Masseter space infection

Introduction to masseter muscle infection Masseter muscle interstitial infection refers to purulent infection in the masseter muscle space. The main clinical manifestation is acute inflammatory redness, tenderness and tenderness centered on the chewing muscle. In the case of masseter muscle cellulitis, in addition to systemic application of antibiotics, local physiotherapy or topical Chinese medicine can be applied locally. Once the abscess is formed, it should be drained in time. basic knowledge The proportion of illness: 0.002%-0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: swelling

Causes of masseter muscle gap infection

The masseteric space is located between the masseter muscle and the lateral wall of the mandibular ascending branch. Because the masseter muscle is widely attached to the mandibular branch and its horn, the potential masseteric space exists in the lateral part of the upper segment of the mandibular ascending branch. Fat connective tissue is connected to the cheeks, underarms, pterygoids, and sacral space. The masseteric space is one of the most common infections of the maxillofacial space.

Masseter muscle infection prevention

The infected tooth should be treated or removed as soon as possible.

1, acute serum period: early on the principle of anti-inflammatory.

(1) In addition to systemic symptomatic treatment, anti-inflammatory and analgesic drugs such as antibiotics, sulfonamides and analgesics are used.

(2) External application of golden powder, fish stone fat ointment, etc.

(3) Physical therapy: ultraviolet light, infrared light, etc.

2, acute suppuration

The drainage should be cut in time. If the delay is self-destruction, the face is left with obvious scars, otherwise the fascial space is not broken and the course of the disease is deteriorated.

3. Remove the diseased teeth after the inflammation subsides.

4. Actively carry out the prevention and treatment of dental caries, remove the diseased teeth, and timely treat acute glandular tissue inflammation and facial jaw spasm and traumatic infection.

Masseter muscle infection complications Complications swelling

It may be accompanied by swelling of the ankle, the masseter muscle area of the parotid gland, the buccal and intraoral maxillary nodule area, and the corresponding symptoms of the combined gap infection.

Masseter muscle interstitial infection symptoms Common symptoms Edema masticatory muscle hypertrophy ankle pain

History

There is a history of acute suppurative mandibular wisdom tooth pericoronitis.

2. Clinical manifestations

Acute inflammatory redness, tenderness and tenderness centered on the chewing muscles, over the range of redness and swelling above the zygomatic arch, lower jaw, anterior to cheek, posterior to the posterior region, deep depression with depressed edema, not easy to smash Dynamic, with severe open restriction, use a thick needle to puncture from the red and swollen center. When the needle tip reaches the bone surface, pull back and slowly withdraw the needle to get a little sticky pus. The patient has high fever, the total number of white blood cells is increased, and the proportion of neutrophils is increased. Big.

The position of the inferior temporal space is deep and concealed, so the appearance of infection is often not obvious when the infection occurs. Careful examination reveals that the upper and lower jaws of the zygomatic arch are slightly swollen, with deep tenderness, with varying degrees of mouth opening, but Infection of adjacent gaps often occurs in the inferior interstitial infection, and may therefore be accompanied by swelling of the ankle, parotid masseter, buccal and intraoral maxillary nodules, and corresponding symptoms of the combined interstitial infection.

Examination of masseter muscle infection

Blood routine examination: the total number of white blood cells increased, and the proportion of neutrophils increased.

Diagnosis and diagnosis of masseter muscle gap infection

To be differentiated from mumps and tonsillitis.

The onset of mumps is rapid, most patients have high fever, chills, general malaise, leukocytosis and other systemic symptoms, mostly occur on one side, the ipsilateral parotid area is red and swollen, the mandibular posterior recess disappears, the earlobe is upturned, due to the dense glandular capsule, swelling Constrained, the internal pressure is increased, so the pain is severe, the tenderness is obvious, and the strong mouth is limited. The affected side of the parotid duct is red and swollen, and there is purulent discharge. Due to the separation of the fascia, the abscess is often multiple. , scattered small pus, so there is no typical fluctuation in the early stage.

Tonsillitis includes systemic and local symptoms.

(A) systemic symptoms: acute onset, aversion to cold, high fever, up to 39 ~ 40 ° C, especially children can be convulsions due to high fever, vomiting or lethargy, loss of appetite, constipation and acid soreness.

(B) local symptoms: sore throat is obvious, especially when swallowing, severe can be radiated to the ear, children often cry because of the inability to swallow, children can block their sleep if they suffer from tonsil hypertrophy, often wake up at night .
