The problem of water collecting behind the drum i.e. otitis media with effusion is very common in children and may go unnoticed sometimes. It follows any infection in upper respiratory passages. The treatment in the form of antibiotics and antiallergic and decongestants is given. In some cases it may take as long as 3 months for resolution to occur. If problem persists ( as shown by clinical finding, tympanogram and hearing test) beyond 3 months then surgery is advised.
