LASER Technology in ENT Surgery


Ever wondered what LASER stands for? It’s ‘light amplification by stimulated emission of radiation.’ The beauty of a laser lies in its uniform energy waves, making it an exceptional cutting tool in medical procedures. Unlike conventional cutting instruments, lasers not only slice but also cauterize tissue simultaneously, preventing bleeding.

In the realm of ENT surgery, several laser types come into play:

  • Diode Laser, generating intense heat with potential scar tissue formation.
  • KTP Laser, selectively targeting blood vessels while preserving healthy tissue.
  • CO2 Laser, an incredibly precise cutting tool, often utilized with an operating microscope.

Yet, alternatives exist. Options like Cautery and Diathermy (relying on electric current for heat), Coblation (using low-heat radiofrequency and saline to separate tissue), or a Microdebrider (a versatile instrument with cutting, saline irrigation, and suction channels) offer the ENTsurgeon flexibility in approach.Each method has its indications, and it’s wise to consult your ENT specialist to determine the best approach for your specific procedure, rather than insisting on a particular method.
