Maxillary reconstruction using free rectus abdominis myocutaneous flap combined with vascularized costal cartilages

We describe two cases of zygomaticomaxillary bone defect after the resection of a maxillary carcinoma, reconstructed using a rectus abdominis myocutaneous flap combined with vascularized costal cartilages. Eighth and ninth costal cartilages could be harvested connecting with the rectus abdominis muscle. The zygomaticomaxillary buttress was reconstructed using vascularized costal cartilages, while the nasal and oral lining, or facial skin defect were reconstructed with a RAM flap. The shape of the harvested costal cartilages fitted the zygomaticomaxillary bone defect; thus, the result was favorable cosmetically.
