Analyses of the operative efficacy of 102 cases of acquired middle ear cholesteatoma / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy of operations of acquired middle ear cholesteatoma.</p><p><b>METHODS</b>Retrospectively analyzed clinical data of 102 patients whom received tympanoplasty with CWU or CWD with mastoid obliteration in our hospital between January 2014 and December 2014. Patients were divided into different groups according to types of the cholesteatoma as well as the different surgical procedures. Patients were followed up for 12-24 months, the pre and post-operative PTA was performed and evaluated. The post-operative hearing was assessed in terms of average ABG.</p><p><b>RESULTS</b>The average dry ear time was (5.4±1.7)weeks. The dry ear time of patients of attic cholesteatoma was shorter than those of tensa cholesteatoma[(4.9±1.7)weeks vs(6.1±1.5)weeks, t=-3.52, P=0.001]; the dry ear time of patients underwent CWU was shorter than those underwent CWD with mastoid obliteration[(2.3±0.5)weeks vs(5.8±1.4)weeks, t=-8.43, P=0.000]. Mean pre and post-operative air bone gaps in 93 ears underwent ossiculoplasty were (34.2±11.8)dB and (19.0±5.5)dB respectively and these differences were statistically significant. Both the pre and post-operative air bone gaps of ears of attic cholesteatoma were smaller than those ears of tensa cholesteatoma(P<0.05). In the patients who underwent ossiculoplasty with CWD with mastoid obliteration, the post-operative air bone gaps of attic cholesteatoma were smaller than those of tensa cholesteatoma(P<0.05). Both the pre and post-operative air bone gaps of ears underwent CWU were smaller than those underwent CWD with mastoid obliteration(P<0.05). The post-operative air bone gaps of ears underwent PORP with CWD with mastoid obliteration were smaller than those underwent TORP with CWD with mastoid obliteration(P<0.05).</p><p><b>CONCLUSIONS</b>Both the hearing loss and the outcome of tensa cholesteatoma are worser than attic cholesteatoma. The outcome of PORP is better than TORP. The patients who will accept CWU should be selected more carefully and be followed up regularly.</p>
