Several types of benign and malignant tumors may occur in the nose and sinus cavities. Traditionally, these tumors have been removed with a variety of facial or skull incisions. Advances in endoscopic minimally invasive techniques allow the surgeons to remove these tumors completely, safely without any facial incisions. The surgeon removes these tumors through the patient's nose, a natural opening, thus avoiding facial or skull incisions. Patient's typically experience fewer complications, decreased pain, and leave the hospital sooner with the use of these techniques.
