Abstract

Background: A more pleasing nasal tip appearance is becoming the most frequent reason for nonsurgical aesthetic rhinoplasty procedures. Objective: To present the "Diamond Injection Technique," an innovative 4-point hyaluronic acid (HA) filler injection procedure for nasal tip refinement and to assess its aesthetic outcomes and efficacy. Methods: Data were collected from a prospective single-center cohort of patients undergoing nonsurgical rhinoplasty with injectable fillers. Anthropometric measurements, the 5-point Global Aesthetic Improvement Scale (GAIS), and a patient-reported questionnaire were used to evaluate the aesthetic outcomes and treatment efficacy before treatment and 6 months later. Results: The study included 107 patients; 82 were women. The median age was 35 (18-47) years. The mean volume of HA filler injected was 0.12 mL (range: 0.05-0.2). At 6 months, the GAIS-calculated outcome was excellent in 90.65% of patients, with a high degree of patient satisfaction and objectively pleasant changes in anthropometric measurements. Conclusions: The "Diamond Injection Technique" proves to be a safe, comprehensive, and effective procedure for refining the nasal tip to a pleasing diamond shape, satisfying a high percentage of patients.
