What are masticator spaces?
The masticator spaces are paired supra-hyoid cervical spaces on each side of the face that extend from the angle of the mandible to the parietal calvarium [1]. The masticator space contains the mastication muscles, posterior mandible, and mandibular nerve [3, 4].
Where is the masticator space located?
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. It lies inferiorly to the temporal space and is anterolateral to the parapharyngeal space.
What is Masseteric space?
The submasseterric space (also termed the masseteric 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 face over the angle of the jaw, and is paired on each side.
What is buccal space infection?
Buccal space infections – These arise primarily from mandibular or maxillary bicuspid or molar teeth, the apices of which lie outside of the buccinator muscle attachments. They are readily diagnosed because of marked cheek swelling but with minimal trismus or systemic symptoms (see Figure 4).
What is submandibular space?
The submandibular space is a suprahyoid deep compartment of the head and neck that encompasses the submandibular gland and surrounding structures.
How do you drain a deep temporal space infection?
[1] Temporal space infection presents as a swelling in the temporal region superior to the zygomatic arch and posterior to the lateral orbital rim [2, 3]. Usually, infections of the temporal space are drained via temporal approach within the hairline making a 45 degree angle to the zygomatic arch.
What is parotid space?
The parotid space is one of the deep compartments of the head and neck and, as the name suggests, is mostly filled with the parotid gland. It is the most lateral major suprahyoid neck space.
What is the buccal space?
The buccal spaces are paired fat-containing spaces on each side of the face forming cheeks. Each space is enveloped by the superficial (investing) layer of the deep cervical fascia. It is located between the buccinator and platysma muscles, therefore it is only a small potential space with limited contents.
What is Pterygomandibular space?
The pterygomandibular space (PM) is a space largely composed of connective tissue and muscle but also contains several neurovascular structures. It is triangular in shape and is bounded by the medial surface of the mandibular ramus laterally.
How do you treat buccal space infection?
The treatment of fascial space infections includes aggressive intravenous high dose antibiotics (usually penicillin or cephalosporins and metronidazole), analgesic and fluid therapy in addition to establishment of surgical drainage and elimination of the source of infection.
What is the masticator space?
he masticator space is a fascial space that can be invaded by tu- mors from adjacent structures or from hematogenous metastases. Tumor invasion of the masticator space usually upstages the original tumors. The secondary tumor may also extend intracra- nially from the masticator space along the neurovascular bundle. Trismus that com-
Does the masticator space appear on a CT scan?
The CT appearance of the masticator space was demonstrated in a retrospective review of 32 patients with either infection or tumor involving this space. Masticator space infections were found to have characteristic CT appearances and patterns of spread.
What is the pathophysiology of masticator space tumor invasion?
Tumor invasion of the masticator space usually upstages the original tumors. The secondary tumor may also extend intracranially from the masticator space along the neurovascular bundle. Trismus that commonly accompanies masticator space involvement often makes physical examination difficult. CT and MRI can clearly delineate the extent of the tumor.
What is a secondary tumor of the masticator?
Tumor invasion of the masticator space usually upstages the original tumors. The secondary tumor may also extend intracra- nially from the masticator space along the neurovascular bundle. Trismus that com- monly accompanies masticator space in- volvement often makes physical examina- tion difficult. CT and MRI can clearly
