[The mastoid surgery in children at the Doce de Octubre Hospital. Review of the years 1988-1991]. / Cirugía de la mastoides en niños en el Hospital Doce de Octubre. Revisión de los años 1988-1991.

A study was made of 21 children with cholesteatoma and chronic otitis media between 1989 and 1991. We reviewed diagnostic tools, presurgical data, surgical procedures and results. Certain aspects of special relevance such as congenital anomalies and presurgical complications, are emphasized. The procedure of choice was mastoid tympanoplasty with the canal wall down, which is preferred in children. Hearing results were poor, partially caused by the process of bone resorption and by the surgical technique used. The incidence of persistent disease and recurrent cholesteatoma was high but we achieved a good control of the disease development because the canal wall down procedure allowed visualization and cleaning of the mastoid cavity.

[Congenital medially invasive cholesteatoma of the temporal bone: supralabyrinthine dissemination and possible origin in the area of the geniculate ganglion]. / Colesteatoma congénito medialmente invasivo de hueso temporal: vía de diseminación supralaberíntica y posible origen en área de ganglio geniculado.

Congenital cholesteatoma appears in about 2% of all cholesteatomas. The possibility of deep extension producing a medially invasive petrous bone cholesteatoma is very uncommon because congenital cholesteatomas are not as aggressive as acquired ones. The onset of facial palsy in a patient with a history of several years of hearing loss must suggest this possibility. We reviewed in this report the main concepts on this subject after bibliographic review and a case report.
