[Main principles of functional intranasal surgery of paranasal sinuses].

The analysis of complications consequent to 200 endoscopic intranasal operations (computed tomography was performed preoperatively in 96 and was not performed in 104 patients) has shown that the incidence of serious complications in both groups was minimal and that of such complications as eyelid hematoma, neuralgia and hemorrhage was similar. Complication-safe operative procedure is described. It is believed that the absence of computed tomograms should not cause the change of functional intranasal surgery for radical surgery by external approach or common polypectomy.
