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

Area of Science:

• Plastic Surgery
• Facial Aesthetic Surgery

Background:

• Dorsal preservation rhinoplasty (DPR) is gaining popularity, with claims of superior results compared to open structural rhinoplasty (OSR).
• Limited comparative outcome data exists between DPR and OSR.
• This study investigates expert ability to differentiate between DPR and OSR based on aesthetic outcomes.

Purpose of the Study:

• To determine if experienced rhinoplasty surgeons can identify aesthetic differences between dorsal preservation rhinoplasty and open structural rhinoplasty.
• To evaluate the aesthetic outcomes of DPR and OSR at short-term (2.5 months) and medium-term (1 year) follow-up.

Main Methods:

• A survey of OSR and DPR cases was distributed to members of the Rhinoplasty Society and Dallas Rhinoplasty instructors.
• Results were analyzed based on surgeon expertise and correlated with rhinoplasty experience.
• Statistical analysis included Chi-square, Fischer's exact test, Student's t-test, and Pearson's correlation coefficient.

Main Results:

• Fifty-one surgeons responded, with an average of nearly 10 years of experience.
• The average correct identification rate for OSR vs. DPR was 58% at 2.5 months and 61% at 1 year.
• No correlation was found between survey score and surgeon experience, comfort level, or utilization of preservation techniques.

Conclusions:

• No discernible aesthetic differences were observed between OSR and DPR at one year post-surgery.
• Both OSR and DPR techniques are considered effective and can be combined for optimal rhinoplasty results.
