Comparison of fast-setting calcium phosphate bone cement and fat autograft in a rabbit model of frontal sinus obliteration.

Background: Traditionally, chronic obstruction of the frontal recess is managed by frontal sinus obliteration (FSO). This often requires the harvest of abdominal fat as a filler with all of its associated morbidity. In this study, we investigate the efficacy of calcium phosphate bone cement (Craniofacial Repair System [CRS]) as a material for FSO.

Demineralized bone matrix and fat autograft in a rabbit model of frontal sinus obliteration.

Objective: In this study, we investigate the efficacy of demineralized bone matrix (DBM) as a material for frontal sinus obliteration in a rabbit model.

Study Design And Setting: Twenty-four New Zealand White rabbits were divided into four groups, and the study was carried out to two time periods. Twelve rabbits underwent frontal sinus obliteration with fat autograft, and 12 rabbits underwent the procedure with DBM.
