Surgical Technique
The surgical technique is practiced by small divisions, using the assistance of an optical system that allows the team physician to view the surgical field within the patient and act on it. It calls these minimally invasive techniques, as they avoid the deep cuts required by scalpel or conventional open surgery and possible, therefore, a post-operative period much faster and comfortable.
