Abstract
The KTP/532 laser dwells in the visible segment of the electromagnetic spectrum and does not need an aiming beam. This wavelength is preferentially absorbed by haemoglobin and therefore, the laser energy results in better coagulation. The laser beam is delivered through a quartz fibre in a hand held delivery with an adjoining suction channel for evacuation of smoke. The laser beam exists as a divergent beam with maximum energy at its exit and minimal as the beam diverges away from the tissue. Taking advantage of this characteristics, the surgeon changes the distance between the tissue and the fibre achieving cutting, vaporization and coagulation effect on the tissue. The tissue penetration of this wavelength is slightly more than CO2 and considerably less than Nd.Yag laser. This wavelength of KTP is widely used in rhinology to deal with various pathologies. It has a specific application in the field of Endoscopic Sinus Surgery especially revision cases.
