The aim of this prospective study was to evaluate the mortality at one year follow-up of patients having early tumors of oropharynx undergoing Transoral Robotic Surgery. Material & methods: This prospective study was conducted in patients of T1 & T2 tumours of the oropharynx  who were treated by Transoral robotic Surgery between the period August 2016 to October 2018 at the Department of Otolaryngology and Head and Neck surgery, PGIMER, Chandigarh. During this period 42 patients were operated by TORS. All the patients   were asked to follow up once in 2 months up to a period of 1 year and mortality rate was noticed. Results: The mean age of patients enrolled in the study was 53.17 ± 11.491years, range being 28 - 70 years there were 38 males (90.5%) and 4 females (9.5%) in the study with a male to ratio of 9.5:1.  Mortality was found in two patients at one year follow up. In the present study,2 patients with tonsillar malignancy expired at one year follow up. In both the patients post operative deep surgical resection margins were involved. Both the patients had received post operative radiotherapy in view of positive deep resection margins on histopathological report. There was no mortality   in any patients of Salvage group and two patients died in the group in which surgery was done as Upfront/Primary modality. In both, the patients’ resection margins were positive. Mortality in patients with positive surgical margins on histopathological examination was significantly more compared to those with free surgical margins.  Mortality in patients with involved deep resection margins was found to be significantly more than those in whom the deep margins were not involved. Mortality was seen in two 2 patients who received adjuvant radiotherapy for deep resection margins involvement. There was no mortality in HPV positive   patients   at 1 year follow up. Conclusion: TORS affords potential advantages and benefits over current treatment modalities.
