Hanhart's syndrome with special reference to temporal bone findings.
We report two cases of Hanhart's syndrome. The first patient was a male who died in the neonatal period, and whose temporal bones were removed, processed, and histologically examined; the findings are presented in this article. The second case concerns a living patient with the typical characteristics of the syndrome. An attempt is made to show that a gross first and second branchial arch anomaly exists in this syndrome and not just the micrognathia that is obvious to the onlooker. Possible causes and classifications of facial dysmorphia are discussed.
