Abstract

Objectives. The aim of the study was to gather information on outcomes and effect sizes of 2 surgical methods of glossectomy by using a grade system and an objective measure of artifacts in micrometers (mm). The collected data would be used to plan a definitive study. Study Design. Pilot study. Setting. Tertiary referral center. Material and Methods. Nineteen patients affected with tongue cancer were consecutively enrolled in a pilot study and treated by partial glossectomy. Eleven patients (57.89%) of group A were treated with monopolar electrocautery, while 8 patients (42.10%) of group B were treated with Harmonic Focus Curved Shears. Specimens were examined by a pathologist blinded to the surgical procedure, using a 4- grade system for margin artifact assessment (margin fragmentation, cautery/crush artifact, extravascular blood clot, capillary congestion) and for measuring artifact depth. Results. Artifact depth was more relevant in group A (765,633 mm) than in group B (473,939 mm). The difference between groups was significant at the 95% confidence interval (P
