Malfunctions of the eustachian tube after Le Fort I osteotomies are rare. A 22-year-old woman was treated by Le Fort I osteotomy for maxillary retrognathism. Postoperatively she developed recurrent tubal malfunction and middle ear effusions on the left side, with no improvement after adenotomy, tonsillectomy, and grommet insertion. In consecutive computed tomography and magnetic resonance imaging scans, a forward dislocation of the left pterygoid hamulus was demonstrated. In addition, damage to the tensor veli palatini muscle was evident. Both postoperative sequelae appear to be responsible for the unilateral tubal dysfunction.
勒福Ⅰ型截骨术后咽鼓管功能障碍较为罕见。一名22岁女性因上颌后缩接受勒福Ⅰ型截骨术治疗。术后她左侧反复出现咽鼓管功能障碍和中耳积液，在进行腺样体切除术、扁桃体切除及鼓膜置管术后仍无改善。在连续的计算机断层扫描和磁共振成像扫描中，显示左侧翼突钩向前脱位。此外，腭帆张肌损伤明显。这两种术后后遗症似乎是导致单侧咽鼓管功能障碍的原因。
