Flexible optical fiber technology can improve laser surgery for voice box tumors

MedicalXpress | 四月 08, 2026

Worcester Polytechnic Institute (WPI) researchers have developed a flexible optical fiber that can be threaded through a medical endoscope and steered into the larynx to destroy hard-to-reach tumors on the vocal folds, an advance that could expand outpatient laser treatment options for patients whose only other choice might be surgery under general anesthesia. The team's work is published in the Journal of Medical Devices.
