What is Ultrasonic Rhinoplasty?

An ultrasonic rhinoplasty uses an instrument called a piezotome to sculpt the nasal bones. This device uses ultrasonic energy to very precisely and gently reshape the bone. The ultrasonic energy is very specifically directed to the bone so that soft tissues are unaffected. This means that there is no collateral soft tissue damage resulting in improved healing times with minimal swelling and bruising. It avoids the use of coarse instruments such as  osteotomes( chisels) and hammers which can result in irregularities and unwanted fractures and splinters in the bone. This is a major advance in rhinoplasty techniques and is also applicable to preservation rhinoplasty techniques which aim to preserve and maintain structures in the nose by reshaping rather than using ablative or destructive techniques.    

"The SONOPET ultrasonic bone aspirator (Mutoh Co., Ltd., Tokyo, Japan)
utilizes ultrasonic waves to emulsify bone with concurrent irrigation
and suction, enabling precise, graded bone removal under direct
visualization without thermal or mechanical injury to the surrounding
soft tissue or mucosa."In our practice, we use rasps and other time tested conventional methods to remove a dorsal hump. We have no personal experience with this technology that has been available for over seven years.Thank you for your query.Dr Joseph

I believe you are referring to a method of removing bone when it is required.  Not many surgeons utilize this method as most are already skilled at more established and tested methods of performing this maneuver as part of their Rhinoplasty procedure.  I personally find the bone removal as the least complicated aspect of the procedure and adding technology where it is not needed simply adds cost and time to the surgery.
