The tolerance of bio-inert aluminium oxide ceramic as a PORP or TORP design has been studied histologically and clinically. Thirty-five patients had an aluminium oxide prosthesis implanted into the middle ear. There was a hearing gain of 21 dB in the speech frequencies. Patients were monitored for an average period of 20 months (3/4-2 1/4 years); the shortest period was 9 months, the longest 27. The functional results were satisfactory. The acoustic efficiency between 0-20 dB air-bone gap was not greater than with human ossicles or cartilage, although there was no fixation or resorption and a better structural stability.
生物惰性氧化铝陶瓷作为部分听骨赝复物（PORP）或全听骨赝复物（TORP）设计的耐受性已进行了组织学和临床研究。35例患者中耳植入了氧化铝假体。言语频率听力增益为21分贝。患者平均监测期为20个月（3/4 - 2 1/4年）；最短9个月，最长27个月。功能结果令人满意。尽管没有固定或吸收且结构稳定性更好，但在0 - 20分贝气骨导差之间的声学效率并不比人听小骨或软骨更高。
