Abstract:
Myasthenia gravis is often difficult to diagnose and treat in older subjects due to complications, previous history and reciprocal interaction with drugs used to treat complications. An 84-year-old woman with slowly progressive 2-year dysphagia and dysarthria had reached critical condition with aspiration pneumonia. She was diagnosed with thymoma-free myasthenia gravis and her respirator removed after being administrated an anticholinesterase drug. Her dysphagia and dysarthria did not improve. Because of severe osteoporosis with two previous lumbar compression fractures and excessive thinness, she could not be given prednisolone or immunosuppressive drugs. Following cricopharyngeal myotomy and bilateral lateral palatopharyngeal wall narrowing, she could eat without misdeglutition and speak clearly.
