ABSTRACT
The external female genitalia undergo significant anatomical and physiological changes due to intrinsic aging, menopause, massive weight loss, and multiparity. These factors often lead to a progressive loss of subcutaneous adipose tissue and dermal collagen in the labia majora, a condition clinically referred to as “vulvar hypotrophy.” As the labia majora lose their protective cushioning function, the labia minora become more prominent and exposed, which can result in both aesthetic dissatisfaction and functional issues such as dryness, irritation, and dyspareunia. This chapter provides a comprehensive clinical guide on the non-surgical augmentation of the labia majora using hyaluronic acid (HA) fillers, which have emerged as the gold standard in aesthetic gynecology due to their predictable results, min-imal downtime, and unique reversibility.
We conduct a critical comparison between HA fillers, calcium hydroxylapatite (CaHA), and novel hybrid fillers (HA + CaHA). While CaHA and hybrid fillers offer the advantage of neocollagenesis and potentially longer-lasting volume restoration, they lack a specific dissolving agent, posing a higher risk in the event of vascular compromise. Consequently, this chapter emphasizes the safety profile of HA, particularly its reversibility with hyaluronidase, making it the preferred choice for a “Safe Reversal Protocol.”
Furthermore, detailed attention is given to the anatomical considerations and precise injection tech-niques required to achieve natural and safe results. Based on recent expert consensus, we highlight the importance of depositing the filler into the deep subcutaneous fatty tissue or immediately superior to Colles’ fascia to avoid complications such as superficial nodules, granulomas, and the Tyndall effect. The use of blunt-tipped cannulas (21G or 22G) via a retrograde linear or fanning technique is strongly recommended to minimize the risk of intravascular injection.
Finally, the chapter outlines a robust protocol for complication management, specifically detailing the “High Dose Pulsed Hyaluronidase” protocol for the immediate treatment of vascular occlusion. Clinical outcomes reviewed in this section demonstrate that labia majora augmentation is not merely a cosmetic enhancement; it significantly improves women’s quality of life, increasing Genital Self-Im-age Scale (FGSIS) scores and reinforcing sexual self-confidence and couple compatibility.
