First-Reported Mastoidectomy Performed On Gorilla At San Diego Zoo Safari Park

Veterinarians at the San Diego Zoo Safari Park, in collaboration with UC San Diego Health surgeons, successfully performed the world's first reported mastoidectomy on a western lowland gorilla named Mizani. The 12-year-old gorilla underwent the five-hour procedure in March to treat severe sinusitis and mastoiditis. Following the complex surgery, which involved over 20 medical professionals, Mizani has made a full recovery from the infection that had spread into his skull.
