Subtotal petrosectomy for extensive cholesteatoma: A case series from Japan

STP is an option for managing extensive primary cholesteatoma where hearing reconstruction is not feasible, particularly in the elderly population. However, the risk of residual cholesteatoma is significant, as evidenced by a 27 % recurrence rate in this series, and careful surgical indication is essential to avoid potential over-indication. This finding highlights the critical importance of meticulous surgical technique and rigorous postoperative imaging surveillance to ensure long-term disease control.
