title: Bone replacement by ionomer cement in osteoplastic frontal sinus operations.
abstract: Ionomer-based cement is a new bone replacement material. After promising results in middle ear and skull base surgery, we started to use Ionocap as an alternative to metal osteosynthesis material. Between 1992 and 1995, 20 men and 9 women were treated with an osteoplastic approach for complicated frontal sinus diseases at Johann Wolfgang Goethe University. Ionocap as bonding material for bone was used in 22 of the patients. The indications for osteoplastic surgery were recurrent frontal rhinosinusitis, mucoceles, skull base fractures, osteomas and meningocele. The surgical procedure using bone cement was found to be much easier and shorter, the functional stability achieved was at least equal and the cosmetic outcome was clearly superior when compared to cases done with metal osteosynthesis. No rejection of the material or osteonecrosis was observed. In no case was the cement placed in direct contact to dura mater. Our findings show that ionomer-based cement can be recommened in osteoplastic frontal sinus surgery, but Ionocap should only be used strictly according to the guidelines of the supplier.
