distraction osteogenesis
A surgical technique that gradually lengthens or reshapes bone by controlled mechanical distraction to generate new bone tissue.
Full Definition
Distraction osteogenesis is a reconstructive procedure used in plastic surgery to lengthen or reshape bones, particularly in craniofacial reconstruction. The process involves making a controlled osteotomy (bone cut) and then gradually separating the bone segments using a specialized device called a distractor. As the bone segments are slowly pulled apart, new bone tissue forms in the gap through the body's natural healing response. This technique is commonly used for mandibular lengthening, correction of facial asymmetry, and treatment of various congenital craniofacial deformities.
Usage
Usage note: Two words, no hyphen; distinct from simple bone distraction procedures.
