The Coakley Antrum Curette, Slight Curve, Large is a specialized surgical instrument used in otologic procedures, particularly in the treatment of conditions affecting the middle ear or mastoid antrum. The slight curve of the curette allows for precision in scraping or removing tissue from the antrum, a small cavity within the mastoid bone, which is often involved in chronic ear infections or surgical interventions such as mastoidectomies or tympanoplasties.
