Redness of the tympanic membrane and redness behind the ear are most often seen in patients with intracranial venous sinus occlusive cranial hypertension, most patients have perforated tympanic membrane with pus, and some patients have redness of the tympanic membrane and redness behind the ear. Intracranial venous sinus and venous thrombosis is the main cause of cerebral venous reflux and impaired cerebrospinal fluid absorption, which results in cranial hypertension, and this particular type of cranial hypertension is called venous sinus occlusive cranial hypertension. Transverse sinus thrombosis is mostly due to otitis media or mastoiditis lasting several weeks, the patient has headache, which is aggravated by head rotation, vomiting, skin vein congestion behind the ear, and if phlebitis has extended to the internal jugular vein, there is tenderness in the neck, optic disc edema, which is mostly confined to the diseased side and is not severe, and focal encephalitis symptoms are convulsions and light hemiparesis on the opposite side. When the left transverse sinus thrombosis can manifest aphasia, most patients have tympanic membrane perforation and pus flow, and some patients have red tympanic membrane and postauricular redness and swelling. The diagnosis of intracranial venous sinus occlusion mostly depends on clinical manifestations, such as headache, nausea, vomiting and optic disc edema of cranial hypertension symptoms, as well as local neurological localization signs and local infection lesions related to venous sinus thrombosis and related systemic factors. The diagnosis can be made when the venous sinus occlusion is seen in the stage of CT scan. In recent years, due to the large number and wide application of antibiotics, venous sinus thrombosis caused by local infection tends to be subacute and chronic in origin, and some patients only have chronic cranial hypertension and lack other typical manifestations of venous sinus thrombosis, and only show symptoms of high cranial pressure. 2.Electroencephalogram (EEG) is a graph obtained by amplifying and recording the spontaneous biopotentials of the brain from the scalp through an instrument. 3.Endoscopy Endoscopy is an optical instrument, which is sent into the body from outside the body through the natural cavity of the human body to examine the disease in the body. It can directly observe the lesion in the internal cavity of the organs, determine its location and scope, and can take photos, biopsy or brush the film, which greatly improves the accuracy of cancer diagnosis and can carry out certain treatments. It is suitable for the diagnosis of bronchial lesions, upper gastrointestinal lesions, lower gastrointestinal lesions and ear, nose and throat lesions, etc.
