The basic instruments for surgery generally used in this type of surgery include automatic spring back ear mark forceps, ear guards for oxygen tubing, hartmann ear speculum and so on.


In addition, the current treatment for otosclerosis is mainly surgery, of which stapes resection is the accepted treatment. The instruments commonly used in this type of surgery include extracting forcep, stainless steel autoclave tray, and micro scissors.


Sensorineural hearing loss is arguably the most common hearing loss, and most of the adults with hearing impairment belong to this condition. At present, we cannot repair damaged hair cells through surgery. It is generally recommended to use hearing aids for hearing aid compensation in the world. Before using the hearing aid, it is recommended to go to the pediatrics department of the hospital to let the doctor carefully look at the condition in the ear with aural speculum.

Reasons for Wearing Hearing Aids


The reason for hearing aids is generally to protect residual hearing, improve listening effects, and improve quality of life. Hearing loss should be equipped with hearing aids as soon as possible, because only in time with hearing aids to continuously stimulate the ear nerves, in order to maintain the existing hearing as much as possible.
