Infratemporal space infection

Introduction to the infection of the infraorbital space Infraorbital space infection refers to acute suppurative infection of the infraorbital space. The main clinical manifestations are swelling of the upper and lower iliac arch and posterior mandibular branch. There is deep tenderness accompanied by varying degrees of mouth opening. basic knowledge The proportion of illness: 0.87% Susceptible people: no specific population Mode of infection: non-infectious Complications: headache

Cause of infection in the infraorbital space

The infratemporal space is located below the humerus, the anterior boundary is the maxillary nodules and the posterior maxillary condyle; the posterior border is the styloid process and the styloid process muscles; the inner boundary is the outer side of the sphenoid pterygoid outer plate; the outside is the lower jaw The upper part is the upper part and the zygomatic arch; the upper boundary is the lower part of the pterygoid and the lower part of the sacral sac; the lower boundary is the plane of the lower edge of the pterygoid muscle, and is demarcated from the space of the lower wing stool. The fat tissue in the gap, the arteriovenous artery in the jaw, The branches of the venous venous plexus, the trigeminal nerve, and the branches of the mandibular branch are respectively connected with the sacral, pterygoid, parapharyngeal, buccal, and pterygium; and the sacral sulcus, the foramen ovale and the sinus hole are respectively associated with the iliac crest and the intracranial Tonga.

It can be spread from adjacent gaps, such as the space under the wing stool; it can also be infected by maxillary nodules, foramen ovale, round hole block anesthesia; or infection by root canal infection or extraction after maxillary molars .

The position of the inferior temporal space is deep, concealed, and the appearance of the infection is often obvious. The examination can be found that the upper and lower jaws of the zygomatic arch are slightly swollen, with deep tenderness, with varying degrees of mouth opening, but underarm Interstitial infections often occur in interstitial spaces, and may be associated with swelling of the ankle, parotid masseter, buccal and intraoral maxillary nodules, and the corresponding symptoms of the combined interstitial infection.

Infraorbital space infection prevention

Active treatment of maxillary third molar pericoronitis, periapical periodontitis, nerve block anesthesia after upper alveolar, oval anesthesia, underarm-trigeminal-sympathetic nerve closure, to prevent infection.

Subgingival space infection complications Complications

The abscess has a wide range and can affect the ankle, parotid gland and cheek at the same time, and induce infections everywhere.

Symptoms of infection under the armpits Common symptoms Appetite loss systemic infection symptoms

1. History of the inferior temporal space infection may have maxillary third molar pericoronitis, history of periapical periodontitis, upper alveolar nerve block anesthesia, foramen ovale anesthesia, underarm-trigeminal-sympathetic nerve closure history can not be ignored .

2. Clinical manifestations Because the anatomy of the abscess is deep and concealed, although the patient has high fever, headache, loss of appetite, increased white blood cells and other symptoms of systemic infection, the maxillofacial redness is not obvious, but the indirect manifestation is the affected side. The edema of the maxillary nodules is very obvious. The vestibular sulcus is swollen and shallow or bulging. The tenderness is obvious and there is a sense of fluctuation. Puncture is easy to poke at this place. The upper and lower jaws have swelling and tenderness.

Examination of the infection of the infraorbital space

Laboratory examination, puncture and X-ray examination.

Diagnostic diagnosis of infraorbital space infection

Chronic inflammation of the infraorbital space must be differentiated from the tumor of the infratemporal fossa. CT and MRI are good identification methods.
