Single sided deafness refers to the loss of hearing in one ear. This is a common problem, often caused by viral infection, Meniere's disease or head and ear injuries. 



The Cause of Single Sided Deafness

The cause of single sided deafness is complex, which has congenital and acquired factors, among which suppurative otitis media is the most important deafness disease in conductive deafness. In recent years, secretory otitis media has become the main cause of hearing loss in children. If there are symptoms of deafness, it is recommended to go to the hospital immediately for examination. Doctors use ear speculum, ent micro ear forceps, leatherman emt scissors and other tools to examine the patient's ears.


The causes of conductive deafness include congenital and acquired causes. Congenital causes include malformations of the external ear and middle ear, such as congenital atresia of the external auditory canal or hypoplasia of the tympanic membrane, ossicular, cochlear window and vestibular window. Acquired causes include obstruction of external auditory canal, such as cerumen embolism, bone wart, foreign body, tumor and inflammation. 


Presbycusis is often caused by arteriosclerosis, hyperostosis of bone and insufficient blood supply. Both craniocerebral trauma and temporal bone fracture can damage the inner ear structure, cause internal ear hemorrhage, or cause internal ear injury due to strong vibration, which can lead to sensorineural deafness. In addition, the injury of the internal ear structure by operation can also lead to deafness. Therefore, it is necessary to use qualified and high quality medical tools such as surgical speculum, crocodile ear forceps and micro needle holder. Sudden deafness is a sudden sensorineural deafness of unknown cause. At present, it is considered that acute microcirculation disturbance and virus infection are the common causes of this disease.

In addition to the above reasons, prolonged exposure to noise can also lead to deafness. Noise induced deafness is a kind of slowly progressive sensorineural deafness caused by long-term exposure to more than 85dB noise. The main manifestations were tinnitus and deafness. Blast deafness is an acute deafness caused by sudden strong pressure wave and strong pulse noise. Tympanic membrane and cochlea are the most vulnerable parts of auditory organ. When exposed to noise above 90dB, cochlear damage can occur. If the intensity exceeds 120dB, permanent deafness can be caused.


Meniere disease is an internal ear disease with unknown causes, and the main symptoms are paroxysmal vertigo, fluctuating deafness and tinnitus. The cause of Meniere disease is unknown, which may be related to congenital inner ear abnormality, plant nervous dysfunction, virus infection, allergic, endocrine disorder, salt and water metabolism disorder. At present, it is generally believed that the main cause of the disease is the obstruction of internal lymph flow or absorption disorder. 


For deaf patients, timely treatment is the best choice. Doctors will decide the treatment plan according to the severity of deafness, and sometimes they will operate on the patients. If surgery is needed, high quality medical tools such as castro needle holder, nose speculum, ophthalmic cannulas and hartmann ear forceps are important items to ensure the smooth operation.
