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 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.
