True about tubercular otitis media are all except: (A) Spreads through Eustachian tube, (B) Causes painless ear discharge, (C) May cause multiple perforations, (D) Usually affects both ears
Answer is D. Tubercular otitis media In most of the cases, infection is secondary to pulmonary tuberculosis; infection reaches the middle ear through the eustachian tube. Perforation: Multiple perforations, 2 or 3 in number, are seen in pars tensa and form a classical sign of disease. These may coalesce into a single large perforation. Painless ear discharge: Earache is characteristically absent in cases of tubercular otitis media. Discharge is often foul-smelling because of the underlying bone destruction.
