Application of Paranasal Augmentation Rhinoplasty in Asians With Midfacial Concavity

Abstract

Background For Asian rhinoplasty patients with midfacial concavity, the conventional method is to solve the problem by using structural rhinoplasty to increase the nasal height and length. However, the results are not satisfying, and many complications are caused. Paranasal augmentation as an adjunct to rhinoplasty can improve surgical results and increase satisfaction. However, there are limited studies focusing on the details and evaluation of this technique. Objectives To investigate a minimally invasive method to correct midfacial concavity simultaneously with rhinoplasty, as well as improve satisfaction and reduce complications. Materials and Methods Between January 2010 and December 2019, we reviewed all rhinoplasty patient records from patients who had midfacial concavity and underwent simultaneous paranasal augmentation with our technique. The patient demographics, surgical characteristics, and outcomes were reviewed retrospectively. Satisfaction was evaluated by an independent medical staff who reviewed the preoperative and postoperative photos. Results Sixty-seven patients were included in the study. The mean age of the patients was 28.7 ± 8.0 years, and the median follow-up time was 26 months (range, 2–60 months). Overall satisfaction was high (90%). Eight (12%) patients had complications, including 5 (7.4%) cases of implant displacement and 3 (4.4%) cases of infection. All patients healed uneventfully after revision surgery. Conclusions Paranasal augmentation can improve the outcome and increase satisfaction in Asian rhinoplasty patients who have midfacial concavity. Preoperative patient evaluation, surgery planning, and surgery details are crucial to ensure a favorable result. The expanded polytetrafluoroethylene implant has advantages over other materials and therefore is recommended in paranasal augmentation surgery.
