Horner syndrome is characterized by myosis, ptosis, anhydrosis and flushing on the affected side, as well as weakness of the upper and lower extremities due to paralysis of the ipsilateral cervical plexus. It may ocur during intrapleural blocks, thoracal, lumbar, and caudal approach to epidural anesthesia. A female patient, who underwent vaginal hysterectomy and cystorectocele repair under spinal anesthesia, presented with ptosis of the right eyelid at the 30th postoperative hour. She was counseled to anesthesiology with the suspicion of an anesthesiologic complication. She recovered spontaneously after one month. We are in opinion that this complication occurred due to patient's physical characteristics and surgical positioning rather than anesthesic techniques and medications.
