Primary outcomes were preoperative and pre- to postoperative change in pure-tone average (PTA) and low-frequency air\u2013bone gap (LF-ABG).

Similar findings were seen in the SSCD\u2009+\u2009tegmen tympani dehiscence\u2009+\u2009combined dural\u2013ossicular contact cohort for PTA (B\u2009=\u20095.32; p\u2009=\u20090.017) and ABG at 500\u2009Hz (B\u2009=\u20094.50; p\u2009=\u20090.029) and 1,000\u2009Hz (B\u2009=\u20094.66; p\u2009=\u20090.006). The SSCD\u2009+\u2009tegmen tympani dehiscence\u2009+\u2009unilateral dural\u2013ossicular contact cohort had significantly higher preoperative ABG at 500\u2009Hz (B\u2009=\u20095.11; p\u2009=\u20090.023) and 1,000\u2009Hz (B\u2009=\u20095.18; p\u2009=\u20090.005), whereas the bilateral dural\u2013ossicular contact group showed no significant differences. No cohort exhibited significant changes in PTA or LF-ABG postoperatively.<\/jats:p>\n                  <jats:p>Concurrent SSCD and tegmen tympani dehiscence with or without dural\u2013ossicular contact present with greater preoperative PTA and LF-ABG but no significantly different surgical outcomes compared with SSCD alone.
