“…1,[16][17][18][19][20] In addition to single-case reports, there were also eight studies with the total number of cases less than 10. 3,7,[21][22][23][24][25][26] Looking at the meta-analysis graph, we can see that small squares for each study are shown in different sizes depending on the sample size. Studies that reported more successful surgical results appear in the graph to be leaning to the right, whereas unsuccessful ones appear to be leaning to the left.…”

“…In addition, current literature is now focusing on the potential role of cone beam CT, which has demonstrated similar efficacies with a lower radiation dose as compared with HRCT [ 21 ]. Malposition of the facial nerve is often associated with oval window atresia [ 20 , 22 ]. It has been suggested that this may prevent contact between the stapes and otic capsule, thus inhibiting normal development of both structures [ 23 ].…”

The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.

“…On the other hand it was also reported that inner ear fenestration surgery results in improvement in hearing with stable results [12]. 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].…”

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.
