This first and most visible component, the Outer Ear, is comprised of the external fleshy part of the ear and the ear canal; they can be thought of as a radar station, collecting sounds and channeling them to the next component.
Changes here, such as heavy accumulations of wax or infections, can result in significant losses of conductive hearing. Some birth defects restrict the development of the ear canal and result in maximal loss of hearing from birth on. The ear drum can be perforated by an accidental injury and bring on infection or other injuries and hearing loss.
The inner ear controls the senses of both hearing and balance. As you can see, this important organ is in fact very tiny.
The final component is the inner ear, the transmission and broadcasting portion of the hearing process.

Our Outer (Pinna) and Middle Ear and Skull collect sound waves and conduct them to our organ of hearing, the cochlea. Within the cochlea, the mechanical energy is transformed into chemo-electrical signals that are transmitted via the Vestibular Nerve to the brain. If the ear drum is damaged, or the connection (joint) between these three bone become separated, or should any or all of these bones become damaged or diseased, a Conductive Hearing Loss occurs.
If a conductive loss is diagnosed, and the drum and bones of the middle ear be damaged, the ENT Surgeon may suggest a surgical procedure, termed a a€?Tympanoplastya€?. Due to technology advances in music players and cell phones, many people are delivering constant and loud energy levels to their cochleae.

Stapedectomy, and check out Stapedectomy on Wikipedia, Youtube, Google News, Google Books, and Twitter on Digplanet.
If the stapes footplate is fixed in position, rather than being normally mobile, then a conductive hearing loss results.
In both of these situations, it is possible to improve hearing by removing the stapes bone and replacing it with a micro prosthesis - a stapedectomy, or creating a small hole in the fixed stapes footplace and inserting a tiny, piston-like prosthesis - a stapedotomy.
Presence of active otosclerotic foci (otospongiosis) as evidenced by a positive flemmingo sign. When a stapedectomy is done in a middle ear with a congenitally fixed footplate, the results may be excellent but the risk of hearing damage is greater than when the stapes bone is removed and replaced (for otosclerosis). A modified stapes operation, called a stapedotomy, is thought by many otologic surgeons to be safer and reduce the chances of postoperative complications. Laser stapedotomy is a well-established surgical technique for treating conductive hearing loss due to otosclerosis.


Stapedotomy, like stapedectomy, can be successful in the presence of sclerotic adhesions (tissue growths abnormally linking the bones to the tympanic cavity), provided the adhesions are removed during surgery. Because it is a simpler and safer procedure, stapedotomy is normally preferred to stapedectomy in the absence of predictable complications. A bone-anchored hearing aid, or BAHA, is a surgically implanted device that is used for patients with certain types of hearing loss.
The BAHA has two major components - a titanium implant that is placed during a brief surgical procedure (less than one hour) and a special hearing aid that fits on the titanium implant. The BAHA hearing aid is a speech processor that sends vibrational energy to the titanium implant. The BAHA can overcome a problem of the middle or inner ear (due to multiple ear surgeries, a congenital abnormality or absence of the middle ear, or single sided deafness) and stimulates a functional inner ear (cochlea) directly. Above: The BAHA (placed behind the right ear in this image) transmits vibrational energy to a functioning inner ear (cochlea) when a pediatric or adult patient has conductive hearing loss that has not been reversible with middle ear surgery (cholesteatoma with damaged or absent ossicles, failed ossiculoplasty surgery, severe congenital aural atresia or abnormal ossicles). Above: This BAHA, placed behind a deaf left ear, can transmit vibrational energy to the normal functioning cochlea on the right side to improve sound localization and to enhance sound and speech perception.
These losses, however, are usually temporary and can be cleared up with correction of the condition. The repair of the ear drum (called tympanoplasty) is a common surgical avenue for restoration of hearing. Certain conditions may limit the actual movement of those bones, thus limiting the transmission of sound waves.
The main structure is the cochlea, a bone that is shaped much like a spiral seashell, and the semicircular canals which are further connected to the brain by the eighth nerve.

The information is provided with the understanding that ESIC is not engaged in rendering surgical or medical advice or recommendations. The ear drum absorbs this energy and transfers it into the MIDDLE EAR via a chain of tiny bones called the Ossicular Chain. If a person experiences a sudden onset hearing loss, a hearing professional should be seen, an Audiologist or an Ear, Nose, Throat Surgeon. It is felt that over time, these loud sound levels can damage the sensory neural component of hearing. The results of this surgery are generally most reliable in patients whose stapes has lost mobility because of otosclerosis. This is primarily due to the risk of additional anomalies being present in the congenitally abnormal ear. In stapedotomy, instead of removing the whole stapes footplate, a tiny hole is made in the footplate - either with a microdrill or with a laser,[3] and a prosthesis is placed to touch this area with movement of the tympanic membrane.
The procedure creates a tiny opening in the stapes (the smallest bone in the human body) in which to secure a prosthetic. Osseointegration allows a strong bond to develop between the implant and the bone, assuring that a very efficient transfer of sound energy occurs.


Patients with maximum conductive hearing loss in both ears can enjoy enhanced sound and speech perception compared to conventional hearing aids.
Other conditions such as bony growths in the ear canals (common to surfers) can result in much conductive hearing loss. The condition is called Congential Atresia and can also present some deformity of the external ear termed microtia. The cochlea contains nerve endings which deliver hearing impulses to the brain; the nerve endings of balance are in the semicircular canals. Any information in the publications, messages, postings or articles on the web site should not be considered a substitute for consultation with a board-certified otolaryngologist (ear, nose and throat specialist) to address individual medical needs. There are three bones making up this chain: The Malleus (Hammer), the Incus (Anvil) and the Stapes (Stirrup). Should you have any questions about any of the Invotec products shown in this website or a medical condition they address, always consult a physician or your healthcare provider.
The first is a disease process of abnormal mineralization of the temporal bone called otosclerosis. Nine out of ten patients who undergo the procedure will come out with significantly improved hearing while less than 1% will experience worsened hearing acuity or deafness.
If high pressure within the fluid compartment that lies just below the stapes footplate exists, then a perilymphatic gusher may occur when the stapes is removed. The CO2 laser allows the surgeon to create very small, precisely placed holes without increasing the temperature of the inner ear fluid by more than one degree, making this an extremely safe surgical solution. The stapedotomy method is not applicable in those relatively rare cases that involve scleroris of the entire ossicular chain. This process is called otosclerosis; the abnormal bone fixes the stapes in position, not allowing it to vibrate properly. The eighth nerve can be thought of as a communications cable connecting the receptors of the inner ear with the information processing centers of our internal computer, the brain. Individuals' particular facts and circumstances will determine the treatment which is most appropriate.
If you wish to see these implants, please see our online catalog for Total or Partial Ossicular Replacement Prostheses. Even without immediate complications during surgery, there is always concern of a perilymph fistula forming postoperatively.
Treatment can be completed in a single operation visit using anesthesia, normally followed by one or two nights' hospitalization with subsequent at-home recovery time a matter of days or weeks.
