Description

We successfully used an endoscope to assist in the repair of mandibular condylar fractures in 12patients from August 2006 through October 2007. Their ages ranged from 16 to 68 years, with an average of 35years. All patients presented with unilateral condylar fractures. Seven of the 12 patients additionally had mandibularfractures.<br>A 4.0-mm, 30-degree angled endoscope was introduced to visualize the fracture site by means of an intraoralincision over the ascending ramus. A 2.0-mm titanium miniplate and screws were used to stabilize the fracture sitewith the help of a percutaneous trocar. The use of an angled endoscope provided a good view of the fracture site,permitting precise anatomical reduction.<br>All patients had a stable occlusion in the postoperative period, and anatomic alignment of the condyle was confirmedradiographically. There was no persistent facial palsy.<br>The benefits of using this endoscopically assisted technique include not only the provision of better visualizationand precise anatomic alignment of bony segments, but also the avoidance of facial nerve injuries and largefacial scars.
