Hearing improvement between EES and MES was evaluated, including the postoperative pure tone average (PTA) and air-bone gap (A-B Gap), as well as the hearing threshold across the low-, mid-, and high-frequency. The success rate of grafts was collected. Linear regression was performed to access the prognostic value of preoperative PTA and A-B Gap. Patients were followed up for at least 3\u2009years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The graft success rate of EES was 89.66% (78\/87) versus 80.49% (66\/82) for MES. The postoperative PTA and A-B Gap demonstrated significant improvement in EES compared to MES (Post-PTA: t\u2009=\u20093.281, P\u2009=\u2009.001; Post-A-B Gap: t\u2009=\u20092.197, P\u2009=\u2009.029). In the EES group, there were 59 ears (67.82%) with a postoperative A-B Gap \u226420\u2009dB HL, which revealed a higher rate of successful hearing outcomes in EES as opposed to MES (\u03c7\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u20099.904, P\u2009=\u2009.019). There were significantly better hearing improvement, shorter surgical times, and lower hospital stays in EES for epitympanic cholesteatoma without stapes superstructure involvement. The preoperative AC \u226479\u2009dB and\/or preoperative A-B Gap \u226452\u2009dB was associated with a better prognosis in EES for epitympanic cholesteatoma with stapes superstructure involvement.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>EES showed higher graft success rate, better hearing improvement, shorter surgical times and hospital stays for attic cholesteatoma, particularly without stapes superstructure involvement.
