Benign intraosseous maxillary tumors, although uncommon among the adolescents, represent a major challenge to the maxillofacial surgeons. Treatment ranges from conservative surgery to radical resection and reconstruction. Maxillary defect reconstruction in adolescents is uncommon. it can be achieved by prosthetic obturators, local and regional flaps, and free-tissue transfer.To investigate the clinical and pathological patterns, treatment, and outcome of benign intraosseous maxillary tumors in adolescents.A 10-years prospective study included patients between 12-18 years who presented with benign intraosseous maxillary tumors and surgically treated (conservative surgery or radical resection) with immediate reconstruction. Cases were followed up to assess functional and aesthetic outcomes and detect complications.Study included 38 patients; 63.2% had non-odontogenic tumors and 36.8% had odontogenic tumors. The most common non-odontogenic tumor was central giant cell granuloma (31.6%). The most common odontogenic tumors were adenomatoid odontogenic tumor and ameloblastoma (10.5% each). Treatment included Conservative surgery (55.3%) and radical resection (44.7%). Reconstruction was performed in 17 cases by temporalis muscle flap (9.83%), obturator (2.46%), and free fibula flap (1.64%). All cases gained accepted functional and esthetic results.Non-odontogenic tumors were more common than odontogenic tumors. Central giant cell granulomas and ossifying fibromas were the most common non-odontogenic tumors. Ade-nomatoid odontogenic tumor and ameloblastoma were the most common odontogenic tumors. Maxillary reconstructions with tem-poralis muscle flap and obturator were simple and satisfactory. Microsurgical reconstruction had high success rates. Aesthetic, and functional results were satisfactory when appropriate reconstruction was performed.
