difference in disease specific or overall survival was found between the groups.

Conclusion Patients undergoing SLNB as the initial neck staging modality in early OSCC, and identified as pN+ve, do not appear to be at a survival disadvantage compared with those staged with ELND.

Purpose or Objective The resection of central arch of mandible poses a great challenge for reconstructive surgery. This study aims to compare various reconstructive options, either pedicled or free tissue transfer, used in our institution in terms of aesthetic and functional outcomes. Materials and Methods This retrospective series comprises of 28 patients of oral cavity cancer involving central arch, operated by extensive oro- mandibular resections and reconstruction between July 2016 to july 2020. The records were kept of total operation time and number of preoperative blood transfusions. Observations were made in the ICU and postoperative wards of any morbidity and the number of hospital days. The follow up of patients were done till the date of recurrence of disease. Results Out of 28 patients, 10 were women and 18 were men. In all patients, tumor type was squamous cell carcinoma and stage was T4. Regional flaps ( n =8) were used in patients with mean operative time of 337±32.6 minutes and mean postoperative stay of 6.7 days. Comparatively the mean operative time were 703 ± 53.3, 768±40.6, 540±21.2 minutes in various free flaps and mean postoperative stay in hospital was around 9 days. Complications occurred in 5 of 28 patients (18%), and there were no perioperative mortalities. During the follow up period, 8 patients died of recurrent cancer. Conclusion Single paddle free fibula flap fulfils requirements of most cases but in some cases with much larger defects and bulk of soft tissue required, application of two simultaneous free flap can be considered without adding morbidity to patients and provide better outcomes. Use of pedicled flaps cannot be ruled out in resource constrained set up and comorbid patients
