Abstract:The author describe the endoscopically-assisted intraoral vertical ramus (IVRO) and subcondylar (ISCO) osteotomies for the treatment of symmetric mandibular prognathism. The use of the saw and the bone chisel under the continuous control of the endoscope provides a safer approach since the osteotomy is controlled during the whole process. The introduction of the endoscope to provide complete visualization of the osteotomy site may overcome the traditional limitations of direct visualization in IVRO and ISCO.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
