上颌切除患者术后发音障碍是重要问题,其主要原因是口腔与鼻腔交通,致使口腔、鼻腔共鸣失衡。安装义颌是改善发音最有效方法之一,通常涉及软腭切除病例改善效果不完全。该文对上颌不同类型缺损安装义颌前后发音方式、语音清晰度等进行了研究。 对象与方法 1980～1994年15年内,恶性或良性肿瘤行上颌切除患者54例,男26例,女28例,年龄19～84岁,平均57.6岁。仅行硬腭切除44例(Ⅰ组),
Obstructive maxillary resection patients with dysphonia is an important issue, the main reason is the oral and nasal traffic, resulting in oral, nasal resonance imbalance. The installation of the maxillary jaw is one of the most effective ways to improve the pronunciation, usually involving incomplete soft palate resection. This paper studies the different pronunciations and phonetic articulation before and after the installation of maxilla in different types of defects. Subjects and Methods In the 15 years from 1980 to 1994, 54 patients with malignant or benign tumors underwent maxillary resection, including 26 males and 28 females, aged from 19 to 84 years (average 57.6 years). Forty-four cases underwent hard palate resection (group Ⅰ)
