Abstract:With the development of endoscopic surgery technology,more and more applications have been made in the treatment of pediatric skull base lesions. However, due to the anatomical characteristics of children and the difficulty of surgery, this technology is not prevalent. This paper describes the development of pediatric transnasal skull base surgery, summarizes the anatomical characteristics of children's skull base, and the methods and characteristics of transnasal endoscopic skull base surgery including reconstruction of skull base, and forecasts the future direction of the diagnosis and treatment of pediatric skull base lesions.
