Objectives: To determine the safety and efficacy of using Polydioxanone (PDO) threads in non-surgical rhinoplasty for Asian patients. Introduction: The nose occupies the center of the face; the size, shape and angles of the nose dictates the profile and balance of the face, in relationship with the other facial features. Asians have lower and flatter nasal dorsum, a rounded or bulbous tip, weak lower lateral cartilages, rounded nostrils, and a short columella. Non-surgical rhinoplasty using threads, is one of the most common and popular procedures in Asia. The goal of thread rhinoplasty is to increase the height of the nasal dorsum, and lengthen the columella to improve the nasal tip angle, and nasolabial angle. Materials / method: This study examined 10 Southeast Asian patients, aged 18 years and above, with no previous procedures done on the nose. Digital photographs were taken before and immediately after the procedure. Using these photos, the following were measured: nasofrontal angle, nasolabial angle, nasal dorsum length, nasal tip projection and width of nasal bridge. Results: The average decrease in nasofrontal angle is 14 degrees, ranging 10 to 20 degrees. The average increase of nasolabial angle is 12 degrees, ranging from 5-26 degrees. The average decrease in nasal dorsum length is 2.20cm, ranging from 0-4cm. The average increase in nasal tip projection or columellar lengthening is 2.8cm, ranging from 2-4cm. The average decrease in the width of nasal bridge is 2.6cm, ranging from 2-4cm. There were reports of swelling and bruising in which lasted for an average of 5 days. There were no infection, migration, and rejection reported. Conclusion: It is safe and effective to use polydioxanone threads as a non-surgical option in aesthetically improving Asian noses.
