Re: Anyone ruptured an eardrum?
Healing time will depend on the size and location of the perforation. Your eardrum is skin, so it is always growing and will heal if there are not complicating factors. For now, keep it dry. Dont let any water get in it. ENTs are sometimes split on whether they use antibiotic drops for a "dry" ie not infected perforation. If the cause of the rupture was infection, you have to clear up the infection first, but they generally heal well. There is not a lot of hearing loss from these if your hearing was good initially. This is only a mechanical loss until the drum heals. A barotrauma rupture (scuba, overpressure from flash bang, external blow, etc) can also cause neurological hearing loss, which has nothing to do with whether or not your eardrum heals back properly. Judging by some of your history, you likely have some of this already from your time in the "patch".
As it is healing, your ENT will probably tell you to avoid any changes in barometric pressure, up or down in altitude. The important thing is the change, not really which direction it is. While the hole is there, its no big deal, but once it is healed but fragile, you can have some problems. Air is not really a big deal, because the relative changes in pressure across the drum are still small. We keep our divers with ruptured TMs out for quite a while because the pressure changes in water are significantly greater, plus the temperature differences with a perforation under water can cause some nasty problems.
Keep it dry until the ENT says otherwise. They will check your hearing, and tell you if it should heal well based on how it looks. The last one I had hurt for about 2 weeks.
Good luck
