Don’t ignore the symptoms of sensorineural hearing loss!

Sensorineural hearing loss is a common disease in daily life. Its onset is persistent, so it seriously affects people's normal work and study. We should detect and treat sensorineural hearing loss early, otherwise it will seriously affect people's health. Therefore, it is crucial to understand the symptoms of sensorineural hearing loss.

The neurological symptoms of deafness are often manifested as hearing impairment, which is reduced or even disappears. Patients often feel that their ears are ringing or other noises are more obvious in a quiet environment. It may be accompanied by symptoms such as fever, headache, irritability, abdominal distension, back pain and fatigue.

Sensorineural hearing loss refers to a disease in which lesions are located in the hair cells of the auditory nerve or auditory centers at all levels, causing impairment of sound perception and conduction of nerve impulses, resulting in hearing loss or even hearing loss. Hearing loss or complete deafness caused by various factors that damage the auditory nerve is considered sensorineural hearing loss.

There are mainly three types: sensorineural hearing loss, conductive neural hearing loss, and mixed neural hearing loss. The main clinical manifestation of sensorineural hearing loss is a decrease or even disappearance of hearing impairment. Patients often feel that there are cicada sounds or other periodic sounds echoing in their ears. In a quiet environment, the patient feels more intense, and may be accompanied by a variety of systemic symptoms such as fever, headache, irritability, restlessness, abdominal distension, back pain and fatigue.

The symptoms of neurological hearing loss are caused by damage to the organ of Corti in the cochlea, which causes hearing impairment. Acoustic hearing loss can also cause conductive hearing loss. Lesions of the inner ear perilymph and basilar membrane cause sensorineural hearing loss. Lesions of the neural pathways cause neurological hearing loss.

However, it is usually difficult to distinguish the differences between the two clinically, so the two are often combined and referred to as sensorineural hearing loss symptoms. Therefore, clinically, deafness caused by ear complications of various acute and chronic infectious diseases, drug or chemical poisoning, labyrinthitis, hydrops of the membranous labyrinth, temporal bone fracture, acoustic neuroma, craniocerebral trauma, cerebrovascular accident, cerebral vascular sclerosis or spasm, and presbycusis can all be summarized as sensorineural deafness.

1. Tinnitus

Patients with sensorineural hearing loss often experience tinnitus, which often occurs before deafness. Tinnitus is a high-frequency sound, often unilateral, and sometimes bilateral but only noticed on the heavier side. Hearing aids can often reduce or eliminate tinnitus, but hearing aids are ineffective for central tinnitus and objective tinnitus.

2. High-frequency hearing loss

It often occurs in patients with sensorineural hearing loss, who have difficulty hearing high-frequency consonants such as c, s, x, q, j, etc.

3. Dizziness

Hallucinations caused by vestibular lesions in the inner ear. Vertigo, the patient often consciously spins in the surrounding scenery, and there is no feeling of spinning, is it dizziness? Any lesion that can cause unilateral vestibular dysfunction, such as infection or trauma, can cause dizziness. Vertigo is a common symptom of Meniere's disease. Central variables such as acoustic neuroma and multiple sclerosis can also cause dizziness.

4. Revitalization phenomenon

Patients with cochlear neural hearing loss have a re-energization phenomenon. They may be unable to hear moderately loud sounds, but find them unbearable if the sound intensity increases a little. Sensorineural hearing loss caused by damage to the auditory nerve will not experience re-excitation.
