Vertical incision intraoral silicone chin augmentation

Solid silicone augmentation mentoplasty is a common procedure with consistent aesthetic results in properly selected patients. While many plastic surgeons employ the external approach, the intraoral method affords excellent aesthetic outcomes while avoiding an external scar. This is the largest series in the literature describing the midline intraoral incision approach with minimal disruption of soft tissues.

Case series.

Academic medical center.

One hundred twenty-five patients underwent chin augmentation with solid silicone implants between 2004 and 2010. Among these implants, 105 were placed transorally. Eighty-five patients were followed for at least 1 year. Demographic information, indications, patient satisfaction questionnaire results, and complications were recorded.

All implants yielded satisfactory results with no displacement, infection, tissue reaction, lower lip incompetence, mental nerve injury, or intraoral implant contamination. Two cases of superficial mucosal irritation at the suture site were observed and resolved without consequence. Symmetry, projection, and overall balance of facial components were excellent. Although all patients were satisfied with the functional and aesthetic results, 20% stated they would like further augmentation. Patients were extremely satisfied with the lack of an external scar.

Based on our series, the intraoral technique with a midline incision avoiding disruption of the mentalis muscle is recommended for its ease, simplicity, patient satisfaction, low complication rate, and circumvention of an external scar. The external approach should be considered in cases that require a very large implant.
