Abstract

Aim: To assess the complication rate while using abdominal fat, autogenous bone graft and hydroxyapatite cement (each separately) in obliteration of the frontal sinus (FS) after trauma.

Patients and Methods: This study included 11 patients who is indicated for FS obliteration after frontal bone trauma, patients were categorized into 3 groups according to the intended material to be used for FS obliteration; group I (Autogenous fat group) consisted of 4 patients where the FS is obliterated with freshly harvested autogenous abdominal fat, while group II consisted of 4 patients and the sinus is obliterated with autogenous bone (bone group), while group III (hydroxyapatite group) consisted of 3 patients where the FS is obliterated 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, HA cement has the advantages of absence of donor site morbidity and the potential to reconstruct the anterior table, however with an additional cost compared with autogenous grafts.
