What diseases can laryngoscope detect?

Now because of the discomfort in the throat, I go to the hospital for relevant examinations. This examination is called a laryngoscope, which is inserted directly into the throat. Through the detection of the laryngoscope, the human organs can be observed. The laryngoscope examination can determine whether the human throat has inflammation, lesions, tumors or cancer. At the same time, it can also detect in time what problem is causing the throat discomfort in the patient.

When patients visit the doctor because of throat discomfort, generally, the otolaryngologist can roughly diagnose the disease and provide treatment by asking about the medical history and performing indirect laryngoscopy in the outpatient clinic.

For some patients, due to various reasons, doctors need to perform relevant laryngoscopy to make a clear diagnosis. The more commonly used laryngoscopy examinations in clinical practice include rigid tube laryngoscope, fiberoptic (or electronic) laryngoscope and microlaryngoscope.

The more common reasons, such as the patient's high arched tongue dorsum, overly sensitive pharyngeal reflex, and inability to lift the epiglottis, lead to the inability to clearly see the laryngeal cavity and laryngopharynx under indirect laryngoscopy. At this time, most of the time, a rigid tube laryngoscope is needed for examination. First, spray the oropharynx with a surface anesthetic (dicaine) to weaken the pharyngeal reflex, then place a straight hard tube on the tongue in the mouth, and the various structures of the throat can be clearly seen on the monitor. The inspection results can be saved or printed out as photos. This is a non-invasive test and very few patients may experience anesthesia allergy. You can eat normally 2 hours after the examination, when the anesthetic effect has completely worn off.

For some patients, the laryngeal area cannot be fully exposed even with a rigid laryngoscope, or the patient cannot open his mouth. In this case, a fiber laryngoscope or fiber electronic laryngoscope examination is required. Because it is a fiber hose, the laryngeal cavity and laryngopharynx, as well as the nasal cavity, nasopharynx and trachea can be clearly seen. Anesthesia also uses dicaine. In addition to spraying it on the pharynx, dicaine is dripped into the laryngeal cavity. This is the most widely used non-invasive examination in laryngology. Except for a very small number of patients with high fever, difficulty breathing, etc., there are almost no contraindications.

After the above-mentioned laryngoscopy, if lesions are found in the larynx or laryngopharynx, especially lumps and ulcers of unknown cause, a biopsy under a microlaryngoscopy is required to clarify their nature. Generally, general anesthesia is used, the larynx is exposed by direct laryngoscopy, a support frame is used, and the operation is performed under a binocular microscope. Some patients experience pharyngeal mucosal damage after surgery, which will heal after a few days.
