State of the Evidence for Preservation Rhinoplasty: A Systematic Review.

Preservation rhinoplasty encompasses a number of techniques that minimize disruption of the native cartilaginous and soft tissue nasal architecture. These techniques have gained popularity resulting in an increase in publications relevant to preservation rhinoplasty. However, many studies that present patient outcomes are of low-level evidence and do not incorporate validated patient-reported outcome measures. While these studies do consistently report positive outcomes, there are few high-level comparative studies that support the theoretical benefits of preservation relative to structural rhinoplasty. As contemporary preservation rhinoplasty techniques will continue to evolve and become incorporated into clinical practice, there will be the need for parallel emphasis on robust clinical studies to delineate the value of these methods.
