Intraoral approach to condyle

Protecting the nerve

Sensory buccal nerve
The sensory buccal nerve crosses the upper anterior rim of the mandibular ascending ramus in the region of the coronoid notch. It is usually below the mucosa running above the temporalis muscle fibers. When the posterior vestibular incision is carried sharply along the bony rim, the buccal nerve is at risk of transsection resulting in numbness in the buccal mucosal region. Therefore, to protect the nerve, the posterior incision is to be extended bluntly as soon as the lower coronoid notch is reached.
