Abstract
Introduction and objectives

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

Methods

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

Results

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).

Conclusions

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.

Resumen
Introducción y objetivos

Presentar los resultados obtenidos en el tratamiento de estenosis glóticas posteriores cicatriciales.

Métodos

Estudio retrospectivo de 34 pacientes diagnosticados y tratados de estenosis glóticas posteriores cicatriciales por nuestro servicio.

Resultados

El 85,36% de nuestros pacientes fueron decanulados. Los pacientes con estenosis de localización únicamente glótica fueron decanulados en un 80%, mientras que paradójicamente en los que tenían asociada además otro tipo de estenosis laringotraqueal, el porcentaje de decanulación fue del 92,9%.

El 70% de los pacientes requirieron más de un procedimiento quirúrgico, aunque la mayoría de ellos se hicieron por protocolo y con la finalidad de resolver pequeños problemas.

El número de reintervenciones está condicionado por la localización de la estenosis, siendo mayor cuando la estenosis glótica posterior se asocia a otro tipo de estenosis laringotraqueal (p=0,001).

Conclusiones

Los resultados quirúrgicos obtenidos en el tratamiento de las estenosis glóticas posteriores cicatriciales son buenos, pero a diferencia de otro tipo de estenosis glóticas posteriores (como por ejemplo las parálisis de abductores de origen neurogénico) requieren más intervenciones para la decanulación definitiva.

Los procedimientos endoscópicos juegan un papel destacado y suponen nuestra principal herramienta de trabajo.
