Bone cement in ossiculoplasty

ABSTRACT

This study included 30 patients having conductive hearing loss secondary to chronic otitis media with ossicular discontinuity. Biocompatible polymethylmethacrylate [PMMA] bone cement was used as a locally manufactured prosthesis for ossicular reconstruction in the forms of PORP and TORP. In ears with intact stapes superstructure, PORP was used [18 cases]; while, in ears with absent stapes superstructure, a similar TORP was used [12 cases]. The postoperative mean air-bone gap gain was 20 dB at the speech frequencies of 500 Hz-1000 Hz, 2000 Hz-4000 Hz in 22 cases. An extrusion of the prosthesis occurred in two cases. It was concluded that this locally made prosthesis is efficient in closing air-bone gap as well as cost- effective
