The SAMEO\u2010ATO classification, established by the International Otology Outcome Group (IOOG), provides a comprehensive framework that categorizes surgical interventions into key components, covering both mastoid operations (SAMEO) and middle ear surgeries (ATO).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed correlations between specific subgroups within the SAMEO\u2010ATO framework and the duration of surgery.
