异位涎腺组织可见于头颈部各区域。下颌骨的异位诞腺常并有所谓的下颌骨发育缺损。含有涎腺组织或其他软组织的腔或隐窝可造成下颌骨舌侧骨板穿孔。从缺损部切取的组织或涎腺造影证实为涎腺组织,脂肪组织,淋巴组织及肌肉。因此,涎腺或其他软组织的增生可造成下颌骨浸蚀,形成骨缺损,但其病因尚不清楚。作者报道X线发现的10例所谓下颌骨
Ectopic salivary glands can be seen in various areas of the head and neck. Ectopic glands of the mandible often have so-called mandibular dysplasia. Cavities or crypts containing salivary gland tissue or other soft tissue can cause perforation of the mandibular lingual plate. Tissues or salivary glands excised from the defect were confirmed as salivary gland tissues, adipose tissue, lymphoid tissue and muscle. Therefore, salivary glands or other soft tissue hyperplasia can cause mandibular erosion, the formation of bone defects, but its etiology is not clear. The authors report 10 cases of so-called mandible found on the X-ray
