Palatal myoclonus generally entails a visible elevation of the palate and uvula and may be accompanied by myoclonus of other oropharyngeal muscles. A 55-year-old man presented with left ear clicking and hyperacusis. Examination showed arrhythmic left lateral soft palate contraction in the tensor veli palatini region without elevation of the uvula, which correlated with an audible click by auscultation with a stethoscope over the left ear. This is a rare case of focal, unilateral palatal myoclonus without visual uvula elevation with concurrent auscultation, demonstrating the importance of careful examination to detect focal myoclonic contractions.
腭肌阵挛通常表现为腭部和悬雍垂明显上抬,可能伴有其他口咽肌的肌阵挛。一名55岁男性出现左耳喀哒声和听觉过敏。检查发现腭帆张肌区域左侧软腭有节律不齐的收缩,但悬雍垂未上抬,用听诊器在左耳听诊时可闻及喀哒声与之相符。这是一例罕见的局限性、单侧腭肌阵挛,悬雍垂无明显可见上抬且伴有听诊表现,证明了仔细检查以发现局限性肌阵挛收缩的重要性。
