Nine membrane perforations (11.2%) occurred during the study, all within the lower expertise group. Membrane elevation by hand instruments caused five perforations (40%) in the rotary instrument group and one in the piezoelectric group. Expert surgeons produced no membrane perforations, the size of the antrostomy that was smaller in the piezoelectric group being the only significant difference between the rotary and piezoelectric groups.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> The use of piezoelectric material for MSFE reduces the frequency of membrane perforation among surgeons with a limited
