Laser Assisted Ear Surgery in Hyderabad

What is Laser?

LASER stands for Light Amplification by Stimulated Emission of Radiation. It is produced by electrically stimulating a particular material, which could be a solid, a liquid, or a gas. Light from a laser is tuned to specific wavelengths, which allow it to be focused into powerful beams.

Surgeons employ various laser wavelengths and laser delivery systems to cut, coagulate, vaporize, and remove tissue. With the use of lasers, surgeon can accomplish tasks such as reducing blood loss, decreasing postoperative patient discomfort, less pain & swelling, decreasing the chances of infection to the wound, less scarring than traditional surgery and achieving better outcomes in wound healing.

In medicine, laser is used, in almost all surgical procedures, to allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue. Laser surgeries are often referred to as “bloodless surgeries” as the heat generated by the laser seals off blood vessels and nerves, reducing bleeding, pain, swelling. It also keeps the surgical site free of germs and reduces the risk of infection. Laser procedures often take less time (and cost less money). The recovery period is also shorter.

Lasers provide a precise and bloodless method of operating on the delicate structures of the ear. They are especially useful in stapedectomies, otosclerosis and in removing inflamed tissue e.g. cholesteatoma. The safety of lasers in ear surgery is confirmed by experienced ear surgeons who have carried out 1000+ major ear surgeries.

There are a number of different types of laser. Each has a different use and colour.

Types of lasers:


The three types of lasers most often used in medical treatment are:

  • Carbon dioxide CO2 laser: Primarily a surgical tool, this device converts light energy to heat, which is strong enough to minimize bleeding while cutting through or vaporizing tissue.
  • Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser: This is capable of penetrating tissue more deeply than other lasers. The Nd:YAG laser enables blood to clot quickly, allowing surgeons to see and touch body parts that could otherwise be reached only through open (invasive) surgery.
  • Argon laser: This laser uses light-sensitive dyes to shrink or dissolve tumors. It facilitates limited penetration for E.N.T. surgery and superficial skin disorders.

Lasers have been applied to several types of otorhinolaryngology for a wide variety of lesions. Lesions situated in relatively inaccessible areas such as the nasopharynx, subglottic area of the larynx, and tracheobronchial tree may be excised, obliterated, or corrected in any age group. Lasers are very commonly used for:

  • Complete cholesteatoma removal
  • Hyperplastic infected mucosa
  • Chronic ear surgery
  • Stapedotomy and acoustic tumor vaporization
