In chronic suppurative otitis media, the type of perforation that is considered 'safe' (tubotympanic) is characteristically:
- A Central perforation that does not touch the annulus ✓
- B Attic perforation with granulations
- C Posterior-superior marginal perforation
- D Total perforation with cholesteatoma
Correct answer: A. Central perforation that does not touch the annulus
Explanation
The tubotympanic (mucosal) type of CSOM is characterised by a central perforation that does not involve the annulus fibrosis. It is considered 'safe' because there is no bone erosion or cholesteatoma, and complications are rare. Marginal and attic perforations are associated with the 'unsafe' atticoantral type.
