Williams Antrum Rasp Archives

The Williams Antrum Rasp is a specialized surgical rasp designed for smoothing and enlarging the opening (ostium) of the maxillary sinus or for contouring bone within the sinus cavity during procedures like a Caldwell-Luc operation or endoscopic sinus surgery. Its long, slender shaft and small, often angled, rasping head allow it to reach into the sinus through a nasal or oral approach to remove bony obstructions and create a smooth, patent drainage pathway.

Key Features:

Long, slender shaft for accessing the maxillary sinus through nasal or oral routes.
Small, angled rasping head for smoothing bone and enlarging the sinus ostium.
Used in procedures to treat chronic sinusitis or to prepare the sinus for implantation.
Allows for controlled bone removal in a confined, delicate anatomical space.
Essential for functional endoscopic sinus surgery (FESS) and maxillofacial reconstruction.
Durable construction for precise work within the paranasal sinuses.
