The human face contains numerous subcutaneous compartments of fatty tissue, but neither a chin compartment nor a submental compartment have been described. Definitions of the jowl compartment vary considerably.
To investigate the borders between the subcutaneous fat compartments of the chin, submental region, and jowls.
Colored gelatin was injected into the subcutaneous tissues directly under the skin of 30 human cadaver heads. Macroscopic dissection was performed.
Distinct chin and submental compartments were identified in all cases. The chin compartment is demarcated by the mentolabial groove superiorly, the submental ligaments inferiorly, and the labiomandibular grooves laterally. The submental compartment is demarcated from the chin by the submental ligaments, laterally by the paramedian platysma-retaining ligaments, and inferiorly by the hyoid ligament. The upper border of the jowl compartment is formed by the mandibular ligaments and the platysma-mandibular ligaments, the anterior border by the paramedian platysma-retaining ligaments, and the dorsal boundary by the submandibular platysma retaining ligaments.
The chin compartment is well demarcated from adjacent compartments. The limits of the submental compartment vary. The jowl compartment is clearly demarcated from adjacent compartments.
人体面部包含众多的皮下脂肪组织隔室，但尚未描述颏部隔室和颏下隔室。对于颊部隔室的定义差异很大。
研究颏、颏下和颊部皮下脂肪隔室之间的边界。
将有色明胶直接注入 30 个人体头颅标本的皮肤下的皮下组织中。进行了宏观解剖。
在所有情况下均能识别出明显的颏部和颏下隔室。颏部隔室由颏唇沟在上部、颏下韧带在下部以及唇颏沟在侧面界定。颏下隔室由颏下韧带与颏部隔开，侧面由正中的颈阔肌保留韧带，下方由舌骨韧带隔开。颊部隔室的上边界由下颌韧带和颏肌下颌韧带形成，前边界由正中颈阔肌保留韧带形成，背侧边界由下颌下颏肌保留韧带形成。
颏部隔室与相邻隔室明显分开。颏下隔室的界限变化。颊部隔室与相邻隔室明显分开。
