Welcome to HealthcareMagic forum.
The symptoms are typical presentation of serous otitis
media which needs to be addressed. As this is condition is caused by enlarged and inflamed adenoids
and tonsil, treating the causative factor is very essential to prevent future ear complications.
That being said, adenoids usually regress and disappear by 5 years of age in most children. Rarely when it persist, can cause recurring problems. Hence it is best for your son to undergo surgery.
There are plenty of children who are doing well post adenoidectomy
. So do not worry about the after effects of surgery. Your son hopefully will do well after the surgery too.
So go ahead with the treatment as planned.
Hope this answer is both helpful and informative.
