Recently, we have used internal fixation with tuanium miniplate which introduced by Champy in 1976 in facial bone fractures. In cases of mandibular fractures, particulary mandibular angle fractures, we usually underwent the open reduction
extraorally,
But extraoral approaches may leave scars and put the facial nerve at greater risk.
So, we had undergone the intraoral approaches in 31 patients of mandibular angle fractures (male: 29, female: 2). These patients visited in Wonkwang university hospital from October 1991 to June 1993. We got easy operation time as average 20
minutes
than extraoral approach. And reduced the postoperative nerve injury (14.2%), but postoperative infection is 6.1% nearly as same as extraoral approach. TMJ problems after intraoral open reduction was similar to extraoral approaches.
