[Long-term outcome of the donor site after free, microvascular pedicled iliac crest transplantation: experiences with 95 cases].

Using the anterior iliac crest as donor-site for free osseous, osseomuscular, and osseomyocutaneous flaps has proven itself an important reconstructive instrument both in maxillofacial and in orthopaedic surgery. We present a long-term retrospective evaluation of the donor-site situation after vascularized free anterior iliac crest transfer. The study is based in 95 cases from the years 1985 to 1993 including 11 cases from Switzerland (Kantonsspital Aarau).

Histomorphometric examinations of free revascularised iliac crest bone after transplantation for mandibular reconstruction.

At the present time the vascularised bone graft is the best procedure for reconstruction of mandibular defects in poor recipient tissues. We obtained 23 drill biopsies from different regions of vascularised bone transplants during the removal of the osteosynthesis plates from 14 patients who had poor recipient tissues. For comparison, we took five biopsies from the native iliac crest and eight biopsies from six patients with avascular bone transfer into unimpaired surrounding tissues.

[Indications for 76 free surgical flaps for mandibular reconstruction].

Since 1985 76 revascularized osseous and osseocutaneous flaps collected from different donor sites were transferred. The overall rate of success amounted to 94.7%, 48.

Histological evaluation of free revascularized iliac crest bone after transplantation for mandibular reconstruction.

Differing views on the nutritional status of revascularized bone in animal studies and in human transfer have been expressed. Normal viability is reported as well as single cell necrosis and devitalized areas and, finally, necrosis of the complete graft. From 19 patients with revascularized bone transfer into injured recipient tissues, we obtained 32 drill biopsies out of the centre of the graft and near the mandibular stump during the removal of the osteosynthesis plates.
