A 30-year-old woman has a small attic cholesteatoma confined to the epitympanum with an intact ossicular chain and an air-bone gap of only 15 dB on the affected side. Which surgical procedure is specifically designed to exteriorize this disease while preserving her good hearing mechanism?

• A Bondy's modified radical mastoidectomy ✓
• B Radical mastoidectomy
• C Canal wall down mastoidectomy with obliteration
• D Cortical mastoidectomy with atticotomy

Explanation

Bondy's modified radical mastoidectomy removes the bridge and exteriorizes the diseased attic and antrum but deliberately leaves the undiseased mesotympanum and functioning ossicular chain untouched, so hearing is preserved without reconstruction. Classical radical mastoidectomy removes the posterior canal wall and converts the whole middle ear into an exteriorized cavity, sacrificing hearing. Cortical mastoidectomy does not address attic cholesteatoma adequately.
