What can laryngoscopy detect? Is laryngoscopy painful

Laryngoscopy is a more commonly used otolaryngology examination, the most important thing is to screen for cancer, such as laryngeal cancer, nasopharyngeal cancer, hypopharyngeal cancer, etc., which can be detected by laryngoscopy. Laryngoscopy can also detect whether there are vocal cord nodules, vocal cord polyps, vocal cord leukoplakia and other throat diseases. Therefore, laryngoscopy is a more commonly used examination method for patients with throat lesions.

After the examination, some patients can clarify the condition, and some patients need to combine other auxiliary examinations to make a clear diagnosis, and then carry out follow-up**.

Precautions for laryngoscopy.

1. Laryngoscopy can be divided into many types, some are direct laryngoscopes, some are indirect laryngoscopes, and some are electronic fiber laryngoscopes. Ordinary laryngoscopy mainly refers to electronic fiber laryngoscope, before electronic fiber laryngoscopy, you can eat less food, not necessarily fasting, but be careful not to eat too much, there will be no nausea and vomiting during the examination.

2. In addition, laryngoscopy should be done according to the patient's age and physical condition, if the heart can not bear it, it is recommended not to do laryngoscopy for the time being. In addition, if you have a laryngoscopy, if your throat is very numb, be careful not to drink water or eat immediately, as your throat is very numb, which will affect swallowing and cause choking. Therefore, it will take some time to complete the laryngoscopy, and wait for the effect of the anesthetic to subside before eating and drinking.

There are two types of laryngoscopy: indirect laryngoscopy and direct laryngoscopy. The two have different ways of use and scope of application. Indirect laryngoscopy is the most commonly used in laryngeal examination, and the diameter of the mirror can be selected according to the patient's pharyngeal cavity, and its gentle rotation allows the entire larynx to be examined on a region-by-area basis.

Indirect laryngoscopy is simple and easy to master for the physician and less painful for the patient, but it should not be used in patients with sensitive gag reflex and patients with hypertrophy of the base of the tongue and poor epiglottic lift.

Direct laryngoscopy is not a routine examination of the larynx, as it is traumatic to the patient to varying degrees. Direct laryngoscopy is indicated when indirect laryngoscopy and fiberoptic laryngoscopy are unsuccessful to take a tissue biopsy specimen from the larynx. Direct laryngoscopy can be applied to laryngeal lesions, such as electrocautery, benign tumor resection, topical medication, and removal of foreign bodies in the larynx, and can also be used for bronchoscopy, endotracheal anesthesia, endotracheal intubation, etc.

Laryngoscopy can check for infectious diseases in the pharynx, larynx, trachea and other parts, such as acute pharyngitis, tonsillitis, tracheitis, chronic pharyngitis, etc., and can also detect possible space-occupying lesions in the throat such as tumors, polyps, vocal cord nodules, etc., and can also detect foreign bodies in the throat. Laryngoscopy is mainly divided into indirect laryngoscope, direct laryngoscope, fiber laryngoscope, etc., because the throat of the human body is deep, it is difficult to find the deep lesions through inspection, so laryngoscopy has an irreplaceable role in examining the possible lesions of the throat.

Laryngoscopy is generally done from the nasal cavity to the nasopharynx to the hypopharynx. It can be detected for nasal related diseases, such as nasal hemangioma, nasal septum deviation, nasal polyps, etc.; Nasopharyngeal related diseases, such as adenoidal hypertrophy, nasopharyngeal carcinoma, etc.; Hypopharyngeal-related diseases such as epiglottis cysts, vocal cord nodules, vocal cord polyps, hypopharyngeal cancer. Glottic or subglottic-related disorders, such as laryngeal cancer, may also be detected.

Fiberoptic laryngoscopy or video laryngoscopy can examine the details of the throat mucosa to rule out vocal cord disorders, epiglottis cysts, or pharyngitis. Due to the length of the mirror, it is not possible to continue to look down into the lower respiratory tract. The condition of the lower respiratory tract cannot be observed, and bronchoscopy must be separately examined to observe the lower respiratory tract.

Details such as trachea, bronchi, and lungs.

Laryngoscopy is used to determine whether there is inflammation, lesions, tumors or cancers in the throat, and it can also detect the patient's throat discomfort in time.

Laryngoscopy is a specialized examination of the ear, nose and throat, which is mainly used to screen for cancer, such as laryngeal cancer, nasopharyngeal cancer, hypopharyngeal cancer, etc. In laryngoscopy, laryngoscopy can be performed on the throat for diseases such as vocal cord nodules, vocal cord polyps, and vocal cord leukoplakia.

