" Together, the cheek and neck can be considered as single anatomic location because skin vascularity, texture and thickness are similar. The cervicofacial flap has been described as the treatment of choice for the cheek defect because of its good mobility and excellent cosmetic result. However, if the defects on the cheek are wider than the length of palpebral fissure or extended to the lower two thirds of the cheek, the conventional cevicofacial flaps would be inadequate in size without the benefit of expansion.
 Tissue expansion of the cheek and neck is distinguished by a particularly high rate of complication. Prevention of various complications require careful planning and certain modifications in technique.
 We have used the following modifications and measures to prevent the complications and to maximize the expansion.
 1) Whenever possible, expanders were placed over the rigid foundation such as mandible or posterior neck area after wide undermining.
 2) Expanders were placed deep to platysma in the neck area.
 3) Following optimal expansion, the further dissection extending to the clavicle and the posterior neck area was performed for optimal mobilization and draping of the expanded skin.
4) The expanded skin was advanced upward on the cervical portion and rotated forward on the cheek portion.
5) The flap should not be draped above the inferior orbital rim and postoperatively the pressure garments were applied to prevent drooping of the expanded skin.
We experienced 21 cases of the expanded cervicofacial flaps with above surgical modifications and the expanded cervicofacial flaps can resurface the 95% of cheek defects with minimal complications and excellent cosmetic results.
