Here, we report long-term results of this procedure. Surgical outcome was evaluated using patient surveys and perceptual voice assessment.

متن کاملBrainstem pathology in spasmodic dysphonia.
Spasmodic dysphonia (SD) is a primary focal dystonia of unknown pathophysiology, characterized by involuntary spasms in the laryngeal muscles during speech production. We examined two rare cases of postmortem brainstem tissue from SD patients compared to four controls. In the SD patients, small clusters of inflammation were found in the reticular formation surrounding solitary tract, spinal tri...
