title: Comprehensive treatment and rehabilitation of a patient with maxillary arteriovenous malformation.
abstract: Arteriovenous malformations (AVMs) of the maxilla are rare and potentially life-threatening conditions that can pose a therapeutic dilemma. We reported the first case of maxillary AVM in a 15-year-old girl who was treated by marginal hemimaxillectomy including overlying palatal mucosa and immediate replantation of the segment after removing the AVM tissues and teeth and covering by a full-thickness pedicled temporal muscle flap rotated into the mouth. Then, this preserved bone underwent distraction osteogenesis and dental implant rehabilitation successfully. This method was previously used for the definitive treatment of mandibular AVMs, and in this case, we applied this method for the first time in maxillary AVMs. In conclusion, this surgical method may be considered as a safe, convenient, and effective treatment and reconstructive modality for such vascular malformations in the maxilla and restores function and symmetry of the jaws while obviating the need for bone harvesting and future major reconstructive operations.
