Sinobronchial syndrome (SBS) frequently associated with developmental deficiency of frontal sinuses. We evaluated,36 SBS patients and 178 controls who underwent simple 3way parasinus roentgen examination. Developmental deficiency of frontal sinuses was seen in 72.2% of the SBS patients, and 25.0% in the control group. Now SBS is believed to be caused by some dysfunction of the ciliary transport system in the respiratory tract. The dysfunction of the ciliary trasport system may be independent of the developmental deficiency of frontal sinuses.
