Non-surgical Rhinoplasty (NSR): A Systematic Review of Its Techniques, Outcomes, and Patient Satisfaction

Surgical rhinoplasty (SR), commonly known as nose job, is a widely practiced cosmetic surgery globally, aimed at addressing diverse aesthetic and functional concerns related to the nose. In recent years, non-surgical rhinoplasty (NSR) has gained popularity due to advanced techniques involving hyaluronic acid (HA) dermal fillers, offering advantages such as affordability, reduced side effects, and faster results. However, concerns persist about the suitability of dermal fillers for nasal anatomy and potential complications, prompting this comprehensive review. This study systematically evaluated the techniques, fillers, safety, and patient satisfaction associated with NSR, with the intent of providing valuable insights for clinicians and patients considering NSR or SR for improved aesthetic outcomes. The literature search, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, yielded 16 relevant studies from an initial pool of 1002 articles. These studies covered various aspects of NSR, including techniques, complications, limitations, and positive results. In conclusion, NSR appears to be a quick and safe option for addressing minor nose shape issues, particularly through the use of HA fillers, but further discussion and standardization are necessary to address risks and limitations. A randomized controlled trial (RCT) using photographic evidence could significantly propel the progress of this evolving treatment. RCTs offer an optimal method to assess NSR's adverse effects and overall outcomes by allowing controlled comparisons between treatment and control groups. This approach minimizes biases and generates reliable statistical data, which is critical for evaluating safety, efficacy, and potential risks, thereby guiding informed clinical decisions.
