“…The rate of absorption increases over the time from 1.6 % after 2 years [17], to 5.1 % after 3 [19] and 36 % after more than 6 years [18]. Extrusion rates were reported to be as high as 8 % [20]. As a consequence, Ceravital TM was withdrawn from the market.…”

This review gives a survey of biomaterials used for ossicular chain reconstruction. The survey is focussed on application, biophysical requirements, properties and goals for future developments. The implantation site middle ear differs from others due to aeration and potential bacterial colonization. As a consequence, implant materials must exhibit excellent biocompatibility, biostabilty and sound conducting properties. In vitro and in vivo biocompatibility investigations and clinical observations determine the choice of material. Additionally the implants must provide the possibilty of intraoperative shaping or should be available in different variations in order to allow reconstruction appropriate to the individual conditions. Ceramics, metals and plastics are materials in current use. Based on thorough experimental and long term clinical experiences, the bioinert aluminum oxide is favorable amoung the ceramics. Bioactive ceramics may have minor biostability and the risk of fixation to surrounding bone which impairs sound conduction. This is also true for hydroxyapatite although biodegradation occurs only rarely. Today, titanium is the metal best established in middle ear implantation, reflected by excellent biocompatibility in vitro and in vivo, and good clinical results. Titanium is preferred by many surgeons, considering that sound transmission properties are mainly dependent on the implant weight. In stapes surgery, when the implant has direct contact to inner fluids, gold was accused to cause granuloma formation with subsequent inner ear damage in selected cases. In frequent past and present use, plastics (porous polyethylene and teflon) have proven to be of limited value in ossicular chain replacement because of high extrusion rates and the observation of material desintegration and bacterial colonization. In order to individually manage the pathological conditions in the middle ear, the implant design is of crucial importance. It is dependent on the ossicle to be replaced and the implant material. Future investigations have to minimize implant extrusions possibly by modifying and improving implant surfaces.

The interface between ionomer cement and bone in the porcine cervical spine

et al. 1996

View full text Add to dashboard Cite

The interface between bone and ionomer cement has been studied in twelve young adult pigs 1-6 months after anterior cervical discectomy, removal of adjacent end plates and grafting of the bone defect with ionomer cement. Methods used to study the interface were fluorescence microscopy, scanning electron microscopy, electron microprobe analysis and radiological investigation. The interface in all animals consisted of collagenous tissue. The amount of collagenous fibres was related to the amount of residual movement within the motion segment: animals undergoing anterior plating after reconstruction of the bone defect presented with more or less compactly organized collagenous tissue. Sequential fluorochromic marking of osteoid formation revealed a vital bone bed around the interface but no signs of direct bone apposition to the ionomer cement plug. No signs of toxicity or graft rejection were noted. Ionomer bone cement contrary to experimental and clinical experience induces the formation of a connective tissue layer of different density in the porcine cervical spine.

“…The mixture of fluoro-aluminium silicate glass powder and solvent results in a whitish, paste-like material that adheres well to bone and hardens within a few minutes. In recent years, the potential use of GIBC in otorhinolaryngology has been explored and preliminary experience in otology has been described [7,8] .…”

OBJECTIVE:To assess the effectiveness of glass ionomer bone cement (GIBC) in lateral attic wall reconstruction after primary acquired attic cholesteatoma surgery. MATERIALS and METHODS:This prospective study was conducted on twenty children collected from the ENT outpatient clinics of a secondary and tertiary hospital. All patients presented with chronic suppurative otitis media with cholesteatoma of the primary acquired attic type. All patients underwent intact canal wall mastoidectomy (ICWM) with a transcanal atticotomy to address primary cholesteatoma involving the attic and the supratubal recess. Removal of the incus with or without decapitation of the malleus depended on the extension of the pathology. GIBC was used to build up the lateral attic wall in all cases. Ossiculoplasty and tympanoplasty were performed according to the extent of disease. RESULTS:All patients had integrated skin covering the reconstructed attic wall with no signs of granulation tissue formation, canal wall edema, glass ionomer extrusion, or foreign body reaction on the 6 th month, 1 st year and 2 nd year follow-up visits. Also, no persistent otorrhea was noted. The postoperative air-bone gap was significantly improved (p=0.007).CONCLUSION: GIBC could be considered as a reliable artificial material for reconstruction of the lateral attic wall after transmeatal atticotomy in ICWM, making it feasible to avoid cavity problems of canal wall down mastoidectomy, especially in children. KEYWORDS: MATERIALS and METHODSThis prospective study was conducted on twenty children presenting at the Otorhinolaryngology Outpatient Clinics of a secondary and tertiary referral hospital over a 2-year period, from April 2012 to April 2014, with primary acquired attic cholesteatoma of variable extensions to the middle ear and mastoid cavity. These patients were selected from a total of 180 chronic suppurative otitis media (CSOM) patients presenting in this period of time. Ethical ConsiderationsThe Ethical Committee of the School of Medicine approved the protocol of the study before it began; all patient parents provided written consent before participating in the study. Surgical TechniqueThe patients were subjected to preoperative evaluation, including preoperative oto-endoscopic examination, preoperative pure tone audiometry (PTA), radiological assessment, and explanation of the surgery to patient guardians.The procedure was carried out under general anesthesia in the form of ICWM through a post-auricular approach. A transcanal atticotomy was performed in all cases to ensure complete access to the anterior attic and supratubal recess area. Removal of the incus and excision of the malleus head were performed according to the extent of disease. Total clearance of cholesteatoma and granulations from the attic, antrum, and middle ear, including the sinus tympani area and supratubal recess were followed. The lateral attic wall was reconstructed with GIBC. Reconstruction of the ossicular chain depended on the degree of its involvement in the form of either inc...
