[Research progress of clinical application of medial sural artery perforator flap].

[OBJECTIVE] To review the research progress of the clinical application of the medial sural artery perforator flap (MSAPF).

[METHODS] The relevant domestic and abroad literature on the clinical application of MSAPF was extensively consulted, and the research progress were summarized and analyzed in aspect of its definition, anatomical characteristics, clinical application, surgical resection and improvement, and advantages and disadvantages of flaps, etc.

[RESULTS] MSAPF has the advantages of relatively constant anatomical position, thin flap texture, long vascular pedicle, large vessel diameter, no sacrifice of main blood vessels, concealed donor site, no hair, and fewer complications; it can carry nerves, tendons, and muscles to construct chimeric flaps to repair three-dimensional wounds; and can also repair wounds with high aesthetic and functional requirements such as hand, foot and ankle, head and neck, etc.

[CONCLUSION] The MSAPF is a versatile, various forms, functional diversification, and three-dimensional flap donor site with various application forms and ideal repair effectiveness.
