Surgical pitfalls with custom-made porous hydroxyapatite cranial implants

Aim: Cranioplasty implants are used primarily in cases of surgical cranial decompression following pathological elevations of intracranial pressure. Available bone substitutes include porous hydroxyapatite (HA) and polymethylmethacrylate. Whichever material is used, however, prosthetic cranial implants are susceptible to intraand postsurgical complications and even failure. The aim of this stud...

Custom-fit radiolucent cranial implants for neurophysiological recording and stimulation.

BACKGROUND Recording and manipulating neural activity in awake behaving animal models requires long-term implantation of cranial implants that must address a variety of design considerations, which include preventing infection, minimizing tissue damage, mechanical strength of the implant, and MRI compatibility. NEW METHOD Here we address these issues by designing legless, custom-fit cranial i...

Use of “custom made” porous hydroxyapatite implants for cranioplasty: postoperative analysis of complications in 1549 patients

BACKGROUND Cranioplasty is a surgical intervention aimed at reestablishing the integrity of skull defects, and should be considered the conclusion of a surgical act that began with bone flap removal. Autologous bone is still considered the treatment of choice for cranioplasty. An alternative choice is bioceramic porous hydroxyapatite (HA) as it is one of the materials that meets and comes close...

Cranial Reconstruction in a Pediatric Patient Using a Tissue Expander and Custom-made Hydroxyapatite Implant.

A tissue expansion technique in conjunction with a custom-made artificial bone implant was effective for a large cranial reconstruction in a pediatric patient. The patient was an eight-year-old boy with cranial bone fracture, acute subdural hematoma in the left lobe, and acute epidural hematoma in the right lobe due to an accident. Wound dehiscence and artificial dura infection were observed as...
