Silver Nasal Cartilage Chisel single guarded, 7.0 mm wide, 7″ (17.8 cm) is a unique tool used in nasal reconstructive operations. The instrument is primarily used during lateral osteotomies and nasal fractures. The wedge-shaped blade gives the surgeon extra control while the guard is used to give visual cues to the surgeon during the procedure. The osteotome is available curved right or left as well depending on surgical need.
