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.
