[Anatomical and functional studies on surgical and non-surgical treatment of mandibular condylar process fractures].
OBJECTIVE
This study aim at comparing anatomical and functional recovery from surgical and non-surgical treatment of condylar process fractures.


METHODS
Totally Forty-nine patients, 22 treated by performing operation, and 27 using non-surgical methods, were included in this study. Displaced angle of condylar, maximal mouth opening, lateral deviation on opening and masticatory function were analyzed using radiological and clinical examinations 6 weeks and 1 year after treatment.


RESULTS
Patients treated by surgical method had significantly greater initial displaced angle of condyles than did the group treated non-surgically, but patients treated non-surgically had significantly greater displaced angle of condylar and lateral deviation on opening than did the group treated surgically 6 weeks and 1 year after the therapy finished. Patients treated surgically had significantly greater masticatory function than did the group treated non-surgically 6 weeks and 1 year after treatment. Six weeks later, patients treated surgically had significantly greater maximal mouth opening than did the group treated non-surgically.


CONCLUSIONS
Surgical treatment may be helpful in anatomical and functional recovery of mandibular condyles for patients with displaced condylar process fractures.
