BACKGROUND
Few reports have described the ophthalmic complications that occur after maxillary orthognathic surgery. Since cases of decreased reflex tearing after maxillary orthognathic surgery are extremely rare, we describe 2 cases of loss of reflex tearing after maxillary orthognathic surgery.
CASE PRESENTATION
Two Asian women, an 18-year-old and a 32-year-old, suffered from unilateral dryness and irritation caused by maxillary orthognathic surgery. In both patients, Schirmer test (II) showed reduced reflex tearing in 1 eye. Computed tomography showed that the pterygoid plate had been fractured in both patients.
CONCLUSIONS
The pterygopalatine ganglion and its associated fibers in the pterygopalatine fossa may be injured during Le Fort osteotomy.
背景
鲜有报道描述上颌骨正颌手术后出现的眼部并发症。由于上颌骨正颌手术后出现反射性流泪减少的情况极为罕见，我们描述了 2 例上颌骨正颌手术后出现反射性流泪丧失的病例。
病例介绍
两名亚洲女性，分别为 18 岁和 32 岁，均因上颌骨正颌手术而出现单侧干涩和刺激症状。两名患者的 Schirmer 试验（II）均显示单眼反射性流泪减少。计算机断层扫描显示两名患者的翼板均发生骨折。
结论
在 Le Fort 截骨术中，翼腭窝内的翼腭神经节及其相关纤维可能会受到损伤。
