Gaten Matarazzo is best known for playing Dustin Henderson on Stranger Things, a role he first began back in 2016 when he was 13-years-old. Matarazzo’s cleidocranial dysplasia was written onto the show and the now 19-year-old actor has been very open about his CCD, “a skeletal disorder characterized by open fontanelles (soft spot), small or absent clavicles (collarbones), and multiple dental abnormalities.” In 2020, the actor underwent his fourth surgery for CCD, which he called a “complete success.” In honor of the upcoming fourth season of Stranger Things, Matarazzo recently spoke with Michael Rosenbaum on his Inside You podcast about the history of Stranger Things and some on-set shenanigans. During the conversation, Matarazzo also opened up about his cleidocranial dysplasia and how it stopped him from getting roles.
