Masticator space

The masticator space is bounded by the fascia overlying the masseter muscle, medial pterygoid muscle, temporalis muscle, and the skull. The superficial and deep temporal spaces are separated from each other by the temporalis muscle. The lateral pterygoid muscle divides the pterygomandibular space from the infratemporal portion of the deep temporal space, and the zygomatic arch divides the submasseteric space from the superficial temporal space.
