Background: Mucositis [bucal Mucous inflamation] is the most common complication resulting from the radiotherapy in tumors of head and neck. These malignancies are often curable through radiotherapy. This complication, however, may impair the treatment process and cause malnutrition. So far no medicine has been Known to prevent this complication. Vitamin E is a stabilizer of cell membrane and is also used in mucositis treatment. The survey of oral vitamin E effect on mucositis prophylaxis in radiotherapy of head and neck malignancies. Materials and Methods: Seventy patients afflicted with head and neck malignancies referring to Imam Khomeini Hospital were randomly divided into 2groups, two of whom died during treatment process. The first group (The case group consisting of 34 patients) Consumed oral vitamin E 200 mg daily for seven days. The second group (The control group) did not use any medicine at all. The two group underwent radiotherapy. They were compared and contrasted as to mucositis severity and dysphagia during treatment. Results: In the first group, since the fourth week up to the end of the treatment, there was a lower frequency and grade of mucositis in contrast with the control group. In the fourth week, the grade two mucositis in the first group (Case group) was 20.6% and 47.5% in the control group the difference was statistically significant (P=0.024). There was also a lower frequency and grade of dysphagia in the case group since the fourth week versus the control group. In the fourth week, moderate dysphagia was 29.4% in the case group and 55.9% in the control group. The difference was statistically significant (P=0.023). Conclusion: Oral vitamin E has Proved to be effective in the Prophylaxis of Moderate and severe mucositis and dysphagia resulting from radiotherapy.
