Frozen Section Examination is a rapid pathology procedure used during surgery to examine a tissue sample and provide an immediate preliminary diagnosis. It is particularly useful when the surgeon needs quick information about the nature of a lesion or tissue while an operation is still in progress. In neurosurgical procedures, frozen section analysis may help assess brain or other nervous system tissue and support real-time surgical decision-making.
What Is a Frozen Section Examination?
During the procedure, a small tissue sample is collected and rapidly frozen in a pathology laboratory. The tissue is then thinly sectioned, stained, and examined under a microscope by a qualified pathologist. The findings are communicated to the surgical team, often within a short period, allowing them to consider the information while the surgery continues.
When Is Frozen Section Used?
A frozen section biopsy may be considered when rapid tissue assessment is important during surgery. It can help determine whether tissue appears benign or malignant, identify the nature of a lesion, or assess whether additional tissue sampling may be required. The test is especially valuable when the result could influence the extent or direction of the ongoing surgical procedure.
Is Preparation Required?
Preparation depends on the underlying surgery and the patient's overall treatment plan. Your surgeon and healthcare team will explain any required preparation and what the pathology findings may mean for further treatment.
