Instruments and equipment for endoscopic sinus surgery.Otolaryngol Clin North Am. 1989 Aug; 22(4):703-11.OC
It is the fiberoptic endoscope and its related hardware that distinguish endoscopic sinus surgery from previous techniques. Lens angles of 0, 25, and 70 degrees, comprising a representative telescope set, accommodate virtually any endoscopic sinus procedure, diagnostic or therapeutic, with unsurpassed visualization. Each telescope may be fitted with an optional suction-irrigation adaptor, a highly controversial accessory among endoscopic surgeons. The clinical situation often dictates the optimal combination of equipment, anesthesia, and technique; surgeon's preference is equally influential. Mastery of conventional operative techniques combined with thorough endoscopic skills is essential for consistent, effective, and safe surgical performance.
