Hello there.
I can understand your concern.
How did you measure that there is only 20 percent capacity of hearing?
Kindly take him to a good ENT specialist near you.
You can search for ENT SPECIALISTS using this app itself. Or you can visit a good hospital near you and consult a ENT specialist there.
Whether operation will be needed or not is their call upon examining the child .
Best regards.
