Jaw resection

The mandible provides a bony framework to hold the teeth and sensation to the lip and chin is provided by the inferior alveolar nerve which enters at the mandibular foramen and exits at the mental foramen. Although there are often attempts to preserve this nerve in the treatment of benign disease, the loss of sensation to the lip and chin is an acceptable morbidity for most patients. The relationship of the teeth to the bone varies with patients and the molars run from a buccal position to a more lingual position posteriorly. The temporomandibular joint articulates with the skull base and in some cases the condylar head may require resection. The loss of teeth results in the loss of the supporting alveolar bone. The inferior alveolar nerve will come to lie on the alveolar ridge and the relationship of the floor of mouth muscle insertions will alter with the loss of bone (Figure 39.1 and 39.2).

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.

Are the following statements regarding the jaw true or false? The inferior alveolar nerve exits the mandible via the mandibular foramen.The temporalis muscle is innervated by the maxillary branch of the trigeminal nerve.Computed tomography (CT) scan is indicated to assess the alveolar process anatomy before placement of dental implants.Mandibular fractures tend to be orientated perpendicular to the long axis of the roots of the teeth.Taste fibres from the anterior two-thirds of the tongue are carried in the chorda tympani nerve.

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.
