[Computerized tomography in diseases of the frontal sinus]

Thirty-seven patients (15 women and 22 men), aged 22 to 67 years, with various frontal sinus pathologies were examined. The pathology was unilateral in all the patients. The following pathologies were identified: mucocele of frontal sinuses--2 cases; mucocele of the frontoethmoid area--4 cases; acute frontitis--5 cases; exacerbation of chronic frontitis (state after frontoethmoid trepanation)--14 cases; suppurative hemisinusitis--7 cases; frontal sinus cyst--2 cases; frontal sinus osteoma--3 cases. Final diagnosis was made with the aid of computer tomography because routine tomography proved inadequate. Computer tomography made it possible to clarify the state of the posterior and upper walls of the frontal sinus in the case of inflammation, mucocele, cysts, and osteomas and thus helped to elaborate adequate conservative or surgical therapy.
