    Abstract:
    OBJECTIVE: To examine hearing results in pediatric patients after ossicular reconstruction with partial ossicular replacement prostheses (PORPs) and total ossicular replacement prostheses (TORPs) in children with chronic otitis media. METHODS: A retrospective chart review was performed on 55 pediatric patients with chronic otitis media who underwent ossicular reconstruction from 1991 to 1998. Patients' audiograms were evaluated preoperatively and postoperatively for pure-tone average (PTA), air-bone gap (ABG), speech reception threshold (SRT), method of ossicular reconstruction, and management of the mastoid. RESULTS: Twenty-seven patients underwent ossicular reconstruction with TORPs. The average preoperative ABG was 40.1 dB, and the average postoperative ABG was 31.6 dB. Forty-one percent of the children improved their PTA greater than 10 dB postoperatively, and 52% of children did not change their ABG by more than 10 dB postoperatively. Nineteen percent of children with TORPs had a postoperative ABG less than 20 dB, and 44% of children with TORPs had a postoperative ABG less than 30 dB. Twenty-eight patients underwent ossicular reconstruction with PORPs. The average preoperative ABG was 29.7 dB, and the average postoperative ABG was 22.5 dB. Thirty-two percent of patients improved their PTA by greater than 10 dB, while 57% of children with PORPs did not change their ABG by more than 10 dB postoperatively. Forty-three percent of children with PORPs had an ABG of less than 20 dB postoperatively, and 71% of children with PORPs had a postoperative ABG less than or equal to 30 dB. CONCLUSIONS: Children who underwent ossicular reconstruction with PORPs had slightly better postoperative hearing than did children with TORPs. Postoperative hearing was essentially unchanged in approximately 55% of both groups. Preoperative hearing levels may be the most important factor determining postoperative hearing in nonstaged surgery for children with chronic otitis media Long-term hearing results in children with single-stage surgery were not as good as those reported in the literature for staged surgery. Severe mucosal disease and eustachian tube dysfunction may contribute to poorer hearing results in children.
