RESUMO
Posterior glottic stenosis or interarytenoid fibrous adhesion is uncommon and has sometimes been misdiagnosed as cord paralysis. Laryngoscopy and laryngeal electromyography studies are the two main diagnostic aids. We present the case of a 63-year-old man under endotracheal intubation during 10 days after a cardiac procedure who was evaluated in our department for persistent dysphonia. The laryngoscopy showed a granuloma-like lesion in the posterior glottic space. During the microlaryngoscopy procedure, the osseous consistence of the interarytenoid lesion was observed. Laser surgery excision of the lesion was performed with good results. According to our review of the literature, this corresponds to the second case reported.

La estenosis glótica posterior por fijación interaritenoidea es muy poco común, y a veces se diagnostica como parálisis de las cuerdas. La laringoscopia y electromiografía laríngea son los métodos diagnósticos principales. Presentamos un paciente varón de 63 años, que estuvo intubado 10 días después de un procedimiento cardíaco. Se valoró en nuestra consulta por disfonía. La endolaringoscopia mostró un granuloma en el espacio glótico posterior. La microcirugía endolaríngea mostró la consistencia ósea de la lesión. Posteriormente se realizó una excisión láser con buenos resultados a largo plazo. Según nuestra revisión este caso sería el segundo reportado en la literatura(AU)
