Buccal space infection

Introduction to buccal infection Buccal space infection refers to acute suppurative infection in the buccal space, mainly characterized by redness and swelling of the vestibular sulcus in the mandibular or maxillary molar region. The vestibular groove becomes shallow and undulating, with severe pain, a sense of undulation, easy puncture of pus, and redness of cheek skin. Relatively light. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: swelling

Buccal space infection etiology

The buccal space has a generalized narrow sense. The generalized buccal space refers to the gap between the buccal skin and the buccal mucosa. The upper boundary is the lower edge of the humerus; the lower boundary is the lower edge of the mandible; the front boundary is from the lower boundary. The lower edge of the bone, the line connecting the mouth to the lower edge of the mandible; the posterior boundary is equivalent to the front of the masseter muscle; the deep surface is the structure of the diaphragm and the pterygopalatine ligament, and the abdomen contains the cellulite, adipose tissue (buccal fat) Outside the pad, there are facial nerves, buccal nerves, external maxillary artery, veins in front of the veins, as well as buccal lymph nodes and maxillary lymph nodes. The narrow cheek space refers to a small gap between the masseter muscle and the buccal muscle. The fascial space, in which the buccal fat pad is located, is also referred to as the masstric-brccal space.

Buccal space by the blood vessels, fat connective tissue and the infraorbital space, sacral space, masseter muscle gap, wing jaw gap, underarm space.

Buccal infection can be caused by apical infection of the upper and lower mandibular posterior teeth or alveolar abscess, as well as buccal skin damage, buccal mucosal ulcers, inflammation of the buccal or maxillary lymph nodes.

Buccal infection prevention

Active treatment of apical infections or alveolar abscesses from the upper and lower mandibular posterior teeth, as well as buccal skin lesions, buccal mucosal ulcers, inflammation of the buccal or maxillary lymph nodes.

Buccal infection complications Complications swelling

The site of abscess formation determines the severity of infection in the buccal space. Abscess in the subcutaneous or submucosal buccal, the progress of the disease is slow, and the swelling range is limited. When the infection affects the buccal fat pad, the inflammation develops rapidly, and the swelling range affects the entire cheek. It can diffuse into the gap and form a multi-gap infection.

Buccal space infection symptoms common symptoms severe pain molar abscess fever

History

There is acute suppurative wisdom tooth pericoronitis, or acute apical periodontitis of upper and lower jaw molars.

2. Clinical manifestations

When the abscess occurs between the buccal mucosa and the buccal muscle, the vestibular groove of the mandibular or maxillary molar area is red and swollen, and the vestibular groove becomes shallow and undulating, with severe pain, a sense of fluctuating, easy puncture of pus, and redness and swelling of the cheek skin. Light, abscess occurs between the skin and the buccal muscles, especially when the buccal pad is fully affected by inflammation, the cheek skin is red and swollen, the skin is swollen and shiny, and the inflammatory edema spreads beyond the anatomical perimeter of the buccal space, but the redness and tenderness center remains. The position of the buccal muscles, local puncture can extract pus, patients with fever and increased white blood cells.

The clinical features of the buccal space depend on the location of the abscess, the abscess under the subcutaneous or submucosal buccal, the progression of the disease is slow, and the extent of swelling is limited. When the infection affects the buccal fat pad, the inflammation develops rapidly, and the swelling range affects the entire cheek. And can diffuse into the gap, forming a multi-gap infection.

Examination of buccal infection

Blood routine examination, white blood cells rise.

Local puncture can extract pus.

Diagnosis of buccal infection

diagnosis

Detailed medical history, combined with clinical manifestations and anatomical features to analyze the source of infection, coupled with laboratory tests, puncture examinations, etc., is not difficult to make a correct diagnosis.

Differential diagnosis

To be differentiated from mumps and tonsillitis.
