Free microvascular bone flaps used for cavity reconstruction in the head and neck area.

The authors would like to present the possibilities of reconstructive surgery using free microvascular flaps with bone elements in the treatment of cavities in the head and neck area. The cavities in the presented article resulted both from resection of tumors in the head and neck area as well as congenital defects and radiation damage. The authors would like to discuss the difficulties that may arise during the postoperative period, including the maintenance of the graft's viability, the healing of the donor site and systemic problems. The article presents 33 reconstruction surgeries performed on 31 patients using different flaps, briefly describing their advantages and technical difficulties that may arise during the microvascular anastomoses. The authors emphasise the importance of a well-conducted qualification for the surgery as well as the need to discuss the course of the surgery and recovery and other possible treatment options with patients and their families. The complications that happened in the presented group and how they were treated are described. The authors discuss in details the 3 cases with different types of reconstructive procedures and draw attention to the importance of postoperative care consisting of the constant monitoring of the viability of the graft carried out by qualified personnel of the Otolaryngology Department and appropriately conducted anticoagulant therapy.
