Overview of Dorsal Preservation Rhinoplasty.

Renewed interest in dorsal preservation rhinoplasty (DPR) stems from theoretic esthetic and functional advantages over conventional hump resection. DPR fundamentally consists of en bloc dorsal lowering via a combined septal resection and mobilization of the bony pyramid. Several technical modifications exist, allowing for the expansion of DPR indications. Although studies suggest success with these techniques, comparative data to conventional hump resection are limited. Challenges and stigmata of DPR include a radix step-off, hump recurrence, supratip saddling, and widening of the midvault. The fusion of structural techniques with preservation ideology will facilitate the incorporation of DPR into clinical practice.
