Kerrison Antrum Punch 6x6mm, shaft 85mm, 20cm

Clinical Application

Designed for controlled bone removal during otolaryngology and sinus procedures, this Kerrison antrum punch is optimized for creating or enlarging antrostomies, removing thin bony partitions of the maxillary antrum, and trimming bony ledges encountered during endoscopic sinus surgery. The 6x6 mm bite size allows predictable, incremental excision of bone while minimizing collateral soft-tissue trauma—useful for surgeon-directed bone removal in narrow anatomic corridors.

Design & Configuration

The instrument’s 85 mm shaft provides extended reach into the nasal cavity and maxillary antrum while keeping the surgeon’s hand a comfortable distance from the operative field (20 cm overall length). The compact 6x6 mm biting window delivers a small, well-defined specimen with each closure, improving control when working adjacent to mucosa, orbital floor, or thin lamellae. A slim shaft profile facilitates access through endonasal portals and reduces obstruction of endoscopic visualization.
