Submental space infection

Introduction to the infection of the infraorbital space Infraorbital space infection refers to acute suppurative infection in the infraorbital space. The main clinical manifestations include lymphadenopathy, skin congestion and pain in the infraorbital triangle. basic knowledge The proportion of illness: 0.22% Susceptible people: no specific population Mode of infection: non-infectious Complications: phlebitis

Cause of infection in the infraorbital space

The submental space is located in the upper part of the hyoid bone, which is a single gap in the inferior triangle. There is a small amount of adipose tissue and lymph nodes in the gap. This gap is for the mandibular lingual muscle, and the genioglossus muscle is separated from the sublingual space. The side is connected to the submandibular space, and the infection is easy to spread. The infection of the infraorbital space is mostly caused by inflammation of the lymph nodes. The lower lip, the tip of the tongue, the bottom of the mouth, the sublingual meat, the lymphatic reflux of the mandibular anterior teeth and periodontal tissue can directly flow to the axillary lymph nodes, so the various inflammations in the above areas, Oral mucosal ulcers, stomatitis, etc. can cause axillary lymphadenitis, and then secondary to the subgingival space cellulitis.

Infraorbital space infection prevention

The lower lip, the tip of the tongue, the bottom of the mouth, the sublingual meat, the lymphatic reflux of the mandibular anterior teeth and periodontal tissue can directly flow to the axillary lymph nodes, so it is necessary to actively treat various inflammations in the above areas, oral mucosal ulcers, stomatitis, etc. Avoid causing axillary lymphadenitis, and then secondary to the underarm space cellulitis.

Subgingival space infection complications Complications phlebitis

Caused by multiple fascial space infections, and infections to the intracranial, mediastinal barrier spread, leading to cavernous sinus thrombophlebitis, brain abscess, mediastinal abscess and sepsis and other serious complications.

Symptoms of subgingival infections Common symptoms Congestive edema abscess

Because the infection of the infraorbital space is mostly caused by the spread of lymph nodes, the general progress of the disease is slow. The early stage is limited to the swelling of the lymph nodes, and the clinical symptoms are not obvious. When the inflammation of the lymph nodes spreads to the outside of the node, it will cause the interstitial fossa tissue inflammation. The swelling range is extended to the entire underarm triangle area, the skin is congested, pain, and the local skin is purple after the abscess is formed. The depression has edema and undulation, and the infection may show signs corresponding to the posterior submandibular space.

Examination of the infection of the infraorbital space

Oral examination.

The deep abscess is not obvious, and sometimes it needs to be diagnosed by puncture.

Diagnostic diagnosis of infraorbital space infection

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