Nasal surgery punches designed to excise a segment of tissue (frequently in the form of a disc) from tissue surrounding one of the paranasal sinuses. These devices are typically handheld, manual instruments with a sliding, rotary punching mechanism at the working end, operated by squeezing a two-part handle configured at a right angle to the punching mechanism. Dedicated nasal punches are available with appropriate characteristics for perforating each of the paranasal sinuses (i.e., frontal, sphenoidal, ethmoidal, maxillary).
