BACKGROUND: The list of complications reported after decompressive craniectomy (DC) and cranioplasty is progressively increasing. Nonetheless, the exact incidence of these events is still ill-defined. Problems affecting skin flaps after DC and cranioplasty have never been accurately analyzed in papers and their impact on patients' prognosis is largely underestimated. METHODS: In a 10-year time, we treated by DC 450 patients, 344 of whom underwent cranioplasty, either with autologous bone or artificial implants (hydroxyapatite, polyetheretherketone, titanium, polymethylmethacrylate)...

Goktekin Tenekeci, Yavuz Basterzi
Reconstruction of large myelomeningocele defects using extended (elongated beyond the lateral margin of the latissimus dorsi muscle) dorsal intercostal artery perforator (DICAP) propeller flaps is not recommended by previous studies. However, to provide tension-free and successful closure of a defect, the DICAP propeller flaps must sometimes be elongated beyond this margin. Our experience and results in this issue are discussed. In this article, reconstruction of 11 consecutive cases, with large myelomeningocele defects in which standard DICAP propeller flaps were incapable to close the defect, was achieved using extended DICAP propeller flaps between June 2013 and November 2015...

BACKGROUND: Maxillary artery has traditionally been considered the main blood supply of the facial skeleton. However, the deep and concealed location makes the harvest of facial allografts based on this artery challenging, giving preference to the facial artery. There is growing evidence that the junction between the hard and soft palate may represent a watershed area in facial artery based allografts. The aim of this study was to review the occurrence of partial allograft necrosis and modify the available craniofacial techniques allowing for a reliable harvest of maxillary artery based facial allografts...

INTRODUCTION: Numerous causalities including attempts of penile augmentation with silicone or paraffin can lead to extensive circular penile shaft defects. Reconstruction is challenging and skin grafting is a suboptimal option, despite its widespread use. This paper presents a surgical technique for penile shaft reconstruction with bipedicled anterior scrotal flap. PATIENTS AND METHODS: Retrospective data analysis was performed for patients treated for symptomatic penile siliconomas who underwent subsequent penile reconstruction with bipedicled anterior scrotal flap between 2010 and 2015...

In head and neck reconstruction using free flaps, microvascular anastomosis is commonly performed in an end-to-end fashion to relatively sizable arteries including the superficial temporal, facial, and superior thyroid arteries. With the recent developments of less invasive perforator flaps such as the superficial circumflex iliac artery perforator flap, anastomosis of smaller vessels of less than 0.8 mm diameter has become necessary; however, appropriate recipient arteries for end-to-end anastomosis are often absent...

Large avulsed skin flaps of the lower extremity caused by degloving injuries eventually develop skin necrosis in most cases. The current treatment option involves excision of the degloved skin and reapplication as a full- or split-thickness skin graft. We considered that reattachment of avulsed skin flaps without excision would be theoretically beneficial, since some circulation may remain around the connected pedicle and thus facilitate graft take. Furthermore, securing the skin to the original anatomic position is much easier using retained landmarks...
