Redness of the tympanic membrane, redness and swelling behind the ear are mostly seen in patients with intracranial venous sinus occlusive cranial hypertension, most of the patients have tympanic membrane perforation and pus, and a part of the patients have redness of the tympanic membrane and redness and swelling behind the ear. Intracranial venous sinus and venous thrombosis is the main cause of cerebral venous return and cerebrospinal fluid absorption disorders, the result is the production of cranial hypertension, this particular type of cranial hypertension is called venous sinus occlusive cranial hypertension. Occlusive cranial hypertension of the venous sinuses is caused by a variety of reasons, chronic otitis media secondary to venous sinus thrombosis is the most common cause. It can also be caused by some systemic diseases, such as extracranial tumors, blood disorders, metabolic disorders and taking certain drugs. Currently, it is thought that the disease is also associated with menstrual disorders, pregnancy, oral contraceptives, vitamin A hypervitaminosis, and the use of drugs such as tetracyclines, furans, nalidixic acid, and corticosteroids. Epidemiologic surveys have reported a higher prevalence of overweight and obese people than normal weight people. In recent years, with the wide application of neuroimaging techniques, such as CT, MRI and digital subtraction cerebral angiography, and the accuracy and increase of laboratory tests, patients with idiopathic cranial hypertension should undergo targeted imaging and laboratory tests in addition to careful questioning of the patient and physical examination in order to find out the relevant etiology. Venous sinus occlusive cranial hypertension most often occurs after thrombosis of the superior sagittal sinus, straight sinus, transverse sinus, and cavernous sinus. Symptoms of thrombosis vary according to the site. Clinically, they can be divided into two categories: infectious and non-infectious, the latter mostly caused by craniocerebral trauma, wasting disease (such as advanced cancer, cachexia), certain blood diseases (leukemia, erythrocytosis, severe anemia) and severe dehydration. The former are mostly secondary to infections of the head and face, as well as purulent meningitis, brain abscesses, sepsis, etc.
