Sudden deafness

Brief introduction to sudden deafness Sudden deafness (hereinafter referred to as abrupt) is a sudden onset of sensory neurological deafness, also known as violent. Its onset is rapid, rapid progress, and the treatment effect is directly related to the time of treatment. It should be regarded as an emergency department for otology. The disease should be differentiated from drug-induced deafness, benign paroxysmal vertigo in children, various chronic otitis media hearing disorders, and congenital middle ear inner ear malformation. Patients with sudden deafness should be at home and rest assured, especially to avoid contact with noise or excessive sound, keep the home environment clean and tidy, and the patient feels comfortable, which is conducive to disease recovery. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: otitis media, tympanic membrane perforation, tympanic membrane trauma, deafness

Sudden deafness

The cause of the sudden death is unknown. There are more than 100 causes of the disease in the literature, many of which are rare. According to Mattox (1977), the cause of the disease is viral infection, vascular disease, endolymphedema, labyrinth. Breakage and the combination of the above factors.

Sudden deafness prevention

1. Patients with sudden deafness should be at home and rest assured. In particular, they should avoid contact with noise or excessive sound, keep the home environment clean and tidy, and the patient's mood is comfortable, which is conducive to disease recovery.

2, to prevent colds, some patients with sudden deafness may have an indirect relationship with the cold, so prevention of a cold can reduce a disease factor.

3, pay attention not to overwork, to do life, sometimes diet, the disease is more common in middle-aged people, so middle-aged people should pay more attention to this.

Sudden deafness complications Complications otitis media tympanic membrane perforation tympanic membrane traumatic deafness

Prolonged periods of time will cause irreversible neuropathological damage that can lead to lifelong deafness.

Sudden deafness symptoms Common symptoms Hearing loss Hearing loss Ear block vertigo Tinnitus Deafness Rehabilitation Cochlear deafness Nausea

(1) Deafness, the disease is fierce, hearing loss can occur in an instant, within hours or days, and there are sudden deafness in the morning, slower deafness can gradually increase, and the progress is stopped after a few days, the degree is mild To the whole sputum, it can be temporary, or permanent, mostly unilateral, occasionally bilateral or simultaneous, may be cochlear sputum, but also for the sinus.

(2) tinnitus, tinnitus occurs before and after deafness, accounting for about 70%, usually appeared several hours before deafness, mostly buzzing, lasting for 1 month or longer, some patients may emphasize tinnitus and ignore hearing loss.

(3) Dizziness, about 2/5 days 1/2 sudden acne with varying degrees of vertigo, about 10% of which are severe deafness, nausea, vomiting, lasting 4 to 7 days, mild halo can exist for more than 6 weeks A small number of patients with dizziness as the main symptom to see a doctor, easily misdiagnosed as Meniere's disease, relieved after a few days, no repeated attacks.

(4) Ear blockage, the ear blockage usually appears before the deafness.

(5) nystagmus, such as vertigo can have spontaneous nystagmus.

Sudden deafness check

(1) Detailed medical history, patients with sudden infection caused by viral infection can clearly provide flu, cold, upper respiratory tract infection, sore throat, paranasal sinusitis, etc., or a history of contact with people infected with the virus, which can occur before hearing loss In a few weeks, vasculopathy-induced sudden death can provide a history of heart disease or hypertension, as well as diabetes, arteriosclerosis, hypercholesterolemia or other systemic diseases affecting the microvascular system. Patients with labyrinth rupture have a clear Forced or experienced a history of changes in air pressure, such as difficult urination, defecation, coughing, sneezing, bending, laughing, etc. or swimming, diving, diving with a snorkel or scuba or unusual flight activities.

(2) Systemic examination, should be directed to the cardiovascular system, coagulation system, metabolism and immune response, neurological examination should exclude the internal auditory canal and cerebellar cerebral horn lesions, vertebral basal and cerebral vascular circulatory disorders, such as the internal auditory canal Slices and cervical vertebrae, CT scan of the head, fundus and cerebral blood flow examination, Wang Shuchun et al. performed cerebral blood flow examination on 104 patients with sudden deafness, and found that the cerebrovascular function of patients with sudden deafness was worse than normal.

(3) Laboratory tests, including blood, erythrocyte sedimentation rate, clotting time, prothrombin time, platelet count, etc. Serological tests for virus and antibody titer measurement, blood sugar, blood lipids, blood nitrogen and serum syphilis test.

(4) Otoscopy, the tympanic membrane is normal, but also reddish.

(5) Hearing examination to understand the nature, extent and dynamics of hearing loss.

(6) vestibular function examination, if necessary, for astigmatism electrogram examination.

Diagnosis of sudden deafness

The disease should be differentiated from drug-induced deafness, benign paroxysmal vertigo in children, various chronic otitis media hearing disorders, and congenital middle ear inner ear malformation.
