After anesthetizing the animals, a 6\u2010mm biopsy punch marked the resection margin on the buccal mucosa (one per cheek). The specimens were excised by means of three energy levels, a cold knife, and monopolar diathermy that was set on either 20\u2009W or 30\u2009W cut modes. The specimens were evaluated for extent of contraction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 45 samples were obtained and measured, including 15 specimens in the cold\u2010knife group, 15 specimens in the 20\u2009W group, and 15 specimens in the 30\u2009W group. The median diameters of the specimens after resection were 4.5\u2009mm for the cold\u2010knife group (interquartile range [IQR] = 4.0\u20135.0), 3.5\u2009mm for the 20\u2009W group (IQR = 3.5\u20134.0), and 2.8\u2009mm for the 30\u2009W group (IQR = 2.5\u20133.0). Specimen contraction was 25.0%, 41.7%, and 53.3%, respectively. The difference in shrinkage between each pair was statistically significant: cold knife versus 20\u2009W, <jats:italic>P<\/jats:italic> =\u2009.001; cold knife versus 30\u2009W, <jats:italic>P<\/jats:italic> &lt;\u2009.0001; and 20\u2009W versus 30\u2009W, <jats:italic>P<\/jats:italic> &lt;\u2009.001.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Diathermy power settings result in a significant difference of mucosal tissue contraction, with higher outputs resulting in a narrower mucosal margin.
