10 patients were evaluated retrospectively for their long-term changes in hypopharyngeal airway space after surgical correction of mandibular prognathism. All patients had undergone mandibular setbacks by way of bilateral sagittal split osteotomies with rigid fixation. The cephalometric evaluation of the hypopharyngeal airway space was based on stable craniofacial landmarks. The results of this study indicate that mandibular setbacks procedures create relative narrowing of the hypopharyngeal airway space, which in isolated cases might contribute to the development of an obstructive sleep apnea syndrome. The clinical implications of these findings are discussed.
对10例下颌前突手术矫正后下咽气道空间的长期变化进行了回顾性评估。所有患者均通过双侧矢状劈开截骨术加坚固内固定进行下颌后缩。下咽气道空间的头影测量评估基于稳定的颅面标志点。本研究结果表明，下颌后缩手术会导致下咽气道空间相对变窄，在个别情况下可能会导致阻塞性睡眠呼吸暂停综合征的发生。讨论了这些发现的临床意义。
