Why are septal perforations so difficult to repair?
A perforation or hole in the nasal septum is not just a one-layered hole. It is a hole in the cartilaginous and/or bony portion of the septum that separates your nose into two distinct sides, as well as a hole in both membranes that cover the septum. Unfortunately, we cannot just insert a cartilage graft, because the hole also extends into the covering membranes both on the right and the left sides of the septal cartilage. Therefore, when we repair the hole, we must repair three layers of hole: one membrane on one side, the cartilage in between and then the membrane on the other side.
