When examining otalgia, it is important to pay attention not only to changes in and around the ear, but also to the nasal cavity, nasopharynx, sinuses, pharynx, mouth and head and neck. Regular checkups include a check of the quality of the Walkman, especially the sound quality and volume, and a personal hearing test. If symptoms such as dizziness, ear pain, tinnitus, and heavy hearing occur, promptly undergo an ear examination. Examination items for otalgia: 1. Bacterial culture of ear, nose and throat swabs: Bacteria in the ear, nose and throat come from outside and are not pathogenic under normal circumstances. However, infection can occur when the body’s systemic or local resistance decreases and other external factors lead to disease. Therefore, bacterial culture of ear, nose and throat swabs can isolate pathogenic bacteria and help in the diagnosis of otitis media, rhinitis, sinusitis, diphtheria, purulent tonsillitis, acute pharyngitis, etc. The specimen is taken by the doctor using a sterile cotton swab and the secretion from the patient’s lesion site is sent for examination. 2.CT examination of otorhinolaryngology: It is a method to examine the otorhinolaryngology through CT. The patient unloads the examination contraindicated items on his body as required, lies on the instrument at the request of the doctor, undergoes the examination, and finds the pathological features after deriving the image. In the case of middle ear mastoiditis, especially when combined with cholesteatoma and bone destruction, the scope and extent can be clarified to provide surgical options.
