Nonsurgical Rhinoplasty Using Hyaluronic Acid Dermal Filler in Asian Patients

The appearance of an individual's nose plays a pivotal role in facial aesthetics. A nose that is proportionate to a person's face enhances facial balance and appearance. Traditional surgical rhinoplasty has been a common solution for addressing the flatter nasal dorsum and broader alar base and improving nasal prominence for individuals of Asian descent. Recently, nonsurgical rhinoplasty (NSR) has gained popularity because it offers a minimally invasive alternative to surgical rhinoplasty with reduced downtime. This review examines the application of hyaluronic acid (HA) fillers in NSR, particularly for Asian patients, highlighting techniques and considerations tailored to the unique nasal anatomy of this population. We discuss the historical context of filler use, the specific nasal characteristics of East Asian individuals, and the clinical techniques for successful filler application. Additionally, we detail five primary subcategories of HA filler-based NSR: nasal dorsum augmentation, glabella correction, nasal tip correction, columella correction, and nasolabial angle correction that emphasize the importance of using biphasic HA fillers with large particle sizes to mitigate risks such as swelling and lateral expansion. We identify the anatomical and procedural nuances critical for achieving optimal results. We suggest that future research in this area should focus on refining injection techniques and exploring new filler formulations to enhance the safety and efficacy of NSR in Asian populations.
