Background: Absorbable wedge-shaped polydioxanone (PDO) sutures are currently available for facial rejuvenation, and they are extremely popular in the aesthetic clinics in Korea. Other than face lifting, threads also can be used for nonsurgical rhinoplasty. The Asian nose is typified by a flat nasal bridge, indistinct nasal dorsum, underprojected and broad nasal tip, and a short columella. In the past, Asian rhinoplasty mainly focused on dorsal augmentation. At present, augmentation of the nasal tip is very popular and is considered an important aspect of achieving a natural and balanced nose.
Objective: To describe a novel technique with PDO threads in nonsurgical rhinoplasty. In addition, the authors aimed to assess the overall safety and efficacy of nonsurgical rhinoplasty combining both fillers and threads.
Methods: A retrospective analysis was performed on Korean patients who received rhinoplasty with PDO threads and fillers. All participants underwent a single treatment session. The results were assessed objectively by 2 independent dermatologists using serial photography and subjectively based on the patients' satisfaction scores at 6-month follow-up.
Results: A total of 31 patients were evaluated, and 93.5% considered the results satisfactory. Consensus ratings at the 6-month follow-up were largely categorized as very much improved (38.7%), much improved (35.5%), and improved (25.8%). An average increase of 6.3° (percentage increase by 7.6) in the nasolabial angle (p < .05) was measured at follow-up. The incidence of the complications was low, and the ones reported were minor.
Conclusion: Nonsurgical rhinoplasty combining PDO threads and fillers can be safe and effective, maintaining good results at 6 months after the procedure. Threads are especially useful for lifting-up the nasal tip, contributing to a more harmonious and pleasing nasal appearance by modifying the columella-labial angle.
