Abstract
Importance Lymph node metastases from oral cavity cancers are seen frequently, and there is still inconsistency, and occasional controversies, regarding the surgical management of the neck in patients with oral cancer. This review is intended to offer a surgically focused discussion of the current recommendations regarding management of the neck, focusing on the indications and extent of dissection required in patients with oral cavity squamous cell carcinoma while balancing surgical risk and oncologic outcome. Observations The surgical management of the neck for oral cavity cancer has been robustly studied, as evidenced by substantial existing literature surrounding the topic. Prior published investigations have provided a sound foundation on which data-driven treatment algorithms can generally be recommended. Conclusions Existing literature suggests that patients with oral cavity cancer should be fully staged preoperatively, and most patients should receive a neck dissection even when clinically N0. Quality standards supported by the literature include separation of each level during specimen handling and lymph node yield of 18 or more nodes. Sentinel lymph node biopsy can be considered in select tumors and within a well-trained multidisciplinary team.

Survival Outcomes in T3 Laryngeal Cancers: Primary Total Laryngectomy vs. Concurrent Chemoradiation or Radiation Therapy-A Meta-Analysis. Biomedicines 2023; 11:2128. [PMID: 37626625 PMCID: PMC10452463 DOI: 10.3390/biomedicines11082128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 07/22/2023] [Accepted: 07/25/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND The management of cT3 laryngeal cancers remains controversial, with studies recommending surgical or non-surgical approaches. Despite the many papers that have been published on the subject, there is a lack of studies showing which treatment has better results in terms of survival. OBJECTIVE To determine the difference in survival outcomes following total laryngectomy (TL), concurrent chemoradiation (CRT) or radiation therapy (RT) alone in T3 laryngeal cancers. METHODS Search of PubMed, Scopus, and Google Scholar databases from 1995 to 2023 employing specific keywords and Boolean operators to retrieve relevant articles. Statistical analysis was conducted using a random-effects model, and heterogeneity was evaluated using the Q-test and I2 statistic. Funnel plot asymmetry was assessed using rank correlation and regression tests. RESULTS The qualitative data synthesis comprised 10,940 patients from 16 included studies. TL was performed in 2149 (19.4%), CRT in 6723 (61.5%), RT in 295 (2.7%), while non-surgical treatment was not specified in 1773 (16.2%) patients. The pooled 2-year overall survival (OS) rates were TL = 73%, CRT = 74.7%, RT = 57.9%, 3-year OS rates were TL = 64.3%, CRT = 62.9%, RT = 52.4%, and 5-year OS rates were TL = 54.2%, CRT = 52.7%, RT = 40.8%. There was a significant heterogeneity in the included studies. There was no statistically significant difference in 2-year OS (logOR= -0.88 (95% confidence interval (CI): -1.99 to 0.23), p = 0.12), 3-year OS (logOR = -0.6 (95% CI: -1.34 to 0.15), p = 0.11), and 5-year OS (logOR = -0.54 (95% CI: -1.29 to 0.21), p = 0.16) between TL and CRT. Instead, there was significant difference in 2-year OS (logOR= -1.2383 (95% CI: -2.1679 to -0.3087), p = 0.009), 3-year OS (-1.1262 (95% CI: -1.6166 to -0.6358), p < 0.001), and 5-year OS (-0.99 (95% CI: -1.44 to -0.53)), p < 0.001) between TL and RT alone. CONCLUSIONS AND SIGNIFICANCE TL followed with adjuvant (chemo)radiation on indication and CRT with salvage surgery in reserve appear to have similar OS outcomes. Both resulted in better OS outcomes compared to RT alone in the treatment of T3 laryngeal cancers. If patients are unfit for chemotherapy, making CRT impossible, surgery may become the choice of treatment.

Real world data on long term outcome of neoadjuvant chemotherapy in locally advanced esthesioneuroblastoma and sinonasal tumor with neuroendocrine differentiation - Results from a single centre study. Oral Oncol 2023; 144:106486. [PMID: 37413771 DOI: 10.1016/j.oraloncology.2023.106486] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/03/2023] [Accepted: 06/29/2023] [Indexed: 07/08/2023]
Abstract
INTRODUCTION Esthesioneuroblastoma and sinonasal neuroendocrine carcinoma (SNEC) are the most common histological subtypes of non-squamous Sinonasal Tumors. A multidisciplinary approach is preferred for locally advanced unresectable esthesioneuroblastoma and SNEC. METHODS From June 2010 to October 2021, 59 patients with esthesioneuroblastoma and SNEC received NACT. NACT consists of 2-3 cycles of Etoposide-Platinum based chemotherapy. Depending upon response and performance status, subsequent therapy was planned. SPSS descriptive statistics were performed for analysis. Kaplan Meir methods were used for the estimation of Progression Free Survival (PFS) and Overall Survival (OS). RESULTS 45 (76.3 %) Esthesioneuroblastoma and 14 (23.7 %) SNEC patients received NACT. The median age of the population was 45 years (range 20-81 years). The majority of patients received 2-3 cycles of Platinum (Cisplatin or Carboplatin) + Etoposide as NACT. 28 patients (47.5%) underwent surgery and 20 patients (33.9%) received definitive chemoradiotherapy after NACT. The most common grade 3 or above adverse events were anemia (13.6%), neutropenia (27.1), and hyponatremia (45.8%). At the time of analysis, the median PFS was 56 months (95% CI 31 months to 77 months), and the median OS was 70 months (95% CI 56 months to 86 months). The most common late toxicities noticed were metabolic syndrome (42.4%), hyperglycemia (39%), nasal bleeding (33.9%), hypertension (17%), dyslipidemia (8.5%), and hypothyroidism (5.1%). CONCLUSION The study shows that NACT is safe, and can be easily delivered without any life-threatening toxicities, with a favorable response and improved survival in this subset of patients.

