Ethmoid sinus malignancy

Introduction to ethmoid sinus malignancy The incidence of ethmoid sinus tumors is second only to the maxillary sinus, ranking second, with squamous cell carcinoma and adenocarcinoma, as well as sarcoma and malignant melanoma. Due to the small size of the ethmoid sinus, the bone wall of the sieve chamber is very thin, and it is closely connected with the eyelid and the anterior skull base, and sometimes the bone plate is congenital defect. Therefore, the ethmoid sinus tumor is more likely to spread, and the ethmoid sinus malignant tumor is difficult to find early, and the tumor enlargement involves When the surrounding tissue, clinical symptoms appear, such as damage to the eyelids into the eyelids, may appear exophthalmos, eye movement disorders, diplopia and visual impairment; invading the sieve plate or dura mater, the patient shows increased headache; tumor to the nasal cavity or other The development of the sinus can cause sinus congestion, bloody sputum and olfactory dysfunction of the sinus; the outward development of the tumor can cause the sacral roots to bulge, the malignant tumor originating from the ethmoid sinus, and may coexist with other sinus cancer in the late stage. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: cerebrospinal fluid rhinorrhea meningitis brain abscess

Cause of ethmoid sinus malignancy

1. Squamous cell carcinoma, also known as skin-like carcinoma, begins with skin covered with squamous epithelium. The rim of the skin and the junction of the conjunctiva is its multiple sites. The severity of this type of cancer is higher than that of basal cell carcinoma. The development is faster and the damage is greater.

2. Adenocarcinoma is a malignant tumor of the parotid epithelium with different structures, but no residual pleomorphic adenoma. Adenocarcinoma accounts for 9% of parotid epithelial tumors and belongs to a higher degree of malignancy in parotid malignant tumors.

Sinus sinus malignancy prevention

There is no effective preventive measure for this disease. Early diagnosis and early treatment are the key to the prevention and treatment of this disease.

Sinus sinus malignant tumor complications Complications, cerebrospinal fluid, meningitis, meningitis, brain abscess

Complications after craniofacial combined approach, mainly wound infection, bleeding, cerebrospinal fluid rhinorrhea or leakage, and meningitis, brain abscess.

Symptoms of ethmoid sinus malignancy common symptoms visual impairment diplopia dysosmia

Clinically, it is difficult to identify which sinus the tumor originated from. X-ray or CT examination can confirm the tumor range and the presence or absence of intracranial metastasis, but the biologic examination is still needed to determine the tumor nature.

Examination of ethmoid sinus malignancies

X-ray or CT examination can determine the extent of the tumor and the presence or absence of intracranial metastases, but the nature of the tumor is still required for biopsy.

Diagnosis and differentiation of ethmoid sinus malignant tumor

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

Different from other sinus tumors.
