Patients with chin retrusion frequently present with increased chin hypertonia. Monotherapy with HA falls short in addressing the multifaceted cosmetic concerns associated with chin retrusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>This study aimed to investigate the clinical efficacy and safety of the combination therapy involving botulinum toxin (BTX) and HA in the treatment of chin retrusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We enrolled patients with moderate to severe chin retrusion for 9 months of follow-up after they received either combined treatment with BTX plus HA or monotreatment with HA. We also calculated the surface-volume coefficient with 3-dimensional digital scanning technique, and evaluated outcomes based on the Allergan Chin Retrusion Scale (ACRS), the Global Aesthetic Improvement Scale (GAIS), and treatment-related adverse events (TRAEs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 50 patients were recruited and randomized to the treatment group (BTX plus HA) or control group (HA alone) in a 1:1 ratio. Patients in the treatment group exhibited significantly higher surface-volume coefficients during the first 6 months (P &amp;lt; .05). ACRS scores and responder rates in the 2 groups remained similar throughout the follow-up (P &amp;gt; .05). Within the initial 3 months, the GAIS responder rate in the treatment group was significantly higher than that in the control group (P &amp;lt; .05). Mild TRAEs were observed in both groups, and subsided within 7 days. There was no increase in adverse effects with the combined treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In comparison to monotherapy, the combined treatment not only improved the surface-volume coefficient of hyaluronic acid but also achieved similar ACRS scores with less HA volume.
