What is ossicular chain replacement?
Ossicular chain reconstruction (also called middle ear bone surgery) can improve conductive hearing. It can be done to replace a damaged malleus or incus bone. During surgery, you will be given local anesthesia with sedation.
What is total ossicular replacement prosthesis?
A total ossicular replacement prosthesis (TORP) is an alternative used especially when the superstructures of the stapes are damaged or completely missing. In this procedure, the stapes footplate is connected directly to the tympanic membrane (TM) and/or to the malleus (Fig. 1C).
How long does ossicular chain reconstruction last?
The procedure for ossiculoplasty takes place under general anesthesia and takes approximately one to two hours.
What does Ossiculoplasty mean?
Introduction. Ossiculoplasty is the reconstruction of the middle ear ossicular chain which has been disrupted or destroyed, by the use of some interpositioned devices which helps in regaining the original mechanics of the ossicular chain to transfer the sound energy to the inner ear.
Where is the ossicular chain located?
the middle ear
The ossicles are situated in the middle ear and suspended by ligaments. They articulate with each other through synovial joints to form a chain across the length of the middle ear from the tympanic membrane (laterally) to the oval window (medially).
What causes ossicular discontinuity?
OSSICULAR CHAIN DISCONTINUITY IS CAUSED BY: A fracture in the temporal bone — the bones at the side or base of the skull. Chronic ear infections such as otitis media. Cholesteatoma — a benign tumor caused by the build-up of skin cells and protein from the ear canal behind the eardrum.
What is Torp operation?
A transurethral resection of the prostate (TURP) is a surgical procedure that involves cutting away a section of the prostate. The prostate is a small gland in the pelvis only found in men.
What is Torp in ear?
Total ossicular replacement prostheses (TORP) are often used to re-establish ossicular coupling of sound in an ear lacking a stapes supra-structure. The use of TORPs, however, is associated with a 2/3 five year failure rate due to their anatomic instability over time in the middle ear.
Is ossicular chain reconstruction painful?
Pain is relatively mild (Pain Score: 3/10 for the first 3 days), but this will resolve gradually over the next 5 days. The ear bandage may be removed 2 days after surgery. Any sutures used are absorbable and do not need removal. Hearing gradually improves over several weeks.
What is ossicular discontinuity?
Ossicular discontinuity (OD) is a separation of the middle ear ossicles that can occur at one of the joints or within a bone (e.g. fracture).
Where is the malleus incus and stapes located?
The middle ear
The middle ear consists of the tympanic membrane and the bony ossicles called the malleus, incus, and stapes. These three ossicles connect the tympanic membrane to the inner ear allowing for the transmission of sound waves.
