How Long Does Metaspray Take To Cure Adenoids?

Question: ot my son history with adenoid using metaspray from 9 days. His mouth breathing is continuing with sternum moves in at night during day time I hello good morning dr. Hope you got my sons history of adenoids.due to sternal in drawing at night along with accessory muscles prominently his sternum is little gone inside with very very little rib flare . I'm totally worried he getting some abnormality with his chest to look.during day time there is no sternum in draw during breath but it is gone little inside like funnel cheast starys.......... how long it will take to see the effect of metaspray and these abnormality will be self corrected once adrnoid swelling is gone with the spray?? Or we need to for surgery immediately to avoid deformity of chest orwe need to wait for metaspray effect for 1 or 2 months.will this weighting period cause his chest defotmity more.how to avoid or prevent until.

Thank u mam Is this sternal movements are only due to adenoids? X ray neck confirm adenoid. There will not be any lung or heart problems? need any test to rule out all. Mr pead dr and ENT DR is least bother about this when I asked to them. Your answer help us a lot.
