Correct placement of the swab and origins of the nasal bleeds in this study. The life-threatening bleeds resulted from the anterior ethmoid artery, 1 from the lateral and 1 from the medial nasal wall (blue asterisks). One bleed resulted from the sphenopalatine artery (black asterisk), and in 1 case, the bleeding site could not be identified.
