Summary
A new Modified Adenoid Grading System (MAGS) offers a reliable method for assessing adenoid size using nasal endoscopy. This validated system improves quantitative evaluation for children with chronic mouth breathing.
Area of Science:
- Otolaryngology
- Pediatric Medicine
- Medical Imaging
Background:
- Nasal endoscopy is optimal for evaluating adenoid size.
- Quantitative endoscopic assessment of adenoid size remains understudied.
Purpose of the Study:
- To propose and validate a Modified Adenoid Grading System (MAGS).
- To compare MAGS with existing endoscopic scoring methods for adenoid size.
Main Methods:
- Prospective study involving children with chronic mouth breathing undergoing nasal endoscopy.
- Evaluation of digital endoscopic images using traditional methods and MAGS.
- Intraoperative nasal endoscopy assessment of adenoid size in patients undergoing adenoidectomy.
Main Results:
- MAGS demonstrated high inter-rater reliability (Kappa = 0.869).
- MAGS significantly correlated with nasopharyngeal obstruction (Spearman's r = 0.796) and choanal obstruction (Spearman's r = 0.816).
Conclusions:
- The MAGS is a reliable and valid tool for assessing adenoid size.
- MAGS may be a more suitable grading system for endoscopic adenoid evaluation.
