RESUMEN
OBJECTIVE To share surgical experience of ossicular chain malformations with CO2 laser.METHODS A retrospective analysis was performed.9 patients with clinical diagnosis of ossicular malformations underwent ossicular reconstruction with CO2 laser-assisted from May 2010 to Mar 2016,the results were evaluated by comparing preoperative and postoperative audiometric outcomes and the rate of postoperative complications.RESULTS 8 cases with complex lesion combining incus and stapes were found intraoperatively,the deformity located on stapes was showed in one case.The mean postoperative air conduction (AC) value was (26.53 ± 12.28) dB,the mean postoperative air-bone gap (ABG) was (9.44 ± 9.62) dB,the postoperative AC and ABG value improved considerably comparing with the preoperative value in all the patients,the difference was statistically significant.CONCLUTION CO2 laser is a suitable and effective adjunct in surgery for ossicular malformations such as otosclerosis.The use of the laser improves hearing results and operation efficiency and is not likely to increase side-effects to patients.
