OBJECTIVES: The purpose of this study was to evaluate the effectiveness of ablating postganglionic parasympathetic fibers of the submandibular ganglion in combination with sublingual gland excision in the treatment of primary sialorrhea.
MATERIALS AND METHODS: Healthy volunteers were initially chosen to determine a basic saliva flow rate value by saliva collection. Next, unstimulated and stimulated saliva flow rates, and a visual analog scale index for sialorrhea were recorded in all the patients pre- and postoperatively. In addition, the generalized anxiety disorder scale was used to assess preoperative anxiety symptoms. The follow-up durations ranged from 24 to 36 months after surgery.
RESULTS: A total of 10 patients were included in this study. Preoperatively, the mean unstimulated saliva flow rate for the 10 patients was 11.26 ± 4.19 ml/10 min, the stimulated saliva flow rate was 16.76 ± 3.49 ml/6 min, and the visual analog scale index was 66.29 ± 14.86. Postoperatively, the mean unstimulated and stimulated saliva flow rates were significantly reduced to 5.99 ± 1.33 ml/10 min (p = 0.001) and 13.28 ± 1.86 ml/6 min (p = 0.013), respectively, and the visual analog scale index was 25.41 ± 5.6 (p < 0.001). No complications were found after operation.
CONCLUSION: This study demonstrates that ablation of postganglionic parasympathetic fibers of the submandibular ganglion in combination with sublingual gland excision by an intraoral approach is a simple, safe, and efficient approach for treating primary sialorrhea.
