Subunits of the cheek: an algorithm for the reconstruction of partial-thickness defects

Reconstruction of partial-thickness defects of the cheek can be challenging. In addition to maintaining function, the repair must restore contour, minimise donor-site deformity and not distort the eyelid, mouth or jaw line. Since the demands for repair differ according to the site, so do the reconstructive options. To aid in selecting the best method, we classify the cheek into five subunits based on vascular anatomy and relevant landmarks. Based on our experience with 160 patients over a 12 year period, we present an algorithm that helps to select the best reconstructive option for each site. This algorithm is easy to follow and conforms to anatomical principles.
