Nowadays, malignant tumors can be said to be everywhere in the world. Ear, nose and throat are no exception, and tumors can be found in these areas. The incidence rate of ear tumors is low, about 8.7% of otorhinolaryngologic tumors. The clinical manifestations of ear tumors lack specificity and need to be combined with imaging examinations. For example, CT of temporal bone shows a moderately dense soft tissue mass with a fan-shaped change at the edge of the tympanic capsule, with uniform density and moderate enhancement on enhancement scan. MRI of temporal bone shows solid, lobulated, equal signal in T1, equal or slightly high signal in T2, and significant enhancement in enhancement scan. However, pathological examination is the standard to confirm the diagnosis. Nasopharyngeal cancer accounts for 12.4~27.9% of systemic malignant tumors and 60% of otorhinolaryngological malignant tumors. Indirect nasopharyngoscopy can detect the primary site of cancer at an early stage, which can be nodular, cauliflower-like or ulcerative, showing mucosal congestion, rough erosion and nasopharyngeal sidewall bulge. 2.Exfoliative cytological examination: the nasopharynx can be scraped or the secretion can be attracted by negative pressure and smear to check the cancer cells, and the positive rate can reach 70-90%. 3.Biopsy: Take biopsies from nasopharynx for pathological examination, if the biopsy is negative, those who are clinically suspicious should be biopsied several times. If the primary focus is unknown and there are suspicious enlarged lymph nodes in the neck, lymph node puncture or biopsy is feasible. 4.X-ray radiography or CT scan examination: thickening of soft tissue shadow or bone destruction in the nasopharynx can be seen. 5.Serological examination: the positive rate of nasopharyngeal carcinoma diagnosis can reach 84% with the increase of EBV antibody titer in serum or EBV immunofluorescence antibody assay. 6.Nasopharyngeal fluorescein staining examination: stained with acridine orange and observed under fluorescent microscope. The incidence of laryngeal cancer accounts for about 1-5% of the whole body tumors, and the preferred age is 50-70 years old. The etiology of laryngeal cancer is unknown and may be related to excessive long-term stimulation by smoking, alcohol and harmful chemical gases. Any male over 40 years old with hoarseness, which has not been treated for more than 3 weeks, should have a careful examination of the larynx. In case of the above positive findings on indirect or direct laryngoscopy, a biopsy should be performed to clarify the diagnosis. It can also be used to take off cells from the larynx with a rolled cotton or brush to check the cancer cells. Frontal and lateral X-ray and CT tomography of larynx can understand the location and scope of cancer.
