Pharyngeal size, compliance, and the dynamic behavior of the upper airway are important factors in the production of obstructive sleep apnea. Assessment of the upper airway for possible site(s) of obstruction is one of the keys to a successful management of the condition. Acoustic pharyngometry has the potential for localizing such sites, however, standardizing the operating technique and producing a standard normal curve is a prerequisite before exploring the potential of this equipment. A total number of 350 normal volunteers (271 males and 79 females) were examined by acoustic pharyngometry and a coefficient of variance of 5% to 7% was obtained from each of them. Mean and standard deviation of pharyngeal area at each point of X-axis (distance) was obtained and analyzed statistically to produce a general standard curve. Using special techniques during examination, the oropharyngeal junction and glottis were located, and thus a mapped acoustic pharyngogram was produced. Mean pharyngeal area was 3.194 cm(2) in males (SD 0.311) and 2.814 cm(2) in females (SD 0.331). Mean glottic area was 1.06 cm(2) in males (SD 0.119) and 0.936 cm(2) in females (SD 0.108). A minimal pharyngeal area is probably needed as a "golden standard" to evaluate patients with obstructive sleep apnea.
咽部大小、顺应性以及上气道的动态行为是导致阻塞性睡眠呼吸暂停的重要因素。评估上气道可能的阻塞部位是成功治疗该疾病的关键之一。声学咽测量法有定位这些部位的潜力，然而，在探索该设备的潜力之前，标准化操作技术并绘制标准正常曲线是一个先决条件。对350名正常志愿者（271名男性和79名女性）进行了声学咽测量，每人获得的变异系数为5%至7%。获取X轴（距离）各点处咽部面积的均值和标准差，并进行统计分析以绘制通用标准曲线。在检查过程中使用特殊技术定位口咽交界处和声门，从而绘制出映射声学咽图。男性的平均咽部面积为3.194平方厘米（标准差0.311），女性为2.814平方厘米（标准差0.331）。男性的平均声门面积为1.06平方厘米（标准差0.119），女性为0.936平方厘米（标准差0.108）。可能需要一个最小咽部面积作为“金标准”来评估阻塞性睡眠呼吸暂停患者。
