The Wullstein classification of tympanoplasty is based on:
- A Size and location of tympanic membrane perforation
- B The relationship between the reconstructed tympanic membrane and the stapes footplate/oval window ✓
- C Type of ossicular chain reconstruction performed
- D The graft material used for repair
Correct answer: B. The relationship between the reconstructed tympanic membrane and the stapes footplate/oval window
Explanation
Wullstein's classification (Types I–V) categorizes tympanoplasty based on the anatomical relationship between the reconstructed neotympanum and the functional window (oval or round window). Type I is simple myringoplasty; Types II–IV involve progressively more extensive ossicular reconstruction or direct coupling to the oval/round window. The classification reflects functional reconstruction of the sound transformer mechanism, not simply perforation size or graft material.
