Nasal speculum for submental intubation

In 1986 Altemir, for the first time, described submental intubation for maxillofacial cases. 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
