  Abstract: Objective To evaluate the application value of dermatoscope combined with quick frozen section examination in the treatment of head and face skin tumors. Methods Retrospective analysis of 123 patients with head and neck skin tumors admitted to the Dermatology Department of Jinhua Municipal Central Hospital from June 2019 to December 2023. They were treated using a combination of skin biopsy and intraoperative rapid frozen section as well as preoperative dermoscopy and intraoperative rapid frozen section assessment.The surgical cure rate of the two methods and the coincidence rate of dermatoscope image diagnosis, quick frozen section diagnosis and paraffin section diagnosis were statistically analyzed and compared.Results There is no significant difference between preoperative dermoscopy combined with intraoperative quick frozen section examination and preoperative skin biopsy combined with intraoperative quick frozen section examination in the treatment of head and face skin tumors. The coincidence rate of dermoscopy image analysis technology and paraffin section diagnosis is 91.36%, and the coincidence rate of quick-frozen section examination diagnosis is 98.37%. All cases reported negative in basal margins by intraoperative quick frozen section and postoperative paraffin section, and no recurrence was found after 6 months follow-up. Conclusion In the surgical treatment of head and face skin tumors, dermoscopy combined with intraoperative rapid frozen section examination has obvious effect, which can replace preoperative skin biopsy and is worthy of clinical promotion.
