The pterygomandibular ligaments are marked with arrows. Note that in this mouth the lower wisdom teeth have been removed, slightly changing the shape of the pterygomandibular ligaments that usually curve and attach to the mandible around them. The pterygomandibular raphe is a tendinous band [2] [3] formed by the buccopharyngeal fascia.
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 .
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]
This term is sometimes used, and is a collective name for the submasseteric (masseteric), pterygomandibular, superficial temporal and deep temporal spaces. The infratemporal space is the inferior portion of the deep temporal space. The superficial temporal and the deep temporal spaces are sometimes together called the temporal spaces.
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 sites of origin of the muscles collectively are the pterygoid hamulus (and occasionally the adjoining posterior margin of the medial pterygoid plate) anteriorly, (the posterior margin of) the pterygomandibular raphe, the posterior extremity of the mylohyoid line of mandible, and (negligibly) the side of the tongue.
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 ...
