Abstract
The aim of this study was to evaluate the resorption of the iliac bone after maxillary
reconstruction with a vascularized free iliac flap. Twenty-seven patients with maxillary
defects who underwent maxillary reconstruction with the vascularized free iliac flap
between January 2017 and January 2021 were included. Computed tomography (CT) images
taken at 1 week, approximately 6 months, and 1 year after the surgery were used for
evaluation. The total iliac bone thickness and height, cortical bone thickness, and
cancellous bone density were measured in the CT images. Compared with 1 week after
the surgery, the total thickness and height of the iliac bone were reduced significantly
1 year after the surgery, and the cortical bone thickness and cancellous bone density
were reduced significantly at 6 months and 1 year after the surgery. Compared with
6 months after the surgery, cancellous bone density was reduced significantly 1 year
after the surgery. In conclusion, during the first year after maxillary reconstruction
with a vascularized free iliac flap, there was significant resorption of iliac bone,
including the total iliac bone thickness and height, the cortical bone thickness,
and the cancellous bone density.