Abstract
Introduction Sinonasal carcinomas are a rare type of head and neck malignancy with various histologies. The outcomes of patients with unresectable locally advanced sinonasal carcinomas are poor. Hence, we performed this analysis to study the long-term outcomes of sinonasal adenocarcinoma (SNAC) and sinonasal undifferentiated carcinomas (SNUC) where neoadjuvant chemotherapy (NACT) has been given followed by local therapy. Methods 16 patients with SNUC and adenocarcinoma who received NACT were found eligible for the study. Descriptive statistical analysis was performed for baseline characteristics, adverse events and treatment compliance. Kaplan Meir methods were used for the estimation of progression-free survival (PFS) and overall survival (OS). Results Seven (43.75%) adenocarcinoma and nine (56.25%) SNUC patients were identified. The median age of the whole cohort was 48.5 years. The median number of cycles delivered was 3 (IQR 1-8). The incidence of grade 3-4 toxicity (CTCAE version 5.0) was 18.75%. The response was partial response or better in seven patients (43.75%). Post-NACT 11 patients (n = 15, 73%) were eligible for definitive therapy. The median PFS was 7.63 months (95% CI, 3.23 - NA months) and the median OS was 10.6 months (95% CI, 5.2-51.5 months). Median PFS and OS for those who underwent surgery post-NACT versus those who did not undergo surgery were 36.267 versus 3.7 months (p = 0.012) and 51.5 versus 10.633 months (p = 0.190), respectively. Conclusion The study shows a favourable role of NACT in improving resectability, significant improvement in PFS and non-significant improvement in OS after surgery.

Abstract
AbstractOral cavity cancers contribute to a majority of cancers in India. Clinical examination alone cannot determine the deeper extent of the disease; therefore, need for cross-sectional imaging including computed tomography and magnetic resonance imaging becomes indispensable for pre-treatment evaluation to decide optimal plan of management. Oral cavity squamous cell cancers (OSCC) can be treated with surgery alone, whereas deep muscle, neurovascular, osseous, or nodal involvement on imaging suggests advanced disease that requires a combination of surgery, radiation, and/or chemotherapy. Because of the complex anatomy of the oral cavity and its surrounding structures, imaging is crucial for locoregional staging and early detection of distant metastases. Imaging plays indispensable role not only in diagnosis but also in planning the management. An optimal guideline paper for developing countries like India is lacking that not only helps standardize the management but will also assist oncologists make reasonable decisions and reduce the unnecessary imaging. This imaging guideline paper will discuss the optimal imaging in diagnosis and management OSCC for Indian subcontinent.

Abstract
PURPOSE There is a lack of published literature on systemic therapeutic options in cisplatin-ineligible patients with locally advanced head and neck squamous cell carcinoma (LAHNSCC) undergoing chemoradiation. Docetaxel was assessed as a radiosensitizer in this situation. METHODS This was a randomized phase II/III study. Adult patients (age ≥ 18 years) with LAHNSCC planned for chemoradiation and an Eastern Cooperative Oncology Group performance status of 0-2 and who were cisplatin-ineligible were randomly assigned in 1:1 to either radiation alone or radiation with concurrent docetaxel 15 mg/m2 once weekly for a maximum of seven cycles. The primary end point was 2-year disease-free survival (DFS). RESULTS The study recruited 356 patients between July 2017 and May 2021. The 2-year DFS was 30.3% (95% CI, 23.6 to 37.4) versus 42% (95% CI, 34.6 to 49.2) in the RT and Docetaxel-RT arms, respectively (hazard ratio, 0.673; 95% CI, 0.521 to 0.868; P value = .002). The corresponding median overall survival (OS) was 15.3 months (95% CI, 13.1 to 22.0) and 25.5 months (95% CI, 17.6 to 32.5), respectively (log-rank P value = .035). The 2-year OS was 41.7% (95% CI, 34.1 to 49.1) versus 50.8% (95% CI, 43.1 to 58.1) in the RT and Docetaxel-RT arms, respectively (hazard ratio, 0.747; 95% CI, 0.569 to 0.980; P value = .035). There was a higher incidence of grade 3 or above mucositis (22.2% v 49.7%; P < .001), odynophagia (33.5% v 52.5%; P < .001), and dysphagia (33% v 49.7%; P = .002) with the addition of docetaxel. CONCLUSION The addition of docetaxel to radiation improved DFS and OS in cisplatin-ineligible patients with LAHNSCC.[Media: see text].

Prognostic Value of Radiological Extranodal Extension Detected by Computed Tomography for Predicting Outcomes in Patients With Locally Advanced Head and Neck Squamous Cell Cancer Treated With Radical Concurrent Chemoradiotherapy. Front Oncol 2022; 12:814895. [PMID: 35719994 PMCID: PMC9202501 DOI: 10.3389/fonc.2022.814895] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Accepted: 04/13/2022] [Indexed: 11/14/2022] Open
Abstract
Objective Extra Nodal Extension (ENE) assessment in locally advanced head and neck cancers (LAHNCC) treated with concurrent chemo radiotherapy (CCRT) is challenging and hence the American Joint Committee on Cancer (AJCC) N staging. We hypothesized that radiology-based ENE (rENE) may directly impact outcomes in LAHNSCC treated with radical CCRT. Materials and Methods Open-label, investigator-initiated, randomized controlled trial (RCT) (2012–2018), which included LAHNSCC planned for CCRT. Patients were randomized 1:1 to radical radiotherapy (66–70 grays) with concurrent weekly cisplatin (30 mg/m2) [cisplatin radiation arm (CRT)] or same schedule of CRT with weekly nimotuzumab (200 mg) [nimotuzumab plus CRT (NCRT)]. A total of 536 patients were accrued and 182 were excluded due to the non-availability of Digital Imaging and Communications in Medicine (DICOM) computed tomography (CT) data. A total of 354 patients were analyzed for rENE. Metastatic nodes were evaluated based on five criteria and further classified as rENE as positive/negative based on three-criteria capsule irregularity with fat stranding, fat invasion, and muscle/vessel invasion. We evaluated the association of rENE and disease-free survival (DFS), loco-regional recurrence-free survival (LRRFS), and overall survival (OS). Results A total of 244 (68.9%) patients had radiologically metastatic nodes (rN), out of which 140 (57.3%) had rENE. Distribution of rENE was balanced in the two study groups CRT or NCRT (p-value 0.412). The median follow-up period was 39 months (ranging from 35.5 to 42.8 months). Complete response (CR) was seen in 204 (57.6%); incomplete response (IR), i.e., partial response plus stable disease (PR + SD), in 126 (35.6%); and progressive disease (PD) in 24 (6.8%). rENE-positive group had poor survival compared to rENE-negative group 3-year OS (46.7% vs. 63.6%), poor DFS (48.8% vs. 87%), and LRRFS (39.9% vs. 60.4%). rENE positive had 1.71 times increased risk of IR than rENE negative. Overall stage, site, clinical metastatic node (cN), response, and rENE were the significant factors for predicting OS, DFS, and LRRFS on univariate analysis. After making adjustment on multivariate analysis, rENE was an independent prognostic factor for DFS and trending to be significant for OS. Conclusion Pre-treatment rENE is an independent prognostic marker for survival in patients with LAHNSCC treated radically with CCRT that can be used as a potential predictive marker for response to treatment and hence stratify patients into responders vs. non-responders. We propose the mahajan rENE grading system applicable on CT, magnetic resonance imaging, positron emission tomography–contrast-enhanced CT, and ultrasound.

