“…According to the literature, class I anomalies can achieve 80% success, with the mean gain varying from 21 to 40 dB [Teunissen and Cremers, 1991;Albert et al, 2006;Thomeer et al, 2010]. Our success rates did not match those described, but it is noteworthy that in our study, this ossicular malformation was present in 8 ears, and among these, 2 had sensorineural impairment and 1 a prosthesis displacement leading to the need for hearing aids.…”

“…To our knowledge, there is one study in the literature dealing with isolated congenital stapes ankylosis in a pediatric population [Albert et al, 2006] and another dealing with ossicular malformations associated with a mobile footplate [Philippon et al, 2013]. Among the pediatric population in this current study, hearing impairment as a result of congenital ossicular chain anomalies was observed.…”

The aim of this study was to describe the audiometric results following surgery in a consecutive series of pediatric patients with a congenital middle ear disorder. Retrospective chart review was performed for 29 consecutive children who underwent 33 middle ear surgeries for congenital ossicular chain anomaly between 1990 and 2012. Anomalies were classified into four groups according to the Teunissen and Cremers classification. Audiological parameters using four frequency averages (0.5, 1, 2 and 4 kHz) were assessed pre- and postoperatively. Clinical and audiometric follow-up times were, respectively, 49 ± 8 and 35 ± 5 months (mean ± SEM). Fifty-eight percent of all patients achieved an air-bone gap (ABG) ≤20 dB, 62.5% in class I, 50% in class II and 57.9% in class III. The improvement of the mean ABG was 13.6 dB, 19.2 dB for class I, 0.2 dB in class II and 15.4 dB in class III. Overall mean pure-tone averages improved 14.8 dB with 13.9 dB for class I; there was no improvement for class II and 20.2 dB for class III. The sensorineural hearing loss rate was 9%. This pediatric series showed that hearing results depend on type of anomaly. Class I and class III showed better hearing improvement than class II.

CT scan is important in case of suspected middle ear malformation, since it demonstrates the best anatomic details for surgical planning and thus avoiding unfortunate intraoperative events, secondary to variations in the course of vessels and nerves, but could not show limited ossicles abnomalies.…”

The aim of this study is to investigate the contribute of the endoscopic exclusive transcanalar approach for the management of stapes malformations. A retrospective chart review was made at our tertiary referral centers. 17 patients with stapes malformations underwent surgery with endoscopic exclusive transcanal approach. A complete audiological and radiological assessment before and after surgery was performed. 12/17 (70 %) underwent a surgical endoscopic correction, In case of fixed platina underwent five endoscopic stapedotomy and one endoscopic stapedectomy were performed. In case of mobile platina five endoscopic ossiculoplasties with partial ossiculoplasty replacement prosthesis were performed, 3 with autologous remodeling incus and 2 with malleus head remodeling. In 1 case, only an endoscopic stapes mobilization was made. In 5/17 (30 %), due to difficult anatomical findings an endoscopic explorative tympanotomy was finally performed. The mean preoperative air conduction (AC), bone conduction (BC) and air-bone gap (ABG) were, respectively, 60.7, 26.3 and 34.4 dB. The mean postoperative AC, BC and ABG were, respectively, 33.8, 26.5 and 7.3 dB, with a mean improvement of the ABG of 27.1 dB. Discharge from hospital was on the first post-surgery day. No relevant postoperative complications were noted. The median follow-up was 3.6 years (range 1-6). The endoscopic approach results very adequate for the diagnosis and treatment of stapes malformations, checking variations of the ossicles conformation and functioning and performing safe surgery, under direct control of middle ear structures.

“…Due to this variety of stapes-related pediatric pathologies, confusion of terms such as 'congenital stapes ankylosis' and 'juvenile otosclerosis' is not uncommon in the literature [5] . Congenital stapes ankylosis and juvenile otosclerosis result in the fixation of the stapes and can both be successfully treated with the same operative intervention.…”

“…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] . The congenital basis seems to be common underlying etiology.…”

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.
