第 51 題
嚴重中臉部畸形（midface deformities）合併眶下緣及顴骨發育不足（infraorbital rim and malar eminence deficiency），此時較適合之矯正術式為下列何者？
- A 勒福一型截骨術（Le Fort I osteotomy）
- B 勒福二型截骨術（Le Fort II osteotomy）
- C 勒福三型截骨術（Le Fort III osteotomy）
- D 上顎前段截骨術（upper anterior segmental osteotomy）
思路引導 VIP
請同學從解剖層次分析：在處理中臉部畸形時，哪一種術式的截骨路徑位階最高，且其設計能同時涵蓋眼眶下緣與顴骨（malar eminence），從而改善中臉部最深層且廣泛的發育缺陷？
