A 30-year-old woman has an attic cholesteatoma limited to the epitympanum with normal hearing and an intact tympanic membrane. Which operation removes the diseased attic and exteriorizes it into the external canal while deliberately leaving the tympanic membrane and ossicular chain undisturbed?

• A Combined approach tympanoplasty
• B Radical mastoidectomy
• C Atticoantrostomy with canal wall reconstruction
• D Bondy's modified radical mastoidectomy ✓

Explanation

Bondy's operation is a modified radical mastoidectomy performed for an attic cholesteatoma in a hearing ear: the cholesteatoma is exteriorized by opening the attic and antrum, but the healthy tympanic membrane and intact ossicular chain are left untouched, preserving the existing hearing. D standard modified radical or radical procedure would sacrifice these structures, and combined approach tympanoplasty keeps the canal wall closed.
