Can laryngoscope detect laryngeal cancer?

Cancer experts introduce: Laryngoscopy for laryngeal cancer Cancer experts point out that laryngeal cancer is not terrible. As long as the disease is diagnosed early and treated in time, it is very likely to be controlled in time. Therefore, it is necessary to do a good job of laryngeal cancer examination to help people detect laryngeal cancer early. The following cancer experts from the Oncology Hospital introduce the post-examination of laryngeal cancer, hoping to help everyone.

1. Indirect laryngoscopy for laryngeal cancer: Anyone with hoarseness must undergo this examination to check the internal structure of the larynx, whether the two sides are symmetrical, whether there is redness, swelling, ulcers or tumors, and to check the activity of the vocal cords, fissured folds, epiglottis, etc. If necessary, under the clear vision of the indirect laryngoscope, take living tissue with forceps and send it for pathological examination or smear cytology examination.

2. Direct laryngoscopy for laryngeal cancer: usually only used when indirect laryngoscopy is unsatisfactory or it is difficult to obtain pathological specimens, such as the removal of living tissues from anterior commissure, laryngeal chamber or subglottic tumors, and the removal of polyps and papilloma. It is contraindicated for patients with cervical spine movement disorders and dyspnea. When direct laryngoscopy is necessary for combined laryngeal obstruction, preparations for tracheotomy should be made. Patients with hoarseness must undergo this examination to check the internal structure of the larynx, whether the two sides are symmetrical, whether there is redness, swelling, ulcers or tumors, and to check the movement of the vocal cords, fissured folds, epiglottis, etc. Some patients also need to take living tissues under the direct vision of the indirect laryngoscope for pathological examination or smear cytology examination.

3. Fiberoptic laryngoscopy and microlaryngoscopy for laryngeal cancer examination provide new diagnostic measures for laryngeal cancer examination and early detection. This examination includes fiberoptic laryngoscopy and microlaryngoscopy, which provides a new diagnostic method for early detection and diagnosis of some laryngeal cancer patients.

Laryngoscopy is one of the important means of diagnosing laryngeal cancer. It can observe the changes in the larynx and the activities of the vocal cords and epiglottis, find out whether the patient has local neoplasms, ulcers, etc., and observe the location, shape, and size of the tumor. It can also take living tissue for pathological examination. There are three types of laryngoscopy: direct laryngoscopy, indirect laryngoscopy, and fiberoptic laryngoscopy. Patients can choose different methods according to different diseases.
