Is irrigation the best option?

Okay so long story short I do not have access to a lot of my medical records as a child, however I do have very small ear canals and know as a child I had to get tubes in my ears and commonly had ear infection issues.

Currently, I believe my left ear is impacted with wax and I wanted to flush it out at home. However, I am very scared there is a hole in my ear that would cause an issue with irrigation. How can I know for sure? Would I see an ENT for something like this? Or is it rarer than I think it would be? Just wanted to see if anyone has had similar experience.
