The relationship between frontal sinus drainage and osteomeatal complex disease: a CT study in 217 patients.
Over a period of 2 years we reviewed the CT scans of 217 patients with recurrent sinusitis. Our findings revealed a number of cases of osteomeatal complex disease with no frontal sinus involvement. This result is difficult to reconcile with the concept of a common drainage in the middle meatus shared by the frontal and anterior ethmoid sinuses. We conclude that the frontal sinus drains separately from the other paranasal sinuses in a large percentage of cases, and that the frontal sinus is frequently spared when there is ethmoid or maxillary sinusitis.
