OBJECTIVE: The results of the first cohort of 60 cavity reconstructions with @entity692 with a minimum follow-up period of 15 years were studied. STUDY DESIGN: The study design was a retrospective study. @entity1 : A total of 60 @entity1 had a follow-up period of >15 years. In four @entity1 , not all data were available. Therefore, 56 @entity1 were included in the study. They had a combination of cavity problems and @entity393 . INTERVENTION: The ear canal was reconstructed with a canal wall prosthesis of porous @entity692 . The ossicular chain was reconstructed with an incus or incus-stapes prosthesis of dense @entity692 . RESULTS: After 15 years, 42 @entity1 (75%) had an intact reconstructed ear canal. The main problem for failure was the recurrent purulent @entity2172 and not @entity3540 . The histology of the retrieved canal wall showed a good remodeling in living bone tissue. After 15 years, 34 @entity1 had a normal ear canal and an ossicular chain. Of these @entity1 , 7.05% had an air-bone gap closure within 20 dB. CONCLUSIONS: Long-term results of cavity reconstruction with @entity692 are possible. The main problem is recurrent @entity3137 of the new middle ear-mastoid cleft.
