Experimental flap surgery aims to increase our understanding of flap physiology and to test new surgical techniques to increase flap viability. Many experimental flap models have been described with the advancement of flap surgery and research. Most commonly used experimental flaps used in rats, including dorsal skin, flank, epigastric, oblique groin, pectoral, latissimus dorsi, rectus abdominis and fibula flaps, will be described.

Mohs micrographic surgery (MMS) is used to obtain clear margins in skin cancer treatment. MMS involves staged excisions and complete margin assessment of the specimen from fresh tissue frozen sectioning. It has been shown to achieve higher cure rates with malignancies, including basal cell carcinoma (BCC), squamous cell carcinoma (SCC), lentigo maligna, melanoma in situ and dermatofibrosarcoma protuberans. This technique is especially useful in face, feet and hand regions to avoid cosmetic deformities.
