Deafness is usually not a precursor of disease but a symptom of disease. Cerumen embolism, otitis media, sudden deafness, and acoustic neuroma all have symptoms of deafness.
1. Cerumen impaction: When cerumen secretion from the external auditory canal is excessive or its expulsion is obstructed, it gradually forms a mass and blocks the external auditory canal, forming a cerumen impaction. There will be conductive deafness and a feeling of ear blockage and stuffiness.
2. Otitis media: common inflammation of the middle ear mucosa, usually accompanied by obvious pain, accompanied by pus in the ear canal, hearing loss.
3. Sudden deafness: Sudden, unexplained sensorineural hearing loss. Hearing loss of ≥20 dBHL in at least two adjacent frequencies may be accompanied by simultaneous or sequential tinnitus or vertigo.
4. Auditory neuroma: It is a benign tumor originating from the Ⅷth pair of cerebral nerves, and is also known as vestibular nerve sheath tumor because most of the tumor comes from the Schwann cells of the vestibular nerve. When the tumor is located in the internal auditory canal, it mainly manifests as hearing loss, tinnitus and vestibular nerve dysfunction.
There are many other diseases that cause deafness, such as Meniere’s disease, otosclerosis, senile deafness, congenital deafness, etc. It is recommended that deafness should be examined in a timely manner in the hospital, and the diagnosis is clear and targeted treatment.
