Sliding Genioplasty: Procedure, Recovery and Results
Updated: 2 days ago
Written and medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: November 2026 · How we review
Quick Answer
A sliding genioplasty, also called an osseous genioplasty, is surgery that reshapes the chin by cutting and moving part of the chin bone. It's mostly cosmetic but is also used for reconstruction. The incision is inside the mouth, so there's no visible scar. Most people return to work in 7 to 10 days.
What the research says
Chin surgery gave good cosmetic results: a review of 54 studies with 4,897 patients found all chin techniques gave satisfactory results; complications occurred in 19.7% after sliding genioplasty and 15.7% after implants, including temporary nerve numbness in 16.4% and 2.4% (Oranges CM et al., Plastic and Reconstructive Surgery, 2023) [2]
Chin advancement stayed stable: across 8 studies with an average chin advancement of 8.2 mm, bone shifted back only 0.1 to 2.1 mm after a year, so advancement genioplasty was predictable and stable (Janssens E et al., Journal of Cranio-Maxillo-Facial Surgery, 2021) [3]
Key takeaways
A sliding genioplasty reshapes the chin by moving bone.
The incision is inside the mouth.
It can move the chin forward, back or sideways.
Swelling lasts up to two weeks.
Most people return to normal activities in 7 to 10 days.
What is a sliding genioplasty?
The surgeon cuts the chin bone (osteotomy), repositions it and fixes it in place. To shorten a long chin, a piece of bone is removed; to lengthen a short chin, a gap is left for new bone to fill. A chin implant is an alternative for a small chin. Learn more about genioplasty. Sources: [1]

You usually get general anesthesia.
The surgeon makes an incision inside your mouth at the base of the jaw.

Infection.
Scarring.
Tingling or numbness in the chin or lower lip. Sources: [1, 2]

Swelling and bruising can last up to two weeks, and full recovery takes several weeks. Sources: [1]
Outlook
A sliding genioplasty improves facial balance and symmetry and can correct problems from birth, injury or past surgery. Studies show the results stay stable over time. Sources: [1, 3]
When to call your provider
Chest pain or shortness of breath.
Fever, chills or flu-like symptoms.
Pus or drainage from the incision.
