Laryngeal cancer examinations are mainly divided into two categories. The first category is laryngoscopy, and the second is imaging studies. Laryngoscopy is further subdivided into fiberoptic laryngoscopy, electronic laryngoscopy, and indirect laryngoscopy. Indirect laryngoscopy is relatively rudimentary and generally doesn't play a significant role in diagnosing laryngeal cancer. Therefore, fiberoptic or electronic laryngoscopy is typically preferred as these methods can directly determine the presence of neoplasms in the throat. If a neoplasm is detected, further pathological biopsy testing can be considered. The other method is imaging studies, primarily involving CT scans or MRI of the throat. These are helpful in determining the size, extent, and preliminary nature of the throat neoplasms. Combined with the above methods, a definitive diagnosis can generally be established.
