Résumé
Videoscopic study was applied in this work for 2 main purposes. Firstly, to diagnose the size of adenoids depending on fixed landmark, that is the posterior lip of the torus tubarius. This was done on 230 patients above 3 years old and resulted in classification of adenoids size into 3 degrees. First degree "normal" has its anterior limit behind the posterior lip of the torus. Second degree has its anterior limit in line with the posterior lip of the torus. Third degree has its anterior limit in front of the posterior lip of the torus [high indication of adenoidectomy]. Secondly, to perform adenoidectomy under magnified vision on monitor and this was applied on 86 patients. By this maneuver, trauma to Eustachian tube orifice and posterior nasopharyngeal wall was avoided, any remnants and control bleeding points could be removed. During the period of follow up of 1-3 years, no case developed complications of recurrence, postoperative bleeding and middle ear troubles
