Abstract: A surgical instrument for the removal of frontal nasal recess cells includes an elongate handle, a first arm extending from a first end of the handle and a second arm extending from a second end of the handle. The first and second arms can extend in opposing directions. Each of the arms include a spherical terminal hub on their respective ends. A plurality of cylindrical fingers extend from each terminal hub at an angle, thereby providing an umbrella-like configuration. A spherical cap is attached to a free end of each cylindrical finger.

Abstract: The uncinectomy knife is a surgical knife for performing uncinectomies and other sinus or endoscopic procedures. The uncinectomy knife has a central elongated handle having opposing first and second ends. The knife has a horizontally oriented cutting blade extending orthogonally from the first end of the handle and a vertically oriented cutting blade extending orthogonally from the second end of the handle. Both of the blades may be double-edged so that they can cut when the handle is moved in opposite directions. Both ends of each blade may terminate in a bulbous tip having a smooth, blunted surface, such as a sphere or rounded ball to prevent tissue trauma when the blade ends contact tissue. Accordingly, the uncinectomy knife may be inserted into tight cavities for tissue augmentation or removal without damaging the surrounding tissue.
