Palatal perforation is usually caused by congenital factors or tumors and other factors, and can be seen in nasal malignant granuloma and pharyngeal tuberculosis. The general condition is fair, with weak sweating, poor appetite, often with low fever, a few with high fever, and ineffective treatment with general antibiotics. Local examination shows swelling, erosion and even ulceration of the nasal mucosa, which is granulomatous and has a grayish-white necrotic surface. Most of them involve the inferior turbinate or nasal septum first, and in obvious cases, it can lead to swelling and bulging of the external part of the nose. So what tests do we need to do?
1.CT examination of otorhinolaryngology CT examination of otorhinolaryngology is a method of examining the otorhinolaryngology by CT. For middle ear mastoiditis, especially when combined with cholesteatoma and bone destruction, the scope and degree can be clarified to provide surgical plan. It can clarify the morphology, size, scope, invasion and metastasis of adjacent organs of benign and malignant tumors, and can make qualitative diagnosis of certain tumors. It can be used for the review of tumor to observe the treatment effect and recurrence. . CT is the preferred examination method for laryngeal injury and can identify hematoma and edema; it can also observe the injury after radiotherapy – necrosis, fibrosis and atrophy, cavity narrowing. CT helps to confirm the diagnosis of congenital diseases of the ear, especially congenital malformations of the middle and inner ear. Patients are asked to remove any contraindicated items from their body for the examination, lie down on the instrument at the doctor’s request, undergo the examination, and look for pathological features after the images are produced. It is suitable for: congenital diseases of the ear; inflammatory diseases of the ear, nose and throat; tumors of the ear, nose and throat; and injuries of the ear, nose and throat.
2.General radiography General radiography can take cranial films, chest films, abdominal plain films, and bone and joint films of the limbs. It has the following advantages compared with fluoroscopy: the image of the examined area is permanently preserved on the film, which can be used for analysis, discussion and review for comparison. It can be preserved as scientific research data. Radiographs can show microscopic structures, such as early sources of disease above 2mm, which are clearer than fluoroscopy. Radiographs can examine thicker parts of the body and allow the patient to receive a smaller amount of X-rays. Fluoroscopy can observe lung, pleura, mediastinum and heart, large vessel lesions, skeletal fractures and joint dislocations of the extremities. It can be used for the diagnosis of soft tissues of the extremities, the esophagus and radiopaque foreign bodies of the gastrointestinal tract. Abdominal plain films can be used to understand the presence of pneumoperitoneum after gastrointestinal perforation and the presence of intestinal obstruction.
