Together, basal cell and squamous carcinomas account for more than 50% of all new cases of cancer. Frozen section biopsy is often used in areas such as the head and neck, in which a wide margin could cause disfiguring scars or difficulties with reconstruction, but the results of frozen biopsy do not always correspond to the results of paraffin sections. This paper aims to review existing literature on the correlation between the results of intraoperative frozen biopsy and final pathological examination of surgical specimens (examination of paraffin sections), because of the importance of frozen biopsy in curative resection and reconstruction of affected sites. A literature review was conducted, based on scientific articles published over the previous 10 years about the accuracy of intraoperative frozen sections. Frozen section biopsy is an efficient and reliable method that should be applied in areas where resection should be as economical as possible. However, in cases with small tumors and excess skin, the results of frozen biopsy are poor, dispensable, and not meaningful. Frozen biopsy is an efficient, affordable, and reproducible method when performed by experienced staff in well-selected cases.
