Reconstruction of Cranial Defect With Individualized PEEK Implant: Case Report

“…Cranial defects generate functional, aesthetic and psychological alterations that significantly affect the quality of life of patients [5]. The current controversy in reconstruction focuses on identifying the best time to perform it, and on the type of implant (material) to use [1,3].…”

“…Currently, autologous bone grafting is considered the "gold standard" for post-craniotomy reconstruction. However, it is not always possible to use it, since in most cases, these reconstructions are performed in a delayed manner (as in the case presented), compromising the vitality of the graft [5]. Regarding the size of the defect to be reconstructed, the Poukens classification describes small defects (10-50 cm 2 ) which can be reconstructed with autologous bone graft segments or non-personalized titanium meshes.…”

“…Subsequently, the PEEK implant was positioned in the defect, verifying that its adaptation is adequate. Once the final position was confirmed, suspensory sutures were passed through the preformed holes of the prostheses, different studies report infections, post-operative hematomas, fistulas, seromas, dehiscence and problems in the healing of operative wounds [1][2][3][4][5]. The type of material used would not be a risk factor associated with infections, however, it has been seen that the materials with the largest surface have greater resistance to infections, since they allow active support and growth of the tissues towards the interior.…”

“…ics and function, and reducing undesired neurological effects [4,5]. There are several ways to reconstruct these defects [6][7][8][9][10][11][12], and in all of them it is important to evaluate a series of factors, such as the material to be used, the costs, the type of surgical procedure to be performed, its associated morbidity, and its stability in the time [4].…”

“…The current treatment of choice is controversial, and is related to the type of material to be used, since the ideal material for reconstruction of cranial defects does not exist [5], so finding one that improves the prognosis of treatment has been a constant search [3]. With the difficulties associated with the use of autografts, interest in alloplastic materials has grown, and a series of materials that can reduce the complications associated with the use of bone grafts have been analyzed and acrylate, which psychologically affected the patient.…”
