Clinical value of abnormal median-normal sural sensory response pattern for the early diagnosis of acute oropharyngeal palsy: a comparison of recent and previous cases

To evaluate whether nerve conduction study (NCS) findings are useful to make an early diagnosis acute oropharyngeal palsy (AOP). We evaluated 2 AOP patients. Patient 1: An 18-year-old male who developed a nasal voice two weeks after common-cold symptoms with no weakness in his extremities. Patient 2: A 16-year-old female who developed a nasal voice two days after diarrhea with no weakness in her extremities. We conducted a routine NCS on these 2 patients and followed up their changes. Both patients had an abnormal median-normal sural (AMNS) sensory response pattern, which improved over time. Both patients were diagnosed with AOP and treated with intravenous immunoglobulin (400 mg/kg/day) with a good prognosis. Anti-GQ1b and/or anti-GT1a IgG antibodies were identified in the serum of both patients a few weeks after their initial diagnoses. The AMNS sensory response pattern can be useful for the early diagnosis of AOP.
