class 3 division
editI want to propose the comarck 3a and 3b classification. We can see on the miller textbook, 7th edition:
"The most useful modification is a subclassification of grade 3 into 3a when the epiglottis can be lifted from the posterior pharyngeal wall and 3b when it cannot be lifted."
Indeed this is true, and in fact, it is more important whether the epiglottis can be lifted or not, rather than the vocal cords or arithenoids are fully seen (2a/2b)
There is evidence to this here: Refs: 1. Henderson J (2010). Airway Management in the Adult. In RD Miller et al., eds., Miller's Anesthesia, 7th ed., p. 1570. Philadelphia: Churchill Livingstone. 2. Cook TM: A new practical classification of laryn-geal view. Anaesthesia 55:274-279, 2000. (HelenoBR (talk) 03:28, 27 April 2014 (UTC))
