Abstract

Surgical resection tumors in the maxillofacial region sometimes results in extended defects of soft and hard tissue that frequently causes aesthetic, functional and especially mental damages. It is essential for patients with such facial defects to reduce the scar and maxillofacial asymmetry. To attain esthetic facial appearance after hemimaxillectomy, we devise a new design, so called 'IOIO Incision'(InfraOrbital-IntraOral incision). The new approach is established on infraorbital region to expose maxillofacial skeleton in aspect of face. And the other incision is designed is established oral region. The IOIO incision provide excellent aesthetic result after hemimaxillectomy, because of reduced minimal facial scar contraction. Maxillofacial surgeons are used to designing Weber-Fergusson incision in resection of maxillofacial tumors, but disadvantages of the incision were large scar and asymmetry of face. To improve theses problem, we attempted IOIO Incision.. For correct osteotomy of posterolateral wall of maxillary sinus, 1. Fenestra formation on zygomatic body for easily access of reciprocationg saw to postero-lateral wall of maxillary sinus. 2. To achieve better visual field in posterolateral aspect of maxilla, fat tissue is removed from infratemporal fossa. This new, versatile procedure can be used for benign and malignant lesions of the maxillary area. We introduce cases with review of literatures.
