La voie d'abord sous-angulo-mandibulaire en dehors de la traumatologie

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.
