Genioplasty
Pronunciation: jee-nee-oh-PLAS-tee
A surgical procedure that repositions or reshapes the chin bone (the mandibular symphysis) to correct skeletal chin deformities or improve facial balance.
Full Definition
Genioplasty, also called mentoplasty when involving soft-tissue augmentation, is a surgical procedure in which the anterior segment of the mandibular symphysis is osteotomised and repositioned to alter chin projection, height, or symmetry. It is commonly performed in conjunction with orthognathic surgery or as a stand-alone aesthetic procedure. In editorial contexts, 'genioplasty' specifically refers to the osseous procedure, while 'chin augmentation' typically denotes alloplastic implant placement; the two must not be used interchangeably. Operative reports, referral letters, and insurance pre-authorization documents must use the correct term to reflect the specific surgical technique performed.
Usage
Usage note: Distinguish carefully from 'chin augmentation'; genioplasty involves bone movement, whereas augmentation typically implies an implant.
In Context
- "The treatment plan outlined a combined bilateral sagittal split osteotomy and genioplasty to address the patient's skeletal Class III malocclusion with chin asymmetry." — Surgical Treatment Plan
- "The editor queried whether the author intended 'genioplasty' or 'chin augmentation', as the operative note described insertion of an alloplastic implant." — Manuscript Peer Review
