Cosmetic surgeons performing rhinoplasty could make use of sound waves to avoid any damage to a patient's skin or soft tissue.
This is according to research from the Thomas Jefferson University Hospital in Philadelphia, where doctors conducted a retrospective study of 103 patients who underwent conventional rhinoplasty as well as aesthetic refinement procedures. Sound waves which were generated by an ultrasonic bone aspirator were used in every case.
The doctors say the device can be used to minimise the risk in operations to and around the nasal bones.
Sound waves allowed the surgeons to perform exact, graded removal of bone and no injuries to patients' skin or soft tissue were recorded in any operation.
"Multiple applications in nasal surgery can be found and although long-term results are lacking, the device's positive safety profile and early results warrant further use and investigation," said the researchers.
Data from the British Association of Aesthetic Plastic Surgeons shows that 4,207 patients had rhinoplasty procedures in 2010.
