Use of the ultrasonic bone aspirator for lateral osteotomies in rhinoplasty

Overview

Lateral osteotomies, the cuts that let the nasal bones be narrowed, are usually made with a chisel and mallet, which can bruise soft tissue and shift the framework. The authors describe cutting the bone instead with an ultrasonic device that removes bone without mechanical force, in a first small series.

Sections of note

• Series of 5 consecutive patients; level of evidence IV.
• Device: ultrasonic bone aspirator, reported as a novel use for lateral osteotomies.
• Stated benefits: avoidance of soft tissue and mucosal injury, minimal bleeding and bruising, and no mechanical force that could destabilize the bony or cartilaginous framework.
• The authors call for further investigation.
• The abstract reports no measurements of bruising, no follow-up length and no outcome scores.

What it means for a patient

• Some surgeons now cut the nasal bones with an ultrasonic tool rather than a chisel, aiming for less bruising and more control.
• The evidence here is five patients and the surgeons' impression; no comparison with chisels was made.
• The technique needs wider exposure of the bone, which the abstract does not discuss.

Why this paper matters

It is an early US report of ultrasonic lateral osteotomy, which grew into the piezoelectric rhinoplasty movement. Randomized comparison with conventional osteotomes came later and is not part of this paper.

Terms

• Lateral osteotomy: the bone cut along the side of the nose at its junction with the cheek, used to narrow the nose.
• Ultrasonic bone aspirator: a powered tip that vibrates at ultrasonic frequency to remove bone while suctioning debris.
• Osteotome: a chisel used to cut bone.
• Mucosa: the moist lining inside the nose.
• Ecchymosis: bruising.
• Level IV evidence: a case series without a comparison group.
