Learning Objectives:
Objective: To assess the outcome and advantage of bony meatoplasty with cartilage reconstruction (BMCR) for stage IV(M) external auditory canal cholesteatoma (EACC) with specific invasion in mastoid cavity.
Methods: Retrospective review of six cases of stage IV(M) EACC. Three cases followed by traditional canal-wall-down tympano-mastoidectomy. The other three underwent cartilage reconstruction of bony meatoplasty without radical mastoidectomy.
Results and Conclusion: The preoperative symptoms of all six patients were otalgia, ear fullness and hearing loss. All HRCT demonstrated external auditory canal (EAC) lesions invasion into mastoid cavity. The follow up was between 21 months to 54 months and no recurrence occurred on any of the six patients. It was observed that the patients underwent bony meatoplasty with cartilage reconstruction could also achieve the result of eradicate the disease process. Moreover, compared with the traditional radical operation, BMCR was a minimal invasive approach that maintained the normal structure of EAC and shortened the healing time. The patients underwent BMCR also demonstrated better hearing and quality of life.
