Mohs microsurgery is a technique described by Dr. Frederic Mohs (1910-2002) at the University of Wisconsin. The purpose of Mohs microsurgery is to remove all tumors while retaining as much normal tissue as possible. Initially he used fixed tissues, and by the 1960s he started using fresh frozen tissue. Frozen tissue technology was originally applied to basal cell carcinoma of the eyelid. In the Moh procedure, the tumor that is visible to the naked eye is removed first, and then a thin horizontal slice of the tumor edge is examined under a microscope. Any tiny tumor "root" will be mapped into the original tissue and resected, so it is the best choice for both beauty and treatment. This process needs to be repeated until there is no tumor.

1. High cure rate of skin tumors

2 Avoid unnecessary enlargement of surgical wounds.

This surgical technique has not only become a routine method for removing skin tumors in developed regions in Europe and the United States, but is also recognized as a milestone in the development of skin surgery.

In the early 1830s, Mohs (Frederic E. Mohs), who was still a medical student, studied under Professor Michael F. Guyer in Constance. Professor Guyer was then the head of the school's zoology department and an outstanding geneticist. Together, they experimentally studied various stimuli, and the tumors and normal tissues of mice exhibited different inflammatory responses to the stimuli. In the course of the experiment, they accidentally discovered that not only tumor tissues and normal tissues would be necrotic after the injection of zinc chloride solution, but also the structure and even the cell morphology of these necrotic tissues were well preserved under the microscope. In 1944, Mohs applied for a patent to the Alumni Research Fund, Cons. For the next ten years, as a pioneer and advocate of fixed technology in organizations, Mohs was also the only practitioner of this new technology. In 1956, Mohs published his first monograph on "Chemical Surgery." Because of his long-term unremitting exploration and practice, and because of his rigorous and pragmatic spirit, the good effect of "chemical surgery" has shaken the dermatology community, and the technology has finally been recognized worldwide.

In 1986, due to the dominance of the application of fresh tissue technology, the American College of Chemical Surgery officially changed its name to the American College of Microsurgery and Dermatology (ACMMSCO). From then on, "chemical surgery" will definitely become "Mohs microsurgery."

In summary, Mohs microsurgery is not generally considered to be a fine operation under the microscope, but refers to surgical resection, chemical tissue dependent section or special frozen section detection methods (horizontal frozen section and staining) and prosthetic repair techniques. hybrid. It requires the implementer not only to have a solid foundation in dermatology, especially histopathology, but also to be proficient in a variety of fields such as shaping and beauty.
