Overgrowth of a costochondral graft in nasal reconstruction

Nasal reconstruction with autogenous costochondral graft has been one of the surgical managements in craniofacial clefts. We have recently seen one patient who underwent this operation and the graft had overgrown like as in Pinocchio's nose-overly projecting nasal tip for almost 7 years. This case supports the notion that the costochondral graft itself carries intrinsic factors and the growth of the graft depends mainly on the costochondral graft itself. Therefore we acknowledge "the primary growth center theory" rather than "the functional matrix theory".
