This questionnaire survey was performed to evaluate the course after the surgical correction of the mandibular prognathism. The objects were 47 out of 70 patients who were treated by saggital ramus split osteotomy of the mandible. Especially, temporomandibular joint symptoms after surgical correction were examined with the conclusions as follows.
1. Disturbance of the temporomandibular joint before surgery was seen in 12 out of 47 patients. 7 patients in the 12 had no temporomandibular joint symptoms after surgery.
2. An oppressive pain of the temporomandibular joint after surgery was found in 5 out of 47 cases (10.6%).
3. Six patients had an opened mouth of 2 finger width after surgery (12.8%).
4. Six patients (12.8%) answered “It doesn't move as easily as before surgery” on the lateral movement of the mandible after surgery. Two patients (4.3%) answered “It doesn't move as easily as before surgery” on the anterior movement of the mandible after surgery.
5. Temporomandibular joint symptoms after surgery were found in 11 patients (23.4%) on the opening and closing movement, 13 patients (27.7%) on the lateral movement, 5 patients (10.6%) on the anterior movement of the mandible.
6. Ten out of sites were all dull painful, indicating a temporomandibular joint pain after surgery.
7. Four out of the 16 patients had a sound which a surrounding people could recognize well, indicating a temporomandibular joint sound after surgery.
