The cause is believed to be muscle tension or spasms within the affected musculature. [1] Diagnosis is based on the symptoms and possible sleep studies. [1] Treatment may include pain medication, physical therapy, mouth guards, and occasionally benzodiazepine. [1] It is a relatively common cause of temporomandibular pain. [1]
The term "trigger point" was coined in 1942 by Dr. Janet Travell to describe a clinical finding with the following characteristics: [citation needed]. Pain related to a discrete, irritable point in skeletal muscle or fascia, not caused by acute local trauma, inflammation, degeneration, neoplasm or infection.
Facioscapulohumeral muscular dystrophy (FSHD) is a type of muscular dystrophy, a group of heritable diseases that cause degeneration of muscle and progressive weakness. Per the name, FSHD tends to sequentially weaken the muscles of the face, those that position the scapula, and those overlying the humerus bone of the upper arm.
The platysma muscle is a broad sheet of muscle arising from the fascia covering the upper parts of the pectoralis major muscle and deltoid muscle. Its fibers cross the clavicle, and proceed obliquely upward and medially along the side of the neck. This leaves the inferior part of the neck in the midline deficient of significant muscle cover.

The pain from these contractions can cause mobility limitations and a tense feeling within the muscle, he says. While they’re usually harmless, muscle cramps are undoubtedly uncomfortable.
The 42nd edition of Gray's Anatomy (2020) describes a parotid-masseteric fascia as a thin and translucent yet tough fascia that covers the parotid duct, buccal branches of facial nerve (CN VII), and branches of the mandibular nerve where these structures lie upon the surface of the masseter muscle. Anteriorly, the fascia is said to overlie the ...
The deep cervical fascia (or fascia colli in older texts) lies under cover of the platysma, and invests the muscles of the neck; it also forms sheaths for the carotid vessels, and for the structures situated in front of the vertebral column. Its attachment to the hyoid bone prevents the formation of a dewlap. [1]
The muscles of mastication are enclosed in a layer of fascia, formed by cervical fascia ascending from the neck which divides at the inferior border of the mandible to envelope the area. Each masticator space also contains the sections of the mandibular division of the trigeminal nerve and the internal maxillary artery .
