Citelli antrum punch up cutt. bite 3.5mm

Clinical Application

This up-cutting antrum punch is designed for controlled removal of small segments of bone and soft tissue within the maxillary antrum and adjacent paranasal sinus spaces. It is used to create or enlarge an antrostomy, trim bony ostia, or excise targeted soft tissue during endoscopic sinus surgery, revision procedures, and select open antral approaches where precise, confined cutting is required.

Design & Configuration

The up-cutting geometry delivers a shearing action that directs the cutting force upward from the instrument tip. This configuration helps the surgeon achieve precise bites in a tight working corridor while minimizing downward traction on surrounding mucosa. The compact 3.5 mm bite allows controlled, incremental tissue or bone removal for accurate ostium sizing and contouring. A direct punch jaw interface provides secure apposition of tissue for predictable cutting and tactile feedback in confined anatomical spaces.
