[Sinus endoscopy in the diagnosis of rhinosinal pathology]

Findings in 86 endoscopic examinations of the nose and paranasal sinuses were compared with clinical and radiographic signs. Precise evaluations of endomaxillary lesions, including analysis of secretions, and histologic examinations were conducted. Clinical and endoscopic findings failed to concord in 28 p. cent of cases, and radiological and endoscopic images in 26 p. cent of cases, the majority of these errors arising because of homogeneous total filling of the sinuses. In spite of these divergences, endoscopy is relatively non-invasive and simple to perform, and occupies a place of choice in the diagnosis of disorders of the nose and sinuses. Sinus endoscopy can also be of therapeutic value, particularly for aeration of the sinuses and during minor surgical procedures.
