Brain herniation in the ear meninges
Introduction
Introduction of meningeal cerebral palsy in the ear Intrathecal meningeal cerebral palsy refers to bone defects in the tympanic mastoids caused by various reasons, causing the meninges of the brain to penetrate into the tympanic cavity or the mastoid cavity. More common in otogenic intracranial complications of cholesteatoma extensive bone destruction and severe intracranial infections, such as meningitis, brain abscess and lateral sinus thrombophlebitis, so that intracranial pressure continues to increase, cerebral temporal lobe or cerebellum The lateral side is inserted into the tympanic cavity or the mastoid cavity through the bone defect, and the infarction and necrosis of the brain tissue promotes intracranial infection and high intracranial pressure, forming a vicious circle. basic knowledge The proportion of sickness: 0.01% Susceptible people: no special people Mode of infection: non-infectious Complications: cerebrospinal fluid leakage
Cause
Intracranial meningeal cerebral palsy
Cause:
More common in otogenic intracranial complications of cholesteatoma extensive bone destruction and severe intracranial infections, such as meningitis, brain abscess and lateral sinus thrombophlebitis, so that intracranial pressure continues to increase, cerebral temporal lobe or cerebellum Lateral bone defect into the tympanic cavity or mastoid cavity, infarction and necrosis of brain tissue, and promote intracranial infection and high intracranial pressure, forming a vicious circle, improper surgical treatment such as removal of mastoid meningeal plate and sigmoid sinus bone Too many plates, excessive meninges when the brain abscess, or long-term drainage of abscess can be induced.
Prevention
Intracranial meningeal cerebral palsy prevention
1. There is no effective preventive measure for this disease. Early diagnosis and early treatment of the primary disease is the key to the prevention and treatment of this disease.
2. This disease is relatively rare. Domestic Cheng Shaoguang and Shi Chunhua have reported less than 10 cases.
Complication
Intracranial meningeal cerebral palsy complications Complications cerebrospinal fluid leakage
There are meningeal brain tissue in the ear to fill the tympanic cavity and mastoid cavity and necrosis, and even cerebrospinal fluid leakage can form, and soon the intracranial complex infection can occur and die.
Symptom
Cerebral cerebral palsy symptoms in the ear Common symptoms Low fever brain abscess Meningitis Cerebral palsy
Brain abscess or meningitis is not cured soon, there is low fever, headache, brain tissue in the ear is filled with tympanic cavity and mastoid cavity and necrosis, and even cerebrospinal fluid leakage can form, and soon the intracranial complex infection can occur and die.
Examine
Examination of meningeal cerebral palsy in the ear
Urgent CT examination.
Diagnosis
Diagnosis and identification of meningeal cerebral palsy in the ear
The disease is mainly differentiated from cerebral palsy caused by other causes. This disease has a history of extensive bone destruction and severe intracranial infection of otogenic intracranial complications of cholesteatoma.
