[Combined vascularized iliac osteo-musculo-cutaneous flap with zygomatic implant anchorage in reconstructing 1 case of maxillary defect].
OBJECTIVE
To reconstruct the maxillary defect by using free vascularized iliac osteo-musculo-cutaneous flap combined with immediate zygomatic implantation for early rehabilitation of maxillary contour and masticatory function.


METHODS
In August 2003, the patient presented with deformity of left middle face (Brown II type defect) after subtotal maxillectomy. After hospitalization, a set of preoperative preparations were made, including spiral CT scanning, manufacture of nature size anatomical model and implantation protocol design. The maxillary defect was reconstructed with free vascularized iliac osteo-musculo-cutaneous flap combined with simultaneous insertion of one Bränemark zygomatic implant and two general implants. Six months later the prosthesis were placed.


RESULTS
The vascularized osteo-musculo-cutaneous flap survived, the osseointegration was observed between bone and implant 6 months later. The contour of face and palate was satisfactory, the normal occluding relation was gained. The average masticatory force of operative side was 76.3% of the normal side. No tumor recurrence was noticed during the follow-up of 14 months.


CONCLUSIONS
It is a reliable method for functional reconstruction of maxillary defect via vascularized iliac osteo-musculo-cutaneous flap combined with immediate zygomatic implantation.
