New approaches in laser surgery of paranasal sinuses

In the field of otorhinolaryngology lasers, especially the 002 laser, sometimes the NdYag Laser, have been used for many years. However their application has been limited to easily accessible region e. g. diseases in the oral cavity, the oro- and hypoharxynx and the larynx. The upper air ways, especially the nose, the paranasal sinuses and the nasopharynx are narrow and hidden regions, which have proved a challenge to the optical and laser engineers and physicians.
