I have spasmodic dysphonia, just had a botox injection and& my voice is v.Good now. Would my vocal cords now look normal in a larynoscopy?

No. Botox paralyzes muscles so if you look at your vocal cords now, they will not appear normal. They will not be moving normally. Spasmodic dysphonia means that your cords were too contracted. Now they will be lax. What is important is that you sound better, not what your cords look like.
Yes. Botox would not change the way something looks on a scope. But with attempting an action it could change the amount of movement that you try to achieve. I am glad the Botox helped.
