Ossiculoplasty is a surgical process wherein there is reconstruction of the ossicular chain in the ear. Ossicular chain in a normal person, is formed by three tiny bones called malleus, incus and stapes placed in the middle ear. The malleus is attached to the ear drum on one end and to the incus, at the other end. The incus connects the other two bones. The stapes connects the incus to the oval window of the inner ear. The function of these three ear ossicles is to transmit sound waves from the ear drum to the fluid in the inner ear. When these small bones get damaged, then hearing is drastically affected and leads to conductive hearing loss. Hence their repair or reconstruction is most important for restoring normal hearing.

Eardrum repair?
DefinitionEardrum repair, called tympanoplasty, is a procedure to correct a tear in the eardrum (tympanic membrane). Ossiculoplasty is the repair of the small bones in the middle ear.Alternative NamesTympanoplasty; Ossiculoplasty; Ossicular reconstructionDescriptionUsing general anesthesia, an ear-nose-throat (ENT) specialist grafts a small patch from a vein or fascia (muscle sheath) onto the eardrum to repair the tear.For problems with the small bones (ossicles), the surgeon will use an operating microscope to view and repair this chain of small bones using plastic artificial bones or ossicles from a donor.Why the Procedure Is PerformedA number of problems can permanently damage your eardrum (tympanic membrane) or harm the very small bones (ossicles) that are right behind the eardrum. These problems include chronic ear infections, trauma, cancer, and cholesteatoma.This damage may cause hearing loss, pain, or an infection that does not go away.If antibiotics or other treatments do not heal chronic ear infections, then surgical eardrum repair may be necessary.RisksRisks for any surgery are:BleedingInfectionProblems breathingReactions to medicationsAdditional risks include:Complete less of hearingDamage to the facial nerve or nerve controlling the sense of tasteDamage to the small bones in the middle ear, causing hearing lossDizziness or vertigoIncomplete healing of the hole in the eardrumBefore the ProcedureAlways tell your doctor or nurse:What allergies you may have to any medications, latex, tape, or skin cleanserWhat drugs you are taking, including herbs, herbs, and vitamins you bought without a prescriptionOn the day of the surgery:Take only a small sip of water with any drugs your doctor has prescribedTell your doctor if you have signs of illness or infectionYou will usually be asked not to drink or eat anything after midnight the night before surgeryYour doctor or nurse will tell you when to arrive at the hospitalAfter the ProcedurePatients usually leave the hospital the same day as the surgery. It is important to avoid water in the ear. There are sometimes stitches behind the ear for the first week and packing material in the ear. Your health care provider may recommend the use of a hair cap when showering for a few weeks after the procedure. Outlook (Prognosis)In most cases, the operation relieves pain and infection symptoms completely. Hearing loss is minor. The outcome may not be as good if the bones in the middle ear need reconstruction along with the eardrum.ReferencesJavia LR, Ruckenstein, MJ. Ossiculoplasty.
