Figure 4:

Scatterplots showing the relationship between lesion size and change in functional ratings for mucosal wave (a,b) and amplitude (c,d) following phonomicrosurgery. Epithelial (a,c) and subepithelial lesions (b,d) are presented separately. Positive numbers on the x-axis indicate an increase in function following surgery, negative numbers indicate a decrease in function following surgery, and vertical lines indicate the effective error of the visual-perceptual scale. Solid symbols represent patients measured using high-speed dynamically interlinked with digital kymography line scans (HSV+DKG) that could not be measured using videostroboscopy (VS).
