Abstract
Objective

To identify predictive factors for ear-nose-throat (ENT) complications in patients undergoing skull base surgery via extended endoscopic endonasal approaches (EEEA).

Methods

Single-center retrospective observational study of a cohort of patients who underwent EEEA for skull base surgery between January 2015 and December 2021. Patients were stratified according to ENT complications.

Results

Sixty-one patients were included in the study: 37 women (60.66%) and 24 men (39.34%). Craniopharyngioma was the most frequently observed pathology (36%). 40 patients (65,57%) presented with ENT complications, being olfactory disturbance the most common complication (40,98%), followed by nasal obstruction (24,59%) and synechiae formation (18,03%). Logistic regression analysis revealed that younger age (P = .026) and excision of middle turbinates during EEEA surgery (P = .034) were independent factors with a significant association with ENT complications. Anterior septal deviation was an independent factor significantly associated with synechiae formation (P = .023).

Conclusion

Surgeons performing skull base surgery using EEEA should be aware that excision of middle turbinate, younger age and anterior septal deviation may be risk factors for ENT postoperative complications.

Resumen
Objetivo

Identificar factores predictivos de complicaciones otorrinolaringológicas (ORL) en pacientes sometidos a cirugía de base de cráneo mediante abordajes endonasales endoscópicos extendidos (AEEE).

Métodos

Estudio observacional retrospectivo unicéntrico de una cohorte de pacientes sometidos a AEEE para cirugía de base de cráneo entre enero de 2015 y diciembre de 2021. Los pacientes fueron estratificados según las complicaciones ORL.

Resultados

Se incluyeron 61 pacientes en el estudio: 37 mujeres (60,66%) y 24 hombres (39,34%). El craneofaringioma fue la patología más frecuente (36%). 40 pacientes (65,57%) presentaron complicaciones ORL, siendo la alteración olfatoria la complicación más frecuente (40,98%), seguida de la obstrucción nasal (24,59%) y la formación de sinequias (18,03%). El análisis de regresión logística reveló que la menor edad (P = ,026) y la escisión de los cornetes medios durante la cirugía de AEEE (P = ,034) eran factores independientes con una asociación significativa con las complicaciones ORL. La desviación septal anterior fue un factor independiente asociado significativamente a la formación de sinequias (P = ,023).

Conclusión

Los cirujanos que realizan cirugía de la base del cráneo mediante AEEE deben ser conscientes de que la escisión de los cornetes medios, la edad más joven y la desviación septal anterior pueden ser factores de riesgo de complicaciones ORL postoperatorias.
