Monkey cheeks

Monkey cheek-like depression in the cheeks is one of the clinical manifestations of protein-energy malnutrition. Protein-energy malnutrition (PEM) occurs when the co-feeding of protein and / or calories cannot meet the body's need to maintain normal physiological functions. According to the cause of malnutrition, it can be divided into primary and secondary. Spontaneous, caused by insufficient food. Generally speaking, the buccal fat pad refers to the triangular cheek fat body formed by a piece of fatty tissue protruding from the cheek. It can prevent the cheeks from collapsing during breastfeeding, so cheek fat bodies are more developed in children, and their faces are always fat and round. According to the distribution characteristics of the capsule, vascular source, and fixed ligament, the buccal fat pad is divided into anterior, middle, and posterior lobes, and the posterior lobes emit buccal processes, pterygoid processes, pterygoid processes, and temporal processes to the surrounding space. Each leaf has independent The capsule is fixed on the surrounding tissues by buccal fat pad maxillary ligament, posterior sacrum ligament, medial marginal ligament of infraorbital fissure, lateral marginal ligament of infraorbital fissure, temporal tendon ligament and buccal muscle ligament. Each leaf has an independent source of blood vessels, forming a subcapsular vascular network. The buccal fat pad has filling, sliding, protecting and cushioning effects.
