Q: Can excessive treatment for nosebleeds permanently harm my nose?
Dr. Jason Hamilton, Director of Plastic and Reconstructive Surgery at Osborne Head and Neck Institute: It's possible to develop a septal perforation, which occurs when cartilage separating the two nostrils (known as the septum) develops a hole or fissure. This can cause a variety of symptoms, most notably nose bleeding. In HHT patients, septal perforation is usually attributed to nasal trauma from aggressive laser or electric coagulation sometimes used in treating epistaxis.
A septal perforation alters the anatomy of the nose, affecting its function. The normal humidity in the nose is decreased by constant airflow across the weak or torn edges of the perforation, causing the site of the perforation to dry out, leading to a crusted or scabbed area likely to bleed. When left untreated, it causes further deterioration of the condition.
The surgical procedure to repair a septal perforation should be performed soon after a diagnosis, and not as a last resort. The goal is to restore normal nasal anatomy and humidification and to reestablish the structural integrity of the nose – it is not a cure for HHT-related epistaxis.
