Question: Hi

info:
6 years old child
diagnosed with II-III grade adenoids a year ago
the repeated test yesterday showed: II-III grade adenoids
uses his mouth to breathe during the day
sleeps with the mouth a bit open
doesn't snore
Other health conditions: dermatitis, mild attention deficit disorder, delayed emotional/social delay, intellectually corresponds to his age

After being diagnosed the doctor prescribed:
Maresyl nasal spray: 1 puff twice per day for 5 days
Salt water spray: 2-3 puffs twice per day for 7 days
Flutinex nasal spray: 1 puff at night for one month - THIS IS A fluticasone based STEROID
Zirtec: 10 drops twice per day for 15 days
Tonsilotren: 1 pill 3 times per day for 1 month
Cinapsin: 1 pill 3 times per day for 1 month

Questions that I have:
Is the treatment prescribed by the doctor ok? Does it make sense?
Some medication is for tonsils and sinuses and I am confused why was it prescribed as they said the tonsils are not enlarged.
I am concerned also to use a steroid nasal spray for one month.
Will the treatment reduce the adenoids?
What would be a better approach? Should we do a sleep apnea test and see if the adenoids interfere with brain oxygenation and see if removing them surgically would be better?

thanks
