INTRODUCTION

Laser is now universally accepted as the most advanced technological tool in various specialities of surgery. However the properties of all lasers are not alike and surgeries in the ENT field have advanced significantly with the introduction of Diode Laser.

Diode Laser offers the most bloodless surgery available today. This laser is especially suited for ENT works and finds application in various aspects of surgery in the ear, nose, larynx, neck etc. With introduction of Diode Laser, there has been a significant improvement in the quality of ENT surgery.

The commonly used lasers in ENT till date were CO2 (carbondioxide), argon laser and Nd: YAG laser. The diode laser, 980 nm wavelength which was invented and introduced to the field of ENT surgery recently, combines the beneficial effects of all these lasers into one. The tissue cutting effect is comparable to that of CO2 laser, its coagulation effects are comparable to that of argon laser, and it results in a slightly higher degree of absorption by tissue than does the ND: YAG laser.

 This a lightweight, portable 980nm wavelength Diode laser with a fiber optic delivery system is being used widely the field of otolaryngology, as it is more affordable.

ADVANTAGES:

• Low cost
• Bloodless treatment
• High precision ablation
• Fast and gentle outpatient treatments
• Mini-invasive surgery through flexible fiber optics
• Easy operation, can be introduced by endoscope
• Enhanced healing
• Less postoperative trouble

APPLICATIONS:

1. It can be used in contact mode, in which the tip of the fiber is placed directly on the surface of the tissue. This mode is effective for both photocoagulation and vaporization of tissue, depending on the power density. At the low- or mid-power range, coagulation occurs; at a higher level, vaporization occurs.

2. The laser can be used in near-contact mode, in which the tip of the fiber remains several millimeters apart from the tissue. This mode is largely used for tissue photo coagulation .
