What to do about the hole in my nose?

Yes, this can be a debilitating condition both for breathing and appearance. If the perforation is not too large, it may be repaired surgically. Also, the bridge may be reconstructed with your own or donor rib cartilage. To help prevent further enlargement, it is imperative you practice proper nasal hygeine and would recommend seeing a specialist right away.

This is a common problem in cocaine users, as the cocaine can vasoconstrict, or squeeze the vessels that give blood to your septum, and the diminished blood flow can lead to cartilage and septum dying, leaving a big hole behind. Sometimes these create problems and sometimes they do not, but if it is enlarging I would seek help urgently. The bigger it gets, the more likely that it is that your external nose will collapse inward, as it loses structural support of the septum, and create what is called a saddle nose deformity. This can be very difficult to correct and requires advanced reconstructive techniques to fix both the septal perforation and the external appearance of the nose. The bigger it gets the harder the reconstruction will become. I agree with the others that you should avoid self-medicating at this point until you seek more help. Hope you're able to get help soon.

Thank you for your question.
Septal perforations do not always enlarge, but some do. If it is enlarging you need to see a board certified ENT/FPRS to examine the nose. A biopsy may be indicated. Septal perforation can be repaired after 1 year off cocaine. Also at the same time any external nasal shape deformity can be corrected. I hope this helps
