The purpose of this study is to examine pre- and postoperative self-evaluation of the face in jaw deformity patients, and to determine its differences between patient and doctor, using a specially prepared questionnaire.
The subjects were 20 mandibular prognathism patients (11 males and 9 females) who underwent orthognathic surgery in our department clinic, and their 20 orthodontists. The questions consisted of the following five items:(1) preoperative recognition of facial deformity, (2) self-evaluation of facial components in the preoperative stage, (3) expectation of facial change in the preoperative stage, (4) postoperative recognition of facial change, (5) selfevaluation of facial components in the postoperative stage. The answer for each question was graded. Characteristics of facial evaluation in male and female patients were statistically analyzed. The accordance ratio of facial evaluation between patient and doctor was also examined.
The results were as follows:
1. In both male and female patients, the preoperative recognition of facial deformity showed high ratings for the facial outline, mandible, and occlusion, and besides these areas, in female patients it also showed a high rating for the chin. The accordance ratio between doctors and female patients was generally high for all facial parts, while in male patients it was low for the chin and the upper and lower lips.
2. In the self-evaluation of facial components in the preoperative stage, male patients showed a significantly low rating for occlusion, and female patients for the mandible and occlusion. Both male and female patients showed high accordance ratios with their doctors for all facial parts.
3. In the expectation of facial change in the preoperative stage, the ratios of male patients were significantly high for occlusion, the mandible, and facial outline, and the ratios of female patients were high for occlusion and the mandible. For occlusion and mandible, both male and female patients showed high accordance ratios with their doctors.
4. In the postoperative recognition of facial change, both male and female patients showed significantly high ratings for facial outline, the mandible, and occlusion. The accordance ratio between doctors and female patients was generally high for all facial parts, while in male patients it was low for the chin and the lower lip.
5. In the self-evaluation of facial components in the postoperative stage, both male and female patients showed high ratings for all facial parts. The accordance ratio between doctors and female patients was generally high for all facial parts, while in male patients it was low for the cheek and the upper and lower lips.
