Purpose: The esthetic and functional rehabilitation of oncologic patients subjected to major resection surgery constitutes one of the greatest challenges for the head and neck surgeon. Immediate bone reconstruction with microsurgical free tissue transfer and dental implants has constituted a genuine revolution in the management of such patients. Materials and Methods: We present a series of 111 oncologic patients, involving a total of 706 implants, who underwent reconstruction with pedicled or free microsurgical flaps. Results: The osseointegration success rate was 92.9%, with a global failure rate (malpositioning or failed osseointegration or loading) of 15%. Failure particularly affected the group of irradiated patients and those subjected to lateral osseomyocutaneous trapezial pedicled flap reconstruction. Excellent results were obtained with the fibular and iliac crest free flaps and osseointegrated dental implants. Conclusions: The difficulties of prosthetic rehabilitation are discussed, along with the individualized solutions applied, the repercussions on the temporomandibular joint, and the management protocol adopted by our service.

Purpose: Oncologic patients undergoing segmental mandibulectomy with soft tissue resection develop several esthetic and functional sequelae; therefore, the defect must be reconstructed immediately. The iliac crest flap is the only flap that allows reconstruction of the previous dimensions of the mandible. However, the excessive soft tissue of this flap prevents optimal reconstruction of intraoral soft tissue defects. Materials and Methods: This report describes a reconstructive technique used in 12 patients who underwent segmental mandibulectomy because of soft tissue defects resulting from tumor resection. The technique involves reconstruction of the mandible using an iliac crest flap combined with a nasolabial flap to enable subsequent reconstruction of the intraoral soft tissue and immediate placement of osseointegrated implants. Results: The osseointegration success rate was 95.2% with a failure rate of 4.8%. Failure particularly affected the irradiated patients. Excellent functional and aesthetic results were obtained with the iliac crest free flap, nasolabial flap and osseointegrated dental implants. Conclusions: This technique has several advantages. On the one hand, it enables reconstruction of the original dimensions of the mandible, thus allowing immediate placement of implants in an ideal position for subsequent rehabilitation with a dental prosthesis. On the other hand, the nasolabial flap provides a thin layer of tissue that can be used to reconstruct the anatomy of the oromandibular soft tissue. [Copyright &y& Elsevier]
