Female 79 yrs old

Laryngeal dystonia, adductor type, in 2021 transoral bilateral laser myoneurectomy of the thyro-arytenoid muscle, with satisfying effect on her voice. There was no need for Btx-injections. Over the past year, she started to complain about increasing vocal strain, and therefore she was very much motivated for a redo.

Interesting detail of the first surgery: I preserved the medial part of the TA muscle... . Probably this strip of muscle and the likely fact of reinnervation could be the reason for recurrence of the dystonia.
