Static two-point discrimination, pressure, and vibratory threshold values were measured at standard coordinates in the area corresponding to the infraorbital nerve distribution in 59 adolescents 1 year after undergoing LeFort I osteotomy. The patients were divided into three groups: those born with unilateral cleft lip and palate (n = 30; mean age, 18 years; SD = 2); those with bilateral cleft lip and palate (n = 12; mean age, 19 years; SD = 3); and those without a cleft (n = 17; mean age, 19 years; SD = 3). One year after the osteotomy, none of the patients complained of altered sensibility in the maxillary vestibular mucosa, gingiva, or upper lip and cheek regions. No significant differences were found between the mean postoperative sensibility values of patients with and without clefts, indicating that the presence of clefting did not affect sensory recovery. Mean postoperative static two-point discrimination values were higher than preoperative values in all areas tested and in all patient groups. These results suggest that the sensory recovery, although incomplete, was strong enough to mask any subjective feelings of changes in sensory function.
在59名青少年接受LeFort I截骨术1年后，于对应眶下神经分布区域的标准坐标处测量静态两点辨别觉、压力觉和振动觉阈值。患者被分为三组：单侧唇腭裂患者（n = 30；平均年龄18岁；标准差 = 2）；双侧唇腭裂患者（n = 12；平均年龄19岁；标准差 = 3）；以及非腭裂患者（n = 17；平均年龄19岁；标准差 = 3）。截骨术后1年，没有患者抱怨上颌前庭黏膜、牙龈或上唇及颊部区域感觉改变。有腭裂和无腭裂患者的术后平均感觉值之间未发现显著差异，表明腭裂的存在并不影响感觉恢复。在所有测试区域和所有患者组中，术后静态两点辨别觉的平均数值均高于术前数值。这些结果表明，感觉恢复虽然不完全，但足以掩盖任何关于感觉功能变化的主观感受。
