The infratemporal fossa is the skull compartment localized below the temporal fossa and medial to the ramus mandibulae. The point which usually is missed out is that the pterygopalatine fossa is the part of the fossa infratemporalis. Therefore the infratemporal fossa is directly bordered ( temporal fossa & basis cranii externa) or connects via

Mandibular fossa: on the skull, the concave part of the hinge joint for the jaw. The mandibular fossa is in the temporal bone, and the joint is called the temporomandibular joint . Angular process: an attachment point for the masseter muscle, which (along with the temporalis) helps in biting and chewing.

The temporal fossa should be palpated in the neutral position and with the teeth clenched to assess muscle bulk. The range of motion of the mandible should also be determined. Trismus may indicate fibrosis or scarring of the temporalis muscle further limiting its … The Infratemporal Fossa. This is an irregularly shaped space inferior and deep to the zygomatic arch and posterior to the maxilla.; It communicates with the temporal fossa through the interval between the zygomatic arch and the skull, which is traversed by the temporalis muscle … Middle Fossa Approach to the Internal Auditory Canal Extended Middle Fossa Approach to the Cerebellopontine Angle Combined Craniotomies: Posterior & Middle Fossae The zygomatic arch is an arch of bone on the lateral aspect of the skull formed by the zygomatic process of the temporal bone and the temporal process of the zygomatic bone, united along the zygomaticotemporal suture. It provides passage of the temporalis muscle, auriculotemporal nerve, zygomatic and temporal branches of the facial nerve. sits atop the condyle and fills the mandibular fossa above when the mandible is at rest.

Anatomynote.com found Temporal Lob Of Skull Anatomy from plenty of anatomical pictures on the internet. Temporalis muscle retraction may be performed in two ways: superiorly or inferiorly. Superior retraction after resection of mandibular coronoid process provides the widest exposure of the infratemporal fossa, but at the expense of denervation and devascularization of the temporal muscle.

The infratemporal fossa is an irregularly shaped cavity, situated below and medial to the zygomatic arch. It is not fully enclosed by bone in all directions, and it

Therefore the infratemporal fossa is directly bordered ( temporal fossa & basis cranii externa) or connects via temporal fossa an area on the side of the cranium bounded posteriorly and superiorly by the temporal lines, anteriorly by the frontal and zygomatic bones, and laterally by the zygomatic arch, lodging the temporal muscle.

The medial extent of the skull base defect appears to be a limiting factor in the utilization of this ﬂap. Bilateral pedicled temporalis ﬂap has been used to reconstruct the palate and frontal sinus defects,10,11 but weare yet toutilize it for repairing total skull base defects.

The infratemporal fossa is a complex area located at the base of the skull, deep to the masseter muscle.. It is closely associated with both the temporal and pterygopalatine fossae and acts as a conduit for neurovascular structures entering and leaving the cranial cavity.. This article will outline the borders and content of the fossa before examining its clinical relevance.
