Abstract

Purpose: Aim of this study was to examine any stapes fixation-related clinical, intraoperative and high-resolution computed tomography (HRCT) findings in children undergoing stapedotomy. Procedures: Detailed diagnostic assessment was performed in 12 children (18 ears) who underwent stapedotomy within the period 2005–2008. Results: Ear malformations such as malleus-incus anomalies, malleus-epitympanum fixation and absence of the stapedius tendon, small external auditory canal and auricle malformations were clinically and/or intraoperatively diagnosed. HRCT identified a petrous high jugular bulb and malformed inner auditory canal in 4 ears; however, it failed to recognize ossicular fixation. Systemic anomalies, namely kyphoscoliosis, esophageal atresia and finger malformations were identified in 2 children. Summing up, additional anatomic anomalies were found in 8 patients (66.7%). Conclusions: Ear malformations may coexist in children with stapes fixation. Ossicular fixation is not easily recognized with HRCT, and therefore, ossicular mobility should always be tested intraoperatively. In a few cases, pediatric stapes fixation can coexist with systemic dysplasias; in such patients, additional referral to geneticists is recommended.
