Which rongeurs is used to expand the antrostomy in a Caldwell-Lub procedure?

The Kerrison rongeur is specifically designed for precise, controlled bite and removal of bone in delicate procedures, making it particularly suitable for expanding the antrostomy in a Caldwell-Luc procedure. This procedure typically requires carefully enlarging access to the maxillary sinus, and the Kerrison rongeur's design allows the surgeon to operate within the confines of the anatomy without damaging surrounding structures. Its angled jaws enable effective manipulation and access to specific areas, which is crucial in this type of surgical intervention. The Kerrison rongeur's capability to provide a secure grip on bone tissue while providing a clean and efficient removal process enhances its utility in such procedures.

Other instruments, like the Cushing rongeur, are designed for different purposes, primarily focused on soft tissue, and may not offer the necessary bone removal capability required in sinus surgery. The Bethune rongeur is often used in other contexts, such as orthopedic surgery, and may not provide the right access or function required for the antrostomy. The Stille-Leur rongeur, while versatile, does not have the pinpoint accuracy and control offered by the Kerrison rongeur that’s crucial when working in the intricate areas of the paranasal sinuses. Thus,
