Purpose: evaluate 1) reliability and accuracy of cone-beam computed tomography (CBCT) for assessing adenoid size compared to nasoendoscopy (NE), 2) Influence of clinical experience on CBCT diagnosis.
Methods: Four blinded evaluators reviewed randomized CBCT images. Adenoid size was graded on a 4-point scale for CBCT and NE (by an pediatric otolaryngologist). Reliability was assessed with intra and inter-observer agreement. Accuracy was assessed with agreement between CBCT and NE, plus sensitivity / specificity analysis.
Results: 39 consecutively assessed, non-syndromic subjects (11.5 ± 2.8 years) were evaluated. CBCT demonstrated excellent sensitivity (88%) and specificity (93%), strong accuracy (ICC = 0.80, 95% CI ± 0.15), and very good reliability, both within observers (ICC = 0.85, 95% CI ± 0.08) and between observers (ICC = 0.84 ± 0.08). Clinical experience of the CBCT evaluators did not have a statistically significant effect.
Conclusions: CBCT is a reliable and accurate tool for identifying adenoid hypertrophy.
