The Coakley Antrum Curette, Acute Angled, Large is a surgical instrument used in otologic surgeries, particularly for procedures involving the mastoid antrum. The acute angle of the curette allows for precise tissue removal from more difficult-to-reach areas within the middle ear and mastoid cavity. This design is especially beneficial in mastoidectomy and tympanoplasty procedures, where accessing and cleaning the antrum or mastoid air cells is critical.
