What should be done for severe oral ulcers after head and neck radiation therapy?

Severe oral ulcers may occur after head and neck radiotherapy, requiring comprehensive management strategies: 1. Avoid hard or irritating foods to minimize stimulation of the ulcerated areas. 2. Consider topical application of traditional Chinese medicines such as Coptis (Huanglian) and Phellodendron (Huangbai) to clear heat, detoxify, promote tissue regeneration, and relieve pain. 3. Oral mucosal protectants, such as zinc-containing mouthwashes or oral patches, can reduce irritation and support healing. For severe pain, analgesics may be used as directed by a physician. 4. Nutritional support is also crucial; ensure intake of comprehensive and balanced nutrients to aid the body in repairing damaged tissues. 5. If ulcers persist or are accompanied by serious complications, seek medical attention promptly for professional treatment.
