[Modified Risdon approach for non-traumatic ramus surgery].
BACKGROUND
The Risdon modified approach, for mandibular surgery, is well adapted to treatment of low subcondylar fractures. According to our experience, this approach with a low rate of complications should also be considered for non-traumatic ramus surgery.


METHODS
Twenty Risdon modified approaches were used in 11 patients for non-traumatic indications (seven bilateral osteotomies, four unilateral osteotomies, one biopsy, one bone graft). One patient was operated twice with the same approach.


RESULTS
In all cases, the planned surgery could be performed using this approach. The only complication was a case of temporary paresis of the facial nerve's mandibular branch. The scar was always considered as quite acceptable.


CONCLUSIONS
As for traumatology, the Risdon modified approach is an improvement for ramus non-traumatic surgery. It has a very low rate of complications, especially for the facial nerve. The intraoral approach avoids scarring, but the resulting exposure is insufficient and requires using a transcutaneous device or endoscopy. In orthognathic surgery, the wide exposure of the lateral aspect of the ramus, the corpus, and the basilar edge, facilitates important mandibular advancement.
