目的 探讨口腔肿瘤向下颌骨内侧面浸润蔓延的传播扩散途径模式以及在微创术中保留下颌骨的可行性。方法 将 6 0例 12 0侧成人下颌骨以染料浸泡后 ,在 10～ 2 0倍的体视显微镜下进行观察。结果 在经染料浸泡的标本上 ,渗入着色剂的副孔清晰可见。在不同的下颌骨 ,着色副孔总数差异很大 ;在下颌骨内侧面 ,上区的着色副孔数比下区的少 ;在上区 ,下颌切迹部的着色副孔数最多 ;在下区 ,中部的着色副孔数最多 ;在下颌孔的内侧面着色副孔的出现率最高。结论 口腔肿瘤经下颌骨内侧面的副孔向下颌骨浸润扩散是口腔肿瘤向下颌骨浸润蔓延的传播扩散途径之一 ;口腔肿瘤一旦侵及骨髓腔 ,便可在下颌骨内经下颌管迅速传播扩散至其它部位。
OBJECTIVE: To explore the mode of transmission and dissemination of oral tumors spreading to the medial side of the mandible and the feasibility of preserving the mandible in minimally invasive surgery. Methods 60 adult adult mandibles were dyed with dye and observed under a stereomicroscope of 10 ~ 20 times. As a result, the secondary pores penetrating the colorant were clearly visible on the dye soaked specimens. In the different mandibulas, the total number of collateral paratoms differed greatly. In the medial mandibula, the number of collateral paired holes in the upper area was less than that in the lower area. In the upper area, , The number of coloration in the middle of the largest number of holes; the inner side of the mandibular hole in the appearance of the highest incidence of coloration. Conclusion Oral tumor spreads to the mandibular bone through the accessory hole of the medial mandibular surface is one of the routes of spread and spread of oral tumor to the mandibular bone. Once the oral tumor invades the bone marrow cavity, it can spread rapidly through the mandibular canal in the mandible. To other parts.
