摘要
目的探讨数字化赝复体术中修复BrownⅡ类缺损后的功能及面容恢复程度。方法 2016年8月至2017年8月收治10例因肿瘤致BrownⅡ类缺损患者;对其行术中赝复体修复。术后1、3、6个月分析语音清晰度、吞咽功能、咀嚼功能、面容对称性。结果赝复体修复后1、3、6个月语音清晰度显著提高(P=0.004、0.015、0.001,P<0.05);吞咽功能提高1~2级,有效率25%(2/8),显效率75%(6/8);口角偏斜角度、双侧唇部高度差、最大偏差距离、变化区域体积显著减小(P=0.007、0.044、0.039,0.042,P<0.05);患侧牙合力比值(20.45±2.55)%,健侧牙合力比值(79.55±2.55)%,牙合力不对称指数(59.10±5.09)%,患侧牙合力恢复指数范围(25.82±4.04)%。结论数字化赝复体术中修复BrownⅡ类缺损可获得良好的面容及功能恢复。
Objective To assess function and facial appearance after instant rehabilitation of BrownⅡmaxilla defect with digital prosthesis. Methods Due to tumor resection, 10 patients with Brown Ⅱ maxilla defect were treated with prosthesis from August, 2016 to August, 2017 in operation. The speech intelligibility, swallowing function, masticatory function and facial symmetry were evaluated 1 month, 3 months and 6 months after operation. Results Speech intelligibility was improved significantly via prosthesis rehabilitation 1 month, 3 months and 6 months after operation(P=0.004, 0.015, 0.001, P<0.05). The effective rate and apparent rate of swallowing were respectively 25%(2/8) and 75%(6/8). The skewed degree of mouth corner, the difference of bilateral lip height, the maximum deviation distance and the change area volume decreased significantly(P=0.007, 0.044, 0.039, 0.042, P<0.05). The ratios of biting force were(20.45±2.55)% and(79.55±2.55)% in affected and normal sides. Asymmetric index of biting force was(59.10±5.09)%. Biting force in affected side was recovered to(25.82±4.04)%. Conclusion Digital prosthesis can repair Brown maxillaⅡdefect in surgery with excellent rehabilitation of facial appearance and function.
