I have a roughly 5mm x3mm anterior perforation. So I have read several academic journals stating that perforated septum are hard to repair. Some of them detailing that the success rate of this procedure is anywhere between 40-60% due to the avascular nature of the cartilage. While other journals state that the success rate is quite high anywhere from 85% and up. My potential surgeon wants to operate on this perforation. What are the chances that this procedure will fail?
