A prospective evaluation of postoperative swallowing function and dysphagia following endoscopic laryngopharyngeal surgery.

This necessitates additional care during the treatment of patients with mucosal defects ≥ 35 mm, owing to the significant association between the DRS and short-term swallowing function.
