Frozen Section Analysis in Submandibular Gland Tumors: Optimizing Intraoperative Decision-Making.

: With around 25 different salivary gland tumor entities described by the World Health Organization, the correct preoperative identification of masses as benign or malignant remains a challenge. If preoperative needle biopsy is inconclusive, frozen section analysis is a possible alternative for accurate histological identification. The purpose of our study was to evaluate the diagnostic effectiveness of frozen section performed for primary submandibular gland masses. : In addition to acquiring epidemiological data from patients who underwent submandibular gland excision over a 20-year period, we analyzed the diagnostic effectiveness of frozen section performed for submandibular gland masses. We also examined the impact of frozen section on overall survival. Furthermore, we investigated whether there was an impact on the surgical revision rate for malignant submandibular gland masses that required additional neck dissection within the submandibular triangle. : Frozen section was performed for 54 submandibular gland tumors, with a specificity of 100% and a sensitivity of 81.3%. Frozen section was conducted in 12 cases of primary salivary gland malignancies, of which 9 cases were identified correctly. In three cases, the frozen section results were inconclusive. We calculated a relative risk reduction of 27% for revision surgery by performing frozen section. There was no significant association between frozen section results and overall survival. : Frozen section demonstrates a significant reduction in the need for revision surgery. With a specificity of 100%, frozen section is especially suited to identifying benign masses. It is a valid diagnostic tool when preoperative sampling is not possible or is inconclusive.
