Frozen section examination of the margins for resection of squamous cell carcinoma of the lower lip.

Objectives: Our goal was to evaluate the role of frozen section margin examination in the surgical management of squamous cell carcinoma of the lower lip.

Materials And Methods: We reviewed frozen section examination of the resection surfaces of 131 consecutive patients surgically treated for squamous cell carcinoma of the lower lip during the period January 1980 to January 1999. When invasive carcinoma or carcinoma in situ was present at the resection surface, the margin was defined as positive and re-resection was performed.
