Objectives: 1. Discuss the range of chin deformities 2. Present options from fillers to fat to surgical alterations 3. Remind practicioners that even when using fillers to the chin, the patient should be questioned about signs and symptoms of sleep apnea Introduction: Aesthetic alterations of the chin are extremely rewarding procedures. Chin deformities may be isolated or more widespread and associated with class 2 and 3 malocclusions. In addition, even aesthetic chin concerns may be associated with more serious issues such as sleep apnea. Consideration of the full gamut of chin deformities as well as their treatment may be helpful when considering non-surgical options. Materials / method: Over the past 5 years the senior author has treated 280 patients with aesthetic chin concerns. Of these patients, 225 underwent filler injections with either calcium hydroxyapatite or an HA; 55 patients underwent surgical treatment with fat (n= 20); chin implants (n=9) and osseous genioplasty (n=26). In patients undergoing genioplasty, 10 had mandibular advancement with or without maxillary repositioning. Results: Satisfactory results occurred in the vast majority of patients. Additional filler injection was performed in less than 5% of the 225 patients. One patient had a small amount of calcium hydroxyapatite removed. Of the osseous genioplasty patients, one patient required revision and there were 2 minor infections, which resolved with needle aspiration and oral antibiotics. None of the patients having chin implants had complications and no patient having fat grafting requested more, although, 2 patients would have benefitted. Conclusion: Understanding the wide variety of aesthetic chin disorders is important in selecting the proper treatment.
