What is ossicular?

: a small bone or bony structure especially : any of three small bones of the middle ear including the malleus, incus, and stapes. Other Words from ossicle. ossicular \ ä-​ˈsik-​yə-​lər \ adjective.

What is ossicular reconstruction?

Ossicular chain reconstruction (also called middle ear bone surgery) can improve conductive hearing. In some cases, all three middle ear bones are replaced. During surgery, you will be given local anesthesia with sedation. Or you may receive general anesthesia. Middle ear bone surgery takes about 1 to 3 hours.

What is ossicular chain?

The ossicular chain consists of three bones; the malleus, incus, and stapes joined by two synovial joints, the incudomallear and incudostapedial joints.[1] Together, they comprise the primary sound-conduction apparatus to transmit vibratory stimulus from the tympanic membrane to the oval window.

What causes ossicular erosion in the middle ear?

The proposed mechanism for erosion is chronic middle ear inflammation following increased production of cytokines—TNF alpha, interleukin-2, fibroblast growth factor, and platelet derived growth factor. They all produce hypervascularisation, osteoclast activation and bone resorption which leads to ossicular damage.

Who are the patients of ossicular erosion study?

Patients between 12 and 60 years of age with a history of ear discharge with moderate conductive deafness (>40 dB HL) were included in the study. The patients were assessed of ossicular erosion by new classification of ossicular status which included remnant ossicles (M=Malleus, I=Incus, S=stapes, + =present, – =absent, p=partially eroded).

What does chronic otomastoiditis with ossicular erosions mean?

Chronic otomastoiditis with ossicular erosions, also known as non-cholesteatomatous ossicular erosions or post-inflammatory ossicular erosions, is defined by the erosive changes involving the ossicles in the absence of cholesteatoma in a patient with a history of chronic otomastoiditis.

What is the new classification of ossicular status?

The patients were assessed of ossicular erosion by new classification of ossicular status which included remnant ossicles (M=Malleus, I=Incus, S=stapes, + =present, – =absent, p=partially eroded). Out of 42 cases studied, Incus is always eroded partially or completely in equal cases.
