A problem with the technique is that the edges of the tube may damage the anatomic tissues of the mouth floor. To avoid such damages, a modification of this technique using nasal speculum is presented here. Moreover, with this technique blood and detached tissues cannot enter into the endotracheal tube while passing through submental tissues. https://jcr.tums.ac.ir/index.php/jcr/article/view/85 https://jcr.tums.ac.ir/index.php/jcr/article/download/85/53
