osteotomy

Full Definition

A surgical procedure involving the controlled cutting or reshaping of bone to correct structural abnormalities, improve function, or enhance aesthetics. In oral and maxillofacial surgery, osteotomies are commonly performed on the mandible and maxilla for orthognathic surgery, or on smaller bones for procedures such as genioplasty. The procedure requires precise planning, often with computer-assisted design, and careful execution to preserve vital structures while achieving desired outcomes.

Usage

Usage note: Distinguish from 'ostectomy' which refers to bone removal rather than cutting for repositioning.
