The level of sensory recovery was studied in 13 consecutive patients who had undergone lingual nerve repair after a delay of 7-32 (mean 16) months since the initial injury. In all patients the damaged segment of nerve was excised and the cut ends directly apposed by 6-10 (mean 7) epineurial sutures. The final outcome was assessed 12-24 months after repair. Preoperatively none of the patients could detect light touch stimuli in the denervated area, whereas 10 patients could detect some stimuli after repair. Pin-prick was detected in 6 preoperatively and in some areas by all 13 patients after repair. Two-point discrimination thresholds decreased after repair in 10 patients and in four of these became the same as on the uninjured side. Gustatory stimuli showed that there had been some return of taste sensation in 6 patients, and there were responses to electrogustometry in 12 patients. The patients' subjective assessment of the value of repair (scale 0-10) ranged from 0-10 (median 7). These results show that most patients undergo significant and worthwhile recovery after late lingual nerve repair.
对13例连续性患者进行了感觉恢复水平的研究，这些患者在初次受伤后7至32个月（平均16个月）延迟进行了舌神经修复。所有患者均切除了受损的神经节段，切断端通过6至10针（平均7针）的神经外膜缝合直接对合。修复后12至24个月评估最终结果。术前，所有患者在失神经支配区域均无法检测到轻触觉刺激，而修复后有10例患者能检测到一些刺激。术前6例患者能检测到针刺觉，修复后所有13例患者在某些区域均能检测到针刺觉。10例患者修复后两点辨别阈值降低，其中4例与未受伤侧相同。味觉刺激显示，6例患者味觉有一定程度的恢复，12例患者对电味觉测试有反应。患者对修复价值的主观评估（0至10分）范围为0至10分（中位数为7分）。这些结果表明，大多数患者在晚期舌神经修复后有显著且有价值的恢复。
