The Importance of Fiberoptic Laryngoscopy

Introduction

Fiberoptic laryngoscopy is a minimally invasive technique used to examine the nasopharynx and throat. Use a soft, flexible fiberoptic laryngoscope to enter the larynx through the nasal cavity or mouth. Because it is equipped with a high-resolution camera and lighting system, it can transmit images of the larynx to the monitor in real time, allowing the doctor to clearly observe the shape of the larynx. , structure and activity, is one of the important means to evaluate the health of the larynx.

Applicability of fiberoptic laryngoscopy

1.Hoarseness or vocal problems.

2.Persistent throat pain or foreign body sensation.

3.Suspected laryngeal tumors, polyps or other abnormalities.

4.Remove foreign bodies in the throat.

5.Evaluation before and after laryngeal surgery and thyroid surgery.

6.Used for regular inspections of professional voice users (such as singers and teachers).

Check process

Fiberoptic laryngoscopy is usually performed under local anesthesia to reduce discomfort. The patient only needs to lie relaxedly on the examination bed, and the doctor inserts the fiberoptic laryngoscope through the nasal cavity or mouth and gradually enters the larynx. The entire procedure usually only takes a few minutes, and the patient may feel a slight foreign body sensation, but there is usually no obvious pain.

Preparation before inspection

Patients often need to fast for several hours before fiberoptic laryngoscopy to avoid vomiting and aspiration. A local anesthetic spray or lozenge may also be used to reduce discomfort. The patient will be asked to sit or lie down on the examination chair and relax.

Advantages of fiberoptic laryngoscopy

1.Minimally invasive: The thin and soft design of the fiber laryngoscope reduces the stimulation and damage to the laryngeal tissue.

2.Accuracy: High-definition images allow doctors to accurately diagnose throat problems.

3.Fast and convenient: The examination process is relatively short, the patient recovers quickly and does not affect normal life.

Security and Risk

Fiberoptic laryngoscopy is a relatively safe operation, but there may still be some risks, such as nose bleeding, throat irritation, etc. However, these risks are usually small and can be minimized by an experienced physician.

Things to note after inspection

1.If the patient is under topical anesthesia, fast for 1-2 hours after the examination to avoid choking or aspiration.

2.There may be temporary throat discomfort after the examination, which can be relieved by swallowing saliva or drinking water for patients without anesthesia.

3.Avoid coughing violently and blowing your nose forcefully to avoid bleeding.

4.Follow the doctor’s recommendations for follow-up treatment or follow-up.

Conclusion

Fiber laryngoscopy provides an important basis for the diagnosis and treatment of laryngeal diseases. It is a safe and effective examination method. Only by keeping abreast of throat health and detecting problems early can we better protect our voices and respiratory systems. Take care of your throat health and let clear voice accompany your life!
