Study Design
We performed a prospective observational study, amongst a cohort of 150
consecutive SL procedures for suspected benign laryngeal pathology, in
our tertiary adult airway service. We recorded the grade of surgical
view obtainable by SL according to our current practice (Figure 1), as
well as the minor and major complication incidences, over an 8-month
period between November 2019 and July 2020.
