[Transient unilateral sudden hearing loss after spinal anesthesia]. / Spinal anestezi sonrasi gelisen geçici tek tarafli ani isitme kaybi.

Hearing loss after spinal anesthesia is one of the rare complications. It has been suggested that low frequent hearing loss develops after the development of endolymphatic hydrops in the cochlea due to CSF escape after dural puncture. Hearing loss after nonotologic surgical procedures is very rare and usually can only be determined by audiometric evaluation. We aimed to present the sudden unilateral hearing loss and healing process in a patient who underwent spinal anesthesia for elective anterior cruciate ligament surgery in this postoperative period.

[Horner syndrome following combined spinal-epidural anesthesia]. / Kombine spinal-epidural anestezi sonrasi Horner sendromu.

Horner syndrome is rarely observed in connection with epidural anesthesia. It is characterized by ptosis, enophthalmos, miosis, anisocoria, and conjunctival hyperemia in the affected eye, as well as anhydrosis and flushing on the affected side of the face. It is usually a complication spontaneously resolved without permanent neurological deficits. Intraoral anesthesia; stellate ganglion, cervical or brachial plexus blocks; thoracic, lumbar or caudal epidural anesthesia, and intrapleural analgesia are the main causes for Horner syndrome related to anesthesia. Among other causes of Horner syndrome are head and neck surgery, trauma, and puncture of internal jugular vein. The present case of unilateral Horner syndrome appeared in the aortobifemoral bypass after lumbar spinal- epidural anesthesia.
