“…In addition, vestibulotomy in cases of oval window absence is a relatively safe and effective procedure, which can be performed even in the presence of abnormal facial nerve passing under the oval window or its area in cases of oval window dysplasia [17]. Despite the difference in results, stapedectomy for congenital fixation remains an effective method to achieve significant hearing improvement in the majority of patients [18]. In our experience, the hearing of the patients improved after the surgery.…”

Objective: To present the results of our experience with labyrinthotomy or vestibulotomy in cases where the oval window is blocked by the facial nerve and in the presence of bilateral congenital agenesis of the oval window, respectively. Study design: Retrospective analysis of the records of the patients operated in two different centers. Methods: Between 2007 and 2012, 5 ears of 4 patients who were operated on in two different clinics with a presumptive diagnosis of otosclerosis were included in the study. There were 3 female patients and 1 male. The ages ranged from 10 to 26 (mean 19 years). All patients had unilateral conductive hearing loss except 1 (10-year-old girl or patient 1). Pure tone averages were calculated at the frequencies 0.5, 1, 2 and 4 kHz both pre- and postoperatively according to the Committee on Hearing and Equilibrium 1995 Guidelines for the Evaluation of Results of Treatment of Conductive Hearing Loss. All patients underwent a middle ear exploration and postoperatively the initial audiological examination was performed after 6 months. Results: Retrospective analysis revealed that vestibulotomy or labyrinthotomy was performed in 5 ears of 4 patients. Postoperative dizziness was encountered in 2 patients who had vestibulotomy due to oval window agenesis, which ceased spontaneously at 1 month postoperatively. The perioperative period was otherwise uneventful. None of the patients had sensorineural hearing loss or deterioration of hearing. There was a significant improvement in hearing after the operation. A 28-dB improvement in the mean air conduction pure tone thresholds was achieved. Conclusion: Vestibulotomy and labyrinthotomy are safe and effective procedures in terms of hearing restoration, which can be applied in cases of congenital agenesis of the oval window or obstruction of the oval window by the facial nerve.

“…Though there is ample experience with stapes surgery in adults, stapedotomy seems to be rarely performed in children [1][2][3][4]7] . Two retrospective studies involving stapes surgery performed in children in 7-year periods, 1994-2001 and 1996-2003, revealed 66 and 36 ears, respectively [2,4] .…”

“…Whether stapedectomy or stapedotomy, operative intervention achieves an air-bone gap closure of 10 dB in 1 78% of adults suffering from otosclerosis [1][2][3] . The high prevalence of otosclerosis in adults with conductive hearing loss resulted in an adequate evaluation of the disease-related parameters.…”

“…Although the operative outcome in children is reported to be favorable, the closure of the air-bone gap is sometimes less satisfactory than in adults [2][3][4][5][6][7][8] . The great heterogeneity in the underlying pathology, namely tympanosclerosis, congenital stapes ankylosis and juvenile otosclerosis, affects the final outcome of stapes surgery [4][5][6][7][8] .…”

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.
