A round mass arising from the caudal aspect of the right zygomatic arch was identified by computed tomography (CT). The histopathologic diagnosis was a low\u2010grade spindle\u2010cell tumor. Surgical resection was planned to achieve 5\u2009mm margins. A patient\u2010specific osteotomy guide and polycaprolactone\/beta\u2010tricalcium phosphate (PCL\/\u03b2\u2010TCP) scaffold were produced. Osteotomy, including 30% of total zygomatic arch length, was performed using an oscillating saw aligned with the guide. The scaffold was placed in the defect. Parosteal osteosarcoma was diagnosed based on histopathological examination. Excision was complete, with the closest margin measuring 0.3\u2009mm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Mild epiphora, due to surgical site swelling, subsided after 20\u2009days.
