Kerrison Antrum Punch 4x4mm, shaft 85mm, 20cm

Clinical Application

Designed for controlled biting and removal of small segments of bone in the maxillary antrum and adjacent sinus corridors. The 4x4 mm bite size provides predictable, measured bone removal useful during procedures such as limited antral windowing, middle meatal antrostomy, and other otolaryngology or sinus surgeries where precise debridement of thin bony lamellae is required. The instrument's shaft length facilitates access to deep or narrow antral recesses while preserving visualization of the working tip.

Design & Configuration

The compact 4x4 mm tip produces a focused bite that helps minimize collateral bone loss while allowing efficient removal of bony margins and ledges. An 85 mm shaft provides reach into the antral cavity without excessive instrument bulk in the surgical field; the 20 cm overall length gives the clinician sufficient handle length for controlled manipulation and tactile feedback. The slender shaft geometry reduces obstruction in narrow endonasal or transoral approaches and aids in maintaining line-of-sight during targeted bone removal.