Fiber laryngoscopy can be examined through the nasal cavity, which can find diseases of the nasal cavity, such as whether there is a deviated septum, adenoid hypertrophy, and nasopharyngeal cancer, and can also check the throat, including whether there are foreign bodies, whether there is inflammation, whether there are benign diseases such as vocal cord polyps and epiglottis cysts, as well as malignant diseases such as laryngeal cancer and hypopharyngeal cancer. Common types of laryngoscopes include indirect laryngoscopes, video laryngoscopes, strobe laryngoscopes, and fiber laryngoscopes. Fiberoptic laryngoscopy is the most common examination in the hospital, and there is a foreign body sensation in the pharynx, sore throat, and hoarseness.

Laryngoscopy can determine whether there are any diseases such as laryngitis, vocal cord nodules, polyps, etc., and laryngoscopy can also detect early laryngeal cancer. Laryngoscopy is divided into indirect laryngoscopy, direct laryngoscope, fiber laryngoscope, electronic laryngoscope, and dynamic laryngoscope. Indirect laryngoscopy is simple and easy to perform, and the patient is less painful.

Direct laryngoscopy is an invasive procedure that is generally intolerable to patients with mucosal surface anesthesia. Fiberoptic laryngoscopy is easy to operate and is more conducive to the examination of various laryngeal lesions in a natural articulation state. The advantage of a video laryngoscope is that it is easy to operate.

Laryngoscopy may reveal the following diseases: congenital diseases of the larynx, laryngeal trauma and laryngeal foreign bodies, acute inflammation of the larynx such as acute epiglottitis, acute laryngitis, and laryngeal perichondritis. Chronic non-specific laryngeal inflammation such as chronic laryngitis, laryngeal polyps, vocal cord nodules.

Laryngeal nerve dysfunction and functional disorders such as laryngospasm.

Problem analysis: laryngoscopy can detect many diseases, mainly laryngitis, vocal cord abnormalities, and other tumors, etc., which are generally examined under the guidance of doctors.

Suggestions: It is recommended that you do not be in a hurry, such examinations are generally examined under the guidance of a doctor, and you will be allowed to go to the hospital for examination when necessary.

Laryngoscopy is divided into indirect laryngoscopy, direct examination, as well as electronic laryngoscopy and fiberoptic laryngoscope. Diseases of the throat can be detected by electronic laryngoscopy, and the most important thing is to screen for cancer, such as laryngeal cancer, nasopharyngeal cancer, and hypopharyngeal cancer.

Laryngoscopy can detect some diseases of the throat, such as laryngeal cancer, and sometimes fish bones can also be removed through laryngoscope.

Laryngoscopy is one of the most commonly used examination tools in otolaryngology, and different laryngoscopic examination areas are different, the most common ones are indirect laryngoscopy, dynamic laryngoscopy, electronic laryngoscope, and fiber laryngoscope.

Indirect laryngoscopy is used to examine lesions within the throat. Chronic pharyngitis is considered to be present when inflammatory changes in the throat wall are found, regardless of whether there are chronic symptoms. Hyperthyroidism requires T3, T4, TSH, and ultrasonography of the neck.

There are still many diseases that can be detected by laryngoscopy, mainly laryngitis, abnormalities of the vocal cords, and the occurrence of other tumors

Laryngoscope is currently used in clinical practice to detect and assist the pharynx, commonly used to detect foreign bodies, inflammation, white spots and new organisms in the upper end of the pharynx, larynx, trachea and esophagus. The diagnosis of laryngeal cancer by laryngoscopy is to find abnormal laryngeal abnormalities and take a sample biopsy, and the pathology report is the gold standard for the diagnosis of laryngeal cancer.

Laryngoscopy is divided into indirect laryngoscopy, direct examination and electronic laryngoscope, fiber laryngoscope, there are many kinds of laryngoscope, we usually say that the general laryngoscope refers to the electronic laryngoscopy, now commonly used is electronic laryngoscopy, electronic laryngoscopy can detect what diseases? That is, diseases of the throat can be detected through electronic laryngoscopy, and the most important thing is to screen for cancer, such as laryngeal cancer, nasopharyngeal cancer, and hypopharyngeal cancer, which can be detected by laryngoscopy.

According to the location and principle of chest X-ray, it is mainly through the observation of morphological changes in the lungs and heart to diagnose related diseases, such as heart diseases will be manifested on chest X-ray, and more lung diseases, such as tuberculosis, pneumonia, pleural effusion and other diseases.

Laryngoscopy is generally used to check for diseases of the throat or vocal cords, such as retching and sore throat.

Laryngoscopy is still painful for most patients, and direct laryngoscopy can easily cause nausea and vomiting, so the operation must be performed on an empty stomach, that is, stop eating and drinking 4 to 6 hours before the examination.

Patients with severe systemic diseases and very weak constitution may consider postponing surgery. If you have high blood pressure or have a serious heart condition and you need to have a check-up, you should work with your physician to prepare for surgery.

Hello, laryngoscopy is generally **, but most patients will have nausea symptoms, so it is recommended not to eat a few hours before the laryngoscopy.

