Hearing rehabilitation with an intracochlear prosthesis is well documented in patients who have an intact otic capsule prior to implantation. However, the suitability for implantation of patients who have undergone extensive procedures involving the otic capsule such as labyrinthectomy has not been directly addressed. This report documents a case of a patient deafened by a transmastoid labyrinthectomy who subsequently received a cochlear implant. Postimplantation performance of this patient was compared with the performance of three other postlingual implant recipients. The results suggest that labyrinthectomy is not a contraindication to auditory rehabilitation by a cochlear implant. The implications of implantation in a surgically manipulated otic capsule are discussed.
对于植入前耳囊完整的患者，使用人工耳蜗进行听力康复已有充分记录。然而，对于那些已经接受了涉及耳囊的广泛手术（如迷路切除术）的患者，其植入的适用性尚未得到直接探讨。本报告记录了一例因经乳突迷路切除术致聋的患者，该患者随后接受了人工耳蜗植入。将该患者植入后的表现与其他三名语后聋植入受者的表现进行了比较。结果表明，迷路切除术并非人工耳蜗听觉康复的禁忌症。文中还讨论了在经过手术操作的耳囊中进行植入的意义。
