Gaten Matarazzo has shared a pic of him hospital as he is awaits a fourth surgery on a rare birth defect.
The 17-year-old Stranger Things' star, who plays Dustin in the hit Netflix series, posted a selfie from his hospital bed as he had another surgery for a genetic disorder called Cleidocranial Dysplasia.
The actor has suffered the disorder from birth which affects the bones in his skill, specifically around his mouth.
As he prepared to go under the knife, the actor captioned the photo: "Surgery number 4! This is a big one!"
He continued, "To learn more about Cleidocranial Dysplasia and how you can help those with the condition you can go to ccdsmiles.org."
Gaten did not detail exactly what the surgeons would be working on.
According to details about the condition, "Cleidocranial dysplasia is a rare skeletal dysplasia characterised by short stature, distinctive facial features and narrow, sloping shoulders caused by defective or absent collarbones (clavicles)."
Other major symptoms "may include premature closing of the soft spot on the head (coronal), delayed closure of the space between the bones of the skull (fontanels),and narrow and abnormally shaped pelvic and pubic bones and deformations in the chest (thoracic region)."
To add to this, there is also the "delayed eruption of teeth," and issues with the mouth.
Gaten has become famous in Stranger Things in part for his character Dustin's appearance and voice.
Speaking in an interview on The Doctors, Gaten said: "It’s one of the reasons why I haven’t been getting roles, because of my lisp, and the teeth situation, and my height.
"That affected pretty much everything. I would go three times a week for auditions all the time and get constant ‘no’".
There were plenty of messages of support for Gaten in the comments on his Instagram, with one fan posting: "Hope u have a speedy recovery."
Another added: "You got this dude. You got this, Gaten. You are one strong kid."
