Laser-assisted endoscopic septal surgery (LESS)
Laser-assisted endoscopic septal surgery allows a surgeon to use a probe with a tiny camera (endoscope) to see deviations or bends of the large cartilage dividing the nose into nostrils, which is a very common cause of nasal obstruction or blockage of the airflow through the nostrils.
This allows a surgeon to see images of the body's internal structures through very small incisions or through a natural body opening like the nostril. The surgeon uses the laser to perform the actual surgery. Since the incisions are shorter with endoscopy and made with the laser, there is a decreased risk of losing feeling at the tip of the nose.
