Résumé
Introduction Endolymphatic sac tumor (ELST) is a slow-growing, low-grade, locallyinfiltrative tumor arising from the endolymphatic sac/duct, which is located in the posterior part of the petrous temporal bone. It may be sporadic in origin, or may be associated with Von-Hippel Lindau (VHL) syndrome. Case description A 40-year-old female patient with an ELST without VHL syndrome who was treated successfully by microsurgical extirpation of the tumor. Discussion We discuss the radiological features and the histopathology of this rare tumor and review the relevant literature. Conclusion The case herein reported adds to the previously-reported cases of this rare tumor.

Background: Tympanoplasty is one of the commonest operations performed on the middle ear. Endoscopes are increasingly used for various middle ear surgeries. The objective was to determine merits and demerits of the endoscope as compared to the microscope in myringoplasty surgery and to compare the results of both group. Methods: Between the time period of January 2014 to September 2014, 44 patients underwent myringoplasty, 22 were endoscope assisted and 22 were microscope assisted. Results of surgery were compared at the end of 3 months post surgery. Results: In both groups, equal number of patients i.e. 15 (68.18%) had a successful outcome. Conclusion: Panoramic, wide angle, and magnified view provided by endoscope as well as ability to easily negotiate through EAC and provide uninterrupted image overcomes most of the disadvantage of microscope. In our study success rate was equal between endoscopic and microscopic technique. In terms of morbidity and postoperative recovery endoscope produced better results. Loss of depth perception and one handed technique are some of the disadvantage of endoscope that can be overcome with practice. Thus, Endoscopic tympanoplasty can be a good alternative of microscopic tympanoplasty.
