Laser and radio frequency surgery

The use of the CO2 Laser in some cases is irreplaceable in our specialty. In the atresia of the nasal funnels, many times in the surgery of the larynx (papillomas, tumors, laryngitis, etc.), in the surgery of otosclerosis (anabolotomy), but also sometimes in the surgery of the oropharynx.

But it is certainly, today, much less used since in many cases it was replaced in the last 8-10 years by radio frequencies. This is because they are much "kinder" to the tissues which they do not burn like the Laser. So in the surgery of the nasal cavities, in operations on the mouth (for snoring, apneas, removal of tonsils or tumors) and the tongue, in operations on the skin they have completely undercut the Laser.

The operations became more painless, usually no hospitalization is needed and the postoperative course is much faster.



Robotic surgery

Robotic surgery is a great innovation in surgery for both the patient and the doctor. It is for a minimally invasive method (minimally invasive surgery) that concerns almost all branches of medicine.

Robotic surgery in otorhinolaryngology is the most modern way of accessing the oral cavity. The doctor uses small instruments and a camera in the oral cavity and pharynx - larynx, which he directs through a console.

The micro-tools used inside the oral cavity have a great ability to rotate and, therefore, quickly deal with the problems. The surgeon handles the operation through the control console, without intervening himself. The camera offers image magnification of the area of ​​interest and 3D imaging.
