Siebenmann Frontal Sinus Cannula 2.5mm, 15cm

Clinical Application

This cannula is designed for controlled access to the frontal sinus for irrigation, lavage, aspiration and targeted delivery of therapeutic solutions during rhinologic procedures. Commonly used by otolaryngologists and rhinologists during functional endoscopic sinus surgery (FESS), frontal sinusotomy management, and intraoperative or postoperative washouts. The slim 2.5 mm lumen facilitates passage through narrow frontal recesses or through a trephination tract while permitting effective fluid exchange under endoscopic visualization.

Design & Configuration

The instrument’s 15 cm overall length provides sufficient reach from the external access point or transnasal entry to the frontal sinus cavity while maintaining shaft control for precise positioning. The small-diameter cannula balances flow and maneuverability—allowing irrigation and aspiration without excessive bulk that can obstruct endoscopic views or traumatize mucosa. The single-lumen cannula geometry supports controlled delivery or removal of fluids and is compatible with standard syringes or suction tubing where continuous or intermittent irrigation is required.
