Ultrastructural Analysis of the Junctional Zone of Vocal Fold Polyps and Nodules
ثبت نشده
چکیده
Results: The junctional zone showed basement membrane thickening and the vessels showed endothelial interruptions. Some endothelial cells were degenerated and a few were apoptotic. Endothelial cells showed increased microfilaments with foci of detachment from the underlying basement membrane. Larger blood vessels showed large plump endothelial cells alternating with attenuated ones. There was also widening of the intercellular junctions between the endothelial cells.

متن کاملIs surgery necessary for all vocal fold polyps?
BACKGROUND Vocal fold polyps are benign nonneoplastic lesions thought to occur as a result of vocal abuse, misuse, or overuse. Similar to vocal fold nodules and cysts, these lesions result in significant disability, especially among those who require voice for their vocation. Current treatment includes conservative (i.e., nonsurgical) and surgical approaches. Most laryngologists agree that cons...
