title: [Extended trepanopuncture of the frontal sinuses (therapeutic and diagnostic opportunities)].
abstract: The authors describe the technique of extended trepanopuncture of the frontal sinuses and relevant equipment (updated trephine, 4.2 mm wide-lumen drainage cannula, double-lumen attachment for it). The procedure enabled performing endoscopical review of the frontal sinus cavity, biopsies and minor operations through the lumen of the drainage cannula. The double-lumen attachment served for lavage of the frontal sinuses in the frontonasal obstruction.
