Treacher-Collins Syndrome (TCS)

A hereditary condition called Treacher-Collins Syndrome (TCS) impairs the growth of the bones and other tissues of the face, giving rise to unusual facial traits. 

People with TCS frequently have undeveloped cheekbones, which can give the appearance that their faces are sunken.

The ears of those with TCS may be tiny, malformed, or nonexistent.

Eyes that slant downward.

People with TCS may have eyes that are slanted downward and a notch in the lower eyelids called eyelid coloboma.

Narrow eye openings: People with TCS may have a narrower-than-normal opening between their eyelids, which can make their eyes appear smaller\

Cleft palate: A cleft palate is a split or opening in the roof of the mouth that affects many persons with TCS.

Breathing problems: TCS might change how the face's airways develop, which can cause breathing problems, particularly if you're trying to fall asleep.
