The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla.

The danger triangle of the face is a triangle with two corners at both corners of the mouth and one corner in the middle of the nose between the eyes.

This has clinical importance in that infections of the nose and nearby areas can be transmitted to the meninges and brain from what is known as the danger triangle of the face.

The medial angle of the eye, nose and lips (known as the danger triangle of the face) usually drain through the facial vein, via the ophthalmic vein through the cavernous sinus.
