Orbital periostitis
Introduction
Introduction to orbital periostitis Periostitis of the tibia refers to an inflammatory lesion of a fibrous connective tissue membrane covering the surface of the tibia. According to the different sites of the disease, orbital periostitis can be divided into two types. The anterior periostitis is more common, and the affected side is skin. Red and swollen, can touch the thick bone edge and tenderness, while the eyeball shifts to the opposite direction of the lesion, the diagnosis is easier. In the posterior part of the periostitis, the lesions are deep, although there are symptoms such as ocular protrusion and tenderness, but the diagnosis is difficult. The above two types of periostitis may sometimes affect each other. The treatment of this disease is mainly for the treatment of the cause, systemic administration of quantitative broad-spectrum antibiotics, corticosteroids if necessary. Local with reasonable treatment or hot compress, purulent can be used to open the drainage, deep drainage should be placed in the drainage strip, if the fistula has been formed and prolonged unhealed, there may be residual bone residual, should be surgically removed after acute inflammation control. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: valgus valgus meningitis brain edema
Cause
Causes of orbital periostitis
1. Caused by a systemic infectious disease.
2, paranasal sinus infection: such as frontal sinusitis or anterior ethmoid sinusitis can cause anterior periostitis; posterior sinusitis or sphenoid sinusitis can cause posterior periostitis.
3. Spread of eyelids and lacrimal sac lesions (tuberculosis, syphilis or fungal infections).
4. Traumatic infections.
Prevention
Orbital periostitis prevention
1. Pay attention to facial hygiene, correct bad habits such as picking nose and pulling nose.
2. When the nose, lips, and cheeks are swollen, they should be treated promptly, and should not be squeezed or abused.
Complication
Orbital periostitis complications Complications, valgus meningitis, cerebral edema
Severe cases can be combined to form scar valgus valgus, such as backward spread to the brain can be complicated by meningitis or cerebral edema.
Symptom
Orbital periosteal inflammation Symptoms Common symptoms Inflammatory visual impairment Eyeball protrusion Cellulitis Circumflex conjunctival hyperemia
Consciously there are localized pains, especially in the evening, the pain is increased, and the whole body is accompanied by headaches and increased body temperature.
Signs: Divided by the edge or deep position of the eyelid.
Anterior periostitis: blepharospasm and bulbar conjunctival hyperemia, edema, eyeball biased to the contralateral side, limited movement, obvious tenderness at the eyelid margin, in the late stage of inflammation can be self-destructive, pus out and self-healing, or recurrent episodes of fistula, serious Can be combined to form scarring eversion.
Posterior periostitis: the eyeball protrudes forward. If the lesion is at the tip of the eyelid, it presents with supracondylar or apical syndrome. The ptosis of the upper eyelid, the fixation of the eyeball cannot move, the pupil is dilated, the response to light disappears, and even visual impairment. If it spreads backward into the skull, it can be complicated by meningitis or brain edema.
Examine
Examination of orbital periostitis
The skin of the anterior tibio-periostitis is red and swollen, can touch the thick bone edge and have tenderness. At the same time, the eyeball shifts to the opposite direction of the lesion. The diagnosis is easy. The posterior periostitis is deep because of the lesion. Prominent and tender symptoms, but the diagnosis is more difficult.
Diagnosis
Diagnosis and differentiation of orbital periostitis
1. Cellulitis of the cellulitis: often unilateral onset, eyeball fixation is incomplete, the pupil indirect reduction of light response is rare, and systemic symptoms are also mild.
2. Intraorbital tumors: When the tumor is secondary to infection, it is similar to the cavernous sinus thrombosis, but the symptoms of this infection often occur after the eyeball is prominent, and can be identified according to the medical history.
