I assume you have otosclerosis in the left ear. Me too! However instead of a stapedectomy I had a stapedotomy in 2011 (they drill little hole and put in little device vs, replacing stapes). My hearing improved immediately and has remained stable with only typical hearing loss with age. I had no issues after surgery.
What does your doctor/surgeon say about this? We are not many that have this type of problem and surgery.
Here is an interesting article.
