After a child’s cold has cleared up, two small white spots are found on the tonsils, accompanied by nasal congestion and mouth breathing during naps. An ear, nose, and throat examination confirms adenoid hypertrophy and rhinitis. Treatment with ceftriaxone and azithromycin oral solution, along with ambroxol oral solution, has been ineffective, and the white spots persist. It is recommended to undergo a detailed examination in the hospital’s internal medicine department, including bacterial secretion culture, for targeted medication. Adenoid hypertrophy may significantly affect a child’s health, and it is advised to seek a specialist consultation for professional treatment. Meanwhile, parents should pay attention to their child’s diet and daily life to aid in their early recovery.
