Abstract
ObjectiveTo compare outcomes of stapedectomy in patients with congenital stapes fixation versus juvenile otosclerosis. MethodsA retrospective chart review was performed from January 1, 1999 until January 1, 2011 to identify patients under 18 years old who underwent a stapedectomy. Age, gender, pre- and postoperative audiograms, intraoperative findings including etiology of stapes fixation, prosthesis type, and complications were recorded. ResultsTwenty-two children were identified who had undergone a stapedectomy (two patients underwent sequential bilateral surgery) resulting in a total of 24 ears. The cause of fixation included juvenile otosclerosis (n=7) and congenital stapes fixation (n=17). The overall mean pre-operative air-bone gap (ABG) was 34.7dB (SD: 13.5) compared to a postoperative mean ABG of 9.0 (SD: 9.3) (p<0.001). The mean postoperative ABG of 9.6 (SD: 10.5) in the congenital stapes fixation group was similar to the mean postoperative ABG of 7.2dB (SD: 5.4) in children with juvenile otosclerosis (p=0.6). Two patients developed delayed profound sensorineural hearing loss approximately two weeks after surgery. One patient with profound sensorineural hearing loss recovered to a profound mixed hearing loss with a speech discrimination score of 80%. ConclusionsPediatric stapedectomy has comparable results to stapedectomy in adults regardless of the cause of stapes fixation; however, delayed sensorineural hearing loss may be higher in the pediatric population.
