“…The majority of authors describe a vertical incision starting at the mastoid process and running parallel to the SCM muscle, 1 , 3 , 9 - 12 , 15 , 17 , 21 , 30 , 31 , 33 , 36 , 40 , 48 , 52 , 53 enabling exposure of the great auricular nerve, the mastoid process, and the retromandibular fossa. 11 Pre-auricular extensions are also described, 4 , 9 , 37 offering the advantage of facilitating identification of the facial nerve. When mandibular osteotomies (MDO) are planned, incisions can be extended along the submandibular and submental regions and the lower lip.…”
