  • An essential step in septal surgery is the correct identification of the subperichondrial plane. Access to this plane can be improved by hydrodissection under enhanced vision. Hydrodissection consists of pressure insufflation of fluid into an anatomical space with a consequent increase in the hydrostatic pressure that separates the tissue planes. In septal surgery, the subperichondrial plane is hydrodissected by infiltration of 2 ml of xylocaine with adrenaline. This creates a bloodless and wide surgical field that facilitates surgery. With the use of a surgical microscope equipped with a teaching arm, it is possible to teach nasal anatomy and septal surgery to trainees.
