Video Description

This video covers the key steps of a lateral temporal bone resection during lab dissection of the temporal bone.  The goal of this video is to serve as a supplementary teaching resource for resident-level surgical trainees by demonstrating key surgical landmarks and proper lab dissection technique. This video builds on part two of our video series. This approach allows for the en bloc removal of the external auditory canal and demonstrates fundamental steps of the procedure including: the propagation of a superior trough between the tegmen and the superior aspect of the external auditory canal, the extension of the facial recess inferiorly with sacrifice of the chorda tympani, and the drilling of the hypotympanic bone towards the glenoid. At the completion of the demonstration, the viewer is afforded a labelled view of the medial wall of the mesotympanum, as well as the medial aspect of the external auditory canal with an intact tympanic membrane. Key surgical landmarks demonstrated in the course of this video include: tegmen, zygomatic root, malleus, incus, stapes, glenoid, eustachian tube, mastoid segment of the facial nerve, chorda tympani nerve, facial recess, hypotympanic space, annular bone, tensor tympani tendon, cochlear promontory, pyramidal process, round window, and lateral semicircular canal.
