PPE for Otologic Surgery
Data concerning viral burden in the middle ear and mastoid cavity is lacking, though historical studies have found coronavirus RNA in middle ear fluid. 29 Recommendations have been made for enhanced eye (i.e. tight-fitting goggles or PAPR) protection when drilling is performed, which have been related to reports of transcorneal penetration of bone dust during mastoidectomy demonstrated in an experimental setting 30, and the distinct uncertainty surrounding, but persistent suspicion of, viral aerosolization with bone drilling. In light of the available data, at least standard airborne precautions should be followed on COVID-positive or suspicious patients undergoing otologic surgery.