Abstract
PURPOSE The objective of this study was to explore the potential role and safety of neoadjuvant chemotherapy (NACT) in tumor shrinkage and resultant mandibular preservation in oral cancers compared with conventional surgical treatment. METHODS This study was a single-center, randomized, phase II trial of treatment-naive histologically confirmed squamous cell carcinoma of the oral cavity with cT2-T4 and N0/N+, M0 (American Joint Committee on Cancer, seventh edition) stage, necessitating resection of the mandible for paramandibular disease in the absence of clinicoradiologic evidence of bone erosion. The patients were randomly assigned (1:1) to either upfront surgery (segmental resection) followed by adjuvant treatment (standard arm [SA]) or two cycles of NACT (docetaxel, cisplatin, and fluorouracil) at 3-week intervals (intervention arm [IA]), followed by surgery dictated by postchemotherapy disease extent. All patients in the IA received adjuvant chemoradiotherapy, and patients in the SA were treated as per final histopathology report. The primary end point was mandible preservation rate. The secondary end points were disease-free survival and treatment-related toxicity. RESULTS Sixty-eight patients were enrolled over 3 years and randomly assigned to either SA (34 patients) or IA (34 patients). The median follow-up was 3.6 years (interquartile range 0.95-7.05 years). Mandibular preservation was achieved in 16 of 34 patients (47% [95% CI, 31.49 to 63.24]) in the IA. The disease-free survival (P = .715, hazard ratio 0.911 [95% CI, 0.516 to 1.607]) and overall survival (P = .747, hazard ratio 0.899 [95% CI, 0.510 to 1.587]) were similar in both the arms. Complications were similar in both arms, but chemotherapy-induced toxicity was observed in the majority of patients (grade III: 14, 41.2%; grade IV: 11, 32.4%) in the IA. CONCLUSION NACT plays a potential role in mandibular preservation in oral cancers with acceptable toxicities and no compromise in survival. However, this needs to be validated in a larger phase III randomized trial.

Abstract
Direct laryngoscopy (DL) is the standard of care for the evaluation of suspicious lesions in the larynx and hypo pharynx but requires general anaesthesia and a dedicated operation theatre. While DL offers us the ability to map the lesion adequately and take a biopsy, it requires workup for anaesthesia well as rigid oesophagoscopy for assessing the oesophagus with its associated complications. Sixty-nine patients underwent TNE under topical anaesthesia. The lesions were mapped and biopsies taken. Those patients who had an inadequate evaluation on TNE or negative biopsy underwent direct laryngoscopy. Completeness of evaluation, adequacy of biopsy, presence of synchronous oesophageal lesions and the modified Gloucester Comfort Score for patient comfort was documented. Amongst 69 cases enrolled for TNE evaluation, 97% of cases had an adequate mapping of disease extent, and 100% adequacy of biopsy material. General anaesthesia could be avoided in 92.75% of patients. TNE took a median time of 8 min. Synchronous oesophageal tumours were seen in 5.8% of patients. There were no complications and 74% patients did not experience any discomfort. TNE appears to be simple, safe, efficient office based diagnostic procedure. TNE has the potential to be the new standard of care making DL obsolete.

Abstract
Aims This study aims to report on the demographic profile and treatment pattern of head and neck cancer patients and impact of an early treatment decision on treatment. This study also aims to suggest recommendations to improve treatment compliance. Methods All new patients registered under the head and neck disease management group (DMG) over a period of 3 months at a single center were included. Their demographic details, time to treatment decision, and treatment compliance were determined. The findings were presented to head and neck DMG, and changes were implemented to patient workup with an aim to improve compliance. A reaudit was performed over a period of 3 months and results were compared. Results Two thousand two hundred and forty patients were included in the analysis. Patients with a treatment decision at 1-4 weeks stood at 28.32%, 63.88%, 80.8%, and 89.87%, respectively. Dropout rate was 26%. About 50% of patients planned for surgical intervention could be treated within the institution. After implementation of changes as recommended by DMG, 2418 patients were analyzed and findings were compared to the previous audit. The dropout rate reduced to 17.57%. The number of patients with a treatment decision at 1-4 weeks were 51.26%, 77.42%, 89.46%, and 94.31%, respectively. Conclusion Early treatment decision and referral could significantly improve patient dropout and possibly compliance to treatment. Decentralization of cancer care is urgently needed to manage the high numbers of patients presenting to tertiary care centers. Setting up of new regional cancer centers and increasing infrastructure in the existing centers should be the long-term goals.

Abstract
Renal cell carcinoma (RCC) is the most common malignancy to cause metastasis to sinonasal cavity. These metastases can occasional cause invasion into the orbit. Isolated intraconal intraorbital metastasis from RCC is very rare. We hereby describe a case of 72-year-old female, who underwent right nephrectomy for RCC, 8 years back, and now presenting with a space occupying lesion in the right intraorbital intraconal compartment with no involvement of the paranasal sinuses. En bloc resection of the tumor was achieved via transnasal endoscopic approach. This is a rare case where minimally invasive surgery was done for metastatic lesion, with minimal postoperative morbidity.

