INTRODUCTION Encephaloduroarteriosynangiosis (EDAS) for moyamoya is predominantly performed using a branch of the superficial temporal artery (STA) as the donor artery. At times, other branches of the external carotid artery (ECA) are better suited for EDAS than is the STA. There is little information in the literature concerning using the posterior auricular artery (PAA) for EDAS in the pediatric age group. In this case series, we review our experience using the PAA for EDAS in children and adolescents. CASE PRESENTATIONS We describe the presentations, imaging, and outcomes of three patients in whom the PAA was used for EDAS, as well our surgical technique. There were no complications. All three patients were confirmed to have radiologic revascularization from their surgeries. All patients also had improvement of their preoperative symptoms, and no patient has had a stroke postoperatively. CONCLUSION The PAA is a viable option for use as a donor artery in EDAS for the treatment of moyamoya in children and adolescents.
