Ameloblastoma is a histologically benign, locally aggressive tumor arising from the odontogenic ectoderm. It accounts for 1% of all oral tumors and for 9% to 11% of all odontogenic tumors. In up to 96.6%, the tumor can be found in the mandible, predominantly in the molar region. High recurrence rates of up to 90% have been described with conservative treatment. Recurrences most often occur after 2 to 5 years. After radical resection, significantly lower recurrence rates have been reported, sometimes as low as 3.6%. As a consequence, when recurrence rate is the main concern, there is a tendency to prefer radical resection of the ameloblastoma. Microvascular segmental reconstruction of the mandible that uses an intraoral anastomosis technique has not been described in the current literature. Therefore, the present study aimed at extending the armamentarium of bony microvascular reconstruction in cases of segmental mandibulectomy by describing an intraoral microvascular anastomosing technique.
成釉细胞瘤是一种组织学上为良性但具有局部侵袭性的肿瘤，起源于牙源性外胚层。它占所有口腔肿瘤的1%，占所有牙源性肿瘤的9%至11%。高达96.6%的肿瘤可在下颌骨中发现，主要位于磨牙区。保守治疗的复发率高达90%。复发最常发生在2至5年后。根治性切除后，复发率显著降低，有时低至3.6%。因此，当主要关注复发率时，倾向于对成釉细胞瘤进行根治性切除。目前文献中尚未描述使用口腔内吻合技术进行下颌骨微血管节段重建。因此，本研究旨在通过描述一种口腔内微血管吻合技术，扩展节段性下颌骨切除病例中骨微血管重建的手段。