Abstract
Among the reconstructive options available for buccal mucosa defects with an intact mandible, free flap with microvascular anastomosis is the best option. However, in the developing world, with poor resources, limited in- frastructure, and high patient load, this cannot be offered to all patients. We report on the success of the masseter flap for reconstruction of such defects in carefully selected patients. Despite some known limitations, this flap is easy to learn and carries acceptable complications. The results of this flap may not be comparable to those of microvas- cular reconstructions, but they are better than those from other options such as skin graft, nasolabial flap, submental flap, etc. in terms of surgical time required, no donor site morbidity, and minimal aesthetic deformity.

Abstract
The severe acute respiratory syndrome corona virus 2(SARS-Cov2) virus replicates in the nasal cavity, nasopharynx, and the oropharynx. During oral surgery, the risk of viral transmission is high during instrumentation in these areas, while performing airway management procedures, the oral surgery itself, and related procedures. During the corona virus disease 2019 (COVID-19) pandemic, patients with an oral pathology usually present for emergency procedures. However, patients with oral cancer, being a semi-emergency, may also present for diagnostic and therapeutic procedures. When elective surgeries are resumed, these patients will come to the operating room. In asymptomatic patients, the false-negative rate can be as high as 30%. These patients are a source of infection to the healthcare workers and other patients. This mandates universal precautions to be taken for all patients presenting for surgery. Lesions along the airway, distorted anatomy secondary to cancer therapy, shared airway with the surgeon, surgical handling of the airway and the risk of bleeding, make airway management challenging in these patients, especially while wearing personal protective equipment. Airway management procedures, oral surgery, use of cautery, and other powered surgical instruments in the aero digestive tract, along with constant suctioning are a source of significant aerosol generation, further adding to the risk of viral transmission. Maintaining patient safety, while protecting the healthcare workers from getting infected during oral surgery is paramount. Meticulous advance planning and team preparation are essential. In this review, we discuss the challenges and recommendations for safe anesthesia practice for oral surgery during the COVID-19 pandemic, with special emphasis on risk mitigation.

Abstract
Sinonasal tumours are rare, and among these there exist a small number of histologic subtypes that are infrequently encountered and rarely mentioned in the literature. These have been presented as either case reports or small case series, and their very low incidence makes prospective studies practically impossible. This review analyses the available literature, including our own experience and endeavours to outline management strategies, which involve a high index of suspicion and counselling of patients. In most instances, these tumours require aggressive multimodal treatment to improve survival outcomes. The overall prognosis remains dismal.

Abstract
BACKGROUND Studies reporting outcomes of salvage surgery in locally advanced head and neck squamous cell carcinoma (LAHNSCC) have inherent biases like biological and temporal selection. Our study considered all patients deemed fit for salvage surgery and compared to those who underwent surgery versus those who refused it thus throwing light on the real world benefit of salvage surgery. METHODS This was a post hoc analysis of a phase 3 randomized trial conducted between 2012 and 2018. Out of 536 LAHNSCC patients randomised in the study, 113 patients had residual disease or recurrent disease and were planned for salvage surgery in a multidisciplinary clinic. Patients were divided into 2 cohorts for comparison, willing for salvage surgery (n = 91) and unwilling for salvage surgery(n = 22). The primary endpoint was overall survival. RESULTS The median follow up was 28.7 months (95%CI 23.9-33.5 months). Out of the 91 patients who were willing for salvage surgery, 78 underwent same. The median survival in cohort of patients willing for salvage surgery was 22.0 months (95%CI 10.1-33.9) while it was 9.7 months (95%CI 6.6-12.8) in patients who were unwilling for salvage surgery (HR = 0.262 95%CI HR 0.147-0.469, p = 0.000). CONCLUSION Salvage surgery leads to a substantial improvement in outcomes in head and neck cancers and should be the de facto standard of care in patients who are eligible for the same.

Abstract
Oncological surgery being radical is often mutilating in form and function especially in the maxillary/orbit region reconstruction of maxillo-orbit defects are challenging due to the complex three dimensional anatomy. Free flaps are de-rigueur but a technical resource with constraints. The temporalis myofascial flap (TMFF) is a locally available, safe and reliable flap which can be used for the reconstruction of various orbital and supramaxillary facial defects. To study the use of the temporalis myofascial flap in the reconstruction of various orbital and supramaxillary facial defects. Temporalis myofascial flap was harvested and successfully used in reconstruction of three patients who had undergone orbital exenteration with or without suprastructural maxillectomy. There was no morbidity related to flap loss. Temporalis flap (TMFF) can be considered as a first line reconstructive option for limited resection of upper maxilla with palatal preservation. Its proximity to the oral cavity, palate and mid third face and the technical ease makes the TMFF valuable for reconstruction. The techniques and outcomes of TMFF are discussed.

A randomized phase 3 trial comparing nimotuzumab plus cisplatin chemoradiotherapy versus cisplatin chemoradiotherapy alone in locally advanced head and neck cancer. Cancer 2019; 125:3184-3197. [PMID: 31150120 DOI: 10.1002/cncr.32179] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2019] [Revised: 03/02/2019] [Accepted: 03/22/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND Because the addition of nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings. METHODS This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m2 ) (CRT) or the same schedule of CRT with weekly nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed. RESULTS In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01). CONCLUSIONS The addition of nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m2 cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.

