The aim of this study is to analyze the transconjunctival approach in the treatment of orbital fractures and to evaluate the indications, the advantages of the surgical approach, and the occurrence of possible complications.
From 2005 to September 2009 we used a transconjunctival approach on 53 patients for a total of 56 cases of orbital fractures (three cases with bilateral floor fractures), 54 cases of acute trauma, and two outcomes of previous fractures. We evaluated the incidence of intra or postoperative complications and in the postoperative follow-up we investigated the presence of: entropion, ectropion, scleral show, trichiasis, conjunctival granuloma, mobilization or exposure of orbital reconstruction material.
In 56 cases we had four temporary postoperative complications and no long-term complications; two cases of trichiasis and two cases of partial entropion were treated only with medical therapy. All complications, as described in the literature, were transitory and did not require corrective surgery.
The transconjunctival approach is the most effective surgical access, not only to the medial orbital wall, but also to the orbital floor, as it does not interfere with the lachrymal drainage system and gives as wide a visualization of the orbital floor as does the palpebral approach. This surgical approach is simple to perform and gives good functional and aesthetic results.
本研究旨在分析经结膜入路治疗眼眶骨折,并评估手术适应证、手术入路的优点以及可能发生的并发症。
从 2005 年至 2009 年 9 月,我们使用经结膜入路治疗了 53 例患者,共 56 例眼眶骨折(3 例合并双侧眶底骨折),54 例急性创伤,2 例为陈旧性骨折。我们评估了术中或术后并发症的发生率,在术后随访中我们观察了以下情况:眼睑内翻、外翻、巩膜暴露、倒睫、结膜肉芽肿、眶重建材料的活动或暴露。
在 56 例中,我们有 4 例术后暂时并发症,无长期并发症;2 例倒睫和 2 例部分眼睑内翻仅通过药物治疗。所有并发症均如文献所述,是暂时的,不需要矫正手术。
经结膜入路是最有效的手术入路,不仅适用于内侧眶壁,也适用于眶底,因为它不干扰泪液引流系统,并能像睑下入路一样广泛地观察眶底。这种手术入路操作简单,可获得良好的功能和美学效果。
