Background: Management of a case of chronic non-healing ulcer with ozone therapy. Case Presentation: A 50 years old patient, an operated case of Squamous Cell Carcinoma buccal mucos undergone segmental mandibular resection with jaw reconstruction and free fibular flap. Post-operatively he developed chronic non-healing ulcer at the site of old tooth extraction. He was managed at our centre with Ozone therapy. He responded miraculously and recovered completely in 5 days. Now, after 11 months he is asymptomatic and his flap has been matured completely. Conclusion: Post-Surgical non-healing ulcers inside mouth are very common. In this particular case we used ozone gas for killing the pathogenic organism inside the sinus and for healing of non-healing ulcer and patient respond miraculously. With this case we assume that ozone gargling can be used to sanitize oral mucosa quite effectively and it can be used in this current Covid -19 pandemic also.
