title: [Methods for the surgical treatment of chronic sphenoiditis and ethmoiditis].
abstract: The objective of the present study was to design tools for the enhancement of safety of the surgical instruments used in the treatment of chronic sphenoiditis and ethmoiditis. The proposed instruments for endonasal surgery on sphenoidal sinuses and posterior cells of the ethmoidal labyrinth make it possible to improve the quality of surgical interventions, decrease their duration , and reduce the risk of damage to the important anatomical structures. The instruments were used for the surgical treatment of 120 patients that produced no complications. 98 patients were followed up for 3 years; five of them (5.2%) developed relapses compared with 38 (24.2%) patients operated by the traditional techniques. It is concluded that the proposed surgical instruments for the treatment of sphenoidal sinuses and posterior cells of the ethmoidal labyrinth help to increase the effectiveness and safety of surgical interventions on these structures.
