ABSTRACT
INTRODUCTION:
The goals of this study were to evaluate (1) the reliability and accuracy of cone-beam computed tomography (CBCT) for assessing adenoid size compared with nasoendoscopy and (2) the influence of clinical experience on CBCT diagnosis.METHODS:
Adenoid size was graded on a 4-point scale for CBCT and nasoendoscopy by a pediatric otolaryngologist. Reliability was assessed with intraobserver and interobserver agreement. Accuracy was assessed with agreement between CBCT and nasoendoscopy, plus sensitivity and specificity analyses. The CBCT assessments were completed by a team of 4 evaluators an oral and maxillofacial radiologist, an airway orthodontist who participates in the multidisciplinary team, an academic orthodontist whose primary research is in 3-dimensional imaging, and a highly experienced private practice orthodontist comfortable with CBCT imaging. Each evaluator was specifically chosen to represent a unique set of clinical and radiographic experiences. All evaluators were blinded to the subject's identity and clinical history, and they evaluated the images in a unique random order and evaluated each image 3 times separated by a minimum of 7 days. The same computer hardware and software were used.RESULTS:
Thirty-nine consecutively assessed, nonsyndromic subjects (ages, 11.5 ± 2.8 years) were evaluated. The CBCT demonstrated excellent sensitivity (88%) and specificity (93%), strong accuracy (ICC, 0.80; 95% CI, ± 0.15), and good reliability, both within observers (ICC, 0.85; 95% CI, ± 0.08) and between observers (ICC, 0.84; 95% CI, ± 0.08). The clinical experience of the CBCT evaluator did not have a statistically significant effect.CONCLUSIONS:
CBCT is a reliable and accurate tool for identifying adenoid hypertrophy.
