Chen Xiaohong, ENT, Peking Tongren Hospital: According to the preliminary description, it can be judged that this is a sinus occupation, and the possibility of malignancy is high. The final confirmation must rely on tissue biopsy. Suggested pathology biopsy, if the mass is highly malignant, advocate the first radiotherapy, and then assessed at 50gy, according to the tumor’s degree of sensitivity to radiotherapy, to take different therapeutic measures: very sensitive to continue radical amount of radiotherapy; if not sensitive, wait a month after the surgical treatment. If it is a low-grade malignancy, in combination with the patient’s age, the surgical approach can be flexible: if the surgical extent of the tumor is completely in the endoscopic field of view and the risk is controllable, endoscopic surgery can be performed, with intraoperative delivery of safe margins and all the preparations for an intermediate open surgery; otherwise a nasolateral incision should be taken, or a total or partial resection of the maxilla, with postoperative radiotherapy. An MRI showed a mass in the sinus, but no mass in the orbit. Now it has been on anti-inflammatory drugs for a few days, the left eye is not swollen, just slightly smaller than the right eye, if there are no other symptoms, just protruding eyeballs could it be malignant?
