PIEZOELECTRIC (ULTRASONIC) SURGERY
During rhinoplasty surgery, in order to reduce the large noses, to narrow the wide noses or to correct the curved noses, the bone roof constituting the upper part of the nose should be reduced and / or reshaped by cutting.
Since the beginning of the nasal plastic surgery, the use of mechanical hand tools such as hammers, chisels and rasps, which are used to change the shape of nasal bones, is still widely used today. In addition, motor devices have recently been introduced, allowing more precise cutting and shaping of bones.
Motorized devices can move forward-backward, circular or right-left directions, and that assure of work to work more accurately than mechanical tools. However, during the use of these devices, negative results such as tissue damage due to overheating of the bone, loss of touch sensitivity of the surgeon and soft tissue damage due to difficulties in determining the depth of cut can be observed.
This device was first used in the field of jaw surgery in 2001. Working in accordance with the principles of piezoelectricity, it makes an incision in the bone tissue by means of ultrasonic vibrations. Recently, devices have been successfully used in rhinoplasty.
PIEZOELECTRIC DEVICE
Piezo surgery devices use ultrasonic vibration, which is expanded and constricted by the pressure applied. This device is providing a cutting effect on mineralized, hard tissues as a bone, and does not damage the soft tissues such as mucosa, vessel and nerve during the surgery. This situation is the most important feature of this technology.
The device consists of the main unit, the handpiece and the active insert. Active inserts that function in piezoelectric devices show upwards and downwards 40 – 200 and 20 – 60 microns in forward – backward direction. In order to produce the cutting effect, it is enough to apply much less pressure than the mechanical tools used for the same purpose.
