The purpose of this study was to evaluate the position error of wearing a surgical mask during radiotherapy in head and neck cancer patients.Patients and Methods: We collected and analyzed 2351 kV X-ray image records of 81 patients with head and neck cancer who underwent image-guided radiotherapy (IGRT). Patients with/without a surgical mask were divided into the head-neck (HN) mask group and head-neck-shoulder (HNS) mask group. The position error in the X (left-right), Y (superior-inferior), Z (anterior-posterior), 3D (three dimensional) vectors, as well as the pitch and yaw axes were compared between the four groups.Results: We found that patients wearing surgical masks in the HN mask group showed no significant differences in the mean position error of the different types of headrest (p> 0.05). In the HNS mask group, only the type C headrest group showed significant differences (P < 0.05). The X axis values were − 0.05± 0.07 and − 0.11± 0.01 cm (P = 0.04), and the pitch axis values were 0.34± 0.29° and 0.83± 0.08° (P = 0.01).Conclusion: The mean position error of most patients wearing surgical masks was not greater than patients without a surgical mask. Patients wearing while receiving treatment is a low-cost and easy-to-implement prevention method.Keywords: COVID-19, head and neck cancer, image-guided radiotherapy, setup error
