Surgery

A number of operations that cut one of the nerves of the vocal folds (the recurrent laryngeal nerve) has improved the voice of many for several months to several years but the improvement may be temporary.

An operation called “selective laryngeal adductor denervation-rennervation (SLAD-R)” is effective specifically for adductor spasmodic dysphonia which has shown good outcomes in about 80% of people at 4 years. Post-surgery voices can be imperfect and about 15% of people have significant difficulties.If symptoms do recur this is typically in the first 12 months. Another operation called “recurrent laryngeal nerve avulsion” has positive outcomes of 80% at three years.
