Laser Surgery

In the MEDICAL VOICE CENTER, laser surgery on the larynx has been performed for many years with a photoangiolytic KTP laser (wavelength KTP at 532nm). Since 2016, Prof. Hess, as one of the pioneers in laryngeal surgery, has been using the new generation, the so-called ‘blue’ laser (wavelength at 445nm). Since then he has performed more than 1,000 operations with the ‘blue’ laser.

This procedure is not only applicable in recurrent respiratory papilloma (RRP), but also in many other lesions. Within a few minutes the surgery is done – and in some cases never needs a second treatment. In some patients the operation in general anesthesia can be avoided with this therapeutic strategy.

This pain free and very well tolerated surgery method with the KTP laser is frequently used in the USA and keeps patients from being operated in general anesthesia.

KTP Laser

The KTP Laser is used in the USA since approx. 20 years. It is a laser that has a photoangiolytic effect and therefore works different than a CO2 laser. With KTP, vessels in deeper layers can be coagulated without destroying the covering epithelium.
This painless and well-tolerated laser surgery has been increasingly used in the USA in recent years, replacing surgery under general anesthesia in many cases.

Because of our extensive experience in laser surgery we are often asked to share our knowledge which is accordingly and frequently offered in workshops and meetings for ENT colleagues.

Blue Laser

The blue laser (wavelength 445nm) is used routinely since 2016 – our institution being the first one worldwide to introduce this laser and show it’s suitability for laryngeal tissue lesions.

The so called blue laser is a new and unique laser for laryngology. This 445nm laser broadens the spectrum of of applications and indications for surgeons as it combines photoangiolytic and cutting properties.
The standard cutting laser, the CO2 laser, is used since decades in all ENT clinics. Photoangiolytic lasers are relatively new (PDL, KTP, Argon) and are not widespread in use in Germany. In essence and to our opinion, the blue laser may be seen as the newest development of a combined laser technology.
