ABSTRACT
PURPOSE: The study aimed to evaluate and compare the efficacy and safety of treating atrophied labia majora with hyaluronic acid (HA) and calcium hydroxyapatite (CaHA). METHODS: Ten participants complaining of sagging or loss of volume in the labia majora were evaluated and randomly assigned to two groups-treated with CaHA or AH. Photographic documentation was taken and appreciated by the participants and by blind observers. RESULTS: The study showed an improvement in labia majora regarding volumization and flaccidity that was more significant after 90 days of treatment in both treatments. Besides flaccidity, volume replacement resulted in better balance and proportion between the labia majora and labia minora. The evaluators, independent and blind, judged that in 80% of the cases of the HA group and in 50% of cases of the CaHA group, there was an excellent improvement. CONCLUSION: CaHA and HA are both effective and safe for treating the intimate region, and this study cannot prove the superiority of one over the other. An appropriate assessment involving the analysis of sagging and/or volume loss and the creation of a sequential treatment protocol, involving CaHA and HA, seems to be the best solution. LEVEL OF EVIDENCE I: Evidence obtained from at least one properly designed randomized controlled trial. This journal requires that authors assign a level of evidence to each article.