Abstract
Objective Total thyroidectomy with or without central compartment dissection is the treatment of choice for thyroid carcinoma. Extensive dissection along the recurrent laryngeal nerve (RLN) can lead to vocal cord fixity and hoarseness even without nerve sacrifice. Recovery rates after surgery for thyroid cancers have not been well documented. The aim of the study is to analyze the incidence of vocal cord palsy (VCP) and its recovery rates in patients operated for thyroid cancers. Methodology: We performed a retrospective study on prospectively collected data in 152 thyroidectomy patients with 254 RLNs at risk. All patients underwent a laryngoscopic examination to document vocal cord function in the immediate postoperative period and on subsequent follow-up. Incidence of VCP, recovery rates, univariate and multivariate analysis to identify risk factors for permanent VCP were calculated using binary logistic regression. Results In our study, 28% patients underwent redo surgeries and 74% patients had dissection of the central compartment. The immediate postoperative RLN palsy rate was 11.2%, with a palsy rate of 9% and 16.2% in the per primum and redo surgery cohorts. On follow-up, there was complete recovery of VCP in 66.7% of these nerves. The incidence of permanent RLN palsy was 3.9%. The mean time to recovery was 9.6 months. Conclusion Vocal cord dysfunction recovered in most patients in this high-risk cohort. There was a significant recovery even in the redo surgery group and a policy of watchful waiting is recommended in the absence of severe symptoms. Level of Evidence III.

Abstract
Purpose Chemoradiation with cisplatin 100 mg/m2 given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m2 given once a week compared with cisplatin 100 mg/m2 given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC. The primary end point was locoregional control (LRC); secondary end points included toxicity, compliance, response, progression-free survival, and overall survival. Results Between 2013 and 2017, we randomly assigned 300 patients, 150 to each arm. Two hundred seventy-nine patients (93%) received chemoradiotherapy in the adjuvant setting. At a median follow-up of 22 months, the estimated cumulative 2-year LRC rate was 58.5% in the once-a-week arm and 73.1% in the once-every-3-weeks arm, leading to an absolute difference of 14.6% (95% CI, 5.7% to 23.5%); P = .014; hazard ratio (HR), 1.76 (95% CI, 1.11 to 2.79). Acute toxicities of grade 3 or higher occurred in 71.6% of patients in the once-a-week arm and in 84.6% of patients in the once-every-3-weeks arm ( P = .006). Estimated median progression-free survival in the once-a-week arm was 17.7 months (95% CI, 0.42 to 35.05 months) and in the once-every-3-weeks arm, 28.6 months (95% CI, 15.90 to 41.30 months); HR, 1.24 (95% CI, 0.89 to 1.73); P = .21. Estimated median overall survival in the once-a-week arm was 39.5 months and was not reached in the once-every-3-weeks arm (HR, 1.14 [95% CI, 0.79 to 1.65]; P = .48). Conclusion Once-every-3-weeks cisplatin at 100 mg/m2 resulted in superior LRC, albeit with more toxicity, than did once-a-week cisplatin at 30 mg/m2, and should remain the preferred chemoradiotherapy regimen for LAHNSCC in the adjuvant setting.

Abstract
Expression of cancer-associated biomarkers represents a great potential for a more precise diagnosis for patient stratification and more personalized treatment of oral squamous cell carcinoma (OSCC). The aim of this study was to develop an immunohistochemistry-based malignancy index diagnostic system (IHC-MIDS) based on the expression of a panel of several molecules expressed by different tumor components and involved in different oncogenic pathways. IHC was performed on paraffin embedded formalin fixed tissue samples from 102 patients for the following biomarkers: p16, p53, ki67, p75NTR, LoxL4, aSMA, Foxp3, CD68, CD 163, CD80, FVIII and D2-40. The stained tissues were scanned and quantified using Immage J open source software. An IHC-MIDS score was developed using correlation-based feature selection algorithm. IHC-MIDS was able to stratify OSCC lesions for several clinical pathological features, including the risk of recurrence. This study shows that a scoring system based on expression of a panel of biomarkers is more precise than the use of a single biomarker and that it can be used for risk stratification of OSCC lesions in order to guide further management.

Abstract
Phosphaturic mesenchymal tumor (PMT) is a rare mesenchymal neoplasm associated with tumor-induced osteomalacia (TIO) and elevated serum FGF-23. Common in extremities, PMT rarely occurs in sinonasal region. We report a series of sinonasal PMT diagnosed at our institute over a 6-year period. Six cases of sinonasal PMT were identified during this period, of which five presented with features of TIO. Median age of patients was 45.5 years. All six tumors were composed of stellate to spindled cells, with prominent staghorn vasculature in four cases. Typical smudgy matrix was seen in all cases, but only focally; grungy calcification was absent. Accurate diagnosis of PMTs is imperative, as complete excision leads to dramatic resolution of TIO symptoms. Lack of knowledge of this entity prevents clinicians from ordering relevant investigations. Absence of specific morphological features, like grungy calcification, and presentation at atypical locations makes the diagnosis challenging. Awareness of this entity is essential in order to suspect PMT in patients presenting with a soft tissue mass and features of TIO, however unusual the location may be.

Abstract
BACKGROUND Cisplatin and 5 fluorouracil drug combination is inferior to the combination of taxane with these 2 drugs. However, often in clinical practice at our center giving TPF (docetaxel, cisplatin, 5 fluorouracil) is difficult in view of logistics and tolerance issues. In such a scenario, we prefer to use the 2 drugs combination of platinum and taxane. However, no study has addressed whether a 2 drugs combination, which includes taxane is inferior to the 3 drugs combination and which the taxane of choice is in the 2 drugs combination of taxane and platinum. METHODS This is a retrospective analysis of prospectively collected data of patients undergoing induction chemotherapy (IC) in oral cavity cancers from 2010 to 2012. We chose for analysis those patients who had a baseline scan done within 4 weeks of starting therapy and a follow-up scan done within 2 weeks of completion of the second cycle of IC. Response was scored in accordance with RECIST version 1.1. Chi-square analysis was done to compare response rates (RRs) between regimens. RESULTS Two hundred and forty-five patients were identified. The median age was 45 years (24-70 years), 208 (84.9%) were male patients, and 154 patients (62.9%) had primary in the Buccal mucosa. The regimens received were TPF 22 (9%), docetaxel + cisplatin 97 (39.6%), paclitaxel + cisplatin 89 (36.3%), docetaxel + carboplatin 16 (6.5%) and paclitaxel + carboplatin 21 (8.6%). The overall RRs were complete response, partial response, stable disease and progressive disease in 4 (1.6%), 56 (22.9%), 145 (59.2%) and 40 (16.3%). The 3 drugs regimen (TPF) had 50% RR as compared to 22% RR with 2 drugs regimen (P = 0.004). Docetaxel containing regimens had 30.3% RR as compared to 17.2% RR with paclitaxel containing regimens (P = 0.094). CONCLUSIONS TPF has better RR than a 2 drugs taxane-containing regimen and docetaxel leads to a better RR than paclitaxel for IC in locally advanced oral cavity cancers.

