Kerrison Antrum Punch 5x5mm, shaft 85mm, 20cm

Clinical Application

This instrument is intended for controlled removal of small bone and soft-tissue fragments during paranasal sinus procedures. The 5 x 5 mm biting tip is sized for precise osteotomy and antrostomy work around the maxillary antrum and adjacent ethmoid air cells, enabling targeted bone resection through limited surgical corridors while minimizing collateral tissue trauma.

Design & Configuration

The relatively short 85 mm shaft provides targeted reach into the antral cavity while retaining tactile feedback and control at the handle. A 5 x 5 mm bite gives a predictable, rectangular bite profile useful for staged removal of cortical bone and thin lamellae. The 20 cm overall length balances intraoperative reach with ergonomic handling for both open and endoscopic-assisted sinonasal approaches.
