The Tübingen line is a dural intraoperative anatomical landmark.

Definition

The Tübingen line connects the dural folds between the region of the Foramen jugulare and the Sinus sigmoideus. Intraoperatively, this line appears at the transition from a folded to a smooth dural surface. This dural landmark marks the inferior portion of the Meatus acusticus internus[^1].
