[Basis of endoscopic dissection of the ear with analysis of endoscopic anatomy. Part 2.].

Nowadays, endoscopic transcanal otosurgery with confident steps is becoming a practice. Obviously, any new method of intervention needs to be repeatedly tested by the surgeon before it is used on the patient. This is why dissection work is so important and popular. Working on biomaterial sets itself several tasks: training manual skills of working with an endoscope and an instrument in the middle ear cavities, stage-by-stage training for performing specific interventions, detailed analysis and repetition of anatomy and topography of structures. This article presents a step-by-step dissection algorithm with an analysis of the anatomical landmarks of each area, such as the prototype. The proposed training protocol allows practicing such interventions as endaural atticotomy, types of ossiculoplasty, stapedoplasty, decompression of the facial nerve to the geniculate ganglion area, infracochlear and transpromontorial approaches to the internal auditory canal.
