The glands located in our nasopharyngeal area are immune tissues. Enlargement of these glands can lead to an increase in their size, which may block our posterior nasal apertures. Consequently, the secretions in our nasal cavity cannot be properly discharged. This may eventually lead to spontaneous infections causing sinusitis, characterized by the discharge of yellow nasal mucus. Thus, there is a direct relationship between the occurrence of sinusitis in children and the enlargement of these glands. Clinically, it can be observed that after surgery for gland enlargement, the symptoms of sinusitis and the discharge of yellow nasal mucus are significantly reduced or even completely cured. Therefore, it can be said that there is a direct relationship between gland enlargement and conditions such as rhinitis, sinusitis, and the discharge of yellow nasal mucus.
