in difficult-to-intubate patients with successful
endotracheal tube placement as the primary endpoint.
Customizable VLs may be very useful as one of the
tools in the elective airway management of pediatric
patients with complex craniofacial malformations,
especially when fiberoptic intubation was attempted
and failed.

FIG 5
To our knowledge this is a first study of customizable
VLs in which the shape, length and angulation can be
preoperatively adjusted based on the airway anatomy
of each patient. The availability of inexpensive
pressure-sensitive tablets, 3-D printing and cheap
camera/LED light mini-endoscopes makes the design
and preparation of such customizable VLs possible.
Since the cost of materials was less than $20, these
devices can be disposable. The mini-endoscope
can be attached to any laptop computer, tablet or
cell phone. Therefore, the purchase of expensive
commercial imaging equipment is not needed.
