New imaging technique could transform precision of vocal fold injection procedures

Researchers at Stanford University, in collaboration with scientists at the German Cancer Institute, have shown for the first time that shortwave infrared (SWIR) imaging can be used to visualize injectable filler materials during injection laryngoplasty, a common procedure used to treat vocal fold paralysis and other forms of glottic insufficiency. The findings, published in Otolaryngology–Head and Neck Surgery, of this novel visualization technique could pave the way for precision-guided techniques in laryngeal surgery.
