The 6 1/4" House Knife (Right, 7mm) is a specialized surgical instrument primarily used in otologic surgeries, particularly for procedures involving the middle ear or mastoid area. The 7mm blade allows for precise dissection and cutting of soft tissue or bone. The right-angled design makes it especially useful for accessing and working in difficult-to-reach areas around the ear or temporal bone during surgeries such as mastoidectomy or tympanoplasty.
