NOVA Spare Roof Technique and the Sail Maneuver-Vectorial Rhinoplasty Without Lateral Keystone Area Disarticulation

The authors propose a novel variation of the Spare Roof Technique for Preservation Rhinoplasty-"NOVA Spare Roof Technique." This modification involves a newly developed maneuver, the Sail Maneuver, which is a simple rhinoplasty technique for treating dorsal humps without lateral keystone area disarticulation. The authors find that this rhinoplasty strategy can be a precise surgery for a smooth and natural dorsum with a natural transition on the dorsal keystone area and, simultaneously, can improve the dorsal aesthetic lines (DALs). This approach is based on the new "dorsal vectorial concept" in rhinoplasty. A patient with a dorsal hump on a profile view can have a significant impact on the vector of the DALs. This rhinoplasty approach addresses that problem with a mathematical rationale.
