Abstract

Hearing results and causes of failure with three types of ossicular reconstruction techniques over an intact stapes, during second-stage intact canal wall tympanoplasty, are reported herein. The three types of reconstruction are: fitted autologous incus (38 cases); Plastipore PORP with cartilage (41 cases); Plastipore PORP without cartilage (32 cases). A residual air-bone gap within 15 dB. was found in 63.2 per cent of fitted includes, in 41.5 per cent of PORPs with cartilage, and in only 37 per cent of PORPs without cartilage. Eighty-four per cent fitted incudes, 63 per cent PORPs with cartilage and 44 per cent PORPs without cartilage yielded a residual air-bone gap within 25 dB. Extrusion has been the main cause of failure among Plastipore prostheses.

摘要

本文报告了在二期完整外耳道壁鼓室成形术中，三种类型的听骨链重建技术在镫骨完整情况下的听力结果及失败原因。三种重建类型分别为：自体砧骨适配（38例）；带软骨的Plastipore PORP（41例）；不带软骨的Plastipore PORP（32例）。在适配砧骨组中，63.2%的患者气骨导差在15 dB以内；带软骨的PORP组为41.5%；不带软骨的PORP组仅为37%。84%的适配砧骨、63%带软骨的PORP以及44%不带软骨的PORP患者气骨导差在25 dB以内。假体脱出是Plastipore假体失败的主要原因。
