For unknown aetiology, primordial sciatica (also known as ischiatitis) is uncommon in the larynx.
Due to compression or irritation caused by neighboring lesions, secondary sciatica can be divided into root sciatica and trunk sciatica depending on whether the compressed position is nerve root or trunk. Root sciatica is more common which is mainly caused from lumbar disc herniation.
