Hemangioma of the throat is a developmental malformation of the blood vessels, which may be due to the patient’s congenital malformation of the blood vessels. As the patient ages, the blood vessels continue to proliferate abnormally, resulting in a hemangioma. Overall, hemangiomas of the throat carry a certain degree of risk. When the throat hemangioma is small, the risk is relatively low and the patient may only have hoarseness, coughing, or blood in the sputum, which is generally not more dangerous. However, if the hemangioma increases in size, it may block the vocal fissure, which is the narrowest place for breathing, and an enlarged hemangioma blocking the passage may cause the patient to suffocate, and in severe cases, breathing difficulties may occur. In addition, if a hemangioma ruptures for unknown reasons, such as coughing or other forceful reasons, it may cause severe bleeding and a large amount of blood may enter the trachea and cause asphyxia. Therefore, if a patient is found to have a hemangioma of the throat, it is recommended to go to the hospital for a definite diagnosis and active treatment. Early detection can be done by supported laryngoscopic surgery or frozen removal. However, if it is a larger hemangioma, a tracheotomy may be required first, followed by surgical removal.
