Setup and Safety of Powered TEES

This chapter will expand on Chap.  2 which focused on powered transcanal endoscopic ear surgery (TEES) by looking at the surgical setup and safety concerns related primarily to powered TEES as well as what was referred to in Chap.  2 as “non-powered TEES.” To reiterate “non-powered TEES” is not a general term used in the literature and is used here to refer to what is typically simply called TEES. Successful TEES, in general, and powered TEES, specifically, requires careful preparation including procuring the proper equipment together with properly positioning and preparing that equipment, the surgical staff, and the patient. The safety issues which also need to be addressed for powered TEES include proper use of the powered instruments within the middle ear, heat generation of light sources, and the potential impact of skull vibrations generated by these powered instruments.
