A 10-and-a-half-year-old girl, 133cm tall and weighing 40 kg, appears slightly overweight, and has a habit of mouth breathing. However, she can also breathe through her nose without obstruction, although it’s not very smooth, and she can hear a noticeable breathing sound when she is quiet. She has consulted a local doctor who suggested that the surgical outcome might not be very good but also mentioned that there might be some effect. Now, she wants to ask experts whether the child has been diagnosed with adenoid hypertrophy and whether surgery is necessary? (Detailed examination results attached).
