Glottic Stenosis.

Glottic stenosis may be congenital, such as anterior glottic webs, or acquired, as a result of surgery or prolonged intubation. Glottic-level obstruction may occur as an isolated lesion or as part of multilevel airway stenosis. Careful evaluation is required to distinguish neural causes of impaired vocal fold motion from true mechanical fixation, as the underlying etiology can influences surgical decision-making. When addressing glottic-level stenosis, particular attention must be paid to the potential effects on voice and swallowing while striving to achieve adequate airway caliber.
