Management of attic cholesteatoma
In the treatment of cholesteatoma in upper attic, endoscopic approach and microscopic approach have the same therapeutic effect in this study. Endoscopic approach and microscopic approach have the same operation time. Microscopic surgery takes less time than endoscopic surgery in a study by Magliulo et al.3 In order to ensure that the surgical field of vision is wide enough in one-handed endoscopic surgery, it takes more time to stop bleeding, which will lead to an increase in the chance of leaving residual lesions when the surgical field of vision is low, and the critical structures are in danger. The operation time of endoscopic approach will be shorter in other studies, which is due to better understanding and familiarity with surgical anatomy and techniques.5
8 In the early systematic review of EES and MES patients, the success rate and hearing results of 8 tympanic transplants can be compared experimentally. The taste, postoperative vertigo, air-bone space, average healing time and long-term prognosis have been proved to have no significant difference. Magliulo et al. have made a similar research conclusion on the statistical difference between the two surgical techniques in terms of postoperative pain and healing time.3,5
