Cicatricial posterior glottic stenosis. Our experience

Presentation of the results obtained in the treatment of cicatricial posterior glottic stenosis.

A retrospective study of 34 patients diagnosed and treated for cicatricial posterior glottic stenosis in our ENT Department.

In our series, 85.36% of our patients were decannulated. Of these, 80% of the patients with glottic stenosis were decannulated, while 92.9% of the patients with other associated laryngotracheal stenosis were paradoxically decannulated. Of all the patients, 70% required more than 1 surgical procedure, although most of these interventions were to resolve minor issues following our protocol. The number of subsequent interventions was determined by the location of the stenosis, with there being more interventions when the posterior glottic stenosis was associated with another type of laryngotracheal stenosis (p=.001).

The surgical results for treating cicatricial posterior glottic stenosis are quite positive. However, unlike other types of posterior glottic stenosis (such as neurogenic abductor paralysis), it requires a greater number of interventions to achieve definitive decannulation. Endoscopic procedures play an important role and represent our main tool.
