Quantitative evaluation of oral function in acute and recovery phase of idiopathic facial palsy

周围性面瘫患者经常抱怨进餐时液体渗漏和食物滞留。我们调查了患有周围性面瘫的成年人进食时的口腔功能。在研究1中，通过测量咀嚼后口腔前庭中残留的米量来评估口腔前庭清洁能力。在研究2中，通过测量咀嚼过程中从胶状果冻中洗脱出的葡萄糖来评估咀嚼效率。结果：面瘫患者首次就诊时口腔前庭清洁能力明显下降，但随着面肌功能的改善而恢复。瘫痪的改善和食物滞留的减少之间存在显著的相关性。口腔前庭清洁能力比咀嚼效率与面部肌肉功能的相关性更显著。我们的数据表明，周围性面瘫会损害进食，恶化口腔卫生，这可能会导致口腔疾病。

Patients with peripheral facial palsy frequently complain of fluid leakage and food retention during meals. We investigated oral function during eating in adults with peripheral facial palsy.In Study 1, oral vestibular cleansing capability was assessed by measuring the amount of rice remaining in the oral vestibule after mastication. In Study 2, masticatory efficiency was evaluated by measuring glucose eluted from gummy jelly during chewing. Result : Oral vestibular cleansing capability at the first visit was significantly decreased by facial palsy but recovered as facial muscular function improved. There was a significant correlation between improvement in paralysis and decreased food retention. Oral vestibular cleansing capability was more significantly associated than masticatory efficiency with facial muscle function. Our data suggest that peripheral facial palsy impairs eating and worsens oral hygiene, which may result in oral disease.
