An important question remains on how to obtain good quality of speech for patients needing maxillectomy. Oral and nasal spaces must be separated either by surgical means or by using an obturator-prosthesis. An objective measure of oronasal closure is nasalance. Different rehabilitative strategies should be compared.
Between 1990 and 2000, 88 patients underwent maxillectomy of which 28 (32%) were available for examination. Ten patients had obturators (group l) and in 18 patients the maxilla was biologically reconstructed with different techniques (group 2). Sound pressure of nasal and oral airways were assessed seperately using a computerized sampling system (NasalView) and standardized German texts. Nasalance was calculated and compared with an uncompromised sample of patients.
There were no significant differences between group 1 and group 2 concerning nasalance. Furthermore, the achieved values of nasalance were similar to healthy individuals.
Nasalance after maxillectomy can be normal after sufficient rehabilitation.
对于需要进行上颌骨切除术的患者，如何获得高质量语音仍是一个重要问题。口腔和鼻腔空间必须通过手术方式或使用阻塞器假体来分隔。鼻漏气是口鼻闭合的一种客观测量方法。应比较不同的康复策略。
1990年至2000年间，88例患者接受了上颌骨切除术，其中28例（32%）可供检查。10例患者使用阻塞器（第1组），18例患者采用不同技术对上颌骨进行生物重建（第2组）。使用计算机采样系统（NasalView）和标准化德文文本分别评估鼻腔和口腔气道的声压。计算鼻漏气率并与未受影响的患者样本进行比较。
第1组和第2组在鼻漏气率方面无显著差异。此外，所获得的鼻漏气率值与健康个体相似。
经过充分康复后，上颌骨切除术后的鼻漏气率可以恢复正常。
