| Research Abstract |
Square mandible is characterized by severe limitation of mouth opening. This study aimed to clarify the etiology of Square mandible with the "4-D Muscle Model". We applied this system to the 18 patients of Square mandible. From the results, the expansion rates of temporal muscles in the patient were less than those in the control. Moreover, in all cases, the limitation of mouth-opening was remarkably improved by surgical treatment according to the analysis result. The main cause of limitation of mouth-opening was suggested to be a contracture of the temporal muscle. The present "4-D muscle model" would be valuable tool to decide the target muscle of surgical treatment for patients with Square mandible.
