Tympanocentesis and bacterial cultures of middle ear fluid should be performed in children with chronic otitis media refractory to antibiotic treatment. This requires technical expertise.

Sinus fluid should be obtained and sent for bacterial culture if the sinusitis is refractory to antibiotic treatment.

Upper respiratory tract cultures are not reliable in determining infection because of the high rate of asymptomatic children carrying S pneumoniae.
