切断颌下神经节节前副交感神经纤维治疗原发性流涎症

Amputation of submandibular preganglionic parasympathetic fibers in the treatment of primary sialorrhea

目的：探讨切断颌下神经节节前副交感神经纤维治疗原发性流涎症的疗效。方法 ：2010年1月至2013年1月间我院收治的原发性流涎症患者31例,均行切断单侧颌下神经节节前副交感神经纤维术,对所有患者在术前和术后行静态唾液总流率测定的客观评价以及流涎症状情况的主观症状评价,并随访观察并发症的发生情况。结果：通过15-39个月随访,31例患者中,客观评定有效率为96.78%（30/31）,主观评定有效率为93.55%（29/31）,在随访期无复发病例,未见有明显的并发症发生。结论：切断颌下神经节节前副交感神经纤维是治疗原发性流涎症简单易行、安全有效的方法。

Objective：To investigate the therapeutic effect of amputation of submandibular preganglionic parasympathetic fibers on primary sialorrhea. Methods：One-side submandibular preganglionic parasympathetic fibers amputation was performed on 31 patients with primary sialorrhea in our hospital from January 2010 to January 2013. Preoperative and postoperative static total saliva flow rate and subjective symptoms of sialorrhea were detected and recorded and the occurrences and complications were followed up. Results：Within 15-39 months follow-up,the objectively evaluated efficiency was 96.78%（30/31）while the subjectively evaluated efficiency was 93.55%（29/31）by the 31 patients. No recurrence and no complication occurred. Conclusion：Amputation of submandibular preganglionic parasympathetic fibers is a simple,safe and effective method for primary sialorrhea.
