Effects of ossicular reconstruction with partial ossicular replacement prosthesis in patients with tympanosclerosis / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of ossicular reconstruction with partial ossicular replacement prosthesis (PORP) in patients with tympanosclerosis.</p><p><b>METHODS</b>The data of 28 cases of tympanosclerosis treated between 1992 and 2006 were reviewed. Of the 28 patients, 14 (14 ears) underwent ossicular reconstruction with PORP and 14 (14 ears) had ossicular mobilization, and all the patients were followed-up for 3-24 months.</p><p><b>RESULTS</b>Significant improvement was found in postoperative speech frequency (500, 1000, 2000 Hz) pure tone average (PTA) and air-bone gap (ABG) closure after in the operation the two groups. Ossicular reconstruction using PORP resulted in statistically better ABG closure and PTA (P<0.05).</p><p><b>CONCLUSION</b>In ossicular attic fixation, ossicular reconstruction using PORP can yield better results than mobilization of the major ossicles in patients with tympanosclerosis.</p>
