To evaluate speech following prosthetic obturation of surgically acquired maxillary defects, the speech intelligibility of eight patients was measured preoperatively and postoperatively, with and without prostheses. Oro-nasal separation and velopharyngeal function were also evaluated by use of a specially designed spirometer and endoscope. Following placement of maxillary obturator prostheses, four patients achieved dramatic improvement in speech intelligibility, while four patients did not. In the latter, insufficient improvement in speech intelligibility was attributed to velopharyngeal incompetence or unstable prosthesis. Two of three patients with velopharyngeal incompetence did achieve adequate improvement in speech following placement of a speech appliance in combination with maxillary obturator prostheses.
为评估手术造成上颌骨缺损后使用修复体阻塞后的言语情况，对8例患者在术前和术后佩戴及不佩戴修复体时的言语清晰度进行了测量。还使用专门设计的肺活量计和内窥镜评估了口鼻分离和腭咽功能。在上颌阻塞性修复体植入后，4例患者的言语清晰度有显著改善，而4例患者没有改善情况。对于后者，言语清晰度改善不足归因于腭咽功能不全或修复体不稳定。在3例腭咽功能不全的患者中，有2例在佩戴语音矫治器联合上颌阻塞性修复体后言语得到了充分改善。
