In the staging system for cholesteatoma (EAONO/JOS 2017 consensus), Stage III disease corresponds to:

• A Cholesteatoma confined to the primary site only
• B Cholesteatoma extended beyond the primary site but without complications or inner ear involvement
• C Bilateral cholesteatoma regardless of extent
• D Cholesteatoma with extension to a structure requiring specific surgical approach and/or with associated complication ✓

Explanation

The EAONO/JOS 2017 staging: Stage I = cholesteatoma confined to one site (primary site); Stage II = cholesteatoma in more than one site but without complications or inner ear involvement; Stage III = cholesteatoma with complications or requiring specific surgical approach (e.g., labyrinthine fistula, facial nerve involvement, intracranial extension); Stage IV = subtotally/totally resected cholesteatoma or bilateral. This staging guides surgical planning and expected outcomes.
