Advanced strategies for mental augmentation with hyaluronic acid – a case series using the profile approach

Objective: Hyaluronic acid (HA), due to its high reversibility, low incidence of adverse events, and patient acceptance, is a viable option for correcting mild to severe retrognathia. This work aims to systematize and suggest non-surgical options that impact facial profile through the ProT technique. Methods: Depending on the level of retrognathia, HA injections are administered in varying depths, with severe cases also requiring neuromodulator treatment. Proper injection techniques and materials are recommended to enhance treatment effectiveness and durability. Results: The case series showed significant improvements in mental region projection and definition, with 40%, 50%, and 70% enhancements for cases 1, 2, and 3, respectively. Case 2 also had a 15% increase in the distance from the oral commissure to the mandibular base and a 3.25 cc volumetric gain in the mental region. These results indicate substantial improvements in facial aesthetics following the intervention. Limitations: We can consider individual anatomical variations, tissue response, and the clinician´s ability as limiting factors for technique reproducibility. Conclusion: The Profile Technique (ProT) utilizes HA gels and, optionally, neuromodulators tailored to each patient's facial profile to effectively correct retrognathia. This approach results in significant improvements in facial aesthetics while ensuring safety, making ProT a minimally invasive and effective method for enhancing facial harmony.
