Three common clinical examination methods for laryngeal cancer

Clinically, the examination of laryngeal cancer is mainly carried out in the throat, which provides an important basis for the correct treatment of laryngeal cancer and is very necessary for laryngeal cancer patients. What are the common examination methods for laryngeal cancer ? The following will tell you about the common examination methods for laryngeal cancer.

In general, the common examination methods for laryngeal cancer are:

1. Laryngoscopy: This method of laryngeal cancer examination can observe changes in the larynx and the activities of the vocal cords, epiglottis, etc. It can detect whether there are neoplasms, ulcers, etc. in the local area. There are direct laryngoscopes, indirect laryngoscopes and fiber laryngoscopes. It can also observe the location, shape and size of the tumor, and can take living tissue for pathological examination. Therefore, laryngoscopy is an important means of diagnosing laryngeal cancer. Ulcers, etc., can also observe the location, shape and size of the tumor. If it is a pyriform sinus cancer, it can be seen that the pyriform sinus on both sides is asymmetrical, there is cauliflower-like cancer tissue in the pyriform sinus on the affected side, and there is saliva retention or food residue accumulation; posterior cricoid cartilage cancer is not easy to detect in the early stage, and cancerous lesions in the cricoid cartilage plate can be seen in the late stage. If there are ulcers or granulation tissue on the surface, it is mostly laryngopharyngeal posterior wall cancer. Living tissue can also be taken for pathological examination through fiber laryngoscope.

2. Biopsy: This can confirm laryngeal cancer. If multiple biopsies are negative, a laryngoscope is used to take a biopsy for pathological examination. If laryngeal cancer cannot be ruled out, a laryngeal fissure biopsy can be performed.

3. CT scan and X-ray examination: It can assist laryngoscopy, lateral X-ray plain film, and anteroposterior tomography. It can clarify the location, size, range, shape, and cartilage involvement of the tumor. CT scan can further observe whether the laryngeal space and epiglottic cartilage are invaded by the tumor, and provide the scope and location for surgery. This is also a common examination method for laryngeal cancer.

The above is an introduction to the common laryngeal cancer examination methods. I believe everyone has some understanding of this. Once you have laryngeal cancer, you must go to the hospital for treatment immediately to avoid causing greater harm to the patient.
