顎変形症患者に対する顎矯正手術後アンケート調査

Abstract

To assess whether patients were satisfied with the results of treatment, questionnaires were sent to 291 patients who had undergone orthognathic surgery for correction of jaw deformities and 133 questionnaires were returned with valid answers. The chief problem of 94 (71%) of these patients was appearance. Dysfunctions such as masticatory disturbance and speech difficulties were the primary reason for which 38 (29%) of the patients sought treatment. Seventy-five percent of the patients answered that they were satisfied with the results in regard to their chief problems. A favorable change in appearance was recognized by 125 patients, whereas five patients noticed no major changes and three patients were displeased with their postoperative faces. The patients'evaluations of their appearance seemed to be influenced by the responses of other peoPle to the surgical-results, and objective improvements did not always satisfy their expectations. Improvements in masticatory function and speech were recognized by 92 and 54 patients, respectively. Eighty patients had TMJ signs and symptoms such as click and/or pain before treatment, which disappeared in 53 (66%) of the symptomatic patients after the surgery. On the other hand, TMJ signs and symptoms appeared postoperatively in 7 (15%) of 47 patients without those before treatment. Psychologically, 42 patients noted favorable changes in personality after the surgery. Eight patients with mandibular set back noted the onset or worsening of snoring after the surgery.
