The hard nasal breathing in children may be caused by different reasons, and one of the most popular ones is the hypertrophy of the adenoid vegetations. The most common causes for this enlargement are the infection and the allergy. The recurrent acute infections in the beginning lead to transitional, and later to permanent growth of its sizes. The allergy is the other cause for the enlargement of the adenoid vegetation. The hard nasal breathing in children may be caused by other things: birth anomalies, distortion of the nasal septum, nasal foreign bodies, acute rinofaringitis, abscesses, tumors, etc.

Затрудненото носно дишане при децата може да се дължи на различни причини, като една от най-честите е хипертрофията на аденоидните вегетации. Най-чести причини за това увеличение са инфекцията и алергията. Рецидивиращите остри инфекции в началото водят до преходно, а след това и до постоянно увеличение на нейните размери. Алергията е другата главна причина за увеличението на аденоидната вегетация. Затрудненото носно дишане при децата може да се дължи и на други причини: вродени аномалии, изкривяване на носната преграда, чужди тела в носа, остри ринофарингити, абсцеси, тумори и др.
