Wullstein Classification of Tympanoplasty

Wullstein Classification of Tympanoplasty

Type I Tympanoplasty

Involves reconstruction of a new tympanic membrane in situations with a normal ossicular chain; recreates the middle ear space nearly exactly to its native size and geometry

Type II Tympanoplasty

Involves reconstruction of a new tympanic membrane in situations where the malleus is partially eroded; the new tympanic membrane is coupled with or without the malleus remnant to the native incus

Type III Tympanoplasty

Involves reconstruction of a new tympanic membrane in situations involving defects of the malleus and incus; the new tympanic membrane is coupled to the capitulum of the stapes

Type IV Tympanoplasty

Involves reconstruction of a new tympanic membrane and establishment of ossicular coupling to a mobile stapes footplate with absent crura; the new tympanic membrane is coupled to the footplate of the stapes

Type V Tympanoplasty

Involves reconstruction of a new tympanic membrane and establishment of ossicular coupling to the scala vestibuli in situations involving a fixed stapedial footplate; creation of a fenestra novovalis is necessary; this may also be termed malleovestibulopexy
