無症狀術後囊狀膽脂瘤復發之等待掃描策略：一種新穎的管理方法

// A Wait and Scan Protocol for Asymptomatic Postsurgical Cholesteatoma Recurrence: A Novel Management Strategy

本研究評估採用主動MRI監測取代立即手術治療小型無症狀術後膽脂瘤復發的可行性與安全性｜13位患者進行每12至18個月一次的擴散加權MRI掃描，77%患者於平均43個月追蹤期間免於手術｜病灶生長速率低且部分病灶自發退化，顯示MRI監測可安全延遲手術，具臨床應用潛力，建議進一步影像導引管理研究。

// This study assessed the feasibility and safety of active MRI surveillance instead of immediate surgery for small, asymptomatic postoperative cholesteatoma recurrence. Thirteen patients underwent serial non-echo-planar diffusion-weighted MRI scans every 12-18 months, with 77% remaining surgery-free over a mean follow-up of 43 months. The mean lesion growth rate was low, and some lesions regressed spontaneously. The results suggest that MRI surveillance can safely delay surgery in selected patients, warranting further research on imaging-guided management.
