Advantages and disadvantages of electronic laryngoscopy

We humans are a very complex creature, made up of many organs. When there is a problem in any part of our body, different symptoms will appear. When the throat is uncomfortable, the doctor will recommend us to do an electronic laryngoscopy. This examination can better understand the condition of the throat. Do we understand this? Let's learn about it below.

1. Indications

It is basically the same as direct laryngoscopy. Because the fiber laryngoscope has a soft and bendable body, strong brightness, and can be inserted through the nasal cavity for examination, it is particularly suitable for those who have difficulty in indirect laryngoscopy and direct laryngoscopy due to excessive sensitivity of the pharynx, trismus, difficulty opening the mouth, cervical vertebrae ankylosis, short neck, high tongue, short frenulum, epiglottis covering the laryngeal entrance, etc. Because the fiber laryngoscope can get close to the examination site and magnify it through the display, it can detect hidden lesions and early tiny lesions, and can perform local lesion biopsy and surgery on smaller vocal cord nodules and polyps. Equipped with a video recording system, the development of the lesion can be dynamically observed.

2. Contraindications

There are no clear absolute contraindications for fiberoptic laryngoscope. Relative contraindications may be given to patients with acute inflammation of the upper respiratory tract accompanied by dyspnea, severe heart and lung lesions, allergies to dicaine, and severe laryngeal obstruction of unknown cause.

3. Advantages

(1) The endoscope is thin, soft and bendable. The patient does not need to take a special position. The pain and trauma are minimal. It can be used to examine patients with neck deformities, difficulty opening the mouth, and weak or critically ill patients.

(2) It is easy to operate and is more conducive to examining various laryngeal lesions in a natural pronunciation state.

(3) The end of the endoscope tube is close to the anatomical part, which is especially effective for the examination of patients with short neck, thick tongue, narrow pharynx and infantile epiglottis.

4. Disadvantages

The mirror surface is small and the mirror tube is long, which produces a fisheye effect, the image is easily distorted, and the color fidelity is low

The above knowledge is about the advantages and disadvantages of electronic laryngoscopy. I hope the above knowledge can help everyone better understand this knowledge. None of us wants to be sick and we all hope to have a healthy body, so we should pay attention to health issues in our daily life. Only with a good body can we live and study better.
