maxillary sinus cancer
Introduction
Introduction to maxillary sinus cancer Malignant tumors of the oral and maxillofacial regions are most common with cancer, and squamous cell carcinoma is the most common in cancer. In China, oral and maxillofacial squamous cell carcinoma often occurs between 40 and 60 years old, more men than women, with gingival cancer, tongue cancer, cheek cancer, sputum cancer and maxillary sinus cancer. Oral cancer is located in the north of the Yangtze River in China, accounting for 1.45-5.6% of systemic malignant tumors, 1.75-5.18 south of the Yangtze River, and more than 40% of all malignant tumors in India. The most common squamous cell carcinoma is squamous cell carcinoma. Because it is located in the maxillary sinus, it is asymptomatic at an early stage and is not easy to find. It is only noticed when the cancer develops to a certain extent and there are obvious symptoms. Because the early diagnosis of maxillary sinus cancer is often the key to the success of treatment, clinicians should be highly vigilant, and should be differentiated from periodontal disease, apical disease, and chronic maxillary sinusitis. basic knowledge The proportion of sickness: 0.0045% Susceptible people: no specific population Mode of infection: non-infectious Complications: cervical lymph node tuberculosis
Cause
Causes of maxillary sinus cancer
The etiology of oral cancer has not yet been fully understood, but the current consensus is that most oral cancers are related to environmental factors. Some external factors such as heat, chronic damage, ultraviolet rays, X-rays and other radioactive substances may become carcinogenic factors. In addition, internal factors such as neuropsychiatric factors, endocrine factors, immune status and genetic factors were found to be associated with the development of oral cancer.
Prevention
Maxillary sinus cancer prevention
The prevention of oral cancer is to reduce external stimuli and improve the body's disease resistance. Early treatment of maxillary sinus cancer is the key to achieving good therapeutic effect, but because of its late bone damage, it is sometimes diagnosed by clinical manifestations. It is difficult, so if the patient has symptoms of maxillary sinus disease, he should actively use various means to check to make the diagnosis as early as possible. If necessary, the maxillary sinus exploration operation can be performed for early detection and timely treatment.
Complication
Maxillary sinus cancer complications Complications, cervical lymph node tuberculosis
If the condition is prolonged for a long time, it can cause qi deficiency and blood stasis, and the poison gas will sink. The cancerous tumor will collapse, the malignant secretion will flow out, the fever will be cold, the taste will be tasteless, the whole body will be weak, and the lymph nodes will be transferred under the jaw.
Symptom
Maxillary sinus cancer symptoms Common symptoms Nasal lacrimal duct obstruction Osteoporosis Nasal soft palate Movement asymmetric opening Difficult diplopia
1. When it occurs on the inner wall of the maxillary sinus, there is nasal obstruction, nasal discharge, increased secretion from one side of the nasal cavity, and tearing in the obstruction of the nasolacrimal duct.
2. When it occurs on the upper wall of the maxillary sinus, there is an eyeball protruding and shifting upwards, which may cause double vision.
3. When it occurs on the outer wall of the maxillary sinus, it is characterized by swelling of the face and cheeks. After the skin is ruptured, the tumor is exposed, and the infraorbital nerve is involved, and the cheeks may feel dull or numb.
4. When it occurs on the back wall, it is difficult to open the mouth.
5. When it occurs in the lower wall, the teeth are loose, painful, swollen in the cheeks, or the wounds are not healed after the teeth fall off, and the tumors protrude.
6. There may be submandibular and cervical lymph node metastasis, sometimes transferred to the ear and the posterior pharyngeal lymph nodes.
Examine
Examination of maxillary sinus cancer
1. For clinical manifestations, the tumor is more limited than the ones to check the project to check the frame limit "A";
2. For the atypical clinical manifestations, the differential diagnosis is more difficult, and the larger the tumor is closely related to the surrounding important structure or the suspected metastatic examination project may include the check boxes "B" and "C".
Diagnosis
Diagnosis and diagnosis of maxillary sinus cancer
diagnosis
1. The maxillary part is inflated. According to the growth of the maxillary sinus, internal, or upper and lower growth, nasal symptoms, eye symptoms, cheek symptoms and loosening of the teeth may occur.
2. The cheeks feel dull or numb.
3. After the tooth is detached, it forms a ulcer that is not cured or has a tumor protruding.
4. X-ray film showed increased density of the maxillary sinus cavity, soft tissue mass and bone destruction of the sinus wall.
5. Histopathological examination confirmed the diagnosis.
Differential diagnosis
Diagnosis and identification of early sputum blood or adults with submandibular cervical lymph nodes and distant metastasis, etc., must be examined in detail, such as no tumor tissue in the nasal cavity, only see the nasal blood, the possibility of maxillary sinus cancer should be thought of, because Early diagnosis of maxillary sinus cancer is often the key to the success of treatment, so clinicians should be highly vigilant and should be differentiated from periodontal disease, apical disease, and chronic maxillary sinusitis.
