FESS Instrument Essentials: What Every ENT Surgeon Needs in the OR

ENT FESS Instrument Essentials: What Every ENT Surgeon Needs in the OR CincyMed Clinical Resource  ·  4 min read Functional endoscopic sinus surgery (FESS) demands a precisely configured instrument set to operate safely in the tight confines of the nasal cavity and paranasal sinuses. Mastery of FESS instruments — which instruments to use, when, and in what sequence — is as important as surgical anatomy knowledge in achieving complete disease clearance and avoiding orbital and intracranial complications. This guide covers the essential instrument categories every ENT surgeon should have available in the sinus surgery OR. FESS Instrument Categories: Essential Setup Instrument Category Examples Primary Function Key Specifications Sinuscope (Nasal Endoscope) 0°, 30°, 45°, 70° rigid endoscopes Illumination and visualization of sinuses 4 mm diameter; 18 cm working length; Hopkins rod-lens Through-Cutting Forceps Stammberger punch, Blakesley forceps (straight, upbiting, 45°, 90°) Tissue removal, polyp avulsion, ostium enlargement 2–4 mm jaw width; fenestrated or non-fenestrated jaw Curettes Ball-tipped, ring, and angled sinus curettes Disease removal from sinus walls; maxillary antrostomy 90°, 120° angled; blunt or sharp tip options Rongeurs Double-action rongeur; Kerrison rongeur (1–3 mm) Bone removal; ethmoid bulla takedown 1–3 mm bite; forward-cutting or upbiting Suction Tubes Frazier suction, angled sinus suction (Ferris-Smith, Cottle) Blood and fluid clearance; retraction; suction coagulation 2–4 mm diameter; 15–18 cm length; angled tip options Giraffe Forceps / Backbiting Forceps Backbiting ostrum forceps; angled Blakesley Reverse-direction tissue removal in maxillary sinus; posterior ethmoid 90° or 120° angled jaw; backbiting mechanism Seekers and Probes Ball-ended seeker; Kuhn seeker; frontal ostium probe Ostium identification; gentle tissue palpation without dissection 45° and 90° angled; 2 mm ball or olive tip The Sinuscope: Optic Selection for FESS The rigid sinuscope is the most critical FESS instrument — without reliable visualization, all other instruments are useless. The 0° endoscope provides the most intuitive straight-ahead view and is the standard for initial nasal cavity inspection, anterior ethmoidectomy, and sphenoidotomy. The 30° scope allows visualization around corners, particularly useful for maxillary antrostomy and inferior turbinate work. The 45° and 70° scopes are essential for complete frontal sinus and maxillary sinus surveillance, as well as postoperative cavity inspection. A 4 mm diameter, 18 cm length, 0° Hopkins rod-lens scope should be the foundation of every FESS instrument set. HD camera systems paired with high-flow light sources (xenon or LED, minimum 175W) provide the illumination necessary for precise dissection near the skull base and orbit. Through-Cutting Forceps: Clinical Applications Blakesley through-cutting forceps are the workhorses of FESS tissue removal. The straight Blakesley is used for anterior ethmoidectomy and nasal polyp avulsion; the upbiting 45° Blakesley is essential for extending posterior ethmoid dissection and taking down the ground lamella toward the sphenoid. The Stammberger punch is the instrument of choice for creating and enlarging the middle meatal antrostomy — its circular cutting mechanism removes a precise plug of tissue without tearing or lateral injury to the orbit. Always use through-cutting forceps to remove tissue rather than avulsing it with standard graspers. Avulsion near the skull base risks tearing the olfactory fila or entering the anterior skull base, with potentially catastrophic intracranial consequences.

Suction Management During FESS Hemorrhage control is the primary challenge in FESS — blood pooling in the nasal cavity can rapidly reduce visualization to zero, increasing complication risk. A high-caliber (3–4 mm) suction tube with reliable flow is an instrument as critical as any forceps. Cottonoid pledgets soaked in topical vasoconstrictor placed strategically at the start of the case, combined with active suction during dissection, are the keys to maintaining an operative field. Recommended Basic FESS Instrument Set 0° and 30° 4 mm Hopkins rod-lens sinuscopes Straight, 45° upbiting, and 90° Blakesley forceps Stammberger punch (left and right cutting) 2 mm and 3 mm Kerrison rongeurs Ball-ended seeker and frontal ostium probe Frazier suction 3 mm and 4 mm; angled sinus suction 90° and 120° angled curettes Backbiting forceps for maxillary work The American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) provides clinical practice guidelines for CRS surgical management that complement FESS instrument protocol development. Conclusion A comprehensive FESS instrument set combines high-quality optics, versatile through-cutting forceps in multiple angles, reliable suction, and bone-removing rongeurs and curettes sized for paranasal sinus anatomy. Investing in quality instruments in each category — particularly the sinuscope and through-cutting forceps — directly reduces operative time and complication risk in endoscopic sinus surgery.
