The treatment of maxillofacial tumor is closely related to timely and early diagnosis. If early diagnosis is made, the tumor is confined and has not spread, it can be completely cured, but when patients are clinically found to be in the middle or late stage of tumor, the trauma of surgery increases, the difficulty of tumor treatment increases, the cost of treatment increases, the pain of patients increases and the cure rate decreases. Therefore, patients should be reminded that once abnormal growths and ulcers appear in the oral cavity, they should seek medical attention in time to determine the diagnosis, treatment plan and timely treatment through pathological examination. Oral and maxillofacial tumors are closely related to living habits, for example, this year I have diagnosed 5 cases of maxillofacial malignant tumors, among which 3 cases are already in advanced stage, these 3 cases are 3 male patients aged 66-75 years old, with long-term habits of drinking alcohol, smoking and hot diet, found oral swelling without timely medical attention, and only sought medical attention 2-4 months later, when the oral tumor was cauliflower-shaped and mouth opening was restricted, which delayed the treatment. Remind you to pay attention: compared with skin, oral mucosa is very thin, from the perspective of health care, the daily diet temperature should be controlled below 40 degrees, avoid too rough and irritating food, pay attention to oral hygiene, disease from the mouth, oral health care is really important.
