A member asked:

What will make your sinus cavities sink in and leave black sores on your face?

A doctor has provided 1 answer

Not likely: Your sinuses are skin lined cavities in your skull at several different paired sites. Being enclosed in solid bones, they cannot sink in. So whatever causes your face to sink in and causes black sores on your face, it is not your sinus. See an dermatologist to determine the black sores and its cause.
