摘　　要：为探讨定量评价喉癌患者行垂直半喉切除术后鼻音变化的方法，选择30例行此术患者按术后时间长短分A、B两组，采用鼻声图仪行声功能检测；并以30例正常人（C组）作对照。结果示：三组鼻音句与非鼻音句的鼻音强度无显著性差异（均P＞0．05）；而〔i：〕音鼻音率A、B两组显著低于C组（分别P＜0．001和P＜0．05），A组又显著低于B组（P＜0．01）。表明喉癌患者行垂直半喉切除术后声功能下降明显，但随时间延长，声道的解剖关系和质地逐渐改善，鼻音率也逐渐向正常发展。提示鼻声图仪可客观定量地评价喉癌患者行垂直半喉切除术后的鼻音变化，进而判断其疗效。It was important and requisite how to quantitatively evaluate nasalance after vertical hemilaryngectomy in patients with carcinoma of the larynx. The lately invented instrument nasometer, which can evaluate objectively vocal function, were used to determine separately in 30 healthy adults and 30 patient's with laryngeal carcinoma treated primarily by vertical hemilaryngectomy from 1984 to 1994. The results showed that the determined nasalance, have significant difference among surgical groups and normal group (P <0.00l and P <0.05). We also found that the determined values of nasalance have significant difference between postoperative two years and postoperative ten years groups (P <0.01 ). It proved that the longer postoperative time, the better the patient's vocal function.
