orbital cellulitis
Introduction
Introduction to cellulitis Acute suppurative inflammation in the soft tissue or subperiosteal of the iliac crest often has a tendency to spread into the brain, causing permanent vision loss or cavernous sinus thrombosis or purulent meningitis and life-threatening. It can be caused by sinus or tooth infections, or by metastatic spread of infections in other parts or by bacteria brought in by eyelid trauma. Caused by soft tissue infection, often more serious, accompanied by obvious symptoms of systemic poisoning, including fever, sorrow, acute severe disease, increased white blood cells. The eyeball is obviously protruding, the eyelids are red and swollen, the conjunctiva is highly congested and edematous, and even protrudes beyond the cleft palate. Exposure keratitis can be caused by high eyeball protrusion. Eye movements are significantly limited, with side pain when turning. The eyelids are tense and the tenderness is obvious at the time of palpation. If the vision loss and pupil abnormalities are found, it indicates that the lesion involves the tip of the sputum, which is caused by excessive pressure or inflammation and toxin directly invading the optic nerve. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific population Mode of infection: non-infectious Complications: retinopathy, keratopathy
Cause
Causes of cellulitis
Cause
It is caused by the spread of bacterial infection in adjacent tissues. The sinus, nasal cavity and teeth are the most common, followed by facial edema and mumps. It can also occur in periostitis, sputum trauma with foreign body retention, postoperative infection, etc. . Pathogenic bacteria often spread from the venous blood in the adjacent area, and the device develops thrombophlebitis, which in turn is purulent inflammation.
Prevention
cellulitis prevention
Causes of sputum cellulitis is more, in order to prevent the occurrence of this disease, early treatment of various primary suppurative sources, facial and "dangerous triangle" bloated not to squeeze, otherwise it may lead to the occurrence of this disease, once The occurrence of sputum cellulitis should be treated as early as possible in hospital ophthalmology, early diagnosis, early treatment, and good prognosis. In some villages, some patients often use traditional Chinese medicine for external application, delay treatment, make the disease worse, seriously damage vision, and even have serious complications. Should be taken as a warning.
Diet should pay attention to light, mostly with food porridge, noodle soup and other foods that are easy to digest and absorb, avoid fried and spicy food, spicy food such as pepper, onion, raw garlic, pepper and so on.
Complication
Complications of cellulitis Complications retinopathy keratopathy
Delayed treatment may seriously affect vision if not treated in time, and may also lead to severe intracranial complications or sepsis.
Common complications
(1) Incomplete closure of the cleft palate causes exposed keratitis.
(2) intracranial spread of cavernous sinus purulent lesions, causing diffuse meningitis, invading the brain causing brain abscess.
(3) focal pneumonia, lung abscess.
(4) sepsis.
Symptom
cellulitis symptoms common symptoms high fever nausea aversion cold eyeball coma sacral optic atrophy convulsion keratitis meningitis
1, systemic symptoms: can occur aversion to cold, high fever, headache, nausea, vomiting, failure, increased white blood cells, and even paralysis, coma, convulsions and slow pulse.
2, local symptoms: eyelid swelling and heat pain, and a wide range of tenderness, the surface of the dilated venous vascular network, the ball conjunctiva is highly edematous, and even prominent in the cleft palate, the eyeball protrudes straight ahead, the rotation is limited or completely fixed Due to the prominent eyeballs, it can cause exposed keratitis, retinal varices or thrombosis and exudative changes can be seen in the fundus, and can cause optic neuritis and optic atrophy, which can cause serious vision impairment.
In the course of the disease, sometimes the inflammation can resolve on its own, or the pus on the skin surface or the curved conjunctiva at the near gingival margin. After the ulceration, the symptoms can gradually subside, but it can also spread to the skull and cause the sponge. Sinus thrombosis, meningitis or brain abscess is fatal.
Examine
cellulitis inspection
The disease and periostitis have eyeballs, eyelids and conjunctival redness, eye movement restricted, pain and tenderness, but the latter eyeball is often biased to the opposite side of inflammation, and tenderness is more limited.
Diagnosis
Cellulitis diagnosis and identification
Eyelid cellulitis, eyelid abscess and cavernous sinus thrombosis, obvious redness and swelling of the eye, eyeball protrusion and eye movement limitation. Malignant tumors in childhood may have similar clinical manifestations, requiring differential diagnosis, and CT examination may assist diagnosis.
