Abstract

Objectives: To assess the efficacy of the hydroxyapatite (HA) cement alone or with simvastatin in obliteration of the frontal sinus after trauma as an alternative to the widely used autologous abdominal fat.
Patients and Methods: 4 out of 9 patients underwent frontal sinus obliteration with autologous abdominal fat (Fat group) and the remaining 5 patients were obliterated with HA cement
(HA group) where 2 patients out of those 5 patients were obliterated with HA alone and the remaining 3 patients of this group were obliterated with HA cement mixed with simvastatin as an osteoinductive material.
Results: Both the autogenous fat and the HA cement has a comparable results; Fat obliteration failed in 1 patient and none of the patients in the HA cement group has acquired any complications that necessitates the material removal, no significant difference in the results obtained from the HA cement when used alone or when mixed with simvastatin.
Conclusion: HA cement is a promising obliterating material in frontal sinus obliteration with comparable results to autogenous fat with the advantages of no donor site morbidity and the potential for complete osseointegration. Addition of simvastatin to the HA cement does not seem to enhance the obtained results.
