[Retrospective analysis of diagnostic and therapeutic results in patients with inflammatory diseases of the frontal sinus].

The diagnosis, clinical course and therapy of inflammatory diseases of frontal sinuses of 213 patients, aged 14 to 80 years, were investigated. In 104 patients the process was acute and in 109 patients it was chronic. 63% of patients suffered from purulent, 15% of them--from catarrhal, and 21.6% of them--from purulent-polypous frontal sinusitis 89.2% of patients showed unilateral and 10.8% of them bilateral lesions; 47.4% of patients displayed combined lesions of paranasal sinuses. For diagnostic and therapeutic purposesal 23.5% of patients were exposed to sinusal catheterization and irrigation according to the method of E.A. Landsberg; 7.5% of patients--to trepanopuncture, and 50.7% of patients--to frontotomy. 48.1% of operated patients developed relapses. After conservative treatment, which included catheterization and irrigation of frontal sinuses, relapses were seen only in 2.1% of patients. Our analysis demonstrated advantages of endonasal catherization of frontal sinuses in the diagnosis and therapy of frontal sinusitis and gave evidence that the manipulation was possible and safe in essentially all the patients treated.
