BACKGROUND: Congenital middle ear anomalies are primarily managed surgically, but data on facial nerve anomalies and bilateral cases are limited.
OBJECTIVE: To report endoscopic outcomes for congenital middle ear anomalies, focusing on facial nerve anomalies and bilateral consistency.
METHODS: Retrospective review of 33 patients (41 ears) from 2021 to 2025. Anomalies were intraoperatively classified using the Teunissen system. All underwent endoscopic, class-specific ossicular reconstruction. Facial nerve anomalies recorded. Audiometric outcomes (ABG, 8 kHz) were analyzed. Complications recorded.
RESULTS: The cohort had 57.6% unilateral and 42.4% bilateral cases. Facial nerve anomalies in 41.5% of ears. In all eight patients who underwent staged bilateral surgery, the ossicular and facial nerve patterns were identical between the two ears. Mean ABG improved from 39.7 ± 9.5 dB to 14.5 ± 5.4 dB (p < 0.001). Successful hearing (ABG ≤ 20 dB) achieved in 87.8% (Class I 80%, II 80%, III 95.2%, IV 80%). No sensorineural hearing loss (SNHL) or facial palsy.
CONCLUSION: Congenital middle ear anomalies are frequently associated with facial nerve malformations and may exhibit bilateral symmetry in staged cases, offering preoperative insight. An endoscopic, classification-based approach yielded encouraging hearing outcomes and a favorable safety profile, even with complex facial nerve anomalies. These findings are preliminary, limited by retrospective design and sample size.
