The modified DCB represents an excellent partial ossicular replacement prosthesis. The perichondrium layer left attached on the cartilage surface in contact with tympanic membrane increases the stability of DCB and prevents the displacement and the loss of stiffness of the cartilage. The modified DCB ossiculoplasty is easy to perform. Hearing results are satisfactory and lasting. The cost is null, and the tolerance is excellent.

“…12,[18][19][20] Vascularization of cartilage can also lead to calcification of the matrix, rather than resorption, and has been reported previously. 12,13,19,21 Our observations from this small number of specimens suggest that cartilage struts are likely to be suboptimal for reconstruction of the sound transmission system, although they are probably satisfactory as buffers between a synthetic prosthesis and ORP -ossicular replacement prosthesis; TORP -total ossicular replacement prosthesis; PORP -partial ossicular replacement prosthesis; AB -air-bone; COM -chronic otitis media. *--None; + -occasional; ++ -cells in peripheral areas only; +++ -cells in majority of ORP; ++++ -cells throughout ORP or extreme cellular infiltration.…”

Autogenous malleus, incus, and cortical bone grafts behaved in a similar manner and maintained their morphological size, shape, and contour for extended periods of time, at least up to 30 years. These histopathologic observations support the continued use of autograft ossicular and cortical bone grafts for middle ear reconstruction. Cartilage grafts developed chondromalacia with resulting loss of stiffness and showed a tendency to undergo resorption. Synthetic prostheses made of porous plastic (Plastipore, Polycel) elicited foreign body giant cell reactions with various degrees of biodegradation of the implants. Prostheses made of hydroxyapatite and Bioglass were enveloped by a lining of connective tissue and mucosal epithelium. The Bioglass material was broken down into small fragments and partially resorbed by a host response within the middle ear. These results warrant caution in the use of prostheses made of porous plastic or Bioglass.

“…Heermann selbst nutzte den Knorpel auch für den Ossikelersatz. Da das histologische Langzeitverhalten von Knorpel als Ossikelersatz jedoch unsicher ist [13], haben wir uns für den Einsatz von Titanprothesen entschieden. Im Gegensatz zu der von Heermann empfohlenen Anulus-Stapes-Platte [4], die eine Brücke vom Limbus zum Steigbügelköpfchen bildet, wird die Pauke bei Verwendung einer Partialprothese höher und folglich das Offenhalten der tubofenestralen Belüftungsstraße gewährleistet.…”

The low rate of recurrent tympanic membrane defects (2.4%) shows that palisade cartilage tympanoplasty is particularly appropriate for the management of difficult indications in middle ear surgery. Further, it could be demonstrated that the PCT can be combined safely with titanium ossicular reconstruction prostheses. Regarding postoperative hearing results the negative preselection of pathological conditions has to be considered.
