Open Structural Versus Dorsal Preservation Rhinoplasty: A Comparative Survey Study of Aesthetic Outcomes.

[INTRODUCTION] Dorsal preservation rhinoplasty (DPR) is increasingly popular, with some suggesting superior outcomes over open structural rhinoplasty (OSR). To date, there has been little investigation into comparative outcomes between the techniques. This study aims to ascertain whether experts in the field can differentiate between the techniques in aesthetic outcomes.

[METHODS] A survey was created that consisted of OSR and DPR cases with an average 2.5 month and 1 year follow-up. The survey was distributed to the Rhinoplasty Society and Dallas Rhinoplasty instructors. Results were correlated to expertise in rhinoplasty. Univariate analysis was performed using Chi-square or Fischer's exact test for categorical variables and Student's t-test for continuous variables. Pearson's correlation coefficient was used to assess the relationship between study variables. Statistical significance was defined as p < 0.05.

[RESULTS] Fifty-one plastic surgeons responded (24.2 % response rate). Participants averaged almost 10 years of experience, with an average 58 rhinoplasties performed annually. 59% used open techniques and 39% used both open and closed. 54.5% utilized preservation techniques. The average correct survey score was 58% at 2.5 months and 61% at 1 year. There was no positive correlation between survey score and rhinoplasties performed, experience in years, comfort level or utilization of preservation rhinoplasty techniques.

[CONCLUSIONS] The study demonstrates no discernable differences in aesthetic results when using OSR and DPR techniques at 1 year after surgery. Ultimately, OSR and DPR techniques should both be considered and potentially combined, when performing rhinoplasty.
