We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired...

REVIEW
Demetri Arnaoutakis, Sameep Kadakia, Manoj Abraham, Thomas Lee, Yadranko Ducic
The goals of reconstruction following any oncologic extirpation are preservation of function, restoration of cosmesis, and avoidance of morbidity. Anatomically, the lateral skull base is complex and conceptually intricate due to its three-dimensional morphology. The temporal bone articulates with five other cranial bones and forms many sutures and foramina through which pass critical neural and vascular structures. Remnant defects following resection of lateral skull base tumors are often not amenable to primary closure...

BACKGROUND: Frontofacial monobloc advancement (FFMBA) creates a communication between the anterior cranial fossa and nasal cavities. To tackle this issue, trans-orbital pericranial pedicled flaps (PF) are routinely performed in our center. This study aimed to assess the post-operative ossification of the anterior skull base and PF following FFMBA, and to identify factors influencing this ossification. METHODS: Measurements of the skull base only (SB) and of the ossified PF together with the SB (SB-OPF) were performed on CT scans at the naso-frontal (NF) and the naso-ethmoïdo-frontal (NEF) junctions...

BACKGROUND: Neuromodulation devices have the potential to transform modern day treatments for patients with medicine-resistant neurological disease. For instance, the NeuroPace System (NeuroPace Inc, Mountain View, California) is a Food and Drug Administration (FDA)-approved device developed for closed-loop direct brain neurostimulation in the setting of drug-resistant focal epilepsy. However, current methods require placement either above or below the skull in nonanatomic locations. This type of positioning has several drawbacks including visible deformities and scalp pressure from underneath leading to eventual wound healing difficulties, micromotion of hardware with infection, and extrusion leading to premature explantation...

Defect reconstruction of the trunk can be performed using microsurgical free flap transplantation. In cases of missing or inappropriate recipient vessels, microsurgical defect reconstruction of the trunk can be achieved by combining free flaps with arteriovenous loops. Here we present our 5-year experience of trunk reconstruction using AV loops and free flaps in a retrospective evaluation. We analyzed 32 cases of trunk reconstruction using a combined approach of free flap transplantation and arteriovenous loops between 2011 and 2016 regarding postoperative complications and perioperative course...

BACKGROUND: Scalp defects can be reconstructed either with skin graft, local flaps, free flaps, or tissue expansion. Tissue expanders have been proved to be fruitful in the pediatric population. Scalp expansion has proved to be useful in the reconstruction of posttraumatic and postburn alopecic defects. Selective nerve block can be added for attenuation of sympathetic stimulation and decrease surgical stress in cranial surgeries. In this study, a comparison was done between using selective nerve block and without selective nerve block in both stages of tissue expansion procedure...
