Types of Tympanoplasty | Medicalalgorithms.com

A tympanoplasty is classified based on the extent of surgery required.

NOTE: These types overlap with the classification for cholesteatoma in the previous section.

Ossicles of the middle ear:

(1) malleolus (on the tympanic membrane)

(2) incus

(3) stapes (with footplate in the fenestra vestibuli)

where:

• A normal ossicle is one that is intact and mobile.

• In a Type Vb tympanoplasty the stapes is removed (stapedectomy).

• In a Type Va tympanoplasty a new opening is made in the horizontal semicircular canal.
