Application of mitomycin C after endoscopic lysis of congenital laryngeal web combined with epiglottic hypoplasia in a middle-aged man.
Laryngeal webs and epiglottic hypoplasias are uncommon congenital anomalies. Anterior glottic web combined with epiglottic hypoplasia was found in a middle-aged man presenting with hoarseness and dyspnea on exertion. This can be considered as a unique isolated defect of the larynx during early fetal development. The laryngeal web can be successfully treated in a single stage with endoscopic lysis and topical application of mitomycin C for prevention of anterior glottic restenosis. This case and prior reports suggest that the novel approach may be effective in the treatment of laryngeal webs.
