hello and welcome to HCM,
It seems that you have a chronic ear problem which has gone to become
CHOLESTEATOMA and now you definitely need the surgery. These are a few things about this surgery if everything goes in a typical way:
1. The surgery is done within the ear and only a small scar may be seen that too very much behind the ear. Even this scar will disappear in a few months
2. Depending on th extent of the lesion the surgery may take around one to two hours for complete clearance of the disease and also to repair your ear bones
3. The surgery uses a plethora of instruments from microscopes to drilling machines
4. The average stay is around five days and rest with minimal activity is around one month
5. You will be advised to avoid head bath for three weeks
6, The cost varies from hospital to hospital while in government hospitals it is free. In private hospitals it may range from 15k to 70k and is covered by insurance
do not waste much time and get yourself operated soon as CHOLESTEATOMA is a potentially dangerous lesion
get well soon and have a safe recovery!!
