Injectable soft tissue fillers offer a less invasive alternative to genioplasty. This study aimed to compare the esthetic outcomes of chin augmentation using the abovementioned two methods.</span></span> <span style="line-height:95%"><b><span style="line-height:95%"><span style="color:#2e74b5">Materials and Methods: </span></span></b><span style="line-height:95%">This comparative interventional study enrolled 36 patients with mild to moderate microgenia presenting to the Department of Oral Surgery, Faculty of Dentistry, Islamic Azad University of Medical Sciences. They were candidates for chin contour correction through sliding genioplasty or hyaluronic acid filler injection (n=18 in each group). Photographs were obtained before and 3 months after genioplasty surgery and 1 month after filler injection. Subsequently, the images were evaluated by 10 oral and maxillofacial surgeons, 10 orthodontists, and 20 laypersons, using a visual analog scale (VAS) to appraise facial attractiveness after treatment. Comparisons were made by independent t-test (alpha=0.05).</span>&nbsp;</span> <span style="line-height:95%"><b><span style="line-height:95%"><span style="color:#2e74b5">Results: </span></span></b><span style="line-height:95%">Orthodontists and oral and maxillofacial surgeons found no significant difference between the two methods in terms of facial aesthetics post-procedure (P>0.05). However, laypersons gave higher esthetic scores to genioplasty (P=0.02).<span style="font-family:"Verdana",sans-serif"></span></span></span> <span style="line-height:95%"><b><span style="line-height:95%"><span style="color:#2e74b5">Conclusion:</span></span></b> <span style="line-height:95%">Based on the present results, orthodontists and oral and maxillofacial surgeons did not identify any significant difference in facial attractiveness between sliding genioplasty and hyaluronic acid filler injection. However, laypersons tended to rate genioplasty more favorably. </span>&nbsp;</span></span></span> &nbsp;</pre> Genioplasty, Dermal Fillers, Chin, Cosmetic Techniques, Hyaluronic Acid 86 93 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1314-1&slc_lang=en&sid=1 Behnaz poorian BEHNAZPOORIANG@GMAIL.COM 100319475328460012331 100319475328460012331 No Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran.
