“…While considering the abovementioned results, the results of this study should be compared with caution with those of other studies because of methodological differences in the analysis. The functional results confirm that the presence of an intact stapes superstructure is associated with better hearing results, both pre-and post-operative, a fact that has been noted in many previous studies [1] [7] [13]- [15], unlike what supported by other studies [30]. Moreover, the study emphasizes the importance of functional separation of the two acoustic windows by fascia and cartilage graft when the stapes superstructure is missing but the footplate is mobile.…”

“…Previous studies have compared hearing results between ears in the CWU-M and in CWD-M for comparable ossicular pathology: there were no significant differences in hearing results whether the canal wall was intact or not [7]- [12]. The best hearing results occurred when the ossicular chain was intact and mobile [1] [13] [14].…”

“…The best hearing results occurred when the ossicular chain was intact and mobile [1] [13] [14]. When the ossicular chain was diseased, better results occurred if the stapes was intact [7] [13]- [15]. In CWD-M, stapes columella reconstructions were superior to major columella reconstructions by approximately 5 dB (0.05 at most frequencies) [16].…”

Tympanomastoid surgery for cholesteatoma is a procedure designed to eliminate the disease and maintain a safe and dry ear. This retrospective study was designed to evaluate the functional results of cholesteatoma patients who underwent canal wall down mastoidectomy in conjunction with a tympanoplasty. Operated ears due to chronic otitis media with cholesteatoma were considered for the study. The study was carried out in 120 ears. The choice of technique for tympanoplasty is based on the pathology encountered in the stapes superstructure. Patients were divided into three: 1) Group A, a type II TPL with stapes columella reconstruction; 2) Group B, a type III TPL with major columella reconstruction; and 3) Group C, a type IV TPL using a temporalis fascia and thick cartilage to shield the round window. The operated ears of Groups A and B, as compared to Group C, presented a significant decrease in the pre-operative Air-bone gap and an increase in the number of operated ears with an Air-bone gap between 0 -20 dB. The study emphasizes the importance of functional separation of the two acoustic windows by fascia and cartilage graft when the stapes superstructure is missing but the footplate is mobile.

“…This finding is in contrast to the many reports in the past on the light microscopic appearances of Proplast and Plastipore prostheses after varying periods in the middle ear. Most of these have referred to the presence of foreign body giant cells and macrophages representing rejection of the prosthesis [13][14][15][16][17]. In these studies, however, the prostheses were completely made of polyethylene, including the head of the prostheses.…”

“…Polyethylene is easy to trim and to use intraoperatively. Polyethylene behaves as a biocompatible material, however, when in contact with the tympanic membrane, the material becomes surrounded by macrophages and foreign body giant cells Meijer/Segenhout/Albers/van de Want representing rejection [13][14][15][16][17][18]. To combine the properties of biocompatibility and manipulation, a homogeneous material consisting of 40% hydroxylapatite and 60% polyethylene was introduced (HAPEX, Smith and Nephew).…”

The biocompatibility of hydroxylapatite-polyethylene composite implants (HAPEX, Smith and Nephew) was investigated in this study. Eleven middle ear prostheses, removed during revision surgery, have been examined by light microscopy, transmission electron microscopy and scanning electron microscopy. The results show that the middle ear prostheses become overgrown by fibrous tissue inside a thin epithelial layer. In some cases the prosthesis is covered by fibrous tissue without an outer layer of epithelial cells. No arguments have been found for the accumulation of macrophages and foreign body giant cells associated with a foreign body reaction to the material. Therefore, hydroxylapatite-polyethylene composite implants (HAPEX, Smith and Nephew) would seem to be very suitable for reconstructive middle ear surgery.

\s=b\Ossicular reconstruction was performed in 102 ears using homologous, costochondral cartilage. The cartilage was presculpted into a total ossicular replacement or partial ossicular replacement configuration by a tissue bank and stored for later use. The preformed transplants were further shaped in the operating room to suit the anatomical findings during tympanoplasty. The postoperative hearing results as determined by the airbone gap were comparable with those obtained with alloplastic materials (mean gap, 18.6 dB). No extrusions occurred; an analysis of hearing after three years showed that 96.7% of the initial hearing improvement was maintained in 51 ears available for study. Homologous cartilage in the total ossicular replacement or partial ossicular replacement configuration is as effective as alloplastic materials in ossicular reconstruction and it does not resorb or extrude with time.
