The purpose of this study was to document the prevalence of disk displacement and temporomandibular joint symptoms in orthognathic surgery patients. Fifty-three consecutive patients with different types of dentofacial anomalies were examined clinically and with bilateral arthrography. Disk displacement unilaterally or bilaterally was found in 57% of the patients or 46% of the joints. Displacement with reduction was seen in 38 joints, and displacement without reduction was seen in 11 joints. Fifty-three percent of the patients had pain in the temporomandibular joint or masticatory muscles, 30% of the joints demonstrated clicking, and 4% had crepitation. No association was found between disk displacement and clinical symptoms except for an association between clicking and anterior disk displacement with reduction. Neither could an association between disk displacement and the type of dentofacial anomaly be appreciated. It was concluded that disk displacement was frequent in patients with dentofacial anomalies, but no relationship to temporomandibular joint symptoms and the type of dentofacial anomaly could be clearly demonstrated.
本研究的目的是记录正颌外科手术患者中盘状移位和颞下颌关节症状的患病率。对53例连续的不同类型牙颌面畸形患者进行了临床检查和双侧关节造影。57%的患者或46%的关节存在单侧或双侧盘状移位。可复性移位见于38个关节，不可复性移位见于11个关节。53%的患者有颞下颌关节或咀嚼肌疼痛，30%的关节有弹响，4%有关节摩擦音。除弹响与可复性前盘移位之间存在关联外，未发现盘状移位与临床症状之间存在关联。盘状移位与牙颌面畸形类型之间也未发现关联。得出的结论是，牙颌面畸形患者中盘状移位很常见，但与颞下颌关节症状及牙颌面畸形类型之间的关系尚不能明确证实。
