Radiologic and histologic assessment of diced cartilage grafts for cranial bone defects of rabbits: an experimental study.

This study was performed to experimentally evaluate the viability and coverage of diced cartilage grafts for cranial defects. Biparietal bone defects were prepared in each of 20 rabbits. Otogenous bone grafts were fixed to one side, whereas cartilage grafts taken from the right ear, diced, and wrapped with oxidized regenerated cellulose (Surgicel) were placed on other side.

Proboscis lateralis: report of two cases.

Proboscis lateralis is a rare congenital anomaly and heminasal aplasia is the most common associated anomaly. The proboscis is an ideal donor structure that has good colour and texture match to reconstruct the heminose and should not be sacrified. We present the staged reconstruction of two patients using a subcutaneous tunnel method.
