A 42-year-old with a long-standing attic cholesteatoma develops disequilibrium when the ear is suctioned. CT shows erosion of the lateral semicircular canal, while hearing remains serviceable. There is no facial weakness or intracranial complication. What is the most appropriate management principle?
A lateral-canal fistula is an advanced complication. The operative plan must balance complete disease control against the risk of opening or destabilising the membranous labyrinth; this is not a routine office-management decision.
A. Otology-led definitive surgery planned to eradicate disease while protecting the labyrinth and residual hearing: A lateral-canal fistula is an advanced complication. The operative plan must balance complete disease control against the risk of opening or destabilising the membranous labyrinth; this is not a routine office-management decision.
B. Repeated microsuction and long-term observation: This does not control progressive destructive disease or protect against further labyrinthine, facial-nerve or intracranial complications.
C. Immediate labyrinthectomy: A destructive hearing-sacrificing procedure is not automatically justified when hearing is serviceable and disease may be managed with labyrinth-preserving technique.
D. Hearing aid fitting before considering surgery: Amplification may address disability but does not treat the erosive pathology.
E. Empirical systemic steroids: Steroids do not eradicate keratinising middle-ear disease.
If the ear were already profoundly deaf with extensive uncontrolled disease, a hearing-sacrificing approach might be discussed after specialist counselling.
