Cilia, the motile protrusions that protrude from the surface of some eukaryotic cells due to abnormal cilia structure and function, lead to poor cilia motility and clearance dysfunction, which can cause recurrent sinusitis, bronchitis, pneumonia, otitis media, ectopic pregnancy, infertility and hydrocephalus. Tests related to cilia clearance dysfunction: Bronchial dilatation, sinusitis and visceral displacement can be diagnosed based on chest X-ray, bronchogram, sinus X-ray and CT scan. Nasal and bronchial mucosal biopsies with cilia abnormalities seen under electron microscopy can give a positive diagnosis. CT examination of the chest: CT examination of the chest is a method of examining the chest by x-ray computed tomography (CT). Chest wall examination can detect asbestosis with pleural thickening that cannot be shown on chest X-ray. When pleural effusion is found, if small pleural nodules or masses are found, it can help the diagnosis of metastases and mesothelioma. According to the CT value of pleural masses, encapsulated effusion, limited mesothelioma and extra pleural lipoma can be identified. With the help of CT enhancement, chest wall hemangioma can be diagnosed, and rib fracture and rib destruction can be well shown. Lung biopsy: Lung biopsy is a percutaneous lung biopsy. It is used for the diagnosis and differential diagnosis of peripheral lung lesions or diffuse lung lesions. General radiographs: General radiographs can be taken for cranial films, chest films, abdominal plain films, and bone and joint films of the extremities. Bronchography: Bronchography is an examination method for direct observation of bronchial lesions with good diagnostic effect, but with some pain for patients. Bronchography is one of the important examination methods for chest diseases and has a definite diagnostic value for bronchial diseases. It can determine the location and extent of lesions and the nature of lesions, and provide the basis for clinical selection of effective treatment. Congenital or acquired bronchial and lung disorders, such as bronchial dilatation, bronchial and lung tumors, mechanized pneumonia, chronic lung abscess, and pulmonary atelectasis.
