Nonsurgical Reshaping of the Lower Jaw With Hyaluronic Acid Fillers: A Retrospective Case Series

INTRODUCTION: Nonsurgical aesthetic treatments of the lower face are increasing in demand. In particular, they aim to restore facial youth following the changes due to progressive resorption of facial skeleton and atrophy of facial fat compartments which give the perception of a descent face. OBJECTIVES: The aim of this research is to describe the nonsurgical reshaping of the aged lower jaw by means of hyaluronic acid fillers. METHODS: A retrospective analysis of data from adult female patients undergoing treatment with hyaluronic acid injections in the lower third of the face was performed. Injection techniques, relevant anatomy of the anatomical area and rheological properties of the fillers to be used are highlighted. RESULTS: Thirty-six consecutive patients were enrolled (100% female; mean age: 45.7 years). A minimum of 4 up to 7 vials of hyaluronic acid filler was injected to achieve the desired results. The visual analogue scale was used to assess patient satisfaction. Thirty-two patients (88.8%) rated their appearance post-treatment with a satisfaction score ranging between 85% and 100%. A total absence of ecchymosis and/or swelling in the early postoperative days has been highlighted. There were no cases of infection, paresthesia, hematoma or necrosis. CONCLUSIONS: For those patients not willing to undergo surgery, the jawline remodelling with hyaluronic acid fillers seems to be a viable option for ameliorating the definition of the lower third of the face. Nonetheless, it is mandatory to perform multilayer injections using fillers with different rheological properties.
