What is stroboscopy?
Stroboscopy is a valuable diagnostic test that can be used to detect voice box problems. A trained otolaryngologist or speech pathologist can serve a painless test in less than half an out of an outpatient environment. The stroboscopic test includes the launch of a long, flexible tube on the neck that emits fast, bright light pulses. The frequency of the strok light is modified to correspond to the frequency of vocal cords, allowing the doctor to see a clear video image of the vocal cord activity. This procedure can detect problems such as cysts, tumors, especially tight or free cords and other abnormalities that would be difficult to recognize with less sophisticated types of tests.
The procedure of stroboscopy uses the well -known phenomenon of light and human vision to reproduce very fast, fine movements in the type of video with slow movement. The frequency frequency frequency is set near the normal vocal cord frequency in the production of a certain tone. As a patient vocalizes, Strobo illuminates chords of tightening, relaxationCI, climb and falling. The video source produced shows the average movement of the cord in a given time interval used by doctors to determine abnormalities in the movement or structure of the cord.
A person who has chronic sore throat, wheezing and speaking problems can be a candidate for stroboscopy if other diagnostic tests cannot detect the basic cause. During the initial evaluation, the doctor may explain in detail the procedure and make sure that the patient is comfortable with him. The stroboscopic test is a minimally invasive, very low risk and does not cause pain or discomfort for most individuals.
At the beginning of the procedure, the patient settles in a comfortable chair with his head tilted backwards. On the back of the tongue and neck, the local anesthetic is applied to prevent pain and gag. The stroboscope is carefully fed by the mouth and down the larynx to the place of vocal cords. The light light is on and the patient is instructed to make on their nThe organ was held by a long “e” sound. The frequency frequency is adjusted to match and the doctor begins the record process.
In most stroboscopic procedures, patients must undergo several laps of testing while making 'E' sounds on high, medium and low pitch. Some problems of voice boxes are not easily distinguished on certain playgrounds, so changing the pitch and testing can detect fine abnormality several times. Once the test is completed, the doctor and the patient can check the video immediately and evaluate the findings. Based on the results of stroboscopy, it is possible to decide on the need for surgical treatment, drugs or other tests.
