Dear doctor, I hope that I can get your valuable consultancy in this regard : One of my school friends & relatives was suffering from ear discharge with bad smell in his school days incessantly. This had continued years together. After 8 years when he was studying college, he had undergone one operation called mastroidectomy for his problem. This was done after thorough examination of a senior ENT specialist & found that there was some infections developed inside the ear bone called mastroid & so he had removed this bone. Actually he didn't get any healing effect in this operation & throughout these 40 years he was suffering from the same ailments. We eagerly expect your valuable guidance through which he can get any relief from this chronic disease.
