Facial anatomy
Published in Michael Parker, Charlie James, Fundamentals for Cosmetic Practice, 2022
The mandible is the jawbone (Figure 3.6), and it articulates with the temporal bone at the temporomandibular joint, allowing us to open and close the mouth at our leisure. It is found directly inferior to the maxilla and offers a point of anchorage of our lower teeth. The mandible is a complex bone with multiple discernible anatomical segments, including the body, angle, ramus, condyle and coronoid process. The area at which the two halves of the mandible fuse during development is known as the symphysis menti, located in the midline of the chin. The mandible has two main foramina on each side, the mandibular and mental foramina. The mandibular foramina are located in the middle of each mandibular ramus, and the mental foramina are located just lateral to the chin bilaterally. The mental foramina are of key clinical significance regarding augmentation of the chin with dermal fillers, as with any other facial foramina, due to the risk of avascular necrosis, filler embolisation and neuronal damage of structures exiting them.

The first part of the maxillary artery gives off the: inferior alveolar arterymiddle meningeal arteryaccessory meningeal arterydeep auricular arteryanterior tympanic artery. The inferior alveolar artery passes down to join the inferior alveolar nerve and enter the mandibular foramen. The MMA passes straight up through the foramen spinosum, while the accessory meningeal artery passes through the foramen ovale. The deep auricular artery passes up to supply the external auditory canal and the anterior tympanic artery enters the petrotympanic fissure on its way to the middle ear.

O'Carroll and Jackson classified SP ossification into four types on the basis of the location of the ossified SP: (a) both sides higher than the mandibular foramen; (b) both sides on the same level as the mandibular foramen; (c) both sides lower than the mandibular foramen; (d) unilateral or different lengths on the two different sides (16). In addition, Hardy et al. (14) found an unusual unilateral complete ossification of the stylohyoid apparatus that was always associated with laryngeal and vertebral calcifications.
