Temporal space infection
Introduction
Introduction to sputum infection Interstitial infection refers to an acute suppurative infection in the intercondylar space. The main clinical manifestations are: swelling limited to the ankle, or extensive swelling of the parotid muscle area, cheeks, ankles, and ankles. The diaphragm is thick, the tendon fascia is dense, and the deep abscess is difficult to wear on its own. The pus accumulates on the surface of the tibia for a long time, which can cause osteomyelitis. The bone wall of the skeletal scale is thin, and there are few barriers between the internal and external bone plates. The infection can be directly from the bone. Sew or through the blood vessels that enter the meninges, catheter meningitis, brain abscess and other complications. basic knowledge The proportion of illness: 0.02% - 0.04% Susceptible people: no specific population Mode of infection: non-infectious Complications: osteomyelitis meningitis brain abscess
Cause
Cause of interstitial infection
Primary infection (55%):
Interstitial infections often spread from the masseter muscle space, the pterygopalatine space, the infraorbital space, and the buccal space infection. The diaphragm is thick, the fascia is dense, and the deep abscess is difficult to wear on its own. The pus accumulates on the surface of the tibia for a long time, which can cause osteomyelitis.
Secondary infection (45%):
Otogenic infections (suppurative otitis media, sputum mastoiditis), secondary infections of the ankle and ankle injury can first affect the intercondylar space. The clinical manifestations of the intercondylar space depend on a simple intercondylar space infection or with adjacent multiple gap infections.
Prevention
Interstitial 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.
Complication
Interstitial infection complications Complications osteomyelitis meningitis brain abscess
Deep abscess compression of the tibia is prone to osteomyelitis, and because the bone wall of the sacral scale is very thin, meningitis and brain abscess can also be complicated.
Symptom
Symptoms of interstitial infection, common symptoms, systemic infection, poisoning symptoms, loss of appetite, molars
1. History: There may be periorbital inflammation of the maxillary third molar before the infection of the infraorbital space, history of periapical periodontitis, anesthesia of the superior alveolar nerve block, anesthesia of the foramen ovale, and the history of the infraorbital-trigeminal-sympathetic nerve is not acceptable. Neglect.
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 symptoms of maxillofacial redness and swelling are not obvious, but indirect manifestation is The edema of the lateral 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. The pus is easy to puncture at this place. The upper and lower jaws have swelling and tenderness. .
The clinical manifestations of the intercondylar space depend on simple intercondylar space infection or adjacent multiple interstitial infections. Therefore, the swelling range can be limited to only the ankle or the parotid masseter muscle area, and the cheeks, ankles, ankles and other areas are extensively swollen. The area showed depression edema, tenderness, chewing pain and varying degrees of mouth opening. The shallow interstitial abscess can feel the sense of fluctuation, and the deep interstitial space can be clear by puncture and pus extraction.
The diaphragm is thick, the tendon fascia is dense, and the deep abscess is difficult to wear on its own. The pus accumulates on the surface of the tibia for a long time, which can cause osteomyelitis. The bone wall of the skeletal scale is thin, and there are few barriers between the internal and external bone plates. The infection can be directly from the bone. Sew or through the blood vessels that enter the meninges, catheter meningitis, brain abscess and other complications.
Examine
Examination of interstitial infection
Laboratory examination: B-mode ultrasound imaging can determine whether an abscess is formed. CT examination can not only understand the existence of abscess, the tissue anatomy level of the ankle, but also the presence or absence of bone destruction of the humerus and the presence or absence of infection in the skull. A thick needle puncture, from the center of the ankle abscess to the bone surface, and then withdraw and slowly withdraw the needle to extract the pus.
Diagnosis
Diagnostic diagnosis of sputum gap infection
The disease should be differentiated from the huge rickets of the ankle. The latter can be used to determine whether the abscess is formed. CT examination can not only understand the existence of abscess, the tissue anatomy level of the ankle, but also the presence or absence of bone destruction of the humerus and the presence or absence of infection in the skull. A thick needle puncture, from the center of the ankle abscess to the bone surface, and then withdraw and slowly withdraw the needle to extract the pus.
