Whether adenoid surgery will recur is a concern for many parents. Will their child have the symptoms of adenoid hypertrophy that they once had, such as nasal congestion and snoring, again after the surgery. If the adenoidal hypertrophy surgery is completely removed, there is no recurrence. According to clinical studies in recent years, very few children will have symptoms of nasal congestion and snoring after adenoidal hypertrophy surgery. The most common reason for this symptom is that the child is allergic or has allergic reactions, which leads to nasal congestion and snoring again after adenoids surgery, and the so-called recurrence is mainly due to hyperplasia on top of the original adenoids.
