Hi, first give her a course of antibiotic, a mucolytic
, steam inhalatin, paediatric nose drop ,valsalva
maneuvre, try this for 7-15 days.
IF still problem persists.
THEN first plan for tonsilloadenidectomy( if tonsils r also enlarged).
Again give her a course of above medicines for 15 days.
Then get a tympanometry
done, I m sure it will come out to be normal A type, means no surgery for glue ear.
