舌神经修复效果及评价方法的初步研究

本研究目的是评价舌神经吻合后舌前２／３感觉和味觉恢复的情况。应用神经外膜吻合修复舌神经损伤１４例，初步研究结果表明：①舌神经重度损伤后，患侧舌前２／３菌状乳头大多萎缩、消失，感觉和味觉严重障碍；②神经外膜吻合修复舌神经，菌状乳头可以再生，术后一年，５０％患者感觉恢复正常，３５．７１％患者味觉恢复正常；③感觉功能检查、味觉功能测定、菌状乳头及其味孔定量观察评价舌神经的损伤和修复，结果是客观、准确、可靠的。

Evaluating methods and effects of repairing injured lingual nerves on human

We evaluated the regenerations of sense and taste on the anterior 2/3 of the tongue following repairing injured lingual nerve. Injured lingual nerves in 14 patients were repaired with anastomosis of the nerve epineurium. On the anterior 2/3 of the ipsilateral tongue, most of the fungiform papillae atrophied and disappeared, the sense and taste degenerated after severe injury to lingual nerve. Following repair of the injured lingual nerve with anastomosis of nerve epineurium, the papillae and their taste pores can regenerated, 50% of the patients recovered their tongue sense and 35.71% of the patients recovered their tongue taste 1 year after the repair. It is objective, accurate and reliable to evaluate the regenerations of sense and taste on the anterior 2/3 of the tongue after repair of injured lingual nerve by sensory test, taste evaluation, quantitative observation of fungiform papillae, and their taste pores.