Abstract
Head and neck cancers (HNCs) are the most common malignancies worldwide. Asian populations bear major burden of this disease, with certain unique characteristics. Although significant research in HNCs is ongoing globally, many clinical issues still remain unanswered. We performed a literature search to find noteworthy Indian studies that changed practice of HNC as well as to look for areas for further research in this field. Many randomized controlled trials as well as large patient series are reported in the field of radiotherapy, chemotherapy, and surgical management of HNC. Still, many areas such as palliative therapy, targeted agents, and newer chemotherapeutic agents remain unexplored. Planned collaborative research is need of the hour to provide more evidenced based.

Abstract
Malignant melanomas involving the mucosa are rare and aggressive lesions. Their rarity has made the formulation of staging and treatment protocols very difficult, as most of the available information comes from case reports and small case series. We conducted a retrospective study to analyze the behavior of melanomas of the oral mucosa in patients who were treated at Tata Memorial Hospital in Mumbai, a tertiary care referral center for malignancies and one of the largest cancer centers on the Indian subcontinent. During the 22-year period from January 1986 through December 2007, we found only 13 such cases, which had occurred in 8 men and 5 women, aged 26 to 70 years (mean: 37.5). All patients had been offered surgery with curative intent. Mucosal melanomas have exhibited a greater tendency for distant recurrence than for local treatment failure, which is why adjuvant radiation therapy has not been shown to confer any consistent benefit. In our study, only 3 of the 13 patients (23.1%) remained alive 2 years after diagnosis, despite aggressive treatment. Tumor staging, optimal treatment, and prognostic factors for oral mucosal melanoma are far from clear, and further research is needed. Despite the small number of patients in this study, it still represents one of the largest series of oral mucosal melanoma patients in India.

Abstract
BACKGROUND Positron emission tomography-computed tomography (PET-CT) is an emerging modality for staging and response evaluation in carcinoma nasopharynx. This study was conducted to evaluate the impact of PET-CT in assessing response and outcomes in carcinoma nasopharynx. MATERIALS AND METHODS Forty-five patients of nonmetastatic carcinoma nasopharynx who underwent PET-CT for response evaluation at 10-12 weeks posttherapy between 2004 and 2009 were evaluated. Patients were classified as responders (Group A) if there was a complete response on PET-CT or as nonresponders (Group B) if there was any uptake above the background activity. Data regarding demographics, treatment, and outcomes were collected from their records and compared across the Groups A and B. RESULTS The median age was 41 years. 42 out of 45 (93.3%) patients had WHO Grade 2B disease (undifferentiated squamous carcinoma). 24.4%, 31.1%, 15.6, and 28.8% patients were in American Joint Committee on Cancer Stage IIb, III, Iva, and IVb. All patients were treated with neoadjuvant chemotherapy followed by concomitant chemoradiotherapy. Forty-five patients, 28 (62.2%) were classified as responders, whereas 17 (37.8%) were classified as nonresponders. There was no significant difference in the age, sex, WHO grade, and stage distribution between the groups. Compliance to treatment was comparable across both groups. The median follow-up was 25.3 months (759 days). The disease-free survival (DFS) of the group was 57.3% at 3 years. The DFS at 3 years was 87.3% and 19.7% for Group A and B, respectively (log-rank test, P < 0.001). Univariate and multivariate analysis revealed Groups to be the only significant factor predicting DFS (P value 0.002 and < 0.001, respectively). In Group B, the most common site of disease failure was distant (9, 53%). CONCLUSION PET-CT can be used to evaluate response and as a tool to identify patients at higher risk of distant failure. Further, this could be exploited to identify patients who may need treatment intensification. This needs to be validated prospectively.

Abstract
Papillary carcinomas are the most common thyroid malignancy accounting for approximately 80 % of thyroid cancers (Rosenbaum and McHenry Expert Rev Anticancer Ther 9:317-329, 2009). They generally manifest as solitary nodules in the thyroid with or without cervical lymphadenopathy. Distant metastases though rare, are commonly seen in lungs and bones, other rare sites are parotid, skin, brain, ovary, adrenal, kidney, Pancreas and breast. We herein present an unusual case of breast lump as an initial presentation of a well differentiated thyroid cancer in a male patient. Our case is unique since it presented with isolated breast metastasis in a male patient in the absence of primary diagnosis. This prompted us to report the case with review of literature. A brief review of literature follows.

Abstract
Among the reconstructive options available for buccal mucosa defects with an intact mandible, free flap with microvascular anastomosis is the best option. However, in the developing world, with poor resources, limited infrastructure, and high patient load, this cannot be offered to all patients. We report on the success of the masseter flap for reconstruction of such defects in carefully selected patients. Despite some known limitations, this flap is easy to learn and carries acceptable complications. The results of this flap may not be comparable to those of microvascular reconstructions, but they are better than those from other options such as skin graft, nasolabial flap, submental flap, etc., in terms of surgical time required, no donor site morbidity, and minimal aesthetic deformity.

