Abstract

There is limited literary knowledge about masticatory functional efficiency post-intervention in patients with panfacial trauma. The aim was to evaluate the masticatory functional efficiency of the stomatognathic system in patients with panfacial fractures preoperatively and postoperatively. This prospective study had two groups. Group 1 (n=20) consisted of patients with panfacial fractures. Group 2 (n=20) consisted of healthy volunteers. Mean Maximum Voluntary Bite Force (MVBF) of the Group 1 was recorded. Preoperative MVBF of Group 2 subjects was recorded. Postoperatively the MVBF was recorded in Group 2 subjects at 1 week, 1 month, 3 months and 6 months. Group 2 subjects were asked to answer a pre-validated, modification of OHIP-14 questionnaire 6 months postoperatively. It was concluded that patients regained masticatory functional efficiency comparable to that of normal healthy volunteers by 6 th postoperative month with significant improvement in quality of life. Intraoperative factors such as amount of periosteal bone stripping and number of muscle attachments released can have a negative impact on the patients’ masticatory efficiency in the long run.
