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 .
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 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 ...
Diagram showing lateral surface of the mandible and the area of insertion of the masseter muscle on the mandibular ramus. The left masseter muscle (red highlight), shown partially covered by superficial muscles such as the platysma muscle , the zygomaticus major muscle and the zygomaticus minor muscle
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 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.
His death came just a couple of weeks after Leo Lukenas, 35, who was in the bank’s investment banking group in New York City, died of an acute coronary artery thrombus, according to the New York ...
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.
