Reconstruction for a mucocele of an old frontal sinus fracture

n the treatment of a mucocele that developed after an old frontal bone fracture, surgically established drainage of the frontal sinus and aesthetic reconstruction are essential. Reconstruction surgery is generally performed by using autologous tissues with abundant blood flow that provides resistance to infection. We treated a mucocele that occurred 23 years after the treatment of a frontal bone fracture, in other words, drainage from the frontal sinus was first established and then reconstruction of the deformity of the forehead by the combination of a free dermal fat graft devoid of blood flow and artificial bone was performed. In the present study, we report that we were able to obtain satisfactory results both functionally and aesthetically.
