Nasal septum osteotome.
A new chisel for nasal septum osteotomy in craniofacial surgery is reported. With the aid of a guide wire, the cranial base is completely protected from inadvertent penetration. The direction of osteotomy can be changed because of the chisel's central fenestration, even if placed incorrectly at the beginning.
