Stickler syndrome is a group of genetic conditions characterized by a distinctive facial appearance, eye abnormalities, hearing loss, and joint problems. A characteristic feature of Stickler syndrome is a slightly flattened face. This appearance is due to underdeveloped bones in the midface, including the cheekbones and bridge of the nose. A specific group of physical features called Pierre Robin syndrome is also common in people with Stickler syndrome. Problems with the bones of the spine can also occur, including abnormal curvature of the spine (scoliosis) and flattened vertebrae (spondylosis). Researchers have described several types of Stickler syndrome, distinguished by their genetic cause, signs, and symptoms. In this article, we will provide useful information to better understand Stickler syndrome.

Newborns like to use their mouths in various ways. When parents notice their newborns sticking out their tongues and chewing, they might wonder if this behavior is normal. The short answer is yes; it is completely normal for newborns to stick out their tongues at this age. However, sometimes it can be a signal of something the baby wants to express or an underlying condition.
