Laryngeal cancer is a malignant tumor of the larynx, and the clinical treatment is mainly surgical, including radiation therapy, chemotherapy, and comprehensive treatment. Whether one can speak after surgery depends on the method of the surgery. Total laryngectomy renders the patient unable to speak. We can help the patient speak through esophageal speech, electronic larynx, and other assistive devices, but there is a significant difference in the sound quality and volume compared to normal speech. With partial laryngectomy, depending on the specific situation, the patient may be able to speak, but the quality of speech still differs greatly from normal speech. Overall, it depends on the condition of the laryngeal cancer and the surgical approach.
