Most children have congenital throat sounds and are prone to breathing difficulties. Under the anesthesia, the infant-type front combined mirror will be irritated. It can be seen that the two throat chambers are close to each other, the vocal cords are not visible, and the larynx is removed at the tip of the mirror. See vocal cord hypoplasia, asymmetry or Absently absent, some vocal cords seem normal, but adduction and abduction are bad.

Laryngoscopy

Laryngoscope A device or device used to examine a laryngeal lesion. It can be divided into an indirect laryngoscope, a direct laryngoscope, a dynamic laryngoscope, a fiber laryngoscope, a circular laryscope with a handle for indirect laryngoscopy, and the principle of specular reflection. , lighting and observing the throat and throat. The direct laryngoscope is a hollow metal or plastic tube with a lighting device at the end that directly illuminates and observes the throat. The dynamic laryngoscope is based on the illumination light of the discharge tube as the light source. The period, amplitude and phase changes of the vocal cord vibration are observed by the indirect laryngoscope. It is also possible to understand the difference of the vibration of the vocal cords on both sides that cannot be found by other laryngoscopes, which is helpful for diagnosis. The fiber laryngoscope uses the flexibility of the light-transmissive glass fiber to make a fine and soft laryngoscope of the lens body. It can find small lesions such as the laryngeal surface and the subglottic area, especially for neck deformity, difficulty in opening the mouth, and years. Old and frail patients.
