Transoral endoscopic head and neck surgery is a new approach for the treatment of oropharyngeal tumors. Using either a robotic system and/or laser, surgeons gain access through the mouth via minimally invasive technique and thus have improved visualization of the tumors of the oropharynx, without disfiguring incisions. This transoral route of access minimizes long-term speech and swallowing dysfunction. Surgeons view this approach as a considerable technologic advance, analogous to the evolution in radiation therapy from conventional two- and three-dimensional conformal techniques to intensity-modulated techniques...

There is increasing evidence that intraoperative fluid therapy decisions may influence postoperative outcomes. In the past, patients undergoing major surgery were often administered large volumes of crystalloid, based on a presumption of preoperative dehydration and nebulous intraoperative 'third space' fluid loss. However, positive perioperative fluid balance, with postoperative fluid-based weight gain, is associated with increased major morbidity. The concept of 'third space' fluid loss has been emphatically refuted, and preoperative dehydration has been almost eliminated by reduced fasting times and use of oral fluids up to 2 h before operation...
