Background: Large frontoencephaloceles, more common in low and middle-income countries, require complex reconstruction of cerebral herniation, elongated nose, telecanthus, and cephalic frontal bone rotation. Previously described techniques involve multiple osteotomies, often fail to address cephalad brow rotation, and have high complication rates including up to 35% mortality. This study presents a novel, modified, single-staged technique for frontoencephalocele reconstruction performed by Mercy Ships. This technique, which addresses functional and aesthetic concerns with minimal osteotomies, may help improve outcomes in low resources settings. Methods: Retrospective review was performed of patients who underwent frontoencephalocele reconstruction through Mercy Ships using the technique described. Patient data including country, age, gender, associated diagnoses, and prior interventions were reviewed. Intraoperative and post-operative complications were recorded. Results: Eight patients with frontoencephalocele (ages 4-14 years) underwent surgery with the novel technique in 4 countries. Average surgical time was 6.0 ± 0.9 hours. No intraoperative complications occurred. Post-operatively 1 patient experienced lumbar drain dislodgement requiring replacement and a second had early post-operative fall requiring reoperation for hardware replacement. In person follow-up to 2.4 months showed no additional complications. Follow-up via phone at 1 to 2 years post-op revealed all patients who be satisfied with surgical outcomes. Conclusions: Reconstruction of large frontoencephaloceles can be challenging due to the need for functional closure of the defect and craniofacial reconstruction to correct medial hypertelorism, long nose deformity, and cephalad forehead rotation. The novel surgical technique presented in this paper allows for reliable reconstruction of functional and aesthetic needs with simplified incision design, osteotomies, and bandeau manipulation.

Abstract Background To present a surgical technique for the treatment of intradural extramedullary (IDEM) tumors by using endoscopically controlled surgery with open hemilaminectomy technique. Methods In this study, 20 patients with 22 IDEM tumors were enrolled. An endoscopically controlled surgery with open hemilaminectomy was employed to remove the tumors. Data related to clinical symptoms and medical images before and after surgery were collected for perioperative evaluation and follow-up analysis. Results All the tumors in 20 patients were well removed. The clinical symptoms were significantly reduced in all the patients as well. The short-term follow-up data showed that there was no tumor recurrence or spinal deformity. Conclusion The endoscopically controlled surgery with open hemilaminectomy technique provided favorable exposure and satisfactory resection to the IDEM tumors. It may be an effective surgical method for treating IDEM tumors. Larger samples and longer follow-up data are needed to verify its long-term effectiveness.

OBJECTIVE At present, endoscopic treatment is advised as the first procedure in cases of suprasellar arachnoid cysts (SSCs) with hydrocephalus. However, the appropriate therapy for SSCs without hydrocephalus has not been fully determined yet because such cases are very rare and because it is usually difficult to perform the neuroendoscopic procedure in patients without ventriculomegaly given difficulties with ventricular cannulation and the narrow foramen of Monro. The purpose of this study was to find out the value of navigation-guided neuroendoscopic ventriculocystocisternostomy (VCC) for SSCs without lateral ventriculomegaly. METHODS Five consecutive patients with SSC without hydrocephalus were surgically treated using endoscopic fenestration (VCC) guided by navigation between March 2014 and November 2015. The surgical technique, success rate, and patient outcomes were assessed and compared with those from hydrocephalic patients managed in a similar fashion. RESULTS The small ventricles were successfully cannulated using navigational tracking, and the VCC was accomplished in all patients. There were no operative complications related to the endoscopic procedure. In all patients the SSC decreased in size and symptoms improved postoperatively (mean follow-up 10.4 months). CONCLUSIONS Endoscopic VCC can be performed as an effective, safe, and simple treatment option by using intraoperative image-based neuronavigation in SSC patients without hydrocephalus. The image-guided neuroendoscopic procedure improved the accuracy of the endoscopic approach and minimized brain trauma. The absence of hydrocephalus in patients with SSC may not be a contraindication to endoscopic treatment.

Abstract Purpose The aim of this article is to present an original surgical technique for the treatment of rigid Adult Idiopathic Scoliosis (AdIS) and the results at minimum 2 years follow-up in a cohort of 40 patients. Methods We retrospectively reviewed 40 patients affected by rigid AdIS, older than 40 years and operated with a posterior one stage surgical technique summarized with the acronym Hi-PoAD, (high-density pedicle screws, Ponte osteotomies, asymmetric rods contouring, direct vertebral rotation). The demographic and surgical data were collected, and the improvement of clinical scores and radiologic parameters was obtained after surgery, at 1 and 2 years and at final follow-up, to assess deformity correction, coronal and sagittal balance and clinical outcome. Results The average follow-up was 2.9 years (range 2–3.5). Average coronal Cobb angle decreased from 65.0° ± 8.4 to 18.9° ± 3.9 (p < 0.01). Rotation sagittal angle decreased from 26.2° ± 4.4° to 12.4° ± 2.8° (p < 0.01). Mean thoracic kyphosis improved from 23.1° ± 3.6° to 36.0° ± 3.9°. SRS-22 improved form 2.9 ± 0.4 to 3.7 ± 0.6 (p < 0.01). Four early post-operative deep wound infections were observed, all healed after debridement and implant retention. No mechanical complication, junctional kyphosis, deformity progression or non-union were recorded at the last follow-up. Conclusions Hi-PoAD technique proved to be safe and effective in the treatment of rigid Adult Idiopathic Scoliosis. The reason for the success is related to the combined strategies adopted, that dissipates corrective forces over several levels, reducing mechanical stress at the screw–bone interface and optimizing corrective potential.

