Spreader septal extension graft can extend from middle nasal vault into the tip-lobule complex to augment the anterior septal angle. But spreader graft can not be used to augment all three angles of caudal septum: anterior, middle and posterior septal angle.
How is Dr. Jung's experience with "caudal septal extension graft" to augment all three angles of caudal septum: anterior for increasing tip projection, middle and posterior for increasing nasolabial angle and correcting a retracted columella?
