Hemispheric brain volume replacement with free latissimus dorsi flap as first step in skull reconstruction

Outcomes and Utility of Intracranial Free Tissue Transfer

OBJECTIVE

Complications associated with intracranial vault compromise can be neurologically and systemically devastating. Primary and secondary repair of these deficits require an air and watertight barrier between the intracranial and extracranial environments. This study evaluated the outcomes and utility of using intracranial free tissue transfer as both primary and salvage surgical repair of reconstruction.

METHODS

A retrospective review was performed of all subjects who underwent intracranial free tissue transfer as primary or salvage repair.

RESULTS

A total of 13 intracranial free tissue transfers were performed on 11 subjects: osteocutaneous radial forearm free flaps (n = 6), partial myofascial rectus abdominis flaps (n = 5), temporoparietal fascia flap (n = 1), and serratus anterior myofascial flap (n = 1). Primary reconstruction was performed on 4 subjects with the remaining being salvage repair. Indications for surgery included neoplasm (n = 6 of 11), ballistic trauma (n = 3 of 11), motor vehicle accident (n = 1 of 11), and infection (n = 1 of 11). Three subjects required additional surgical repair for CSF leak and pneumocephalus, with 2 subjects requiring an additional free tissue transfer at a different site.

CONCLUSION

In our experience, free tissue transfer is an effective primary and salvage surgical technique in the reconstruction of complex intracranial problems.

Case Report: Free Latissimus Dorsi Flap in Combination With Subdural Space Reduction for the Prevention of Recurrent Hemorrhage Following Hemispherectomy

BACKGROUND AND IMPORTANCE

Extensive cerebral resections for the treatment of epilepsy may result in a large intracranial dead space that is prone to recurrent hemorrhage, either due to mechanical dislodgement or the development of extensive subdural membranes. Several techniques have been proposed to decrease the risk of hemorrhage by either reducing or filling the remaining intracranial dead space.

CLINICAL PRESENTATION

We present a case of persistent hemorrhage following functional hemispherectomy in a patient with a large porencephalic cyst. A treatment strategy involving both subdural space reduction and cranial vault filling with a vascularized free latissimus dorsi flap is discussed.

CONCLUSION

Subdural space reduction and cranial vault filling with a vascularized free latissimus dorsi flap is a viable treatment alternative in patients with large areas of intracranial dead space.

Multidisciplinary approach for reconstruction of cranial defect with polymethyl methacrylate resin reinforced with titanium mesh

Cranial defects occur most commonly as a sequelae to trauma, the incidence being as high as 70%. The successful management of a case of trauma in an emergency situation requires quick evacuation of the hematoma, repair of the dura, and the scalp but not necessarily the integrity of the calvarial segment as an immediate measure. So the reconstruction of the calvarial defect in these cases is mostly carried out as a secondary procedure. Various materials are used for reconstruction of cranial defects, polymethyl methacrylate (PMMA) resin being one of them. In this article, we report a case which was successfully treated by PMMA resin in combination with a titanium mesh for reconstruction of the cranial defect as a secondary procedure.

Reconstruction of a large complex skull defect in a child: a case report and literature review

BACKGROUND

Major skull defects, especially in the anterior region, can present as a most disturbing deformity. Reconstructive cranioplasty can restore cerebral protection and improve craniofacial aesthetics. Complex and large skull defects in children often present reconstructive difficulties.

MATERIALS AND METHODS

In this paper, an unusual case of a very large post-traumatic defect (318 cm(2)) in a child managed by a multidisciplinary team is described. The literature is reviewed.

CONCLUSION

The management of a large complex skull defect in children is still controversial. Each case should be extensively debated in craniofacial units. In our case, bioceramics proved to be an effective and good alternative for final skull reconstruction.