Abstract
BACKGROUND Use of any treatment modality in cancer depends not only on the effectiveness of the modality, but also on other factors such as local expertise, tolerance of the modality, cost and prevalence of the disease. Oropharyngeal and laryngeal cancer are the major subsites in which majority of neoadjuvant chemotherapy (NACT) literature in the head and neck cancers is available. However, oral cancers form a major subsite in India. MATERIALS AND METHODS This is an analysis of a prospectively maintained data on NACT in the head and neck cancers from 2008 to 2012. All these patients were referred for NACT for various indications from a multidisciplinary clinic. Descriptive analysis of indications for NACT in this data base is presented. RESULTS A total of 862 patients received NACT within the stipulated time period. The sites where oral cavity 721 patients (83.6%), maxilla 41 patients (4.8%), larynx 33 patients (3.8%), laryngopharynx 8 patients (0.9%) and hypopharynx 59 patients (8.2%). Out of oral cancers, the major indication for NACT was to make the cancer resectable in all (100%) patients. The indication in carcinoma of maxilla was to make the disease resectable in 29 patients (70.7% of maxillary cancers) and in 12 patients (29.3% of maxillary cancers) it was given as an attempt to preserve the eyeball. The indication for NACT in laryngeal cancers was organ preservation in 14 patients (42.4% of larnyngeal cancer) and to achieve resectability in 19 patients (57.6% of larnyngeal cancer). The group with laryngopharynx is a cohort of eight patients in whom NACT was given to prevent tracheostomy, these patients had presented with early stridor (common terminology criteria for adverse events Version 4.02). The reason for NACT in hypopharyngeal cancers was for organ preservation in 24 patients (40.7% of hypopharyngeal cancer) and for achievement of resectability in 35 patients (59.3% of hypopharyngeal cancer). CONCLUSION The major indication for NACT is to make disease resectable at our center while cases for organ preservation are few.

Abstract
BACKGROUND Determining the level of nodal metastases may help decrease the extent of neck dissections and reduce morbidity. METHODS A prospective study of neck dissections in patients with oral cancer was conducted. Each nodal level was delineated, sent for histopathology, and reported level-wise. Incidence of overall and isolated metastatic nodes at different levels was calculated. Logistic regression was used to find factors predicting metastases to levels IIB and V. RESULTS Five hundred eighty-three neck dissections were prospectively evaluated. A total of 95.7% metastases occurred at levels I to IV. Overall incidence of metastases to levels IIB and V was 3.8% and 3.3%, respectively. Multivariate analysis revealed IIA positivity as an independent predictive factor for metastases to both IIB and V. CONCLUSION This study of lymph node mapping in patients with oral cancer showed a predictable pattern of lymph node metastasis according to primary site. Selective neck dissection (levels I-IV) in patients with oral cancers may be adequate. Determining status of level IIA is important to guide dissection of levels IIB and V.

Abstract
OBJECTIVE The surgical treatment of cancer of tongue results in speech deficits. Speech disorders in the glossectomised patients fall into, categories of impaired articulation, reduced speech intelligibility, altered oral & nasal resonance, impaired voice quality & reductions in global speech proficiency. Since speech is a social tool, its most significant measurements start with the degree to which it can be understood. METHODS This study was conducted at Tata Memorial Hospital, Mumbai, India, An incidental sample of 25 patients was selected for this study. Different questionnaires specially devised for this study were used to assess patients' speech & deglutition post-operatively. The data was collected 3 months after surgery of these patients. RESULTS Studies have indicated that larger the segment of the tongue, the greater is the distortion of speech & difficulty in deglutition. All functions associated with the interaction of the tongue with the related anatomy of the head & neck were severely impaired following glossectomy. The rehabilitation plan for partial glossectomy patients depended upon the assessment of their post-operative articulation level, education, job, age, family & motivation.

Abstract
AIM This retrospective study was done to evaluate the impact of cut margins on disease-free survival in patients with previously untreated oral squamous cell cancers. MATERIALS AND METHODS Records of 306 cases were reviewed for clinical details and status of margins at resection. The independent influence of margins on recurrence was analyzed. The impact of frozen section analysis on achieving free margins was also examined. RESULTS 190 (62.1%) patients had negative margins of resection (≥ 5 mm), 102 (33.3%) patients had close margins (1-5 mm), while 14 (4.6%) patients had positive margins (≤ 1 mm). The median follow-up for the entire cohort was 26.5 months. There were 79 (25.8%) recurrences, of which, 46 (58.2%) were local, 9 (11.3%) were locoregional, 16 (20.2%) were regional, and 8 (10.1%) were distant metastasis. 42 (22.2%) cases with negative margins developed a recurrence as compared to 31 (30.4%) cases with close margins and 6 (42.8%) cases with positive margins (P value 0.01). Average time to recurrence in case of negative margins was 34.8 months, for close margins was 33.9 months, while in those with positive margins was 10.18 months (P value 0.002). Close and positive margins were found to be significantly associated with increased local recurrence (P values 0.01 and 0.03, respectively) and with overall recurrence (P values 0.003 and 0.003, respectively). Frozen section was seen to influence margins in 20.4% cases. CONCLUSION Margins are an important predictor of disease control. The surgeon must aim for adequate margins at initial resection.

Abstract
Polymorphisms in metabolic and DNA repair genes may alter protein function, consequently affecting patients' response to chemo/radiotherapy. We retrospectively assessed whether polymorphisms of glutathione-S-transferase genes GSTM1 (deletion), GSTT1 (deletion), GSTP1 (Ile105Val, rs1695), and DNA repair genes hOGG1 (Ser326Cys, rs1052133), XRCC1 (Arg194Trp, rs1799782, and Arg399Gln, rs25487), XPD (Asp312Asn, rs1799793, and Lys751Gln, rs13181) can predict clinical outcome in 187 oral squamous cell carcinoma patients treated with postoperative radiotherapy. The Cox proportional hazards model was used to evaluate the role of polymorphic genotypes on relapse-free (RFS) and disease-specific (DSS) survival. Deletion polymorphism of GSTM1 gene was significantly associated with DSS. The rs1799793 variant allele showed significant protection in both DSS and RFS. Significant increase in RFS but not in DSS was observed with polymorphic rs13181. The combined analysis of GSTM1 and XPD polymorphisms revealed favorable effect on survival. GSTM1 and XPD variant alleles, independently as well as in combination may serve as important predictors of clinical outcome in radiotherapy-treated OSCC patients.

Abstract
We report an unusual case of epidermal inclusion cyst of the styloid process which presented to us with decreased hearing and tinnitus. The patient underwent complete excision via a combined postaural cervical approach. The unusual location of the tumor and the absence of a history of trauma or intervention in that area added confusion to the diagnosis, which was finally made on histopathology.

