TORS procedures offer many advantages to the alternative surgical techniques of open surgical resection and conventional endoscopic<unk> . The current literature indicates that the TORS technique results in less blood loss, shorter hospital stays, and lower complication rates than open<unk> . TORS as a cancer treatment To date, the largest study of TORS as a cancer treatment included data from 410 patients. This study demonstrated 91.8% 2-year locoregional control of the cancer, and 94.5% 2-year disease-specific survival. These numbers are similar to those of other head and neck cancer treatment options. A separate study of 62 patients found that 69% resumed oral intake prior to discharge, and 83% within two weeks. TORS/TORSA as an obstructive sleep apnea treatment The Apnea-Hypopnea Index (AHI), the number of breathing obstructions or near-obstructions per hour of sleep, is one common way to measure the degree of a patient's sleep apnea. The higher the number, the worse the breathing during sleep. In a 2016 study of 75 patients, the average decrease in AHI post-TORS was 45%. Another 2016 study found an average AHI reduction of 51% in 11 patients. Researchers have also investigated the effect of TORS<unk>  for obstructive sleep apnea on swallowing function. A 2015 study of 78 patients found that oral feeding was resumed on average 1.05 days post-operatively, and not a single patient complained of long-term swallowing difficulty. Complications Many studies have evaluated TORS patient outcomes and have found complications in 10-25% of cases. Most of these are minor, including dehydration, tooth injury, bleeding, dysphagia, dysgeusia, and uncontrolled pain. Fewer patients develop major complications, which include hemorrhage, deep venous thrombosis, pneumonia, pulmonary embolism, or death.
