The accepted surgical method for telecanthus repair is transnasal wiring. This procedure requires a stable posterior lacrimal crest on the affected side and surgical manipulation of the wires as they exit the contralateral side. A method for repairing telecanthus that obviates these prerequisites is presented. Indications for use of this technique and comparison to transnasal wiring is discussed.
A Y-shaped titanium rigid orbital plating system ("miniplate") was used to surgically correct traumatic telecanthus in five patients, two in the acute setting and three in late reconstruction. The miniplate was cantilevered from the lateral aspect of the nose and directed posteriorly into the orbit. This provided a stable fixation point for the medial canthal tendon.
Marked resolution of the telecanthus was noted in four patients. No post-operative complications have been encountered to date.
Miniplate fixation was used successfully to repair unilateral traumatic telecanthus. Miniplate fixation of the medial canthal tendon should be considered in unilateral cases of traumatic telecanthus and in cases where poor bony support for transnasal wires is evident.
公认的修复内眦间距增宽症的手术方法是经鼻穿线术。该手术需要患侧有稳定的泪后嵴,并且在钢丝穿出对侧时需要进行手术操作。本文介绍了一种无需这些前提条件的修复内眦间距增宽症的方法。讨论了该技术的使用指征以及与经鼻穿线术的比较。
使用一种Y形钛质刚性眼眶钢板系统(“微型钢板”)对5例患者的外伤性内眦间距增宽症进行手术矫正,其中2例为急性期,3例为晚期重建。微型钢板从鼻外侧悬臂伸出并向后插入眼眶。这为内眦肌腱提供了一个稳定的固定点。
4例患者的内眦间距增宽症有明显改善。迄今为止未出现术后并发症。
微型钢板固定术成功用于修复单侧外伤性内眦间距增宽症。对于单侧外伤性内眦间距增宽症以及经鼻钢丝固定的骨支撑明显不足的病例,应考虑采用微型钢板固定内眦肌腱。
