Less commonly, infections of the masticator space may be an extension of an infection arising in the parotid or submandibular glands or a tonsillar abscess [ 3 ]. Newman mh jr, emley we. Masticator space anatomy and pathologic conditions are illustrated examples from computed tomography and magnetic resonance imaging.
Deep Neck Infections
The masticator space is situated laterally to the medial pterygoid fascia and medially to the masseter muscle.
Masticator space malignancy or infection can spread perineurally via the foramen ovale and along the course of the mandibular division of the trigeminal nerve into the middle cranial fossa.
Removal of 4 mandibular and maxillary wisdom teeth. Once a submasseteric space infection is diagnosed, the key first step in resolving the infection is surgical evacuation of the pus4,5. The article describes infection, primary neoplasm, metastatic disease,. •seventy to 85% of these cases are odontogenic in origin, the rest are caused by sialadenitis, lymphadenitis, floor of mouth lacerations or mandible fractures.
Trismus often complicates evaluation of masticator space disease.
Masticator space abscess without dental procedure is an uncommon infection and. Consists of 4 contiguous potential spaces bounded by the muscles of mastication: It is bounded by the sphenoid bone, the posterior aspect of the mandible, and the. Ten patients had infection and 15 had tumor.
There are inflammatory changes with fat stranding within the left masticator space with swelling of the left masseter and buccinator muscles.
Pathology of this space has been clinically difficult to diagnose and treat. There is no further extent into the lower neck or upper mediastinum. Limited use when imaging the masticator space There is also swelling and stranding of the subcutaneous fat of the left.
Bacteria gain entry to the space from :
Characteristic imaging features of various disease processes are presented to aid the otolaryngologist (head and neck surgeon) in diagnosis. Masticator space anatomy and pathologic conditions are illustrated examples from computed tomography and magnetic resonance imaging. Characteristic imaging features of various disease processes are presented to aid the otolaryngologist (head and neck surgeon) in diagnosis. The buccal space is a deep facial space lying adjacent to the maxillary alveolar ridge.
However, computed tomography (ct) clearly delineates the normal and pathologic anatomy of this.
Masseteric, superficial temporal, deep temporal, pterygomandibular. Imaging of the buccal space by: The masticator space is a distinct deep facial space, bounded by the superficial layer of deep cervical fascia and containing the four muscles of mastication and the ramus and posterior body of the mandible. Although it is possible and occasionally more practical to drain the submasseteric space intraorally, sometimes it may be more prudent to gain access via an extraoral approach 6.
The left parapharyngeal space remains intact and there is normal appearance of the left medial pterygoid.
Imaging of buccal space 1. Occasionally, masticator space infection is secondary to malignant otitis externa often seen in diabetics or immunologically compromised patients. Infections of the masticator space are more frequent than tumours and are frequently odontogenic in origin (i.e., tooth extraction, caries with severe gingivitis, etc.). The left mandibular wisdom tooth socket is presumably the source of.
The deep neck space infections.
Trismus often complicates evaluation of masticator space disease. Here we report two cases of masticator space abscesses spreading from infections of mandibular teeth. The masticator space is a distinct deep facial space, bounded by the superficial layer of deep cervical fascia and containing the four muscles of mastication and the ramus and posterior body of the mandible. The imaging findings in 30 patients (ct in 30, mr in 16 patients) were retrospectively analysed.
It has been previously defined in anatomic studies performed to delineate the.
These areas are most often secondarily involved sites in several common inflammatory conditions such as dental abscess ( chapter 97 ); Propagation of odontogenic masticator space abscesses is insufficiently understood. Masticator space infections epidemiology the majority of masticator space i nfections are secondary to odontogenic infections. •ludwig’s angina is the prototypical submandibular space infection, however this term should not be applied to all submandibular abscesses.
Jaw swelling and trismus after a dental procedure are the typical clinical manifestations of a masticator space abscess in adults4,5).
Masticator space abscess represents an advanced stage of a commonly odontogenic infection indicated by buccal pain, swelling and trismus3). The article describes infection, primary neoplasm, metastatic disease. Ct was influential in directing appropriate biopsies or therapy in 24 of 25 patients. The purpose was to analyse pathways of spread in 30 patients with odontogenic masticator space abscess.
The masticator space (ms), buccal space (bs), and infratemporal fossa (if) are discussed in this chapter as the sites of origin for inflammatory, and almost always infectious, conditions of the head and neck.
