口底主要由下颌舌骨肌隔膜构成,其下面由二腹肌前腹加强。多数解剖书和口腔外科专著都给人下颌舌骨肌隔膜形成了口腔完整的底的印象然而这一概念于事实不符。在我们几百次解剖之中,经常遇到下颌舌骨肌肌纤维囊不完整的例子,有的舌下腺穿过开口形成疝而引起我们的注意。尽管比较常见,这种情形在解剖学手册中只浅略提到、解剖学文献很少描述、口腔病理学中则被忽略。这方面的知识对诊断及外科应用可能有实际重要性。
Bottom of the mouth by the hyoid muscle diaphragm, the lower by the anterior abdominal strength to strengthen. Most anatomical books and oral surgery monographs give the impression of the oral hypospadias diaphragm the integrity of the mouth, however, this concept does not match the fact. In our hundreds of dissections, often encountered in the hylobital myofibroblasts incomplete example, some sublingual gland through the opening to form hernia and cause our attention. Although more common, this condition is only briefly mentioned in the anatomy handbook, anatomic literature is rarely described, and oral pathology is ignored. This knowledge may be of practical importance for diagnostic and surgical applications.
