To measure the airway obstruction caused by adenoid hypertrophy in the sitting and recumbent positions in search of hypothesized differences.
Forty eight children between the ages of 2 and 12 years who sought the department of otorhinolaryngology spontaneously complaining of snoring and/or nasal obstruction. Children could be either male or female and belong to any social or racial group. Patients underwent nasal videoendoscopy sitting and lying performed by the same investigator. An image of the posterior nasopharynx was obtained from each nasal cavity of each patient for both positions. The free area of the nasopharynx was measured and compared in both positions. Image analysis was performed by two researchers other than that who carried out the examination.
The nasopharynx free area obtained with seated patient is, on average, 53% bigger than the free area obtained with the patient lying down (confidence interval: 95%; p<0.001). Thus, adenoidal obstruction is larger when the examination is performed with the patient lying down.
Nasal videoendoscopy to evaluate adenoid hypertrophy with the patient lying down makes testing more reliable, better reproducing the patient's position when sleeping. Such accuracy is essential since it influences the decision for surgical intervention in this important and widespread disease in the pediatric population.
测量腺样体肥大在坐位和卧位时引起的气道阻塞情况，以寻找假设的差异。
48名年龄在2至12岁之间的儿童自发前往耳鼻喉科就诊，主诉打鼾和/或鼻塞。儿童性别不限，属于任何社会或种族群体。患者由同一名检查者进行坐位和卧位的鼻内镜检查。从每个患者每个鼻腔的两个体位获取鼻咽后部的图像。测量并比较两个体位下鼻咽的自由面积。图像分析由进行检查者以外的两名研究人员进行。
坐位患者的鼻咽自由面积平均比卧位患者的自由面积大53%（置信区间：95%；p<0.001）。因此，当患者卧位进行检查时，腺样体阻塞更大。
患者卧位时进行鼻内镜检查以评估腺样体肥大，使检查更可靠，能更好地重现患者睡眠时的体位。这种准确性至关重要，因为它会影响对儿科人群中这种重要且普遍的疾病进行手术干预的决策。
