Facial bipartition in hypertelorism.

In our cases of hypertelorism we used two techniques. In some cases, we used Tessier's original technique (Tessier et al, 1967), and in others the modification suggested by Converse (Converse et al, 1970). In still others, we did not remove any part of the medial portion of the nose, that is, of the nasoethmoidal complex. We can say now, that in the cases operated on during ages of already completed development (14 to 15 years), the follow-up presented satisfactory, if not exceptional results, but in the cases operated on during the first years of life (2 to 10 years) investigation of the results obtained allowed us to make some important observations. In a high percentage of these cases we observed a relapse of the anatomical positions reached by operation. In the cases documented here, the long-term results were inadequate.
