Abstract: PURPOSE : To assess the reliability and usefulness of endoscopic-assisted resection of benign tumors in the maxillofacial region. METHODS : Eighteen benign tumors were located in the maxillofacial region. Among them, seven patients were males and eleven patients were females; the age of the patients ranged from 5 to 34 years (average 16.8 years). The sizes of tumors ranged from 1.7 cm×2.2 cm to 2.0 cm×3.2 cm. Endoscopic-assisted minimally invasive approaches were used for tumor resection. RESULTS : All tumors were successfully resected using an endoscopic-assisted technique. The operation time was 45-75 min while an estimated blood loss was about 6-15 mL(average 8.5 mL). The patients were followed up for 2-8 months, there was no recurrence, and postoperative facial appearance was good. CONCLUSIONS : Endoscopic-assisted resection of benign tumours of the maxillofacial region is a simple and safe technique that achieves excellent aesthetic results.
