Abstract：
OBJECTIVE: To evaluate the effect of bulb height of hollow bulb obturator prosthesis on articulation and nasalance.
METHODS: A total of 10 patients, who were to undergo maxillectomy falling under Aramany class-I and II, with normal speech and hearing pattern were selected for the study. They were provided 2 maxillary obturators, one extending full height of the defect and other with bulb height approximately up to inferior nasal concha. The patients were asked to wear each obturator for 6 weeks and the speech analysis was done to measure changes in articulation and nasalance at 6 different stages of treatment i.e. preoperative, postoperative (after complete healing), 24h and 6 weeks after providing full bulb height obturator and reduced bulb height obturator. Articulation was measured objectively for distortion, addition, substitution and omission by speech pathologist and nasalance was measured by Dr. SPEECH software.
RESULTS: Comparison between full and reduced bulb height for nasalance and articulation, showed that there was no statistical significant difference (P>0.05) between the two for both the parametres.
CONCLUSIONS: Articulation and nasality improves after providing obturator. Articulation and nasalance both are independent of bulb height.

摘要：
目的：评价中空球型闭孔假体的球型高度对关节和鼻音的影响。
方法：共10例患者，他们将接受属于Aramany一级和二级的上颌骨切除术，选择具有正常言语和听力模式的人进行研究。他们提供了两个上颌闭塞器，一个延伸缺损的整个高度，另一个延伸的灯泡高度大约达到下鼻甲。要求患者佩戴每个闭孔器6周，并进行语音分析以测量在6个不同治疗阶段（即，术前，术后（完全愈合后），提供完整的灯泡高度闭塞器和降低的灯泡高度闭塞器后24小时和6周。关节是客观测量的失真，addition,言语病理学家的替换和遗漏以及鼻音由SPEECH博士软件测量。
结果：对于鼻音和关节的完整和降低的灯泡高度之间的比较，结果表明，两组参数之间的差异无统计学意义（P>0.05）。
结论：闭孔后，关节和鼻性改善。关节和鼻音都与灯泡高度无关。
