Abstract |
A 36-year-old woman presented an inability to ingestion and mild hemiparesis with superficial and deep sensory disturbances on the left side for two months after a stroke. Dysphagia was originated from bilateral cricopharyngeal spasm, which was disclosed by videofluorography, manometry at the pharyngo-esophageal segment, and needle electromyography. Although no focal lesion of the brain was detected even with MRI, neurological and electrophysiological findings suggested that the lesion was localized to the lower pontine and mudullary tegmentum on the right side. Two months after the onset, botulinum toxin (10 units) was administered into the bilateral cricopharyngeal muscles, which resulted in restoration of the normal swallowing function in 5 days, and the normal function is lasting 5 years. Botulinum toxin therapy is non-invasive and effective for cricopharyngeal spasm. This non-invasive method will be the first choice for cricopharyngeal spasm replacing surgical intervention.
