Children's adenoid hypertrophy has a variety of symptoms, mainly including the following aspects. First: It may lead to nasal congestion, accompanied by runny nose and nasal speech due to obstructive nasal sounds and other clinical manifestations. Second: It may cause the child to develop secretory otitis media or purulent otitis media, resulting in ear pain and hearing loss among other clinical manifestations. Third: Due to the long-term hypertrophy of adenoid tissue affecting ventilation, it may cause children to breathe through the mouth. Prolonged mouth breathing may result in a condition known as adenoid facies. Fourth: Some systemic symptoms may occur, such as slowed growth and development, cognitive impairments, irritability, drowsiness, teeth grinding, easy awakening, lack of concentration, and bedwetting among other symptoms.
