Soon after end of radiotherapy (1 of 4)
Early after conclusion of radiotherapy for a left anterior vocal cord cancer. There is a small amount of resolving radiation mucositis (white patches) in the interarytenoid area.

1 year later: slight post-radiation telangiectasia (2 of 4)
Nearly a year later, with mild vascular prominence, especially left vocal cord (right of image).

2 years later: post-radiation telangiectasia (3 of 4)
Now nearly two years after end of radiotherapy, much more prominent vascularity, called post-radiation telangiectasia. This side effect of radiation often begins to happen between one and two years after the end of radiotherapy. Notice that the post-radiation telangiectasias involve all areas that received radiation (including false vocal cords, etc.), and not just the area of original tumor. Voice remains very good.

3 years later: post-radiation telangiectasia (4 of 4)
Just over three years after the radiotherapy, telangiectasia now exuberant, but fairly stable. Voice remains very good.
