Knives, Surgical, Middle Ear, Myringotomy
Definition : Middle-ear surgical knives designed to incise the tympanic membrane by creating a small hole (i.e., myringotomy or tympanometry). These knives consist of manual, slender, handheld instruments with a flat or rounded handle and a long, extremely fine curved shaft which ends in a sharp, frequently triangular cutting edge. Myringotomy knives are used in surgical procedures performed for treatment of otitis media; they are intended to relieve pressure caused by the excessive buildup of fluid or to drain pus.
