Definition : Snares designed to position and tighten fine-gauge flexible, adjustable, wire loops around a region of the ear canal or Eustachian tube tissue for mechanical resection. These devices typically consist of a hollow tubular structure (e.g., a cannula), with one or more adjustable wire loops that protrude at the working end; frequently they include a stationary loop and a sliding loop. A mechanism at the proximal end controls how much wire extends out of the channel and the movement of the sliding (cutting) loop; the handle is usually straight (e.g., Krause type) to the cannula. Ear (endaural) snares may be single-use or reusable; they are used mainly to remove polyps, tumors, and other abnormal tissue from the ear canal.
