Complex Frontal Bone Reconstruction Using Computer-designed Polyetheretherketone Implant: Case Report and Literature Review.

Calvarial reconstruction of complex frontal bone defects after head trauma surgery is challenging, especially when it coexists with an absence of eyebrow arch and supraorbital wall. Due to various reasons, the patient's bone flap could not be used. Common alternative materials include polyetheretherketone (PEEK) and titanium. Careful and detailed planning is required to maximize functional and aesthetic reconstruction, thereby benefiting the patient. We present a case of a 36-year-old man who had multiple frontal bone defects after multiple operations for craniofacial fractures performed with reconstruction surgery using a PEEK implant successfully. With a follow-up for 2 years, the patient was satisfied with the long-term aesthetic effect without any consequences such as surrounding tissue infection or implant displacement. The authors believe that the PEEK implant has great potential for calvarial reconstruction due to its incredible strength, durability, and inertness.
