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.
