The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



the surgical transection of bone to correct a deformity or to reposition a dislocation. Osteotomy can be linear, transverse, oblique, or curved. It is an open operation in which an incision just large enough to introduce the cutting instrument—an osteotome, chisel, saw, or ultrasonic osteotome—is made in the soft tissues under general or local anesthesia.

Though the causes of new TMJ symptoms in patients without preoperative symptoms are not known, one of the hypotheses proffered is the mechanical overload exerted on both the condyle and disc during manual repositioning of the ascending ramus in centric relation and during osteosynthesis, which results in excessive compression of the disc-condyle complex towards the posterior slope of the fossa, or from excessive rotation or tilting of the condyle due to bony interference between the proximal and distal bone fragments in sagittal split osteotomies, and/or from compression force elicited from osteosynthesis plates or screws.
