Sinusitis in childhood.

There is much to be learned about sinusitis in children. The appropriate choice and timing of diagnostic tests, correct type and duration of antibiotic treatment, role of allergy management and adjuvant drugs, and indications for and limits of endoscopic sinus surgery remain to be defined. Technological advances have been introduced and accepted as standard with little validation. Well-thought-out, controlled studies of diagnostic and treatment modalities are needed to address these issues and to better understand the function of the sinuses in health and illness.
