A new instrument for rhinoplasty: the osteotome with protector and internal guide

Overview

Taking down a nasal hump requires cutting bone and cartilage to an exact depth by feel. Too much leaves a scooped bridge; too little leaves the hump. The authors present a modified osteotome whose guard and internal guide are meant to control the depth and direction of the cut.

Sections of note

• Instrument description; no series, measurements, complication rates or comparison with a standard osteotome are stated in the abstract.
• Rhinoplasty is characterized as demanding high intraoperative precision and control.
• Hump reduction is described as the most common maneuver in aesthetic rhinoplasty and also the most sophisticated, dangerous and difficult to learn.
• The osteotome has a protector and an internal guide.
• The stated aim is accurate hump reduction in a safe, easy and gentle manner.

What it means for a patient

• Surgeons continue to refine the tools for hump removal because the step is hard to judge and errors are hard to reverse.
• The abstract gives no evidence that this instrument produces smoother bridges or fewer revisions than standard chisels.
• Ask what technique and instruments a surgeon uses for hump reduction; several exist, including rasps, chisels and ultrasonic devices.

Why this paper matters

Hump reduction errors are a leading cause of revision, and this instrument is one of many attempts to make the cut reproducible. It sits alongside ultrasonic bone tools introduced in the same period. Clinical results with the device are not reported in the abstract.

Terms

• Osteotome: a chisel used to cut bone.
• Hump reduction: removing the bump of bone and cartilage on the bridge.
• Protector: a guard on the instrument that shields surrounding tissue from the blade.
• Internal guide: a built-in element that steers the blade along the intended path.
• Dorsum: the bridge of the nose.
• Intraoperative: during the operation.
