Abstract:

Objective　To select the best predictor of swallowing functions by exploring the correlation between the swallowing function and tongue mobility and tongue pressure of the patients with tongue defects after oral cancer surgery or oropharyngeal cancer surgery. Methods　From July 2017 to March 2018，in Hospital of Stomatology，Sun Yat-sen University，thirty-six cases of patients with tongue defects after oral cancer surgery or oropharyngeal cancer surgery were collected during return visits in the outpatient clinics of our hospital. The swallowing functions were graded by their water swallowing test（WST）results. The tongue mobility scores were evaluated by using the lingual range of motion（LROM）method，while the tongue pressure was measured by using the Iowa oral performance instrument（IOPI）. Spearman rank correlation analysis was applied to calculate the rank correlation coefficient（rs） between the tongue mobility scores or tongue pressure and WST results，and the corresponding P value. Results　The rs value between WST results and tongue mobility scores or tongue pressure was -0.575 and -0.613 respectively（P＜0.05）. The rs value of tongue pressure was larger than that of tongue mobility scores. Conclusion　Both the tongue mobility scores and tongue pressure have a great impact on the swallowing functions of patients with tongue defects after oral cancer surgery or oropharyngeal cancer surgery，and tongue pressure is the best predictor.

摘要：

目的　探讨口腔癌及口咽癌术后伴舌缺损患者吞咽功能与舌动度及舌压的相关性，筛选吞咽功能最佳预测指标。方法　选取2017年7月至2018年3月于中山大学附属口腔医院口腔颌面头颈肿瘤外科门诊复诊的口腔癌及口咽癌术后伴舌缺损患者36例，通过洼田饮水试验对其吞咽功能进行评级，应用舌运动范围法对其舌动度进行测量评分，同时利用爱荷华口腔行为仪测量其舌压。采用Spearman秩相关分析方法计算洼田饮水试验等级与舌动度评分及舌压之间的秩相关系数（rs）及相应的P值。结果　舌动度评分及舌压与洼田饮水试验等级的rs分别为-0.575和-0.613（均P＜0.05）；其中舌压与洼田饮水试验等级的rs值较舌动度评分的rs大。 结论　舌压与舌动度均可影响口腔癌及口咽癌术后伴舌缺损患者的吞咽功能，其中舌压是评估患者吞咽功能的最佳预测指标。
