New series of surgical design for anterior maxillary reconstruction with deep circumflex iliac artery flap

Microsurgical reconstruction for anterior maxillary defects presents a surgical challenge. The objective of this study was to ascertain the feasibility of a new series of intraoral surgical approach using deep circumflex iliac artery (DCIA) flap to achieve functional reconstruction for anterior maxillary defects. Two male patients with anterior maxillary defects (Brown Class IC) were treated in this study. Both patients underwent computer-assisted maxillary reconstruction with a DCIA flap (with pedicle positioning laterally to the bony flap) using intraoral anastomosis techniques. The overall DCIA flap survival rate was 100% and mucosa was all healed uneventfully. One patient received dental implantation and loaded with prosthetic superstructures. Both patients were satisfied with their postoperative oral function and appearance. This study illustrated a new and feasible series of surgical design for anterior maxillary bone defect reconstruction with DCIA flaps and intraoral anastomosis assisted by digital techniques.
