The philtrum is the central unit of the upper lip. The central lip depression, or philtral dimple, is bordered: a. On each side, by a philtral column The junction of the skin and vermilion is
characterized by a linear prominence, named the
mucocutaneous ridge by Marcks1 and referred to as
the "white roll" by Gillies2(p. 142) . Thus, the
philtral unit consists of the dimple, both columns, the
tubercle, and the white roll between the two high points of
cupid's bow. Maintaining the philtrum as a complete anatomic
unit, neither discarding nor cutting into any part of this
unit, is key to achieving excellent results in lip
repair. |
