RESUMO
Background: The management of intraosseous mandibular tumors in children is challenging. This study investigated clinical and pathological characteristics, surgical treatment, and outcome of pediatric benign intraosseous mandibular tumors. Materials and Methods: A prospective study included patients under 18 years presenting with benign intraosseous mandibular tumors that were surgically managed. Clinical and surgical data were collected and statistically analyzed. Results: The study included 84 patients (38 males and 46 females): 66.7% had non-odontogenic tumors and 33.3% had odontogenic tumors. The most common non-odontogenic tumors were central giant cell granulomas (31%). The most common odontogenic tumors were odontomas (9.5%). Conservative surgery and radical resection were performed equally. Curettage was the commonest treatment modality (27.4%). Fifty percentage of cases required reconstruction, which was done by costochondral rib graft (42.9%) and free fibula flap (7.1%). One patient had recurrence. All cases got good functional and aesthetic results. Conclusion: Non-odontogenic tumors were more common than odontogenic tumors. Central giant cell granulomas were the most common non-odontogenic tumors, while odontomas were the most common odontogenic tumors. Treatment depended on type, size, and aggressiveness. Pediatric mandibular reconstruction with costochondral rib grafts was simple and satisfactory. Microsurgical reconstruction had high success rates. Appropriate management achieved good aesthetic and functional outcomes.
RESUMO
INTRODUCTION: 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. AIM OF THE WORK: To investigate the clinical and pathological patterns, treatment, and outcome of benign intraosseous maxillary tumors in adolescents. PATIENTS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
