The modified Hughes repair of the lower eyelid (upper lid tarsoconjunctival flap and skin graft or flap) after resection of marginal lesions has an established place in oculoplastic surgery. Previous recommendations for the timing of the division of the conjunctival pedicle have varied greatly from 3 weeks to 6 months. This study was performed to determine the safety of division of the pedicle at 2 weeks.
A series of 25 patients in whom the tarsoconjunctival pedicle in a modified Hughes repair of the lower eyelid was divided at 2 weeks were prospectively evaluated. All cases had a full-thickness skin graft placed as an anterior lamella of the reconstructed eyelid.
In all cases there was a healthy and viable lower lid with brisk bleeding from the newly created lid margin at the time of pedicle division. There were no instances of infarction of any portion of the reconstruction, shrinkage, or retraction of the lower lid.
Two weeks is a long enough time to wait prior to division of the conjunctival pedicle in the modified Hughes repair of the lower eyelid.
在眼睑整形手术中,切除边缘性病变后采用改良休斯修复法(上睑睑板结膜瓣及植皮或皮瓣)修复下睑已确立了其地位。以往关于结膜蒂切断时机的建议差异很大,从3周至6个月不等。本研究旨在确定在2周时切断蒂的安全性。
对25例在改良休斯修复下睑时于2周切断睑板结膜蒂的患者进行前瞻性评估。所有病例均采用全厚皮片作为重建眼睑的前层。
在所有病例中,切断蒂时均有一个健康且存活的下睑,新形成的睑缘有活跃出血。重建的任何部分均未出现梗死、下睑收缩或退缩的情况。
在改良休斯修复下睑时,在切断结膜蒂之前等待2周的时间足够长。
