Objective

The main objective of our study is to identify whether there is measurable audiometric deterioration in patients undergoing stapedotomy with a follow-up of more than 8 years.

Material and method

We conducted a retrospective clinical study in which we reviewed a total of 150 case histories of patients with stapedotomy at our department between 1993 and 1997, with a successful initial audiological assessment using tone audiometry in the first 3 months after surgery and later audiometrical follow-up.

Results

We obtained a significant mean post-operative hearing impairment of 1.02 dB per year, with a pre-operative mean PTAof 51.45 dB, going on to early post-operative mean PTAof 26.71 dB, and later post-operative mean PTAof 35.42 dB, with all these changes turning out to be statistically significant.

Conclusions

The auditory level obtained after surgery worsens as the years go by, but always without exceeding the hearing loss prior to surgery.

Objetivo

Nos propusimos valorar el deterioro audiométrico de los pacientes intervenidos de estapedotomía, con un seguimiento mayor de 8 años.

Material y método

Realizamos un estudio clínico retrospectivo en el que revisamos un total de 150 historias de pacientes intervenidos de estapedotomía entre los años 1993 y 1997 en nuestro servicio, con buen resultado audiológico inicial valorado mediante audiometría tonal en los primeros 3 meses tras la cirugía y con seguimiento audiométrico posterior.

Resultados

Obtuvimos una media de deterioro auditivo postoperatorio significativa (1,02 dB por año), con una media auditiva preoperatoria de 51,45 dB, que pasa a una media de 26,71 dB en el postoperatorio temprano, y una media de 35,42 dB en el postoperatorio tardío; todos estos cambios son estadísticamente significativos.

Conclusiones

El nivel auditivo obtenido tras la cirugía empeora con el paso de los años; pero siempre sin sobrepasar la pérdida auditiva previa a la cirugía.
