Sinus hypertrophy laser, i.e., turbinate hypertrophy treated by laser irradiation, and nasal bleeding for one month in a row is not a normal phenomenon, and should be considered whether there is inflammation of the surgical wound or mucosal damage, etc.. Usually after this treatment, a small amount of nasal bleeding may occur, which is a normal physiological phenomenon caused by the surgical wound not completely healed. However, if bleeding occurs for a month in a row, it indicates that there is a definite bleeding point in the nasal cavity and it has not been treated effectively. Continuous bleeding may also be caused if the laser irradiated area is damaged and not healed after this treatment, and if there is inflammation. After laser surgery for sinus hypertrophy, you need to clean and protect the surgical wounds, and go to the hospital regularly for nasal cavity review.
