Adenoid blockage of 50% of 9-year-old children belongs to the second degree of hypertrophy, if there is open mouth breathing, snoring and other more serious, need to be treated promptly; if there is no obvious symptoms is not very serious.
Adenoids proliferate vigorously during childhood from 2 to 6 years of age, and gradually shrink after 10 years of age. Adenoid hypertrophy occurs in children with repeated episodes of inflammation of the adenoids and surrounding areas. Enlarged adenoids that block one-half of the posterior nostril are considered to be second-degree hypertrophy.
If the blockage is not accompanied by symptoms such as snoring and open-mouth breathing, the airway is relatively open, and the adenoids may shrink with age and relieve the condition, so it is not very serious and can be treated with montelukast, mometasone furoate nasal spray, and so on.
If the blockage is accompanied by the above symptoms, or even with otitis media, sinusitis, etc., it suggests that there is a more serious blockage of the airway, and untimely treatment may lead to adenoidal facies, unresponsiveness, etc. Often, surgical removal of the adenoids is performed on the basis of the above mentioned medications.
Specific conditions should consult a specialist in time to choose the appropriate treatment according to the condition.