Abstract INTRODUCTION Laparoscopic Fundoplication (LF) as a treatment for gastroesophageal reflux disease (GERD) has positive clinical outcomes. However, postoperative dysphagia (PD) may appear as a side effect. Our objective is to analyze PD in patients operated on for LF in our center. MATERIAL AND METHODS Retrospective and descriptive study of patients operated on for GERD from September 1997 to February 2019. RESULTS 248 patients (60.5% men), with a mean age of 49.7 (21-82), were operated. 66.1% of the patients presented associated comorbidities, highlighting obesity (19.8%). 75% manifested typical symptoms, 19% presenting with Barrett’s esophagus. Sliding hiatal, paraesophageal, mixed and complex hernia were diagnosed in 151 (60.9%), 23 (9.3%), 12 (4.8%), and 4 (1.6%) patients, respectively. The LF Nissen was the most frequent technique (91.5%), using a caliper in 46% of the cases. PD was the most frequent symptom, present in 57 (23%) patients. It was resolved with dilation in 9 patients, requiring 6 patients surgical reintervention. In those PD cases, a caliper was used in 28 (49.1%) patients, without finding significant differences between them (P = .586). Nor were there significant differences between PD and obesity (P = .510), type of hiatal hernia (P = .326), or surgical technique (P = .428). After a median follow-up of 50.5 months, quality of life was classified as Visick I-II, III, and IV in 76.6%, 6.9% and 1.2% of the cases, respectively. CONCLUSION No association between PD and the use of calipers, surgical technique or type of hiatal hernia was found in our series.

Object The aim of this study was to describe the surgical technique used for removal of sphenoorbital meningiomas in the authors' practice and to review the operative outcome. Methods Review of the senior author's practice between 1994 and 2009 revealed 39 patients (mean age 48 years) eligible for this study. Clinical presentation, surgical technique, postoperative outcome, and follow-up data are presented. Surgical technique is detailed, with an emphasis on aggressive removal consisting of drilling of the hypertrophied sphenoid bone, orbital wall, and anterior clinoid process, followed by tumor removal and a wide resection of the involved dura. A simple dural closure without reconstruction of the orbital roof or the lateral wall of the orbit is also described. Results Gross-total resection was achieved in 15 cases (38.5%), near-total resection with small residual in the cavernous sinus or periorbita in 20 cases (51.3%), and subtotal resection in 4 cases (10.3%). Postoperative complications included trigeminal hypesthesia in 9 patients, oculomotor palsy in 3 patients, and seizure in 2 patients. Seven patients had recurrence within the mean follow-up period of 40.7 months. Preoperative visual deficits were present in 21 patients (53.8%). Of these, 14 (66.7%) experienced visual recovery to normal levels postoperatively. Statistical analyses revealed preoperative severe visual deficit and sphenoid bone hypertrophy as an independent risk factor and an independent favorable factor, respectively, for a favorable visual outcome. Proptosis was resolved (≤ 2 mm) in 73.5% of the authors' patients. No patient had postoperative enophthalmos. Conclusions In the authors' practice, surgery for sphenoorbital meningiomas consists of resection of the orbital/sphenoid intraosseous, intraorbital, and intradural tumor components. The authors believe that aggressive removal of the orbital/sphenoid intraosseous tumor is critical for a favorable visual outcome and tumor control. Furthermore, satisfactory cosmetic results can be achieved with simple reconstruction techniques as described.

✓ The authors describe the surgical technique of anterior cervical fusion using bone grafts obtained from cervical vertebral bodies. This series consisted of 90 patients with cervical intervertebral disc disease suffering from cervical spondylotic myelopathy. Thirty-five patients were operated on at one level, 33 at two levels, and 22 at three levels. Postoperative x-ray films showed solid bone fusion in all patients at a mean follow-up time of 24 months (range 1 year to 3 years 6 months). Anterior angulation was found in four (4.4%) of the 90 patients. This surgical procedure has two major advantages: 1) there are no complications related to the iliac donor site, allowing early patient mobilization; and 2) the extensive posterior spur can be removed safely and easily under a wide operative field without damaging the spinal cord and nerve roots.
