Summary

Background:

Hypertrophy of the adenoids is common in children. However, the anatomical site makes the adenoids difficult to assess, and studies evaluating the subject are ambiguous, especially with regard to the use of X-ray as an evaluation tool.

Objectives:

To compare medical history with clinical, radiological, and endoscopic evaluations of the adenoids and compare obstructed and non-obstructed children relative to the assessment methods.

Methods:

A prospective comparative study was conducted with children who were suspected of having enlarged adenoids. All parents completed a medical history questionnaire and patients underwent clinical evaluation based on Nasal Obstruction Index (NOI) scores, radiological assessment based on the lateral neck X-ray adenoid–nasopharynx (A/N( ratio, and endoscopic evaluation based on anatomical relations. Spearman correlations were used for comparison between methods.

Results:

We evaluated 36 patients, median age 5.33 years. Correlation measurements for clinical assessment and questionnaire (r = 0.582, P < 0.0001), questionnaire and endoscopy (r = 0.462, P = 0.005), and clinical assessment and nasal endoscopy (r = 0.621, P < 0.0001) were statistically significant. None of the parameters correlated with the radiological findings. A statistically significant difference was found between the obstructed and non-obstructed groups in both questionnaire (P = 0.004) and clinical assessment (P < 0.0001). However, no difference was found in X-ray measurements.

Conclusions: 

Lateral neck X-ray measurements were not correlated to symptoms, signs, or endoscopic findings. Therefore, medical professionals should use lateral neck radiography when considering adenoidectomy only on a highly selective basis.
