The ratio of adenoid thickness to nasopharyngeal cavity width of 0.78 belongs to pathological adenoid hypertrophy, which is more serious and can be controlled by timely treatment.
The ratio of adenoid thickness and nasopharyngeal cavity width, i.e., A/N value, is generally 0.5~0.6 for normal range, 0.61~0.7 for moderate adenoid hypertrophy, >0.7 for pathological hypertrophy, and >0.8 for significant hypertrophy.
An A/N value of 0.78 is pathological adenoid hypertrophy, but does not reach the level of significant hypertrophy, which is more serious. Untreated and unrelieved condition can lead to obstructive sleep apnea hypoventilation syndrome, adenoid facies, and nutritional dysplasia, etc. However, timely treatment with medications such as montelukast or surgical removal of adenoids can alleviate the condition.
Consultation with a specialist is recommended to choose the appropriate treatment for the condition, and medications need to be used under the guidance of a physician.
