Philtrum
From BMEzine Encyclopedia
(Redirected from Filtrim)
The philtrum is the midline groove of the upper lip which is located between the nose and the top of the lip. It is also a local term for the Medusa piercing.
What's interesting is that this is one of the few cases (others include the daith and rook) where a decorative name has trumped a proper anatomical name.
