1. A 35-year-old man presents with progressive unilateral conductive hearing loss, absent stapedial reflex on the affected side, and a normal tympanic membrane on otoscopy. Tuning fork tests show Rinne negative and Weber lateralising to the affected ear. Which ossicular chain abnormality is most consistent with this picture?
2. A 45-year-old woman is diagnosed with chronic suppurative otitis media with cholesteatoma in the right ear. Intraoperatively, the surgeon finds a pearly white mass eroding into the tegmen. Which complication is being directly threatened by this erosion?

A 55-year-old diabetic man presents with left ear pain disproportionate to local findings, granulation tissue at the bony cartilaginous junction of the external auditory canal, and ESR of 110 mm/hr.
