@fibroanestesia comes up with some interesting ideas.  Here they use a combination of the AScope3 (a disposable flexible video endoscope) and the King Vision video laryngoscope to perform a highly controlled intubation in a patient with an intrathoracic goitre.  They have obviously pre-assessed this patient and concluded that the risk of failed intubation or positional loss of the intrathoracic airway due to compression is minimal.
