[Chondro-perichondrial connections in otic surgery (CPC)]

Tympanoplasty does not resolve problems such as tympanic reconstruction, pneumatic cavity and ossicular transmission mechanism. With the purpose to solve these problems, we used autografts of tragal cartilage with its perichondrial membrane. In just one surgical procedure, we built a transmission mechanism and a consistent new tympanic membrane. Results obtained after 2 years of experience are very encouraging, since postoperative auditive function improves up to 75%; also, a good pneumatic cavity and a well vascularized new tympanic membrane are achieved. Reabsorption of the cartilage was not seen in any case.
