At four years after surgery, seven patients had class A, four class B, three class C, and two class F. The mean functional level before surgery was 4.8 and improved to 2.9 and 2.6 at two years and four years after surgery, respectively. The bone conduction pure\u2010tone averages (four frequencies) were 43.3 before surgery and improved to 33.5\u00a0dB HL and 35.5\u00a0dB HL at three and six months after surgery, respectively. At two years of follow\u2010up, the hearing level was 38.6\u00a0dB HL and was not different from the preoperative hearing level. Two years after surgery, the hearing level gradually decreased and was 42.0\u00a0dB HL at five years of follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>EMS
