A new method for the correction of hypertelorism with preservation of the olfactory nerve filaments.

A method for the preservation of the olfactory nerve filaments in cases of hypertelorism correction is described. The cribriform plate is completely resected and the nerve filaments gathered in the midline after medial rotation of the orbits. In contrast to Converse's (1970) procedure of paramedian osteotomies the method allows full correction of all degrees of hypertelorism, even in the most extreme cases, without olfactory nerve impairment.
