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...

Ectopic thoracic kidney is an extremely rare condition caused by the abnormal location of one or both kidneys in the thoracic cavity. They are usually discovered incidentally on routine imaging. Although commonly asymptomatic, thoracic kidneys are at a risk of malrotation, pelviureteric junction obstruction, and subsequent obstructive nephropathy, by virtue of their long pedicle. We present a case report of an incidental thoracic kidney, for which a (99m)technetium-mercaptoacetyltriglycine ((99m)Tc-MAG3) renogram was performed to assess the baseline renal function...

PURPOSE: Subchondral perfusion of osteochondral grafts has been shown to be important in preventing long-term cartilage degeneration. In carpal reconstruction, subchondral perfusion from the graft bed is limited. This study's purpose was to compare the histological characteristics of cartilage in osteochondral grafts supported by synovial imbibition alone to cartilage of vascularized osteochondral flaps that have both synovial and vascular pedicle perfusion. METHODS: Two adjacent osteochondral segments were harvested on the medial femoral trochlea in domestic 6- to 8-month-old pigs...

INTRODUCTION: The management of finger deep burns is still problematic for the surgeon. Due to the fineness and the thickness of the subcutaneous tissue, after excision there is an important risk of exposure of the underlying tissue like bone, nerve or tendons. Local flaps (random pattern flap and pedicle flap) allowed ensuring a good quality covering with a tissue with many advantages (good thickness, sensitivity). On the contrary of all other techniques, flaps can be used independently from the vascular quality of the wound bed...

REVIEW
Shutao Gao, Zhengtao Lv, Huang Fang
PURPOSE: Several studies have revealed that robot-assisted technique might improve the pedicle screw insertion accuracy, but owing to the limited sample sizes in the individual study reported up to now, whether or not robot-assisted technique is superior to conventional freehand technique is indefinite. Thus, we performed this systematic review and meta-analysis based on randomized controlled trials to assess which approach is better. METHODS: Electronic databases including PubMed, EMBASE, CENTRAL, ISI Web of Science, CNKI and WanFang were systematically searched to identify potentially eligible articles...

BACKGROUND: Spinal extradural arachnoid cysts (SEAC) are relatively uncommon. However, several large cysts have presented with spinal cord compression requiring surgical intervention. CASE DESCRIPTION: We report a patient with progressively enlarging SEAC causing worsening right S1 radiculopathy and gastrocnemius muscle atrophy. Electromyography (EMG) and nerve conduction studies (NCS) revealed an S1 motor radiculopathy. Serial magnetic resonance imaging (MRI) findings confirmed enlargement of the small cyst originating from the sacral thecal sac on the right while two smaller cyst on the left remained stable...

BACKGROUND: The "gold standard" for instrumentation of unstable thoracolumbar fracture-dislocations is pedicle screw and rod fixation. Although traditional treatment supports long-segment posterior fixation (LSPF), more recent studies show short-segment posterior fixation (SSPF) may be effective, but incur higher failure rates. Here, we evaluated the effectiveness of SSPF in the management of unstable thoracolumbar injuries and analyzed the factors impacting long-term outcomes. METHODS: In this retrospective analysis of 91 patients with thoracolumbar fractures managed with SSPF alone, we assessed the clinical and radiological parameters at preoperative, postoperative, and follow-up intervals along with reasons for failures of SSPF...

Gingival recession is defined as an apical displacement of the gingival margin beyond the cementoenamel junction leading to serious consequences, including exposure of the root surface, loss of periodontal attachment, root sensitivity to hot and cold air, and esthetic problems. The aim of this study was to evaluate the long-term effect of pedicled buccal fat pad (PBFP) alone and with Emdogain in covering severe gingival recession defects and restoring tooth function. A total of 10 severe buccal recession defects in maxillary first molars were selected to be treated with PBFP, with Emdogain (group I; n = 5) or alone (group II; n = 5)...

Well-vascularized composite tissue offers improved outcomes for complex head and neck reconstruction. Patients with vessel-depleted necks and failed reconstructions require alternative reconstructive options. We describe a pedicled internal mammary artery osteomyocutaneous chimeric flap (PIMOC) for salvage head and neck reconstruction. Bilateral dissections of 35 fresh cadavers were performed to study individual tissue components and vascular pedicles to develop the PIMOC technique. The flap was then utilized in a series of patients with vessel-depleted neck anatomy...

Treatment options for simple renal cyst (SRC) include open surgery, laparoscopy with decortication, or percutaneous aspiration with or without sclerotherapy. Though laparoscopic unroofing achieves better results than percutaneous sclerotherapy, the reported recurrence rate is still up to 19%. Thus, it is necessary to find methods to reduce the recurrence rate.To investigate whether the perirenal pedicled fat tissue wadding technique during retroperitoneal laproscopic deroofing (RLD) of SRC affects the incidence of recurrence...
