Johanson-Blizzard syndrome facial anomaly and its correction using a microsurgical bone graft and tripartite osteotomy.

The facial anomaly of Johanson-Blizzard syndrome and its correction are described. The facial anomaly was characterized by cleft-like bony defects located in the inferomedial portion of the orbit apart from the hypoplastic maxilla and the absence of nasal alae. Correction of the facial skeleton was performed using a free vascularized iliac bone graft and tripartite osteotomy to correct the shape of the orbit and elongate the severely hypoplastic maxilla. Those procedures were effective to a certain degree in correcting the facial anomaly of Johanson-Blizzard syndrome.
