Clinicians have questioned the value of lateral soft tissue neck x-ray (LSTN) in assessing adenoid size. Elaborate cephalometric assays have been devised to measure degree of nasopharyngeal obstruction secondary to adenoid hypertrophy. This study prospectively studied 73 children, aged 11 months to 13 years, with clinical evidence of adenoid hypertrophy to assess how well a LSTN correlates with direct intraoperative observation of adenoid size and nasopharyngeal obstruction. We found a relatively weak correlation (Pearson coefficient r = 0.34) between x-ray and operative observations. We conclude that LSTN is an appropriate examination in the preoperative assessment of children being considered for adenoidectomy. However, this test must be interpreted by recognizing the inherent limitations of evaluating a dynamic structure, such as the nasopharynx, through a non-dynamic modality.
临床医生对颈部软组织侧位X线片（LSTN）在评估腺样体大小方面的价值提出了质疑。人们已经设计出精细的头影测量分析法来测量腺样体肥大导致的鼻咽部阻塞程度。本研究对73名年龄在11个月至13岁之间、有腺样体肥大临床证据的儿童进行了前瞻性研究，以评估LSTN与术中直接观察腺样体大小及鼻咽部阻塞情况的相关性。我们发现X线片与手术观察结果之间的相关性相对较弱（皮尔逊系数r = 0.34）。我们得出结论，LSTN是对考虑行腺样体切除术的儿童进行术前评估的一项合适检查。然而，在解释这项检查结果时，必须认识到通过非动态方式评估动态结构（如鼻咽部）所固有的局限性。
