Nasal surgery punches designed to excise a segment of tissue (frequently in the form of a disc) from the ethmoid bone through the nose, usually to provide access to the paranasal ethmoid sinus. These punches are typically handheld, manual instruments with a cutting mechanism (e.g., two-part, movable) at the distal end, operated by manipulating an articulated handle. Dedicated ethmoid bone punches are available with the working end designed for straight, downward, or upward cutting.
