my son at 3 yrs old had to have his adinoids and tonsils removed due to one fact that he had sleep apnea and would stop breathing for 5 seconds. mind you he sleep all day!!!! sounding like a whale in the ocean. it did benifit him no problems now just that he's exceptionally small for his age, but i blame the "lack" of oxegen to his brain for the first 3 yrs. didnt seem like he was growing at all.....hope this help's you.
