Accessory nerve palsy: an uncommon etiology.

Accessory nerve palsy due to surgery in the anterior triangle of the neck is uncommon. Two such cases 1, after a carotid endarterectomy and the other after rhytidectomy, are described here. Both cases were treated with analgesics and physical therapy. Followup evaluation after 1 year revealed complete clinical and electrophysiologic recovery in only the first case. Recognizing accessory nerve palsy after surgical procedures in the necks is emphasized as important for proper management. An attempt is made to explain the reason for lack of improvement in the second case.

Tarsal tunnel syndrome: electrophysiological study.

Tarsal tunnel syndrome (TTS) is a rare compression neuropathy of the posterior tibial nerve. Typical symptoms are burning pain and paresthesia in the toes and along the sole of the foot. The presence of Tinel's sign and objective sensory loss in the territory of any of the terminal branches of the posterior tibial nerve are diagnostically helpful. The terminal latency and sensory nerve conduction velocity in medial and lateral plantar nerves were studied in 20 normal controls and 21 cases of TTS in 17 patients. Prolonged terminal latency was observed in 11 cases, with TTS, while sensory nerve conduction abnormality (either absent nerve potential or slow sensory nerve conduction velocity) was found in 19. The sensory nerve conduction velocity in the lateral and medial plantar nerves is a superior objective diagnostic index of TTS.

Meralgia paresthetica: electrophysiologic study.

Conduction velocity of the lateral femoral cutaneous nerve was studied orthodromically. The mean value in 20 control subjects was 57.51 +/- 8.61 (SD) m/sec. In 9 patients with meralgia paresthetica, the sensory nerve condition in the symptomatic nerves was definitely abnormal: nerve potential was absent in 6 and condition velocity was slow in 3. In 1 patient, a possible asymptomatic entrapment neuropathy was suggested by this test. Conduction velocity of the lateral femoral cutaneous nerve can be used as an objective diagnostic aid in meralgia paresthetica.
