The Boucheron Speculum Set of 4 (Large Round) is a set of otologic instruments designed for examining the ear canal and middle ear during diagnostic or surgical procedures. The set includes four speculums of varying sizes, with the large round design providing optimal exposure of the ear canal for procedures such as ear examinations, earwax removal, tympanoplasty, or mastoidectomy. The large size ensures easy visualization and access, while the round shape is gentle on the ear canal.
