congenital vocal cord dysplasia
Introduction
Introduction to congenital vocal cord dysplasia Newborns such as vocal cords are poorly developed or absent, and the throat chamber is active or over-represented instead of vocal cords. In the first few days after the child is born, there is no sound when crying. After the crying is dumb and thick, it is the sign of the throat room. Later, when the dysplastic vocal cords develop gradually, polyphonic or double sounds will occur, that is, the throat room will be issued. In the rough bass, there are often high-pitched sounds from the vocal cords. These two-tones often change but are irregular. 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.

Examine
Congenital vocal dysplasia check
Ear examination, hearing test.
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.
