Poland syndrome is a congenital anomaly characterized by unilateral underdeveloped or absent chest wall, accompanied by varying degrees of ipsilateral limb defects. In clinical practice, Poland syndrome is prone to misdiagnosis and missed diagnosis, which delays treatment timing and affects treatment effectiveness, as the current etiology is not yet clear and there is no unified and standardized clinical classification and treatment plan. This article summarizes and elaborates on the etiology, clinical manifestations, classification, diagnosis, and treatment of Poland syndrome by reviewing relevant literature on the diagnosis and treatment of Poland syndrome both domestically and internationally in recent years, in order to enhance understanding of Poland syndrome, provide reference for standardized clinical diagnosis and treatment, and improve the efficiency of diagnosis and treatment.
