Figure 5:

Scatterplots showing the relationship between lesion size and change in functional ratings for left-right phase asymmetry (a,b) and vocal fold edge (c,d) following phonomicrosurgery. Epithelial (a,c) and subepithelial lesions (b,d) are presented separately. Negative numbers on the x-axis indicate an improvement in function following surgery, positive numbers indicate a decline 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).
