176 CHAPTER 8 Figure 1A. Drooling Quotient (DQ) and Visual Analogue Scale (VAS) at baseline, 8- and 32 weeks followup, after bilateral submandibular gland excision (SMGE) as a re-intervention SMGE as a re-intervention after DL When using a 50% decrease of DQ or VAS from baseline as the criterion for success, only two patients were considered successful (Table 3). Using a 50% decrease of DQ from baseline as the criterion for success, only one case could be considered successful. This was also the only patient who mentioned a decreasing drooling frequency score with a stable drooling severity score. MANOVA of repeated measures with the DQ as the within-participants variable showed no significant pattern over time (Hotelling’s trace: F=.476; df 1, 18.; p=.499).
