Joseph Nasal Knife — Short Straight Osteotomy Marker

Joseph Nasal Knife — Short Straight Marker

Joseph’s short straight nasal knife is the instrument with which the osteotomy line is marked on the bone before the saw or osteotome is brought into the wound. The 8-millimetre rigid blade scores the periosteum along the planned cut so the saw teeth engage a defined groove rather than skipping along the polished bone surface — the small detail that distinguishes a clean osteotomy from a comminuted one.

Periosteal scoring and what it buys

Marking the periosteum with a knife before sawing is not strictly required by modern technique, but in revision rhinoplasty where the bone has been operated on once and the surface is irregular it converts a difficult osteotomy into a reproducible one. The Joseph short knife reaches the bone through the same stab incision the saw will use; no additional approach is required.

The rigid blade

A flexible blade folds against the bone and the score becomes superficial; the Joseph knife is built rigid specifically to resist this — the cortex is scored to bleeding-point depth without operator over-pressure.
