Participants
The research team conducted structured interviews with 6
Otolaryngologists operating at BCCH. The participating surgeons included
4 senior consultants and 2 surgical fellows. The sample size was limited
due to the number of surgeons who had regular access and experience with
the 3D endoscopy equipment. Previous research has demonstrated that a
qualitative sample size is best determined by the nature of individual
study rather than a power calculation4–6.
