Consists of 4 contiguous potential spaces bounded by the muscles of mastication: Exposure and drainage of the masticator space and contiguous structures through a modified blair preauricular and cervical incision was. Different neoplasms and infections are known to involve the masticator space, but pathological diagnosis and treatment of these lesions are not always simple due to anatomical complexity.
masticator space infections Imaging , clinical findings
Or hematoma of floor of mouth;
Infections here may be a result of dental infections, particularly of the third mandibular molars.
Masseteric, superficial temporal, deep temporal, pterygomandibular. Severe complications including mediastinitis, pericarditis and death have been reported. Infection of the masticator space can break through the fascia and involve the adjacent space. The purpose was to analyse pathways of spread in 30 patients with odontogenic masticator space abscess.
The masticator space is located between the masseteric fascia and the pterygoid muscle fascia.
Masticatory space there are 5 masticatory spaces. Masticator space infections were found to have characteristic ct appearances and patterns of spread. Physical and ct findings resembled those of neoplastic lesion because the onset dated back 5 years and. 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.
The masticator space is defined as the separate fascial compartment containing the pterygoid, masseter and temporalis muscles and the mandible1,2).masticator space abscess represents an advanced stage of a commonly odontogenic infection indicated by buccal pain, swelling and trismus3).jaw swelling and.
S ix cases of chronic masticator space infection associated with firm facial swelling and progressive trismus are described. Mgc carried out substantial contributions to conception, design, acquisition of data, analysis, interpretation of data and drafting the. The masticator space could therefore be described as a potential space with four separate compartments. Differential diagnosis for disease of the masticator space depends largely on consideration of the structures that normally occupy the space, with the exception of infection, which tends to be from odontogenic causes.
These areas are most often secondarily involved sites in several common inflammatory conditions such as dental abscess ( chapter 97 );
Intraoral wound drainage and prolonged antibiotic therapy failed to control the resultant chronic cellulitis. • noninfectious pathologic conditions may commonly involve neural structures, such as with schwannoma or perineural tumor spread. When a masseteric space infection is diagnosed, multiple space involvement is ruled out, and dependent drainage is required, this modified drainage technique can be useful. Removal of 4 mandibular and maxillary wisdom teeth.
Masticator space abscess derived from odontogenic infection:
The left mandibular wisdom tooth socket is presumably the source of infection. Infections usually only occupy one of these compartments, but severe or long standing infections can spread to involve the entire masticator space. The correct diagnosis and proper management are, therefore,. Here we report two cases of masticator space abscesses spreading from infections of mandibular teeth.
Propagation of odontogenic masticator space abscesses is insufficiently understood.
There is also swelling and stranding of the subcutaneous fat of the left side of the face. Ct was especially useful in differentiating inflammation from frank abscess, detecting mandibular osteomyelitis, and directing surgical drainage to. When inflamed, the muscles appear. Treatment the treatment for masticator space infection involves controlling the infection of the primary site.
There are inflammatory changes with fat stranding within the left masticator space with swelling of the left masseter and buccinator muscles.
Infection in the masticator space may spread to the parapharyngeal, parotid, or temporal space. 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. Newman mh jr, emley we. The vast majority of masticator space abscesses due to odontogenic disease consist of mixed infection.
Imaging manifestation and pathways of extension depicted by ct and mr in 30 patients.
Bacteria gain entry to the space from : The left parapharyngeal space remains intact and there is normal appearance of the left medial pterygoid. Masticator space abscess may also be due to malignant otitis externa with the most common organism being pseudomona;
