Traumatic deafness

Introduction to traumatic deafness Traumatic deafness refers to bilateral severe high frequency neurological spasm or mixed hemorrhoids caused by closed trauma of the skull. It is mostly caused by divers, blasters, soldiers, airport workers and physical researchers. The diver is decompressed too quickly when the water rises. The gas originally dissolved in the tissue or body fluid does not diffuse to form tiny bubbles. In addition, the blood is highly coagulated and is prone to micro-thrombosis during deep dive. One of them appears in the inner ear, which can affect the auditory nerve and the vestibular sensory epithelium, leading to latent convulsions. The powerful air shock wave and the sound pressure wave energy of the impulse noise during the explosion cause damage to various structures of the middle ear and inner ear, causing dizziness, tinnitus and deafness (knocking sputum), the latter often being sensory or mixed. Can be partially restored. Long-term exposure to a continuous noise environment can cause noise. In addition, physical factors such as infrasound, radiation, and microwave radiation, often mixed with audible sounds, can also cause damage to the middle ear and/or inner ear, causing sensorineural or mixed convulsions. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: dizziness

Causes of traumatic deafness

In the case of closed cranial trauma, if the head is fixed, the pressure wave is transmitted to the base of the skull. The relative mobility of the tibial plate is too large due to the inertia of the hearing bone, resulting in labyrinth, inner ear hemorrhage, sensory cells and ganglion cells.

Traumatic deafness prevention

1. Extensive publicity to prevent close relatives from getting married, actively prevent and cure diseases during pregnancy, and reduce birth injuries. Early detection of deafness in infants and young children, early treatment or early hearing and speech training.

2. Improve living standards, prevent and treat infectious diseases, exercise the body, ensure physical and mental health, and slow down the aging process.

Traumatic deafness complications Complications

Deafness is a disease caused by a variety of causes. If you do not actively treat it, it will eventually lead to loss of language ability.

Traumatic deafness symptoms Common symptoms Dizziness, deafness, tinnitus, neurological deafness

Most of the clinical manifestations were bilateral recurrent neurological spasm or mixed hemorrhoids, accompanied by high-pitched tinnitus and dizziness, and balance disorders. Symptoms can be relieved after a few months, but it is difficult to fully recover. When the humerus is transversely fractured, the fracture line perpendicular to the axis of the rock often crosses the bone labyrinth or the inner ear canal to damage the structures contained therein, and severe sensorineural hearing loss, as well as dizziness, nystagmus, facial paralysis and cerebrospinal fluid otorrhea. The diver's decompression is too fast due to rising water, and the gas originally dissolved in the tissue or body fluid does not diffuse to form tiny bubbles; in addition, the blood is highly coagulated during deep dive and is prone to micro-thrombus; One of them appears in the inner ear, which will block the microcirculation of the cochlea, cause blood supply reduction, metabolic disorders, and then involve the auditory and vestibular sensory epithelium, leading to potential convulsions. The powerful air shock wave and the sound pressure wave energy of the impulse noise during the explosion cause damage to various structures of the middle ear and inner ear, causing dizziness, tinnitus and deafness (knocking sputum), the latter often being sensory or mixed. Can be partially restored. Long-term exposure to continuous noise can cause noise. In addition, physical factors such as infrasound, radiation and microwave radiation, which are often mixed with audible sounds, can also cause damage to the middle ear and/or inner ear, causing sensorineural or mixed convulsions.

Traumatic deafness examination

Hearing test, vestibular function test, Eustachian tube test.

Diagnosis and diagnosis of traumatic deafness

Comprehensive and systematic collection of medical history, detailed ear and nose examinations, strict auditory function, vestibular function and eustachian tube function testing, necessary imaging and whole body examination are the basis for diagnosis and differential diagnosis. An objective comprehensive analysis is the premise.
