Chin surgery: II. Submental ostectomy and soft-tissue excision.

At the present time, surgical reduction of an isolated large chin is not a simple procedure. Essentially, two surgical procedures exist for chin reduction: osteotomy with setback or prominence reduction by burring. Both of these procedures have potential negative aesthetic sequelae, including mental nerve injuries, bony contour irregularities, increasing submental soft-tissue fullness, and chin pad ptosis. In this report, the authors present a new approach to chin reduction: submental ostectomy with soft-tissue excision. This technique reduces the prominent chin and avoids ptosis by soft-tissue adjustment.
