We describe a technique for sensory nerve conduction study of the mental nerve. A monopolar recording needle is placed near the mandibular foramen using the same approach as that for routine inferior alveolar nerve block in dentistry, and a surface reference electrode is positioned over the ipsilateral mastoid process. Sensory nerve action potentials to stimulation of the mental nerve at the chin can be reliably recorded orthodromically in normal healthy subjects. The method is simple and well tolerated and provides a useful means to evaluate mental nerve function electrophysiologically.
