For my 2nd revision 2 months ago my dr discovered a black hole. He took out my shifted L implant, replaced with alloderm to bridge and didnt want to use foreign materials becayse i had the hole and the e es high infection risk . He didnt fixed my perforation and avoided to touch the area. Is it dangerous to have a black hole? I function n breathe normally. I had ear/septum cartilage in my nose + L implant in the past and either of my previous nose jobs caused nasal perforation
