The posterosuperior retraction pocket, if allowed to progress, will lead to:: (A) Sensorineural hearing loss, (B) Secondary cholesteatoma, (C) Tympanosclerosis, (D) Tertiary cholesteatoma
Answer is B. The option (b) should have been primary cholesteatoma and not secondary.Secondary cholesteatoma occurs due to migration of squamous epithelium through a preexisting perforation such as poslerosuperior marginal or total perforation (as occurs after acute necrotising otitis media). There is no term like tertiary cholesteatoma as given in option (d).
