The use of the C-MAC videolaryngoscope for awake intubation in patients with a predicted extremely difficult airway: case series

Figures & data

Table 1 Description of cases

Case	Description	Comparison with the C-MAC view	Conclusion
1	A 62-year-old male underwent laryngoscopy in relation to further examination of the laryngeal inlet tumor	Fiber-optic evaluation before surgery	The views achieved by the C-MAC were similar to the fiber-optic one. The C-MAC may be used for examination of the airway before ENT surgery
2	A 59-year-old male underwent laryngoscopy in relation to further examination of the laryngeal tumor	CT scans before surgery	The C-MAC videolaryngoscope provided the laryngeal inlet view
3	An 85-year-old female with a laryngeal tumor underwent tracheostomy	CT scans before surgery	The C-MAC videolaryngoscope provided the laryngeal inlet view
4	A 55-year-old female was admitted to the hospital with difficulties in breathing	US of the larynx before surgery	The C-MAC videolaryngoscope provided the laryngeal inlet view
5	A 63-year-old obese male (1.78 m, 119 kg) who was admitted to the hospital with hoarseness	Clinical examination – indirect laryngoscopy	The C-MAC view provided a definite diagnosis
6	A 69-year-old male was admitted to the hospital with a tumor of the entry to the larynx for surgery	Fiber-optic evaluation	A videolaryngoscope provided better visualization of the laryngeal inlet than a fiber-optic scope
7	A 65-year-old male was admitted to the hospital for biopsy of a tumor of the laryngeal inlet	The McGrath series 5 view	The view achieved using the C-MAC was better
