Novel Drill-burr Protection Sheath with Inbuilt Suction-irrigation for Endoscopic Ear Surgery.

We have developed a novel instrument which is a drill burr protection sheath with an inbuilt suction-irrigation system for endoscopic ear surgery. It allows simultaneous suction and irrigation. It is a metallic attachment onto the mastoid drill handpiece. It provides protection for the endoscope as well as the external auditory skin during transcanal drilling procedures. It is cost effective. 5. The online version contains supplementary material available at 10.1007/s12070-021-02944-8.
