Exposure of the temporomandibular joint and/or mandibular condyle/ramus
The temporomandibular joint and the upper portion of the ascending ramus of the mandible are also accessible through the extended coronal incision.
The dissection proceeds below the zygomatic arch. First, the deep part of the masseter muscle is stripped from its origin at the posterior end of the arch to expose the lateral surface of condylar process above the joint capsule and the periosteal coverage of the condylar neck inferior to the capsular fiber insertions.
Stripping of the periosteum allows access to the anterior lateral and posterior bony surfaces of the condylar neck.
Strict subperiosteal dissection and soft-tissue retraction over the condylar neck inferiorly moves the facial nerve trunk and its branches out of the surgical field as demonstrated.
The temporomandibular joint is not yet entered.
