Stapedectomy surgery is a procedure done on a person’s middle ear for curing otosclerosis to improve his/her hearing capabilities. Generally as a result of the inner ear damage, abnormal bone growth, ear infections etc., a person might have a reduced sensitivity to the sounds that can be heard normally, this necessitates a stapedectomy surgery for making the person get back his sensitivity to sound. This procedure enables the transmission of the sound vibrations to the inner fluids of the ear. In this surgery, the middle ear innermost bone is replaced by a small plastic tube that surrounds a short length of wire which is made of stainless steel.
Symptoms of otosclerosis
- The patient will start hearing whispers or low pitched sounds
- Hissing in the head or ears
- Balance problems
- Gradual hearing loss
What is Hearing Loss ?
A reduced sensitivity to the sounds that can be heard normally. The problem of hearing impairment / hearing loss is due to the problem in either one or more parts of the ear.
Causes of Deafness
Gradual Increase of Earwax : The development of ear wax can obstruct the ear canal and also preventing the transmission of sound waves. The blockage of the ear wax can cause conductive hearing loss that can be corrected by removing the earwax.
Bursting of the Eardrum (tympanic membrane perforation) : the bursting of the ear drum can caused by many factors such as regular poking the eardrums that can result in infections, loud noises and unexpected changes in the pressure. All these can rupture the eardrum.
Inner Ear Damage : Over exposure to the loud sounds can cause damage to the nerve cells or hair in the cochlea which transmits the sound signals to brain. As the nerve cell gets damaged, the electric signals cannot be transmitted properly that ultimately leads to hearing loss. The person can experience difficulty in picking out the words against background noises.
Abnormal Bone Growths, Tumors or Ear Infections : Either in the outer region of the ear or in the middle of the ear, all these problems can lead to hearing loss.
The types of hearing loss/hearing impairment can be classified by knowing which part of the auditory system has been damaged. Sensorineural hearing loss, mixed hearing loss and conductive hearing loss are the three types.
What is Stapedectomy?
The procedure by which the fixed stapes are removed and is then replaced with a prosthesis. This procedure enables the transmission of the sound vibrations to the inner fluids of the ear for the purpose of hearing. The condition that causes the problem of stapedectomy is Otosclerosis. Otosclerosis can be hereditary or can also affect without any prior family history. It generally involves about 2 % of the population. The problem of hearing is first noticed at the age of twenties and can lead to hearing loss in the later stages of the life.
Procedure of Stapedectomy
The surgical procedure is performed in which the middle ear innermost bone of the 3 bones ( Malleus, stapes and the incus) is removed. It is then replaced by a small plastic tube that surrounds a short length of wire made up of stainless steel.
Causes of Stapedectomy
The stapes fixation results in two chief causes. First is the abnormal mineralization of the otosclerosis (temporal bone) which is regarded as a disease process. The other cause is the stapes congenital malformation.
