Classification of cheek carcinomas
From the aesthetic point of view, the cheek region can be divided into three overlapping aesthetic zones including the suborbital (I), the preauricular (II), and the bucco-mandibular (III) zone.9 Anatomically, the cheek consists (from inside to outside) of buccal mucosa, submucosa, loose connective tissue, muscles, the parotid gland in zone II and III, and the skin. Depending on the extent of resection and consequently the depth of defect, patients were dichotomized into patients with partial or through-and-through (full) defects.
