Morbidity and Mortality Following Transoral Robotic Surgery, a Prospective Single Centre Study

To review complications including mortality after transoral robotic surgery (TORS) for both benign and malignant pathologies. This is a prospective observational study. Postoperative haemorrhage (8.7%) was the most common complication and 2 (1.7%) mortality were seen in this study. Airway complications and tracheostomy (1.7%), aspiration pneumonia (1.7%), swallowing problems and nasogastric feeding (7%), intra-operative pharyngocutaneous fistula (0.9%) and transient nasal regurgitation (3.5%) were also seen. The more tissue is removed the more is the risk of complication. Complications were mainly seen in the first year of starting the service of TORS and it is a reflection of the learning curve. However, secondary haemorrhage did not follow any pattern in our series. The postoperative haemorrhage was more common in patients with T2 oropharyngeal carcinoma. The mortality was seen in 2 patients (1.7%) with T2 oropharyngeal carcinoma due to postoperative haemorrhage. Higher T stage of oropharyngeal squamous cell carcinoma (OPSCC) needs bigger resection with resultant increase in morbidity.
