Tumor invasion of the masticator space usually upstages the original tumors. 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].
Biopsy of Head and Neck Lesions Radiology Key
It is separated from the adjacent face and neck spaces by a superficial layer of deep cervical fascia except superiorly, where it freely communicates with the external temporal fossa, which may be considered as an upper.
The secondary tumor may also extend intracranially from the masticator space along the neurovascular bundle.
Submasseteric abscesses are rare and are associated with marked trismus. The masticator space is situated laterally to the medial pterygoid fascia and medially to the masseter muscle. This is also referred to as the masseter space or the superifical masticator space. The masticator space is a deep facial space with a complex anatomical structure.
The article describes infection, primary neoplasm, metastatic disease,.
De l’anatomie à la pathologie}, author={n. Anatomy of the masticator space. Characteristic imaging features of various disease processes are presented to aid the otolaryngologist (head and neck surgeon) in diagnosis. Primary tumors are uncommon, usually benign and of a vascular or neural origin.
The masticator space is a fascial space that can be invaded by tumors from adjacent structures or from hematogenous metastases.
From anatomy to pathology espace masticateur : Tumor invasion of the masticator space usually upstages the original tumors. Intrinsic tumours of this space can be benign and malignant, and they may arise from the mandibular ramus, the third division of the trigeminal. 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
Of the mandibular ramus, enveloping the space [2, 3](fig.1).
The masticator space (ms) is a deep facial space which contains the mandibular ramus, muscles of mastication and the mandibular branch (v3) of the trigeminal nerve. Have tried to show muscles forming masticator space and also the subdivisions of this space. The masticator space is a deep facial space that is outlined by the superficial layer of the deep cervical fascia , , and lies laterally and evenly in front of the prestyloid space, medial to the pharyngeal space and beneath the skull base. The article describes infection, primary neoplasm, metastatic disease, osteonecrosis, and vascular.
Juvara first described this space while the first reference to ms was made by coller and yglesias.1 anatomy 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
Anatomic specimens were dissected to define better the fascial layer representing the medial wall of the masticator space. Masticator space anatomy and pathologic conditions are illustrated examples from computed tomography and magnetic resonance imaging. 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. The masticator space as an anatomical and functional entity centered on the mandibular ramus, which divides it into medial and lateral compartments.
A fascial layer was found extending from the medial pterygoid muscle to the skull base separating the masticator from the parapharyngeal space.
Primary tumors are uncommon, usually benign and of a vascular or neural origin. This article reviews and illustrates the anatomy and pathology of the masticator space (ms). The third branch of the. 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.
Each space is delineated by a superficial layer of the deep cervical fascia (sldcf).
The submasseteric space is logically located under (deep to) the masseter muscle, created by the insertions of masseter onto the lateral surface of the mandibular ramus. The masticator space (ms), buccal space (bs), and infratemporal fossa (if) are discussed in this chapter as the sites of origin for mass lesions of the head and neck. Masticator space anatomy and pathologic conditions are illustrated examples from computed tomography and magnetic resonance imaging. The masticator space is further subdivided into the following compartments:
Masticator space is formed superficial layer of the deep fascial surrounding loose connective tissue and fat pad along with the above structures.
From anatomy to pathology espace masticateur : Masticator space the ms is a term more familiar to the radiologist. Here, we report an unusual case of pa of left masticator space in a. The buccal space, also known as the buccinator space, is one of the seven suprahyoid deep compartments of the head and neck.
The masticator space is a deep facial space with a complex anatomical structure where pa is not known to occur.
The space is traversed by the mandibular nerve and internal maxillary vessels. The anatomy of the masticator space and its anatomic relationship with adjacent structures is important for imaging interpretation. Do let me know if you don’t understand anything and if you need. Pathology of the masticator space includes inflammatory conditions, vascular lesions, and tumours.

Characteristic imaging features of various disease processes are presented to aid the otolaryngologist (head and neck surgeon) in diagnosis. It may be affected by developmental, neoplastic or infectious lesions. The separation of the masticator and parapharyngeal spaces is somewhat ambiguous.
