Hi Sir,
I have gone through your query. There can me many causes for hearing loss. Thus it is difficult to answer this question till your detail history and some investigation are done. At your age it may be chronic suppurative otitis media if your ear is discharging and progressive hearing loss.

But to rule out other diseases and to reach the near diagnosis you may go for
1.Otoscopic examination of ear.
2. Pure tone audiometry and
3. Impedance audiometry if your ear is non discharging.

Just send me the investigation finding or detail history for better answering of your query.

Thanks
