A stapedectomy surgery involves the removal of complete or part of the original stapes bone and replacing it with an artificial device. This procedure restores the transmission of sound waves to the inner ear for hearing. Read more: What Is Stapedectomy Surgery? Article

Related Disease Conditions
Hearing loss (deafness) may be present at birth or it may manifest later in life. Deafness may be genetic or due to damage from noise. Treatment of deafness depends upon its cause. Sensorineural hearing loss can be caused by conditions affecting the cochlea, eighth cranial nerve, spinal cord, or brain. Examples of conditions that can lead to sensorineural hearing loss include Meniere's disease, noise-induced hearing loss, hearing loss of aging (presbycusis), nerve injury from syphilis, hearing loss of unknown cause (idiopathic hearing loss), nerve tumors, and drug toxicity (such as aspirin and aminoglycosides).
Noise-Induced Hearing Loss and Its Prevention
Noise-induced hearing loss may be an acoustic trauma, which causes temporary hearing loss, or it may be permanent due to an acute acoustic trauma. Experts agree that continual exposure to more than 85 dBs (decibels) is dangerous to the ears. Ear plugs and ear muffs can help prevent noise-induced hearing loss as well as decreasing exposure to loud noises.
What is the purpose of impedance audiometry?
The main purpose of impedance audiometry is to check the status of the tympanic membrane and middle ear. It checks how well the vibrations get transmitted from the tympanic membrane (eardrum) further into the ear.
How Is a Pure Tone Audiometry Test Done?
An audiometry test is done to evaluate your hearing capacity. It may be done in patients with deafness to determine the cause and degree of hearing loss. The test is generally advised by an ear, nose, and throat (ENT) surgeon and performed by an audiologist. The test uses different pitches of sound to measure how sensitive your sense of hearing is.
Why Is Speech Audiometry Performed?
Speech audiometry is an essential tool to assess hearing loss. It is usually performed for the assessment/examination of intensity and type of hearing loss, Word recognition abilities, and Discomfort or tolerance to any speech stimuli.
