Abstract

Abstract : Abstract: Large skull defects can result in chronic injury to intracranial tissues as well as psychological trauma for patients, and their repair presents a challenge to surgeons. Hydroxyapatite has been used in reconstructing skull defects for many years, but it is difficult to adjust the shape and size of the material intraoperatively, especially for large defects. With three-dimensional digital technology, a new type of customized composite implant made of epoxide acrylate maleic and hydroxyapatite has been applied in clinical practice. In this retrospective review, 15 patients with large skull defects (4 female and 11 male, at a mean age of 36.4 years, range from 24–65 years) were treated with the novel customized composite implant, reconstructing the large skull defects successfully. During the average 2.2 years follow-up period (range 0.5–4 years), complications including infection, cerebrospinal fluid leakage, intracranial hemorrhage, or implant exposurea were not occured, only 1 patient (6.7%) with a seroma managed non-operatively. The customized implants, which required no intraoperative adjustments and are about a third of the cost of titanium implants, are an excellent alternative for large skull defect repair.
