Ear trauma caused by a yucca plant leaf spine.

Three uncommon cases of ear trauma caused by a yucca plant leaf spine are presented. One patient presented with tympanic perforation and the second with mixed hearing loss after spontaneous closure. The third patient probably had a perilymphatic fistula with subsequent labyrinthitis and hearing loss. Although the yucca is a ubiquitous plant, to the best of our knowledge, such incidents have not been previously reported.
