Introduction. Osteal defects of the middle and posterior cranial fossa within the middle ear are rare but sever complication of chronic otitis media, which may lead to patient’s death.
Aim. The aim of the study was to report a group of patients operated for chronic ear infection in whom osteal defects of the middle and posterior cranial fossa were found during surgery, and to assess the ways of reconstruction.
Materials and methods. Retrospective analysis of 338 patients hospitalized at the Otolaryngology Department of the Jagiellonian University in Cracow between 1998-2002.
Results. In 21 out of 338 (6.2%) cases, defects of middle and/or posterior cranial fossa were found during surgery. In cases of extensive (over 1 cm dia.) defects we performed three-layered reconstruction: temporal fascia-bone-temporal muscle. Temporal fascia, cartilage, skin or wax were used to repair smaller defects.
Conclusions. Osteal defects of the middle and posterior cranial fossa are present in a significant percent of patients with chronic otitis media. Temporal fascia and patient’s bone appeared to be very good materials for the reconstruction.