Abstract
BACKGROUND The aim of this study is to determine the need for a randomized controlled trial in order to define the role of an elective neck dissection (END) in the treatment of early tongue cancers. METHODS We present a large retrospective analysis of patients with T1-2 N0 squamous cell cancers of the oral anterior tongue treated at a single institution. A total of 359 eligible patients with early tongue cancers were divided into 2 groups: END and wait and watch (WW). An analysis for survival outcomes and prognostic factors was conducted. RESULTS The estimated 3- and 5-year disease-free survival for the END group was 76% and 74% versus 71% and 68% for the WW group, respectively (p = .53). The 3- and 5-year overall survival (OS) rate for the END group was 69% and 60% versus 62% and 60% for the WW group, respectively (p = .24). Tumor grade and perineural invasion were independent predictors of recurrence. CONCLUSION END did not impact disease-free or OS. Current literature still remains divided on this issue emphasizing the need for a randomized controlled trial.

Abstract
PURPOSE Head and neck cancer (HNC) survivors have substantial psychological distress in addition to treatment-related side effects. This study examines the long-term quality of life (QOL) of HNC survivors in a busy tertiary care center. MATERIAL AND METHODS A prospective, cross-sectional survey was conducted studying 212 HNC survivors 1 year after completion of their treatment at a tertiary cancer center. Quality of life assessments were performed using the 2 standardized health-related QOL questionnaires: The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 and The Quality of Life Questionnaire Head and Neck Cancer Module. RESULTS The overall global QOL rating for the study cohort was satisfactory. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 scores showed that the domains where most patients faired poorly included financial difficulties (54%), appetite loss (36%), fatigue (33%), and cough (30%). The Quality of Life Questionnaire Head and Neck Cancer Module scale identified the domains with poor scores to be dry mouth (64%), dental problems (42%), sticky saliva (40%), cough (39%), and problems with mouth opening (32%). Patients with early-stage tumors and those treated with surgery alone had significantly better QOL scores when compared with advanced stage tumors and patients receiving either radiation alone or multimodality treatment, respectively. CONCLUSIONS Quality of life questionnaires provide a medium for patients to effectively communicate with their physician in a busy tertiary care facility and provide an insight into the physical, psychological, and social problems affecting our patients which can then direct future interventions.

Abstract
The purpose of our study was to analyze the indicators of loco-regional failure in a large cohort of patients with gingivobuccal complex tumors treated at a single institution. A retrospective review of 2275 patients diagnosed with tumors of the gingivobuccal complex was conducted from January 1997 to December 1999; 642 patients who fulfilled our inclusion criteria were analyzed. A univariate analysis, multivariate analysis, and disease-free survival are reported. During a median follow up of 2.51 years, there were 228 (35.5%) recurrences with a median post-recurrence survival of 2.7 months. The incidence of occult neck metastasis was 29%. The 2- and 5-year DFS rates were 63.8% and 53.3%, respectively. On multivariate analysis, tumor depth and metastatic lymphadenopathy were found to be independent prognostic factors for disease-free survival. Advanced gingivobuccal cancers fail loco-regionally. Cervical metastasis and tumor depth influence disease-free survival. Elective neck dissection due to a high incidence of occult neck disease is recommended.

Abstract
Squamous cell carcinoma of the superior gingival-buccal complex are rare and few English-language data have been published on their biological behaviour. Reported in this paper are the clinical behaviour and treatment outcomes of squamous cell carcinoma of the upper gingival-buccal complex. We reviewed the charts of 110 patients with squamous cell carcinoma restricted to the upper gingiva, superior gingival-buccal sulcus and adjoining buccal mucosa, seen between 1997 and 2001. Separate outcome analyses were carried out among 86 patients who had undergone surgery, and 24 patients treated by radiotherapy or chemo-radiation. Disease-free survival at 2 and 5 years was 48.9% and 36%, respectively, and was independent of epicentre of disease. Five-year, disease-free survival was 48.8% and 0% for surgical treatment and non-surgical treatment groups. T stage (p=0.024) and extra-capsular spread of disease (p=0.036) were independent predictors of disease-free survival on multivariate analysis. Adequate surgical resection and adjuvant treatment, in the first instance, offers the best chance of disease control.

Abstract
Selective neck dissection (I-III) for oral cancers offers similar regional control rates with less morbidity as compared with modified radical neck dissection. Charts of 414 patients with oral cancer, who underwent selective neck dissection (I-III) during 1994-2001, were analysed retrospectively. Seventy nine percent of the patients had a primary tumour in the gingivo-buccal complex. Cancer of tongue showed a trend towards higher regional failure (12.3%) as compared to gingivo-buccal cancers (6.5%). Primary tumour was staged as T1-8%, T2-47%, T3-19% and T4-26%. Sixty five percent of the patients were clinically node negative. Isolated neck failure was observed in 4.8% of patients at 2 years and in 5.8% at 5 years. De-differentiation of primary tumour and perineural spread were associated with regional failures. Eighty three percent of the neck recurrences were in the ipsilateral neck and only 16% of these were at levels IV or V. In all, 30% of all regional failures were outside the field of dissection.

Abstract
The pectoralis major myocutaneous (PMMC) flap is commonly used for head and neck reconstruction especially in impoverished nations. PMMC is a sturdy pedicled flap with relatively fewer complications, the learning curve is short and no specialized training in microvascular surgery is needed in order to use this flap. In a defect that requires a large skin and mucosal lining the authors routinely use either a bi-paddle PMMC or a combination of PMMC (for the mucosal lining) and a delto-pectoral flap (for the skin defect). It is indisputable that free tissue transfer is a better way of reconstruction for the majority of most such defects. Unfortunately, not all patients can be offered this form of reconstruction due to the cost, time, expertise and infrastructural constraints in high volume centres such as ours. Bi-paddling of PMMC is hazardous in obese males and most female patients. In such patients the skin defect is reconstructed usually by the delto-pectoral (DP) flap but this, for obvious reasons, is less welcomed by the patients. The authors suggest a technique wherein mucosal lining is created by the myofascial lining (inner surface) of the flap and the skin defect is reconstructed by the skin paddle of the single paddle PMMC. It should be considered wherever a DP flap is unacceptable, or bi-paddling or free tissue transfer is not possible.
