Seventy-five patients were studied retrospectively to assess the prevalence and variance of temporomandibular dysfunction in an orthognathic surgery population. Preoperatively, 49.3% of the sample presented with temporomandibular dysfunction. After orthognathic surgery, of the symptomatic patients, 89.1% had improved temporomandibular function after surgery, 2.7% were unchanged, and 8.1% had increased symptoms. Of the patients asymptomatic prior to surgery, 7.9% developed temporomandibular dysfunction postoperatively. Temporomandibular dysfunction was significantly more prevalent in patients with a Class II skeletal deformity than in those with a Class III deformity, and temporomandibular function generally improved in both groups postsurgically.
对75例患者进行回顾性研究，以评估正颌外科手术人群中颞下颌关节功能障碍的患病率和变化情况。术前，49.3%的样本存在颞下颌关节功能障碍。正颌手术后，有症状的患者中，89.1%术后颞下颌关节功能改善，2.7%无变化，8.1%症状加重。术前无症状的患者中，7.9%术后出现颞下颌关节功能障碍。II类骨骼畸形患者的颞下颌关节功能障碍患病率明显高于III类畸形患者，两组术后颞下颌关节功能总体均有改善。
