Citelli antrum punch up cutt. bite 4.0mm

Clinical Application

Designed to create a controlled fenestration into the maxillary antrum, this up‑cut punch is used in otolaryngology procedures where a precise circular opening is required. Typical applications include endoscopic or limited transantral access for drainage, debridement of diseased mucosa, or creation of a working portal during maxillary sinus surgery. The 4.0 mm bite size provides a predictable aperture appropriate for introducing suction, irrigation, or small instruments while minimizing excess tissue removal.

Design & Configuration

The up‑cut jaw orientation cuts on the upward stroke, which helps produce a clean core and reduces the tendency to push tissue deeper into the sinus cavity. A compact 4.0 mm cutting diameter offers controlled, repeatable excisions that preserve surrounding structures. The punch geometry is intended to concentrate force at the cutting rim for effective capture of mucosal and thin bony tissue with minimal collateral trauma.
