The Specifics


What is an osseous genioplasty for chin deformity?

An osseous genioplasty for chin deformity is an invasive plastic surgery procedure to correct the bony aspects of the chin through an osteotomy (cut of a bone). The most common technique involves a horizontal osteotomy. The chin is formed by a bony protuberance from the mandible or lower jaw bone, and the most protruding aspect of the chin is called the pogonion.

In an osseous genioplasty for chin deformity, a plastic surgeon will alter and adjust this area to create the desired chin and jawline aesthetic using cephalometrics. Unlike alloplastic chin implants or soft tissue fillers, this plastic surgery fundamentally alters the bone and carries risk for disturbances to the mental nerve, inferior alveolar nerve, and mentalis muscle.

This technique can be used for severe chin deformities and plastic and reconstructive surgeries. A chin augmentation procedure is often combined with other surgical procedures such as rhinoplasty, liposuction, or a neck lift for further enhancements to the facial aesthetic.

What cosmetic concerns does an osseous genioplasty for chin deformity procedure treat?

  1. Chin Shape and Size: Changes made directly to the chin bone and soft tissues in an osseous genioplasty for chin deformity allow for significant alterations to chin shape and chin size.

Who is the ideal candidate for an osseous genioplasty for chin deformity procedure?

The ideal candidate for an osseous genioplasty for chin deformity has an overly projected chin requiring bone reduction, too tall or too short of a chin, macrogenia, microgenia, retrogenia, transverse asymmetries, or a severely retruded chin with horizontal deformities. Osseous genioplasty for chin deformity is not recommended for those with periodontal disease, lower lip protrusion, or those who have long teeth with short mandibular height, or other abnormalities of the tooth roots.

What is the average recovery associated with an osseous genioplasty for chin deformity procedure?

Acute recovery following an osseous genioplasty for chin deformity is generally one to two weeks. Most candidates feel comfortable resuming light activity after one week. Bruising, swelling, redness, and discomfort mostly resolve within the first seven days. A soft or liquid diet with minimal mouth and jaw movement will be recommended for one week. Overall, most side effects typically resolve within six weeks to six months.

What are the potential side effects of an osseous genioplasty for chin deformity procedure?

Possible side effects following an osseous genioplasty for chin deformity include bleeding, infection, bone resorption, nonunion of the bony segments after an osteotomy, wound dehiscence, and sensory changes due to damage to the mental nerve or inferior alveolar nerve of the face.

What can someone expect from the results of an osseous genioplasty for chin deformity procedure?

The results of an osseous genioplasty for chin deformity are permanent, and will be immediately noticeable following the chin augmentation plastic surgery. The final results will take 12 to 18 months to fully develop.

What is the average cost of an osseous genioplasty for chin deformity procedure?

An osseous genioplasty for chin deformity procedure can cost anywhere from $5,000 to $15,000. The actual cost of an osseous genioplasty for chin deformity is dependent upon location, board certified facial plastic surgeon, and length and involvement of the plastic surgery.

What to Expect


Osseous genioplasty or sliding genioplasty is a procedure performed to reshape the bony structure of the chin. Here is a quick guide for what to expect before, during, and after osseous genioplasty.

The Takeaway


An osseous genioplasty for chin deformity (a.k.a. a sliding genioplasty or mentoplasty) is a chin augmentation plastic surgery procedure used to correct various chin deformities such as chin ptosis, microgenia, macrogenia, and/or poor chin position. This orthognathic surgery can create significant results for high patient satisfaction, but does carry a high risk of injury to the mental nerve causing permanent changes in sensation.
