[Expert consensus on endoscopic surgery for the pediatric middle ear cholesteatoma based on the classification of cholesteatoma location].

Pediatric middle ear cholesteatoma is an aggressive keratotic lesion caused by abnormal proliferation of keratinised squamous epithelium in the temporal bone, with the characteristics of high postoperative recurrence rate, poor hearing effect and poor quality of life. Endoscopic surgery is able to deal with the majority of pediatric middle ear cholesteatoma cases with the features of minimal trauma and wide surgical field. However, endoscopic surgical treatment still has problems in standardization. In order to facilitate the development of endoscopic surgery for pediatric middle ear cholesteatoma, experts of the Endoscopic Ear Surgery Expert Committee and the Youth Committee of the Otorhinolaryngology Professional Committee, Chinese Association of Integrative Medicine discussed and formulated recommendations for the selection of endoscopic surgical and functional reconstruction methods of pediatric middle ear cholesteatoma based on the classification of cholesteatoma location in line with the clinical research results and diagnosis and treatment experience at home and abroad, aiming to provide guidance for the development of endoscopic surgery in pediatric setting.
