采用3种不同的激光(Er：YAG，Ho：YAG，翠绿宝石)在砧骨长突末端打孔，以固定砧骨切除或小窗骨切除后的假耳。能量被耦合到芯径为250 PM的氟化锆光纤中。手术是在身体的人类颞骨模型上进行的。在立体手术显微镜下将纤维引导至砧骨。扫描电子显微镜下观察组织反应，脱钙后组织学观察。这些研究表明，在听骨链重建术中，使用Er：YAG激光可以改善义齿的支撑力，增加听骨链的稳定性。
Three different lasers (erbium:YAG, holmium:YAG, alexandrite) were used to drill a hole at the end of the long process of the incus in order to fix an ear prosthesis after stapedectomy or small fenestra stapedectomy. The energy was coupled into a 250‐pm core diameter zirconium‐fluoride fiber. The operations were carried out on human temporal bone models from cadavers. The fiber was guided to the incus under the stereoscopic surgical microscope. The tissue response was examined under the scanning electron microscope, and after decalcification, histologi‐cally. These studies suggest the feasibility of using the erbium: YAG laser to improve the anchorage of the prosthesis on the incus and to increase the stability in ossicular chain reconstruction.
