear liquids and removal of Ryle's tube were also statistically significant between study and control groups. Post-operative average length of hospital stay which is the outcome of favourable results in the study group was found to be statistically significant (P-0.021) between the groups. CONCLUSION: Overall, modified technique of anchorage of PMMC flap can be considered as a reliable technique in buccal mucosa reconstruction because of its stability, lower complication rates and shorter length of hospital stay.

Utilization of non-vascularized bone graft with regional flap as an alternative for facial reconstruction.

Mandibular resections decision is one of the most important steps in oral cavity malignant or nonmalignant lesions associated with the mandible. The role of mandibular reconstruction is not only for cosmesis, but it is also indicated for functional rehabilitation such as swallowing, phonetics, and for facial symmetrical. Even though the free tissue transfer is considered a gold standard for mandibular reconstruction, the importance of nonvascularized bone grafts (NVBGs) such as fibula, calvarium, rib, sternum, and iliac are still persisting in mandibulectomies condition like patient who have not taken radiotherapy or not willing to undergo radiotherapy or not fit for free tissue transfer and provides a good contour of mandibular replacement. The success rate of NVBG depends upon patient selection, preoperative planning, and meticulous nursing care. Addition to NVBG, regional flaps such as pectoralis major myocutaneous (PMMC) flap will help in soft-tissue replacement of the defect as well as it will help in the situation where primary closure and airtight closure is not possible. This case report will discuss in detail about the management of anterior segmental mandibulectomy due to oncological resection and reconstruction with NVBG with fibula and PMMC.

Single Stage Reconstruction of Full Thickness Defects of Cheek with Pectoralis Major Myocutaneous Flap Using an Innovative Flap Technique.

The purpose of this article is to present an innovative technique in harvesting the pectoralis major myocutaneous flap (PMMC) which is very useful for reconstruction of post-ablative full thickness defects of cheek in elderly female patients. This is a prospective study of patients who underwent reconstruction with PMMC flap for post-ablative full thickness defects of the cheek and mandible in a tertiary cancer center over a period of 36 months. Sixty patients were included in the study. Mean duration of the hospital stay was 12 days. Eight patients (13.33%) had minor wound dehiscence, 6 (10%) had marginal skin necrosis of the flap, 2 (3.33%) patients had venous congestion, and 4 (6.66%) had wound dehiscence at the palate. Four (6.66%) patients had a gradual necrosis of the outer paddle. Our modification of elevation of the PMMC flap prevents its shearing which is especially useful in raising this flap in elderly female patients affected with advanced oral cancer.

Combined Use of Pectoralis Major Myocutaneous Flap and Deltopectoral Flap for the Reconstruction of Advanced Oral Cancers: Our Experience in 29 Cases.

Purpose: To assess the utility of the combined use of pectoralis major myocutaneous (PMMC) flap and deltopectoral flap (DP) in advanced oral cavity cancers in the Indian population. Materials and Methods: It is a retrospective study, considering 29 patients with stage IV carcinoma of the oral cavity, from July 2015 to February 2019. Both pectoralis major Myocutaneous flaps and deltopectoral flaps were used for stage IV oral cancers involving the full-thickness cheek and the mandibular cortex. The reliability of the flaps and clinical outcomes were evaluated in the postoperative period. Results: Of the 29 patients, partial necrosis of the skin island was detected in 6 patients, 2 patients presented with wound dehiscence, and one patient had an orocutaneous fistula. Recurrence was detected in 3(10.34%) patients, in one patient, it was at the primary site and in 2 patients, it was in the neck. When different parameters were compared between the patients with complications and without complications, the comorbidities like smoking and alcohol intake adversely affected the flap survival in the postoperative period. Conclusions: The combined use of PMMC and DP flap can be a reliable option for advanced oral malignancies, especially in patients with poor performance status with the coexisting chronic illness. Due to the presence of a definite vascular pedicle, ease of harvesting the flap, quick surgical procedure, and the minimal postoperative morbidities, these pedicle flaps can be successfully used alternative to the free flaps in advanced oral cancers, especially patients with a low socioeconomic corridor like India.

Analysis of the efficacy of the pectoralis major myocutaneous flap in reconstructive head and neck surgery.

INTRODUCTION: Although free flaps have been used predominantly in past decades for the soft tissue reconstruction of head and neck malignancies, Pectoralis major myocutaneous flap (PMMF) is still a reliable workhorse for patients with co-existing co-morbidities or low economic status where free flaps are not feasible. PATIENTS AND METHODS: It was a retrospective study done on 36 patients of head and neck malignancies over the period of 5 years in which PMMF was used as a method of reconstruction in our hospital. Patients were followed up for a period of one year and outcome of PMMF was evaluated. RESULTS: Out of 36 patients 31 were of oral cancer and 5 were of carcinoma hypopharynx. Incidence of total flap necrosis was nil and partial flap necrosis was 16.6%. Orocutaneous fistula was found in 16.6%, wound dehiscence was in 19.4% and infection was found in 13.5% of patients. Non-flap related complications were found in 13.8% of patients. 35 out of 36 patients (97.2%) eventually achieved satisfactory surgical outcome of PMMF reconstruction. CONCLUSION: PMMF is a reliable method of reconstruction for head and neck malignancies especially in basic healthcare settings. With minimal expertise and groundwork, it is still a cost-effective workhorse flap for head and neck reconstruction.
