PURPOSE
To estimate the spontaneous recovery rate of isolated traumatic sixth-nerve palsy.
METHOD
A retrospective chart review over a 24-year period at a single institution, excluding patients who were first seen more than 6 weeks after injury, to reduce bias toward nonrecovery.
RESULTS
The Kaplan-Meier survival estimate of spontaneous recovery at 6 months was 27% (95% confidence interval [CI], 5% to 44%) in unilateral traumatic sixth-nerve palsy and 12% (95% CI, 0% to 33%) in bilateral traumatic sixth-nerve palsy.
CONCLUSION
Spontaneous recovery from isolated traumatic sixth-nerve palsy may be lower than previously reported. A prospective study is needed to provide a more accurate estimate of recovery rate.
目的
评估孤立性外伤性第六脑神经麻痹的自发恢复率。
方法
在单一机构进行为期24年的回顾性病历审查，排除受伤后6周以上首次就诊的患者，以减少对无恢复情况的偏倚。
结果
单侧外伤性第六脑神经麻痹6个月时自发恢复的Kaplan-Meier生存估计值为27%（95%置信区间[CI]，5%至44%），双侧外伤性第六脑神经麻痹为12%（95%CI，0%至33%）。
结论
孤立性外伤性第六脑神经麻痹的自发恢复率可能低于先前报道。需要进行前瞻性研究以更准确地估计恢复率。
