title: Glottal insufficiency with aspiration risk in dysphagia.
abstract: Glottal closure is an important part of the mechanism that protects the airway during the normal swallow. Glottal insufficiency disrupts glottal closure and therefore puts patients at risk of aspiration. Treatment of glottal insufficiency can be classified as surgical or nonsurgical. The objective of treating glottal insufficiency is to avoid aspiration or penetration of secretions or food into the airway. Nonsurgical treatment consists of swallowing maneuvers and other measures. Surgical treatment of glottal insufficiency includes injection laryngoplasty, medialization thyroplasty with or without arytenoid adduction or with arytenopexy and cricothyroid subluxation, hypopharyngoplasty, cricopharynx muscle dilation, and cricopharynx myotomy.
