The Shambaugh Narrow Elevator 3.5mm Blade is a specialized surgical instrument used primarily in ENT (ear, nose, and throat) surgeries. It features a 3.5mm narrow blade, designed for precise dissection and elevation of tissues in tight or delicate areas. The narrow design allows the surgeon to maneuver more easily in confined spaces, such as in the mastoid area during mastoidectomy or other middle ear surgeries.
