Tessier Clefts Revisited With a Third Dimension

Abstract

The classification by Tessier of rare craniofacial clefts brought, for the surgeon , order to a previously confusing array of anatomic and developmental descriptions. An ordered two-dimensional categorization of severe clefting malformations evolved from his clinical, radiologic, and surgical observations. The purpose of this paper is to report a complete series of facial clefts studied with computed tomography (CT) and three-dimensional reconstruction. The CT analysis supports some, but contradicts other, hypotheses and speculations presented by Tessier. The CT data reveal the scale of the reconstructive challenge and allow the assessment of our therapeutic interventions.
