Summary:To investigate the influence of mandibular curved osteotomy on masticatory function by analyzing the bite force before and after operation. From Jan. to Oct. 2008, 20 female cases underwent mandibular curved osteotomy. The maximal bite force in incisor area, bilateral premolar area and molar area was measured before operation and 6 months after operation. The maximal bite force in incisor area, right premolar area, left premolar area, right molar area, left molar area was (11.7 +/- 3.9) kg, (23.2 +/- 1.6) kg, (30.9 +/- 2.3) kg, (35.6 +/- 4.2) kg, (38.5 +/- 3.1) kg, respectively before operation; and was (11.9 +/- 2.1) kg, (23.0 +/- 4.5) kg (31.0 +/- 1.8) kg,(35.9 +/- 3. 5) kg. (38.5 +/- 2.7) kg, respectively 6 months after operation. The postoperative maximal bite force reached the preoperative level, and even slightly above it. There was no significant difference between the measured data before operation and 6 months afterward (P > 0.05). The curved osteotomy of prominent mandibular angle has no long-term e
