Superior orbital fissure syndrome

Introduction The supracondylar fissure is located on the outer side of the optic nerve of the eye, and is composed of a sphenoidal wing at the junction of the superior wall of the ankle and the outer wall of the ankle. Thereby the middle cranial fossa communicates with the eyelids. The posterior cleft palate meets the infraorbital fissure. The III, IV, VI cranial nerves and the ocular branches of the V-brain nerve, the superior ocular vein, the sacral branch of the middle meningeal artery, and the sympathetic nerves pass through the split. The supracondylar fissure syndrome can occur in the presence or absence of lesions in the iliac crest or in the iliac crest. Symptoms of ipsilateral oculomotor, trochlear and abductor nerve paralysis appear in the whole eye muscle paralysis, which is characterized by ptosis of the upper eyelid, fixation of the eyeball, various movement disorders, dilated pupils, and disappearance of light and regulation.

Cause

The cause is not fully understood. But there are various reasons as follows.

(1) Non-specific inflammation in the sputum affects the supracondylar fissure or inflammatory granuloma tissue. Orbital soft tissue inflammation secondary to extraocular muscle surgery or paranasal sinus inflammation spreads to the supracondylar meninges and cavernous sinus, and the infection of the central nervous system affects the supracondylar stenosis.

(2) Intraocular or intracranial tumors affect the supracondylar fissure, such as the wrong hook tumor.

(3) Traumatic tibiofibular fractures, edema, and blood pressure.

Eye and sacral area CT examination of eyelid examination

Diagnose based on:

1 eyelid X-ray film pay attention to whether the sacral fissure is narrowed or hardened or destroyed.

2B ultra-examination, if necessary, except for CT examination, there is an internal space-occupying lesion in the upper sac.

3 Please consult the otolaryngology doctor for sinusitis.

4 based on clinical manifestations and medical history.

Differential diagnosis

Other painful ophthalmoplegia and similar symptoms of supracondylar syndrome, such as metastatic intraorbital tumor, extensive nasal mass, systemic vasculitis must be excluded, according to X-ray film and blood test can be identified diagnosis.
