Wiener Antrum Rasp 18cm

Clinical Application

This rasp is intended for controlled manual abrasion and contouring of bony edges within the maxillary antrum. It is commonly used during open antral approaches (e.g., Caldwell‑Luc procedures), adjunctive steps in sinus surgery, revision procedures where residual sharp spicules or irregular bony windows require smoothing, and in oral/maxillofacial work to refine osteotomies adjacent to the sinus. The instrument enables precise removal of small amounts of bone to produce a smooth margin and reduce tissue irritation from sharp edges.

Design & Configuration

An elongated hand rasp profile provides reach into the antral cavity while allowing the surgeon to apply controlled, tangential strokes. The rasp-style working surface converts manual strokes into abrasive action against bone, permitting gradual contouring rather than aggressive cutting. The 18 cm overall length balances intracavitary access with tactile control at the handle, facilitating work in deeper recesses without undue hand crossover. The simple, single-piece form factor supports reliable handling and straightforward cleaning.

Material & Construction

Constructed from surgical-grade stainless steel to withstand repeated sterilization cycles and maintain a consistent abrasive surface. The single-piece or welded construction (depending on manufacturing variant) is selected to minimize crevices and simplify cleaning. The abrasive rasp surface is engineered for controlled bone removal without the need for powered instruments.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison
