(kōr-dot'ō-mē),
1. Any operation on the spinal cord.
2. Division of tracts of the spinal cord, which may be performed percutaneously (stereotactic cordotomy) or after laminectomy (open cordotomy) by various techniques such as incision or radiofrequency coagulation.
3. Incision through the membranous portion of the vocal fold to widen the posterior glottis in bilateral vocal paralysis.

An endoscopic visualization of the glottis and subglottis was sufficient in 4 patients of which 1 (20%) patient with bilateral vocal cord paralysis underwent endoscopic laser-assisted cordotomy with removal of interarytenoid adhesion and subglottic stenosis, 1 (20%) patient with subglottic stenosis with lax tracheal underwent endoscopic laser-assisted resection with placement of stent, 1 (20%) patient with stenosis at the level of tracheostoma underwent dilation using bougies, and one patient (20%) with subglottic stenosis at the level of C7-T1 and T1-T2 underwent excision of stenosis by holmium laser followed by dilatation of excised stenotic part by balloon followed by mitomycin C application around the excised region.
Postoperative improvement in phonation was seen in surgical resection anastomosis, laser-assisted cordotomy, laser-assisted excision with dilation with mitomycin C application, and laser excision with stenting as compared to flexible bronchoscopy with dilation alone.

Besides cordotomy, surgery within the brain or spinal cord to relieve pain includes severing connections at major junctions in pain pathways, such as at the places where pain fibers cross from one side of the cord to the other, or destroying parts of important relay stations in the brain like the thalamus, an egg-shaped cluster of nerve cells near the center of the brain.
