Figure 1 shows that the four mastication muscles are the medial and lateral pterygoids, masseter, and temporalis [ 3 , 4 ]. It lies inferiorly to the temporal space and is anterolateral to the parapharyngeal space. It lies inferiorly to the temporal space and is anterolateral to the parapharyngeal space.

The cardinal mandibular movements of mastication are elevation, depression, protrusion,.
Figure 1 shows that the four mastication muscles are the medial and lateralpterygoids,masseter,andtemporalis[3,4].thelateral pterygoid muscle, the only muscle lying within the space

Ct and mr imaging depicted a masticator space abscess within: Unlike the itf it is clearly a fascia enclosed space.
It is bounded by the sphenoid bone, the posterior aspect of the mandible, and the zygomatic arch.
These include the masticator, temporalis, the medial and lateral pterygoids. Mr and ct findings in 46 cases with proven masticator space lesions were reviewed retrospectively. The masticator space (ms) contains muscles of mastication (medial and lateral pterygoid, masseter, and temporalis), ramus of the mandible and the third division of the cranial nerve v (figure 10a). Masticator space is formed superficial layer of the deep fascial surrounding loose connective tissue and fat pad along with the above structures.
The muscles of mastication are enclosed in a layer of fascia, formed by cervical fascia ascending from the neck which divides at the inferior border of the mandible to envelope the area.
Medial pterygoid muscle in 13 patients (43.3%), lateral masseter and/or pterygoid muscle in 14 (46.7%) and superficial temporal muscle in 3 patients (10%). Salivary gland tumors can also extend into this space. Diffuse abnormal enhancement of the masseter and pterygoid muscles adjacent to the osseous changes in the mandible was noted in all five patients when compared with the contralateral nonenhancing normal masticator muscles. Air was seen in the masticator space of a patient who developed a cutaneous fistula.
Of the mandibular ramus, enveloping the space [2, 3](fig.1).
This space contains the muscles of mastication. Correspondingly, where is the masticator space? The space is traversed by the mandibular nerve and internal maxillary vessels. The ms as the name implies consists of the masticator muscles (medial and lateral pterygoid, temporalis and masseter) and the posterior body and ramus of the mandible along with the mandibular nerve and the internal maxillary artery.
We analysed the involvement of masticator muscles, adjacent spaces, orbit and intracrahium, homogeneity, necrosis, cystic changes, growth patterns, calcifications, enhancement patterns, mr signal intensity, and ct attenuation.
Metastatic extensions of squamous cell carcinoma, particularly from the floor of the mouth, tonsilar fossa, and nasopharynx can be found extending into this space. Masticator muscles url of article the muscles of mastication can be divided into primary and secondary groups according to whether they connect the mandible directly to the skull or if they attach to other structures in the neck, e.g. The primary muscles of mastication (chewing food) are the temporalis, medial pterygoid, lateral pterygoid, and masseter muscles. The masticator space contains the mastication muscles, posterior mandible, and mandibular nerve [3, 4].
Nose, paranasal sinuses, face, and oral cavity keywords:
The purpose of the present study was to precisely define the masticator space to eliminate the use of obsolete and confusing terms to describe the area, and to illustrate the common mass syndromes. It is bounded by the sphenoid bone, the posterior aspect of the mandible, and the. The masticator space (ms) is a deep facial space delineated by a splitting of the deep cervical fascia which encloses the four muscles of mastication: This space is located anterolateral to the pps (fig.
Primary tumors are uncommon, usually benign and of a vascular or neural origin.
Each masticator space also contains the sections of the mandibular division of the trigeminal nerve and the internal maxillary artery. The masticator space is situated laterally to the medial pterygoid fascia and medially to the masseter muscle. It is bounded by the sphenoid bone, the posterior aspect of the mandible, and the zygomatic arch. Inferior alveolar artery, vein and nerve;
Figure 1 shows that the four mastication muscles are the medial and lateral pterygoids, masseter, and temporalis [ 3 , 4 ].
The masticator space is situated laterally to the medial pterygoid fascia and medially to the masseter muscle. Masticator muscle tumor infiltration epidemiology malignancies originating in spaces and structures adjacent to the masticator space can involve the masticator muscles. Mandibular (v3) and maxillary (v2) branches of the trigeminal nerve (cranial nerve v) source: A simplified approach to the spaces of the suprahyoid neck
The masticator space is situated laterally to the medial pterygoid fascia and medially to the masseter muscle.
The masticator space contains the mastication muscles, posterior mandible, and mandibular nerve [3, 4]. The four main muscles of mastication attach to the rami of the mandible and function to move the jaw (mandible). Mouth, magnetic resonance created date:. Masticator muscle enhancement in subacute denervation atrophy author:
The enhancement was intense in.
Four muscles of mastication (masseter, medial and lateral pterygoids, and temporalis) ramus and posterior portion of the body of the mandible; Nasopharyngeal carcinoma frequently spreads into the masticator space to involve principally the medial pterygoid muscle. The masticator space is a deep facial space with a complex anatomical structure. The masticator space contains the mastication muscles, posterior mandible, and mandibular nerve [3, 4].
