Six patients who had undergone partial maxillary resection for the removal of oral neoplasms were studied. For each patient two types of obturators were made one being buccal flange and the other hollow-bulb. Speech evaluations were made under three conditions: 1- with the hollow-bulb 2- with the buccal flange and 3- with no obturator. Speech evaluations were made both audiovisually and from tape recordings. In both audiovisual and tape recorded speech evaluations, the buccal flange obturator produced speech which was significantly superior to speech with hollow-bulb obturator.
对6例因口腔肿瘤切除而接受部分上颌骨切除术的患者进行了研究。为每位患者制作了两种类型的阻塞器，一种是颊侧翼缘型，另一种是空心球型。在三种情况下进行语音评估：1. 使用空心球型阻塞器；2. 使用颊侧翼缘型阻塞器；3. 不使用阻塞器。通过视听和录音两种方式进行语音评估。在视听和录音语音评估中，颊侧翼缘型阻塞器产生的语音明显优于空心球型阻塞器产生的语音。
