Laryngoscopy can examine the vocal cords and infer whether the recurrent laryngeal nerve is damaged through the movement of the vocal cords. It is recommended to go to the ENT department of the hospital in time and follow the doctor’s instructions to choose the appropriate examination method, in order to make a clear diagnosis as soon as possible and carry out the next step of treatment.
Laryngoscopy is a kind of endoscopic examination system, which can enter into the pharynx to observe the situation inside the laryngeal cavity, such as the color of the mucous membrane, the degree of smoothness, the presence of new organisms or foreign bodies, the movement of the laryngeal joints, the movement of the vocal cords and the closure of the larynx. If the activity of the vocal cords is normal bilaterally, it often suggests that the function of the recurrent laryngeal nerve is normal, but it is not possible to accurately assess the condition of the recurrent laryngeal nerve.
Currently there are many clinical laryngoscopy methods, the most commonly used are laryngeal electron endoscopy and fiberoptic laryngoscopy, both of which are able to observe the vocal cords and the recurrent laryngeal nerve, and at the same time can save the images. After laryngeal nerve paralysis, the movement of the vocal cords is often asymmetrical, and the movement of the vocal cords can be photographed through the laryngoscope to analyze the condition.
If you have laryngeal discomfort, or suspect laryngeal nerve disease, it is recommended to go to the hospital as soon as possible to the ear, nose and throat, follow the doctor’s instructions to complete the examination, after a clear diagnosis and standardized treatment, so as not to delay the condition.
