Today (8/21) I saw an ENT. He confirmed that the eardrum was 100% healed and looked like it was actually never injured. He said he questioned whether it was perforated in the first place, but I showed him photos I took and he then agreed that it was previously perforated.
He does not know much (if anything) about diving and when I queried him about whether I could dive again, he said yes, but you should know that since this happened once, you are now more susceptible to it occurring again in the future. He explained that the eardrum tissue is made up of three layers and two of the three layers heal after a perforation, but the third does not, which makes me more susceptible.
He did say, however, that because the perforation was so tiny and healed so quickly, it made it less likely it would occur again (solely from the standpoint it occurring again due to a previous perf).
I asked him when I could dive again and he didn't really know. He said "it's 100% healed, but I would still wait another month or two before diving again."
I am thankful I got good news, but I wish I would have been able to see an ENT with dive experience and knowledge.
I'm confused that it's 100% back to normal, but I should still wait another month or two. I am fine with that, but if it's 100% back to normal, what's the purpose in waiting? In other words, if there's still healing or strengthening that will take place, it isn't 100% yet, right?
