We have a lot of organs, and when different organs have problems, we use different tools to check for diseases. B ultrasound CT, gastroscopy and colonoscopy may be more common in clinic. But I do not know that the seemingly insignificant throat also has a professional examination, that is, we often say the laryngoscope, probably many people do not know about the laryngoscope, in fact, the laryngoscope is very useful.
When a person is hoarse, has a sore throat, holds his breath, or feels that he has swallowed a foreign object, the doctor will use some equipment to examine the throat and throat. At this time, the laryngoscope is needed. A flexible laryngoscope is a tube with a small video camera inserted into the throat to observe and record video. The image is displayed in an electronic computer and the results are obtained. In general, when there is a foreign body in the throat, swallowing difficulty or persistent throat pain, the doctor will cooperate with the laryngoscope for examination in order to find out the specific cause.
1. Indirect laryngoscopy
In the simplest form, doctors can use a small mirror stuck behind the throat and see the reflection of the light to determine the disease. The test takes only a few minutes to complete. During the examination, the patient will feel nausea and the doctor will apply anesthetic to the throat to desensitize the throat.
2. Fibrous laryngoscopy
Now common in hospitals, the test, also known as a flexible laryngoscopy, involves placing a small camera at the end of an optical fiber and threading the tube through the nose and throat. The procedure takes about 10 minutes and the doctor applies anesthetic to the throat and nose during the procedure. Sometimes decongestants are used to widen the nasal passages and reduce the discomfort, but some patients experience nausea and other reactions.
3. Direct laryngoscopy
This is a relatively complicated examination method. During the examination, the doctor will press the tongue under the laryngoscope and cover the cartilage flap of the organ through the machine. Then, through this operation, the tiny tumor or tissue in the throat can be cut for pathological examination. Direct laryngoscopy takes a long time, about 45 minutes, and requires general anesthesia to avoid pain and discomfort during the examination.
Laryngoscope may not be understood by many people, but it should be carried out according to the doctor's instructions when it is needed, and the precautions should be clearly known, such as preoperative relaxation, postoperative fasting and diet attention. These are needed to understand clearly, in order to prevent improper care, resulting in throat inflammation and infection and other problems.
