Submental intubation — Practical alternative airway in maxillofacial surgeries

Submental intubation in oral and maxillofacial surgery: a systematic review 1986–2018

“…Modifications included awake conversion from oral to submental intubation (n = 12), 46 use of a dilator instead of dissection to enlarge the submental passage (n = 7), [47][48][49] and a retrograde technique with an adjunctive pharyngeal loop for restricted mouth opening (n = 1). 50 Exteriorisation may be facilitated by a guiding tube (n = 34), 26,51,52 or by the use of a nasal speculum (n = 3), malleable retractor (n = 1), double curved artery forceps (n = 3) 53 or the two-forceps technique (n = 5) 54 to maintain patency of the submental passage; or by covering the end of the tube to maintain its patency (n = 35). 38,[55][56][57] Covering the end of the second tube before insertion orally was also described.…”