At the beginning, the doctor gave you an indirect laryngoscopy, that is, the kind with a small mirror at the front of a tube, which must be cooperated, it will be a little nauseous, and you can't eat or drink when you do laryngoscopy, or you won't be nauseated. There is also a video laryngoscope, which is a thin tube that goes through your nose and makes sure your nose is clean before doing it. This kind of very uncomfortable, don't move, otherwise it will hurt you during the examination, endure it for a while, at most a few minutes, endure it, but the child may not cooperate, you must not let him pull out the tube, otherwise, it will hurt the throat or nasal cavity.

Lidocaine can be applied locally before laryngoscopy, and few patients report distress. Fiberoptic laryngoscopy or electronic laryngoscopy is currently the most widely used examination and method in clinical practice. The laryngoscope can directly observe most of the nasal cavity, nasopharynx, oropharynx, hypopharynx, larynx and trachea, and pathological biopsy can be performed if there is a space-occupying disease; If there is a pharyngeal foreign body, it can be removed; Small vocal cord polyps can be removed; If there is a cricoarytenoid dislocation, it can be reduced by dialing.

The endoscopic narrow band technique can be used to show the distribution of local mucosa and blood vessels, and abnormal neovascularization can indicate whether there are early malignant pathological tissue changes in the locality, which provides a reference for the early diagnosis of malignant tumors.

The video laryngoscope is not painful. First spray anesthetic, then the nasal tube, it will take three to five minutes, and it will be over in a minute or two. Generally, doctors in county-level hospitals can do it.

I just finished it the day before yesterday, and the laryngoscope is not painful. I was a doctor in a second-class hospital, and I would use an iron-like thing from my mouth into my throat, and my tongue would stick out, and I would cooperate with the doctor to say one by one, so I didn't need to be particularly nervous or painful, and then the doctor would slowly probe in. I was not very good at doing it for the first time, and then I used anesthetic medicine for half an hour, and the whole tongue was numb and unconscious, and the first time I did it, it was very easy to do, and I pulled my tongue and cooperated with the doctor to say one by one, and then I did it directly....

You can choose to do an electronic nasopharyngoscope, **bitter, I was examined in the General Hospital of the Armed Police yesterday, the equipment in the local hospital may be relatively poor, and those laryngoscopes or something may be disgusting.

It depends on the individual situation and the hospital. When I did it, the anesthetic was not ready, so it was a little painful, but it was bearable.

Just finished the video laryngoscopy, and it was not painful at all.

Question 1: What symptoms do you need to do laryngoscopy If you don't believe in laryngoscopy, there is only a biopsy, but the biopsy is to check whether there are lesions. I'm saying that your symptoms are like laryngitis.

Don't doubt anymore and concentrate on healing. If you feel a foreign body or a tightness that is caused by inflammation, the throat is red and swollen, and the lymphatic follicles in the throat are hyperplasia, don't worry, it's not a big deal. Increase psychological pressure on yourself in vain.

- I wish you good health. Question 2: When do I need laryngoscopy? You can do a laryngoscope to see it intuitively, this is the best diagnostic method.

Throat cancer syndrome generally has bleeding manifestations, you should be chronic pharyngitis, you can take some Chinese medicine to recuperate, such as Banxia magnolia soup, and the diet should be light.

Question 3: Under what circumstances do laryngoscopy need to be done? This is generally not clear with indirect laryngoscopy, or surgery is required, or indirect laryngoscope is used in some cases where pathology needs to be taken.

Question 4: Under what circumstances do laryngoscopy be done? Due to the deep location of the larynx and the complex physiological structure, it cannot be directly seen, so some special examination methods are required for laryngeal examination, such as indirect laryngoscopy, direct laryngoscopy, fiber laryngoscope, electronic laryngoscope, strobe laryngoscope, ultra-high-speed cinematography, sonography or glottography.

Question 5: When is laryngoscopy done? Something is stuck in the throat.

Question 6: Under what circumstances do laryngoscopy be done? The laryngoscope does not hurt the throat, and the anesthetic is sprayed into the nose and mouth at the beginning.

It's a little uncomfortable and stuffy when I do it [because it's coming in through the nose].

To do laryngoscopy is to look at the pharynx, epiglottis, ventricular girdle, larynxal ventricle, piriform fossa, ......

Mostly the vocal cords, of course.

If you always use your voice inappropriately.

It may be a nodule of the vocal cords, severe failure to close the vocal cords, hoarseness.

Of course, it is also possible to have pharyngitis.

If the situation is serious or you value your throat a lot, you can do it with a missing one.

I studied vocal music, and I was once fooled by a doctor into making one.

Because I'm applying a peace of mind.

As for you, consider it at your discretion.

Because hoarseness and fatigue are common, it is usually chronic pharyngitis or vocal cord nodules.

But in any case, let your mother stop yelling every day.

This is the key to the debate [to silence].
