Comparison for the complication rate with three different materials used in frontal sinus obliteration

Abstract

Aim:The aim of the current study was to evaluate the complications rate after frontal sinus obliteration following trauma with the use of each one of the following graft materials separately; abdominal fat, autogenic iliac bone, or hydroxyappaite cement.Patients and Methods: This study included 11 patients who is indicated for FS obliteration after frontal bone trauma, patients were divided into three groups according to the intended material to be used in FS obliteration; group I (Autogenous fat group) included four patients where the FS is obliterated with freshly harvested autogenous abdominal fat, group II included four patients and the sinus is obliterated with autogenous bone (bone group), while group III (hydroxyapatite group) included three patients where FS obliteration done with hydroxyapatite (HA) cement.Results: All the used materials for FS obliteration showed comparable results with high success rate and low rate of complications with no significant differences between them, most of the complications that happen were transient and were categorized as minimum to moderate. Conclusion:Autogenous fat, HA cement and autogenous cancellous bone are perfect materials to obliterate the FS. The benefits of HA cement include the lack of donor site morbidity and the ability to reconstruct the anterior table, however with an additional cost compared with autogenous grafts.
