Ossiculoplasty in often performed in conjunction to Timpanoplasty to repair the damaged ear bones or ossicles. Damaged Ossicles can lead to hearing loss. Ossiculoplasty is done with the help of carefully designed artificial bones. This is done either through incision hidden behind the ear or through one made in the ear canal.
Length of Ossiculoplasty
It normally takes a day to fully discharge the patient undergoing Ossiculoplasty.
For many years surgical treatment was instituted in middle ear diseases primarily to restore sound conduction, to control infection and to prevent serious complications. Changes in surgical techniques now have made it possible to reconstruct the diseased hearing mechanism in most cases. Various tissue grafts may be used to replace or repair the eardrum. A diseased ear bone may be replaced by middle ear prosthesis. Middle ear diseases can be treated using various types of surgical treatment/procedures like as Ossiculoplasty, Stapedioplasty, and Myringoplasty.
The goal of surgical treatment is better hearing, most typically for conversational speech. Ossiculoplasty/Stapedioplasty surgery is being performed to improve or to maintain the conductive portion of hearing loss. The aim of ossiculoplasty/stapedioplasty surgery is to reconstruct the malfunctioning ossicular chain (chain of three bones i.e. Malleus, Incus & Stapes) in the middle ear cavity. Myringoplasty surgery is performed to ventilate the middle ear, to prevent fluid from building up and to prevent infections in the middle ear cavity. All the above mentioned surgical procedures take about an hour’s time and in most cases patients are discharged after 24-36 hours.
During the 1960’s in the earliest stage of the development of surgical treatments, attempts were made to use biological materials such as cartilage or the remnants of the ossicular chain to create ossicular replacements. Such materials were termed auto-graft and homo-grafts materials since they were obtained from the person and donor respectively receiving the treatment.
Work in developing superior implant materials was continued until the 1970’s, when bioactive materials were developed. Their name comes from their chemical structure, which promotes chemical adhesion between the tissue and the implant, effectively eliminating the need for Auto- and Homo- Grafts.
From 1970 to up till now, various types of material have been using for ossicular chain reconstruction like as Gold, Stainless Steel, Platinum, Hydroxyapatite, Teflon, Polyethylene, Glass Ionomer Cement, and Titanium.
But recently the new trend starts to perform surgery of Ossiculoplasty, Stapedioplasty, and Myringoplasty with Titanium based Middle ear implants. Titanium implants are extensively used in cardiovascular, spinal surgery, orthopedic and dental surgery as well as in reconstructive and plastic surgery.
Side Effects of Ossiculoplasty
A successful Ossiculoplasty always repairs hearing, though the extent of it depends on the extent of damage and the type of artificial bones used. There can be some amount of bleeding from the incision for the first few days. Side effects of Ossiculoplasty such as increasing hearing loss, pain, and discharge from ear, fever and dizziness, one should immediately consult the doctor.
