Hairline indicators of craniofacial clefts.

The review of a complete series of Tessier craniofacial cleft patients presenting to the South Australian Cranio-facial Unit has identified within the hairline a regular marker of clefting. Tongue-like projections of the temporal and frontal hairline pointing in the direction of their respective clefts have been identified for Tessier clefts numbered 7 to 14. No hairline indicator was revealed in "southbound" clefts numbered 0 to 6 without "northbound" extension. The hairline markers of laterally and superiorly bound clefts are a complementary element of the Tessier classification system.
