The transconjunctival inferior fornix incision provides access to the floor, rim, lateral, and inferior medial walls of the orbit. Complications of this surgical approach to the orbit are known to be rare but heretofore have not been clearly defined. Over an 8-year period, in an estimated 1200 cases, the authors have encountered cicatricial entropion, lower eyelid retraction, canthal dehiscence, lower eyelid avulsion, canalicular laceration, buttonhole laceration of the lower eyelid, conjunctival chemosis, and lacrimal sac laceration. Attention to anatomic landmarks and sound surgical execution will prevent these complications in most patients.
经结膜下穹窿切口可进入眼眶底部、眶缘、外侧壁及内侧下壁。已知这种眼眶手术方法的并发症很少见，但迄今为止尚未明确界定。在8年的时间里，在估计1200例病例中，作者遇到了瘢痕性睑内翻、下睑退缩、眦部裂开、下睑撕脱、泪小管撕裂、下睑扣眼状撕裂、结膜水肿和泪囊撕裂。在大多数患者中，注意解剖标志并合理进行手术操作可预防这些并发症。
