Temporal fossa hollowing can represent a serious cosmetic concern to patients after post-traumatic surgery, oncological resection, or surgical dissection for obtaining access to the temporal area. Various methods have been described to augment temporal fossa hollowing, such as use of autogenous bone and cartilage implants, high-density polyethylene implants, and dermal fat grafts. We report a case of 22-year-old man with temporal fossa hollowing after post-traumatic surgery, including temporal muscle resection, whose defect was augmented by using titanium mesh even though long after cranioplasty.
