P2.78. Prelaminated free flap for the reconstruction of maxillary defects

ackground and Objectives: Infraorbital low-out fracture (IOBF) is an uncomon midfacial trauma, and impairs eyeball unction and causes aesthetic problems. he extraoral approach can lead to some omplications such as scarring, ectropion, nd entropion. The intraoral approach, uch as a transantral approach, has advanages such as no visible scaring, it can be sed to simultaneously treat a zygomaticoaxillary complex fracture (ZMCF), and he procedure is relatively easy. ethods: IOBFs were reduced from the axillary sinus, and fixated internally sing miniplates and screws with/without edpor® (Porex, Newnan, GA, USA) ia a transantral approach. We used this echnique in 11 patients who had an infeior blow-out fracture. Patient’s records nd computed tomography scans were eviewed. esults: The mean age of the patients as 37 years (range, 15–68 years). The ean follow-up period was 9.8 months range, 1–24 months). Before the surgery, he patients had orbital symptoms: diplopia n 3 patients; enophthalmos in 4; and aze limitation in 3. All patients showed eriorbital swelling and ecchymosis. After urgery, none of the patients had diplopia, aze limitations, and enophthalmos. There ere no orbital symptoms or sinus sympoms due to an infection or allergic reaction fter surgery except in 1 patient. In 1 atient, maxillary sinusitis developed 4 months after surgery which subsided with antibiotic therapy after plate removal. Conclusion: We think this technique offers an easy approach, and produces reliable, satisfactory results in IOBF.
