We reported a 15-year-old male exhibiting middle ear malformation with meatal cholesteatoma who was treated by a transmastoid operation 5 years after a meatoplasty. He showed slight microtia, meatal stenosis of the cartilaginous portion, atresia plate, abnormally located facial nerve, hypoplasia of the tympanum, fusion of the malleus and incus, chorda tympani adjacent to the atresia plate, intact incudo-stapedial joint and marked improvement of mastoid aeration after meatoplasty.
Reconstruction of the opened cavity with an aural cartilage plate (attico-antromastoid reconstruction) was effective not only to obtain normal hearing and ear canal structure, but also to preserve mastoid aeration.
