Mastoid chisel

A mastoid chisel is a surgical tool designed for ENT procedures, specifically to precisely cut and shape the mastoid process—the bony area behind the ear. Surgeons use it to access or modify this region during operations like mastoidectomy or middle ear surgery, striking the instrument with a mallet to achieve controlled bone removal.

These reusable stainless steel instruments are typically classified as surgical tools and regulated under general medical device standards. They are supplied sterile or prepped for reuse, often as part of a surgical set, and must meet safety and performance requirements for surgical precision and durability.
