摘　　要：目的 探讨肿瘤细胞向下颌骨播散途径。方法 对82例下颌骨外侧面下颌副孔进行研究并统计分析。结果 各标本之间下颌副孔数差异很大。冠区下颌副孔出现率为23．17%;切迹区32.93%;髁区 37．80%。上区、中区和下区出现率分别为62．20%,62．20和53．66%。结论 下颌副孔为肿瘤细胞播散到下颌骨提供有效途径。ve To assess the route of spread of the tumour cell to the mandible. Methods The accessory foramina of 82 mandible on the lateral surface were studied and statistically analysed. Results It was found that the number of accessory foramina varied greatly from specimen to specimen. Only 23. 17% of mandibles showed foramen in the coronoid; 32.93% in the sigmoid; 37. 80 % in the condylar section. The fo ramina in the upper third section were 62.20 % ; 62.20% in the middle third and 53.66% in the lower third sections. Conclusion The foramen could provide efficient route for tumour cells spread to the medulla of the mandible.
