• Flat (or dome-shaped) tympanogram is type B curve of tympanogram which is seen in case of fluid in middle ear.
• Fluid (. pus) is seen in case of A50M and sterile non purulent effusion is seen in case of serous otitis mediA. So, in both these conditions flat tympanogram/type B tympanogram will be seen.
