Cartilage regeneration was histologically evaluated in vivo in the squirrel monkey pinnae. Only 2 of 11 ears exhibited evidence of cartilage regeneration (Movat stain) within the subperichondrial area, eight to nine weeks postoperatively. The present experimental results in squirrel monkeys contradict the previously reported high incidence of ear cartilage regeneration in young rabbits and may reflect a difference in surgical technique, animal species, or animal age.
