title: Risk factors for dysphagia after transoral videolaryngoscopic surgery for laryngeal and pharyngeal cancer.
abstract: BACKGROUND
  Transoral surgery is gaining attention as a minimally invasive treatment option for laryngeal and pharyngeal cancer. Postoperative swallowing function is satisfactory in most cases, but occasionally dysphagia persists.
  
  
  METHODS
  Swallowing function of 86 patients who underwent transoral videolaryngoscopic surgery (TOVS) for laryngeal and pharyngeal cancers was evaluated by the Functional Outcome Swallowing Scale (FOSS) and risk factors for dysphagia were identified.
  
  
  RESULTS
  FOSS stage was 0 to 1 in 90%, 2 in 5.8%, 3 in 3.5%, and 4 in 1.2% of the patients. Only 1 patient had indication for percutaneous endoscopic gastrostomy (PEG). Univariate analysis revealed that resection of the pyriform sinus (p = .0280) and arytenoid (p = .0139), pulmonary dysfunction (p = .0353), and large mucosal defect (p = .0223) were associated with postoperative dysphagia.
  
  
  CONCLUSIONS
  Although the rate of PEG dependency is low in transoral surgery, surgeons should mention the risk of postoperative dysphagia when counseling patients preoperatively.
