Anytime you have a sudden hearing loss it should be bumped up to an emergency visit to see an ENT, any doctor that doesn’t refer you to one is guilty of malpractice IMO! I know several people who have permanent holes in their eardrums and it has left them with either a mixed loss or just a conductive loss. A conductive loss is easier to get to more or less normal hearing with a HA as long as you can amplify it high enough, a mixed loss depending on how severe the SSHL is, a HA can help but it won’t bring your hearing back to what it was prior to the sudden hearing loss. The hole in your eardrum could of been caused by a number of things: loud noise too close to the ear, rapid change in pressure such as in flying or scuba diving, foreign object in the ear (q tip), slap to the side of the head, etc. Small holes normally heal in a couple months, larger ones take longer and some never heal and have to be surgically repaired by doing a tympanoplasty which grafts your own tissue over the hole or a myringoplasty where they surgically put a gel or special kind of paper over the hole. if you don’t get it fixed you have to use earplugs when taking a shower or swimming to keep water from entering your middle ear. Leaving it open makes you more susceptible to future ear infections, mastoiditis and vertigo. The HA that is best for you is the HA that you like and allows you to hear the best, since everyone hears differently what is the best for one person could be less than perfect for another person, only you will be able to answer which is best for you. Good luck!
