Insights
Cone-beam computed tomography (CBCT) accurately diagnoses adenoid hypertrophy in children. This imaging technique is a reliable alternative to nasopharyngoscopy (NE), especially for children who cannot tolerate the procedure.
Area of Science:
- Medical Imaging
- Pediatric Otolaryngology
- Diagnostic Accuracy
Background:
- Adenoid hypertrophy is a common cause of pediatric sleep-disordered breathing.
- Accurate diagnosis is crucial for effective treatment planning.
- Nasopharyngoscopy (NE) is a standard diagnostic tool, but can be challenging in children.
Purpose of the Study:
- To assess the reliability and accuracy of cone-beam computed tomography (CBCT) for diagnosing adenoid hypertrophy in Chinese children.
- To evaluate the clinical utility of CBCT as a diagnostic alternative.
Main Methods:
- A retrospective study of 300 children with sleep snoring was conducted.
- All participants underwent both nasopharyngoscopy (NE) and CBCT.
- Diagnostic performance metrics (sensitivity, specificity, PPV, NPV, likelihood ratios) of CBCT were compared against NE criteria.
Main Results:
- CBCT demonstrated high diagnostic accuracy for adenoid hypertrophy.
- Key performance indicators included: sensitivity 87.3%, specificity 89.2%, positive predictive value 93.20%, and negative predictive value 80.5%.
- A Kappa value of .748 indicated good agreement between CBCT and NE.
Conclusions:
- Cone-beam computed tomography (CBCT) is a reliable and accurate imaging modality for diagnosing adenoid hypertrophy in pediatric patients.
- CBCT serves as a valuable alternative to nasopharyngoscopy, particularly for children with contraindications or intolerance to NE.
Objective:
The main objectives of the study were to investigate the reliability and accuracy of cone-beam computed tomography (CBCT) in the diagnosis of adenoid hypertrophy in Chinese children and to evaluate its value in clinical diagnosis.
Methods:
From January 2019 to January 2020, 300 children with sleep snoring in Xinhua Hospital Affiliated to Medical College of Shanghai Jiaotong University were retrospectively studied. All patients underwent nasopharyngoscopy (NE) and CBCT scanning. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of CBCT were determined according to the diagnostic criteria of NE, and the consistency between CBCT and NE was evaluated.
Results:
The clinical study of 300 children patients found that compared with NE, CBCT had a sensitivity of 87.3%, specificity of 89.2%, the positive predictive value of 93.20%, the negative predictive value of 80.5%, the positive likelihood ratio of 8.08, the negative likelihood ratio of 0.14, and Kappa value of .748.
Conclusion:
CBCT is a reliable and accurate tool for the diagnosis of adenoid hypertrophy and can be used as an alternative examination method for children with contraindications or intolerance during NE.
Level Of Evidence:
