  • Abstract
  • Look Inside

In a 16-year-old male with right hearing loss, ossicu-lar anomaly was suspected by audiological examination and CT findings. Exploratory tympanotomy revealedthat there was membranous tissue in the mesotympa-num. The long process of incus was not found. The sta-pes was deformed and separated from the footplate. Open type cholesteatoma was identified in the medial side of malleus handle and it was removed. The type Ⅳ tympanoplasty was performed and hearing was much improved. There was no anomaly in other area. The association of congenital cholesteatoma and ossicular anomaly was discussed with review of literature.
