The pterygomandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the head and is paired on each side. It is located between the medial pterygoid muscle and the medial surface of the ramus of the mandible .
In the head and neck, potential spaces are primarily defined by the complex attachment of muscles, especially mylohyoid, buccinator, masseter, medial pterygoid, superior constrictor and orbicularis oris. [6] Infections involving fascial spaces of the head and neck may give varying signs and symptoms depending upon the spaces involved.
The pterygomandibular raphe is a tendinous band [2] [3] formed by the buccopharyngeal fascia. It is a paired structure, with one on each side of the mouth. [ 3 ] Superiorly, it is attached to the pterygoid hamulus of the medial pterygoid plate of the sphenoid bone ; inferiorly, it is attached to the posterior end of the mylohyoid line of the ...
The boundaries of each submasseteric space are: the anterior margin of the masseter muscle anteriorly, the parotid gland posteriorly, [1]; the zygomatic arch superiorly, [1] the inferior border of the mandible inferiorly, [1]
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
The deep temporal space is one of the four compartments of the masticator space, along with the pterygomandibular space, the submasseteric space and the superficial temporal space. [1] The deep temporal space is separated from the pterygomandibular space by the lateral pterygoid muscle inferiorly and from the superficial temporal space by the ...
The mylohyoid line is a bony ridge on the internal surface of the body of the mandible.The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus.
The pterygoid hamulus is the superior origin of the pterygomandibular raphe. ... text in the public domain from page 151 of the 20th edition of Gray's Anatomy (1918)
