Abstract:
Endonasal rhinoplasty is a minimally invasive approach in which esthetic and functional improvements are made solely through intranasal, without transcolumellar, incisions and with limited soft tissue and skeletal disruption. In addition to intentionally limiting surgical dissection, the rhinoplasty surgeon must preoperatively recognize and surgically correct 4 common anatomic variants which predictably create all 3 patterns of secondary deformity. In combination, respecting these principles gives the surgeon greater predictability in achieving esthetic and functional improvements, and the ability to limit the adverse effects of skin contractility and postoperative scar contracture, thus reducing the risk of secondary deformity, patient dissatisfaction, and reoperation.
