Severe to profound Sensorineural Hearing Loss is a challenging medical problem, particularly if this condition is associated with an inner ear anomaly. This case series studies the prevalence of inner ear anomalies among 76 consecutive prospective cochlear implant candidates who presented to our tertiary care hospital over 2 years. Inner ear anomalies were identified in 11 cases with a prevalence rate of 14%. Narrow Internal Auditory Canal (IAC) is the most common inner ear anomaly (5) followed by Mondini (3) and Globular vestibule (3). Combined CT and MRI play an important role in the preoperative assessment of inner ear anomalies which may affect not only the decision to perform the Implant procedure and the prognosis but also the choice of implant and surgical technique.
重度至极重度感音神经性听力损失是一个具有挑战性的医学问题，尤其是当这种情况与内耳异常相关时。本病例系列研究了连续76例在两年内就诊于我们三级医疗中心的潜在人工耳蜗植入者内耳异常的患病率。在11例中发现了内耳异常，患病率为14%。内耳道狭窄（IAC）是最常见的内耳异常（5例），其次是Mondini畸形（3例）和球状前庭（3例）。CT和MRI联合在内耳异常的术前评估中起着重要作用，这不仅可能影响植入手术的决策和预后，还会影响植入物的选择和手术技术。
