Sixty\u2010three patients affected by otosclerosis and 63 by chronic otitis media were enrolled. For each disease, patients were divided into three numerically equal groups, with each group assigned to a well\u2010trained otological surgeon. Patients underwent stapedotomy (n = 63) and intact canal wall tympanoplasty (n = 63) with the piezoelectric device.<\/jats:p><\/jats:sec><jats:sec><jats:title>SETTING<\/jats:title><jats:p>ENT Department, University of Genoa (Italy).<\/jats:p><\/jats:sec><jats:sec><jats:title>SUBJECTS AND METHODS<\/jats:title><jats:p>We recorded \u201cskin\u2010to\u2010skin\u201d operation time, surgical success, surgical complication, and hospital stay duration.

A feature of the piezoelectric device is its good manageability, which makes it easy for a well\u2010trained otological surgeon to create a straight osteotomy line without any learning period: this renders the piezoelectric device suitable for bone
