Although the answer depends upon the type and extent of the cancer (for example, skin vs. nasal cavity) and the dosage of radiation delivered, most surgeons would discourage performing an elective cosmetic procedure on freshly-irradiated nasal tissue. Radiation can harm the nasal tissue's ability to heal and permanently impacts the nasal cartilagenous support structure, lymphatics, and incites some scarring within the nasal soft tissues. This means that the risk of poor aesthetic outcome, infection, and other complications such as a septal perforation and chronic nasal dysfunction is elevated compared to non-irradiated noses. Despite these obvious risks, this does not entirely preclude your ability to have aesthetic surgery, especially if there is another medical indication for a nasal surgical procedure (i.e. correction of a septal deviation). A widely accepted, but mostly untested standard in the surgical field is to wait 10 years following irradiation prior to contemplating elective cosmetic surgery. Clearly, this pre-determined amount of time depends heavily on your condition and radiation dose received, as well as the degree of comfort of your surgeon in performing the surgery. However, although some surgeons might agree that rhinoplasty could potentially be performed safely within the 10 year window; most surgeons would also agree that nasal procedures that rely heavily on placing artificial nasal implants or large structural cartilage grafts (such as rib cartilage grafts) are contraindicated in irradiated noses. My recommendation to you would be to complete the therapy and achieve cancer remission or cure (5 years) and then sit down with your surgeon to discuss the surgical options for addressing your nasal cosmetic concerns. Best of luck!
