Abstract
- Myasthenia gravis (MG), which is the most common autoimmune neuromuscular junction disorder, is characterized by weakness of musdes and increased fatigability after repetitive use, and recovery after rest. The diagnosis is based on a detailed history, physical examination, and pharmacological, electrophysiological, and immunological testing. Stapedial reflex abnormalities are noted, so the stapedial reflex decay test (SRDT) can be attempted. There are no reports regarding the SRDT in Korea. We report a case of MG presenting hyperacusia and ptosis that was diagnosed by the SRDT. We recommend using the SRDT in the clinical diagnosis of MG.
