In two patients, the skin over both hypothenar eminences underwent intermittent, spontaneous, irregular, dimpling contractions. The dimpling was benign, and was the result of spontaneous discharge of motor units in the palmaris brevis muscle. Electrophysiological investigations localized the site of origin of the discharge to the ulnar nerve, possibly at the wrist, but there was no clinical or physiological evidence of neuropathy or of nerve compression. In many respects, the clinical and electrophysiological features of hypothenar dimpling resemble hemifacial spasm.
在两名患者中，双侧小鱼际隆起处的皮肤出现间歇性、自发性、不规则的酒窝状收缩。这种酒窝状表现是良性的，是掌短肌运动单位自发放电的结果。电生理检查将放电起源部位定位到尺神经，可能在腕部，但没有神经病变或神经受压的临床或生理证据。在许多方面，小鱼际酒窝状收缩的临床和电生理特征类似于面肌痉挛。
