Punches, Surgical, Middle Ear
Definition : Surgical punches designed to excise a segment (frequently in the form of a disc) of the middle-ear tissue including the ossicles (e.g., stapes, tympanum). These devices are typically handheld, manual instruments with two blades ending in concentric sharp rings or cups that work together as a jaw at the distal end and scissors-like ring handles at an angle (e.g., 90 degrees) to the blades. Middle-ear punches are used in endaural surgical procedures including excision of the stapes (i.e., stapedectomy) and opening of attic and/or the mastoid antrum of the middle ear (i.e., atticotomy and atticoantrotomy, respectively)
