Wiener Antrum Rasp 18cm

Clinical Application

This rasp is intended for controlled removal and contouring of bone within the maxillary antrum and adjacent paranasal sinus corridors. It is commonly used in otolaryngology procedures such as antral window creation, ostium enlargement, and limited bone smoothing during Caldwell‑Luc approaches or endoscopic-assisted antral access. The instrument facilitates tactile, incremental bone removal where precision shaping is required to preserve surrounding mucosa and landmarks.

Design & Configuration

The elongated 18 cm shaft provides adequate working length to reach the maxillary antrostomy site through intraoral or transnasal approaches while maintaining surgeon control. The rasping surface is designed for gradual bone abrasion rather than bulk cutting, allowing for controlled thinning and smoothing of bony edges. The single-ended, hand-held configuration delivers direct tactile feedback to the operator, which aids in preventing over‑resection and protecting soft tissues in confined sinus anatomy.
