下眼瞼重建手術
Small defect ( < 33%)
=> 外眥切開術(canthotomy)後,再直接縫合
Moderate defect (33~50%)
=> semicircular rotation (可至50% defect)
Large defect ( > 50%)
* Hughes procedure (tarsoconjunctval flap from upper eyelid + skin graft) 最為理想
=> 若skin graft由它處取得,則叫modified Hughes procedure
=> modified Hughes procedure 需要蓋住pupil數週,屬Sharing-lid,應避免用於7歲以下小朋友,怕造成amblyopia
其它可修補更大範圍lid defect的procedre
* Cutler-Beard procedure (Full-thickness lower eyelid advancement)
* Tenzel semicircular rotation
=> 上兩種容易有round canthus的結果,應該不若Hughes procedure理想。
上瞼修補比下瞼修補更複雜,更難!
