An unexpected finding on histology in a 73 years old patient was an isolated suborbital plexiform neurofibroma. Since this tumor is specific for von Recklinghausen's disease, the diagnosis was that of a minor form of the disease. The different cephalic manifestations of von Recklinghausen's disease are reviewed.
The mask lift, the latest technique for facial rejuvenation, comprises a large remodelling of the frontal and orbito-malar area. The modelling resections by bone-grinding are essentially designed to taise the superior orbital rim, but by the onlay grafts on the malar bone as well as the ones on the superior orbital rim many problems occur due to the donor site (autogenous bone), their biocompatibility and eventual resorption or integration. It is therefore proposed to use BOP S.P. as an onlay graft, a synthetic and biocompatible material already used in neurosurgery for cranioplasties with good results. Its essential advantage over other implants is its wax like consistency and its progressive adhesion to the bone, which allows onlay grafts to be placed wherever required; the modelling is fast, the result are immediately controllable and it is stable after a few hours hardening. BOP S.P. is essentially used as onlay graft material for mask lifts, but has also been successfully tested on 4 facial contour reconstructions for corrections after major traumatic injuries. No complication has been observed in a series of 9 cases but a one year follow-up is too short.
