摘要
目的:评价上颌骨切除术后,患者的语音清晰度情况以及影响语音清晰度的相关因素。方法:选择因肿瘤行上颌骨切除的36例患者为研究对象,采用中空上颌赝复体修复缺损部分,用主观语音清晰度测试法,测试患者戴赝复体前后的语音清晰度值SI,并分析下列因素对其语音清晰度的影响:(1)口腔与鼻腔相通情况;(2)硬腭切除范围;(3)软腭缺损情况;(4)口内余留基牙。结果:36例患者未戴入赝复体时的SI均值为41.3±10.6%,戴入赝复体的SI均值为89.6±7.7%,两者具有显著性差异。多元回归分析结果显示,在各因素的综合作用下,口鼻腔穿通情况对未戴用赝复体患者的SI值有显著的影响(P<0.01);软腭缺损对戴用赝复体后的SI值有显著影响(P<0.01)。结论:口鼻腔穿通是影响戴赝复体前语音清晰度的因素之一,软腭缺损是影响戴赝复体后语音清晰度的因素之一。
Objective： To evaluate the influences ofmaxillofacial obturator prostheses on the speech intelligibility （SI） of patients with maxillary defect. Methods： 36 patients with maxillary defect were collected in this study and received obturator prosthesis for maxillary rehabilitation. The speech intelligibility test was conducted to evaluate the postoperative articulatory function. The relationships between the following factors and SI scores were analyzed： （1） An oro-nasal communication; （2） Hard-palate resection; （3） Soft-palate resection; （4） Retention teeth for a maxillary prosthesis. Results： The mean SI score without prosthesis in all patients was 41.3± 10.6% and that with prothesis was 89.6 ±7.7%. Multiple regression analysis of interactions between each factor and SI scores revealed that oro-nasal communication had a highly significant influence on SI scores without a prosthesis（P〈0.01）and soft-palate resection had a highly significant influence on the SI scores with a prosthesis（P〈0.01）. Conclusion： Oro-nasal communication is one of the factors that influence SI without a prosthesis and the resection of the anterior portion of the soft palate is one of factors that influence SI with a prosthesis.
