Twenty patients with hypernasal speech were studied with both flexible fiber optic nasopharyngoscopy and multi-view videofluoroscopy, as well as behavioral speech assessment. Characteristic diagnostic findings showed the hypernasality to be caused by hypertrophic tonsils with posterior placement of the upper poles of the tonsils into the oropharyngeal and nasopharyngeal airway. In 16 of the 20 cases, there was a complete resolution of hypernasal speech following only tonsillectomy with no other treatments. Three patients required a brief period of speech therapy and one additional patient required both speech therapy and temporary prosthetic treatment (speech bulb reduction).
对20名鼻音过重的患者进行了研究，采用了可弯曲纤维光学鼻咽镜检查、多视角电视荧光透视检查以及行为言语评估。特征性诊断结果显示，鼻音过重是由扁桃体肥大导致的，扁桃体上极向后移位至口咽和鼻咽气道。在这20例病例中，有16例仅行扁桃体切除术后，鼻音过重的症状就完全消失，无需其他治疗。3例患者需要短期的言语治疗，另有1例患者既需要言语治疗，也需要临时的修复治疗（减小语音球）。
