Part 1 - Parotid Area
Clean the superficial surface of the masseter m.
Completely remove the parotid gland while preserving the neurovasculature in this region
Part 2 - Muscles of Mastication
Separate the temporalis m. from the zygomatic arch and the masseter m.
Relieve the masseter m. from its proximal attachments and reflect inferiorly
Cut through the zygomatic process of the temporal bone, just anterior to the articular tubercle of the temporal bone
Relieve the zygomaticus major m. from its attachment to the zygomatic bone
Relieve the deep part of the masseter m. from the zygomatic arch, and remove the zygomatic arch
view the buccal fat pad and the inferior attachment of the temporalis m. to the coronoid process of the mandible
Remove the buccal fat pad and clean the superficial aspect of the buccinator m.
Clean the temporal fascia to reveal the tendon and belly of the temporalis m.
Locate the mandibular notch, and locate portions of the masseteric n. and a.
Palpate the styloid process of the temporal bone. Locate the stylomandibular ligament
Part 3 - Infratemporal Fossa
Cut the base of the coronoid process of the mandible, and superiorly reflect the coronoid process and temporalis m.
Locate the lateral ligament of the temporomandibular joint covering the condylar process of the mandible
Cut through the base of the condylar process of the mandible adjacent to the mandibular notch
Locate the inferior alveolar neurovascular bundle, and follow it inferiorly to the mandibular foramen
Cut the ramus of the mandible at or just above the mandibular foramen
Locate the vascular supply (anterior & posterior deep temporal aa. & vv.) and innervation (deep temporal nn.) for the temporalis m.
Part 4 - TMJ
Examine the temporomandibular joint (TMJ)
Manipulate the condylar process to appreciate the motions possible at this joint
Clear the lateral ligament from the joint capsule
Remove the lateral aspect of the joint capsule to reveal the articular disc and the upper and lower synovial cavities
Part 5 - Pterygoid Muscles
Identify the maxillary a., but do not dissect/identify its branches at this time
Clean the lateral pterygoid m. and medial pterygoid m.
Distinguish between the superior and inferior heads of the lateral pterygoid m.
