Ionomeric Cement – A Bone Glue for Device Fixation

Abstract

Ionocap®, an ionomeric cement, is a new bone replacement material. Its generic name is polymaleinate ionomer, and it is an inert standardized biomaterial which is offered in a two component system. Since 1988 the ionomeric cement has been evaluated clinically in different situations. Its unique properties of biocompatibility, biostability and permanent adherence to bone make this new material very useful in head and neck surgery.

“…Many clinical and experimental investigations have demonstrated that most GICs are biocompatible, biostable, and well tolerated by bone and soft tissue 2 …”

A musculoperiosteal flap cochlear implant device fixation technique: Our experience in one hundred and seventy nine patients

“…8 Due to the technical difficulties and the possible complications associated with drilling these channels, new techniques using prefabricated anchoring devices or alternative securing materials and methods have been developed. [4][5][6][7] Although successful for device fixation, these materials are costly. As well, foreign materials are being placed on a permanent basis.…”

“…Nine cases of Valsalva manoeuvre induced abnormal air collection after cochlear implantation have been reported in the literature previously. [3][4][5][6][7] Seven cases involved only subcutaneous air; 3,4,7 one case reported only intracranial air; 6 one case described both subcutaneous and intracranial air. 5 Backous et al 3 described two patients who experienced an apparent flap haematoma: one at 8 days and the other at 13 days post-operatively after receiving Clarion â 1.2 and MED-EL (Innsbruck, Austria) Combi 40+ cochlear implant devices, respectively.…”

Device fixation in cochlear implantation: Is bone anchoring necessary?

“…Fixation of the internal receiver/stimulator component of the cochlear implant has traditionally been performed using tie‐down sutures anchored to bone, usually through monocortically drilled channels 2. Multiple permutations on the technique for stabilizing the body of the implant in its desired location are described, including the use of polypropylene sheeting with titanium screws,3, 4 ionomeric bone cement,5 and a specially designed cortical drilling technique to avoid the need for further fixation of any type (for patients >18 months) 6. We describe our results with the periosteal suture technique that has been previously described only in children 1.…”
