Abstract: Nasopharyngeal tonsil commonly called “Adenoids”. "Adenoid" meaning "glandular", "gland-like", or "lymphatic". Hypertrophy of the lymphoid tissues in the throat (the adenoids) is the most common cause of nasal obstruction in children. The mouth is always open because upper airway congestion/narrowing has made patients obligatory mouth breathers. Persistent mouth breathing seen in children due to nasal obstruction can lead to malocclusion. The most common symptoms are habitual mouth breathing and snoring. The most dangerous symptom is sleep apnea due to obstruction. Homoeopathic medicines treat them effectively. These remedies aim to control the infection and inflammation in the initial phase and eliminate the risk of reoccurrence by improving the immunity in the later phase.
