Microinjection Technique: A Novel and Comprehensive Approach for Nose Reshaping with Hyaluronic Acid Fillers.

Introduction: Nose reshaping with hyaluronic acid (HA) fillers, also known as medical rhinoplasty, is an increasingly popular, minimally invasive aesthetic procedure. As the demand for nasal reshaping continues to rise, it is essential to develop safe and efficient injection techniques and assess satisfaction to ensure optimal outcomes and patient-centered care. Objective: This study aims to evaluate patient and physician satisfaction with hyaluronic acid filler applications using microinjection technique for nasal reshaping. Methods: The study included healthy adult patients who underwent medical rhinoplasty with the same HA filler using the microinjection technique. Patient satisfaction levels were evaluated at one and six months after the last injection using the Global Patient Satisfaction Scale (GPSS). Additionally, an independent dermatologist conducted a clinical evaluation for each patient by comparing before and after clinical pictures, using the Aesthetic Improvement Scale (AIS). Any side effects were recorded during each session and follow-up period for six months. Results: A total of 40 patients (37 women and 3 men) participated in the study. The most frequently targeted anatomical areas for filler injections were the nasal tip (100%), columella (100%), nasal prominence (100%), nasal dorsum (85%), and nasal root (82.5%). Injections distal to the nasolabial fold (NFL) were performed in 2.5 percent of patients. Patients expressed high satisfaction with the results at both one and six months after the procedure (mean GPSS, respectively; 4.65 and 4.47). Similarly, clinicians reported satisfaction with outcomes at the same time points (mean AIS, respectively; 1.7 and 1.4). Apart from mild pain during the procedure and transient erythema afterward, no side effects were recorded. Conclusion: Medical rhinoplasty with HA fillers using the microinjection technique is an effective and reliable procedure. This technique provides safe and aesthetically pleasing results from both patient and dermatologist perspectives, making it a favorable option for nasal reshaping with HA dermal fillers.
