The aim of the presented study was to assess the impact of mandibular advancement on the upper airways patterns, on the position of soft palate, hyoid bone and tongue. The set of 12 patients who underwent bilateral sagittal split osteotomy advancement surgery only, without genioplasty, for correction of retromandibularism (skeletal class II malocclusions) was evaluated. Rigid internal fixation was used in all the patients without rigid intermaxillary fixation. Measurements were taken in cephalograms obtained after the orthodontic decompensation and immediately after the surgery. In the set of patients who underwent advancement of the mandible the air passage of upper airways at the level of oropharynx was recorded and significant improvement was proved.
本研究的目的是评估下颌前伸对上气道形态、软腭位置、舌骨和舌头位置的影响。对12例仅接受双侧矢状劈开截骨前徙手术（未行颏成形术）以矫正下颌后缩（骨性II类错牙合畸形）的患者进行了评估。所有患者均采用坚固内固定，未使用坚固颌间固定。在正畸去代偿后及手术后即刻获得的头颅侧位片中进行测量。在接受下颌前伸的患者组中，记录了口咽水平上气道的气道情况，并证实有显著改善。
