Wiener Antrum Rasp Archives

The Wiener Antrum Rasp is a specialized ENT (Otolaryngology) instrument designed for smoothing and enlarging the opening of the maxillary sinus (antrum) during functional endoscopic sinus surgery (FESS). Its long, slender shank and curved, abrasive tip allow surgeons to reach into the sinus cavity through the nasal passage to file away bony obstructions or enlarge the natural ostium. This facilitates better drainage and ventilation of the sinus, which is a key principle in treating chronic sinusitis. The rasp provides controlled bone removal with minimal trauma to the surrounding delicate sinus mucosa.

Key Features:

Long, slender shank with a curved, abrasive tip for access to the maxillary sinus.
Designed specifically for enlarging and smoothing the maxillary sinus ostium during FESS.
Allows for controlled removal of bony obstructions to improve sinus drainage.
Minimizes trauma to the surrounding sinus lining (mucosa).
Essential for otolaryngologists performing endoscopic sinus surgery.
A precise tool for restoring normal sinus function in chronic sinusitis patients.
