REVIEW

Modern glioma surgery has evolved from the principle belief that safe, maximal tumor resection improves symptom management, quality of life, progression-free survival (PFS), and overall survival (OS) in both low- and high-grade glioma (LGG and HGG, respectively). However, in the absence of level I data, the overwhelming support for this idea is derived largely from retrospective series. As a result, the influence of increasing extent of resection (EOR) and reducing tumor burden on the efficacy of postoperative chemotherapy and radiotherapy, and ultimately survival, remains inadequately defined...

In open bite case treatments, a proper diagnostic differentiation is essential in determining the appropriate corrective procedures. Dental open bites are generally more responsive to treatment with orthodontics alone, whereas skeletal open bites often require a combination of orthodontics and orthognathic surgery. Patient selection and treatment principles for non-surgical open bite treatment routinely include fixed appliances both labial or lingual. However, removable clear aligners have gained a consistent popularity in the treatment of complex cases including open bite malocclusions...

Atypical lipomatous tumours (ALT) are rare semi-malignant adipose tissue tumours with the potential to transform into sarcomas. They may occur throughout the body, although the hands are very rarely involved. We present the case of a 49-year-old man with a lipomatous tumour measuring 8×4 cm at the dorsum of the right thumb. MRI demonstrated an inhomogeneous signal after contrast medium application. The tumour was excised in its entirety. Since histology confirmed the diagnosis of an ALT, the thumb was irradiated...

Traumatic amputation of the thumb at the proximal phalanx or the metacarpophalangeal joint can be treated by distraction lengthening depending on the location of the amputation, the patient's age, occupation and functional demands. We report the results of proximal phalanx lengthening in 5 patients using a semicircular ring-type external fixator device. This prototype was developed at our clinic in collaboration with a specialised small company (Rotomed AG, Allmenstrasse 4, CH-4512 Bellach, www.rotomed.ch) based on the principles of Ilizarov's external fixator...

Intralabyrinthine schwannomas (ILS) are a rare differential diagnosis of sudden hearing loss and vertigo. In an own case series of 12 patients, 6 tumors showed an intracochlear, 3 an intravestibular, 1 a transmodiolar including the cerebello-pontine angle (CPA), 1 a transotic including the CPA and 1 a multilocular location. The tumors were removed surgically in 9 patients, whereas 3 patients opted for a "wait-and-test-and-scan" strategy. Of the surgical patients, 3 underwent labyrinthectomy and cochlear implant (CI) surgery in a single stage procedure; 1 patient received extended cochleostomy with CI surgery; 3 underwent partial or subtotal cochleoectomy, with partial cochlear reconstruction and CI surgery (n = 1) or implantation of electrode dummies for possible later CI following repeated MRI follow-up (n = 2); and in 2 patients, the tumors of the internal auditory canal and cerebellopontile angle exhibiting transmodiolar or transmacular growth were removed by combined translabyrinthine-transotic resection...

REVIEW
Hugues Duffau
Neurology, especially aphasiology, was mainly built on behavioral-structural correlations ("lesion method"). In this setting, Broca's area has been considered as the "speech area"; moreover, this observation led to localizationism. However, advances in brain mapping techniques, as functional neuroimaging and direct electrical stimulation in patients undergoing awake surgery for gliomas, has resulted in a paradigmatic shift regarding models of neural architecture. In fact, the brain is organized in distributed complex networks underpinning sensorimotor, visuospatial, language, cognitive and emotional functions...

OBJECTIVES: Debates prevail regarding the definition of surgical talent, and how individuals with the potential to become talented surgeons can be identified and developed. However, over the past 30 years, talent has been studied extensively in other domains. The objectives of this study is to explore notions of talent in surgery and sport in order to investigate if the field of surgical education can benefit from expanding its view on talented performances. Therefore, this study aims to use the sport literature as a lens when exploring how surgeons conceptualize and define talent...

With the increasing number of total knee arthroplasty (TKA) procedures being performed annually, the burden of revision surgery is also expected to increase. Addressing bone loss during revision TKA is a considerable challenge that requires proper preoperative evaluation and surgical planning. In addition to an assessment of femoral and tibial bone loss, a systematic approach to the management of bone loss associated with TKA includes careful implant selection, adherence to the general principles of revision TKA, and an understanding of the available reconstruction options...

BACKGROUND: Surgical site marking is one important cornerstone for the principles of safe surgery suggested by the WHO. Generally it is recommended that the attending surgeon performs the surgical site marking. Particularly in the case of same day surgery, this recommendation is almost not feasible. Therefore we systematically monitored, whether surgical site marking can be performed by trained nursing staff. The aim of the study was to find out whether surgical site marking can be carried out reliably and correctly by nurses...

John W Kieffer
The principle of subsidiarity is a bastion of Catholic social teaching. It is also a principle in the philosophy of the American Founding Fathers. In the USA, subsidiarity is ignored without a sense of the proper harmony between authority and responsibility. Human dignity and wise stewardship are compromised. Conscience protection becomes a concerning issue as highlighted by the conflicts arising after passing of the Patient Protection and Affordable Care Act. A reconnection of the patient to be steward of his health care is critical in addressing these issues...

Peripheral paralysis of the facial nerve is the most frequent of all cranial nerve disorders. Despite advances in facial surgery, the functional and aesthetic reconstruction of a paralyzed face remains a challenge. Graduated minimally invasive facial reanimation is based on a modular principle. According to the patients' needs, precondition, and expectations, the following modules can be performed: temporalis muscle transposition and facelift, nasal valve suspension, endoscopic brow lift, and eyelid reconstruction...

Friedrich Wilhelm Mohr from the very beginning of his career as a cardiac surgeon was involved in the refinements of coronary artery bypass grafting (CABG). At the Leipzig Heart Center, his spirit of early adapting to new technologies inspired the entire team and led to a matchless scientific atmosphere to find solutions to improve almost all fields of cardiac surgery, including CABG. In combination with a tremendous number of patients with indications for isolated coronary artery bypass Prof. Mohr as the surgical principle investigator and the Leipzig Heart Center were able to include patients in the Synergy between PCI [percutaneous coronary intervention] with Taxus and Cardiac Surgery (SYNTAX) trial, the first randomized trials comparing CABG and PCIs using the drug-eluting stents...

Ebbe Thinggaard
When laparoscopy was first introduced, skills were primarily taught using the apprenticeship model. A limitation of this method when compared to open surgery, was that it requires more time to practise and more frequent learning opportunities in clinical practice. The unique set of skills required in laparoscopy highlighted the need for new training methods that reduce the need for supervision and do not put the patient at risk. Simulation training was developed to meet this need. The overall purpose of this thesis was to explore simulation-based laparoscopic training at home...

#18
M Thomas, M Jordan
Severe symptomatic hallux valgus deformities are usually not treatable with conservative methods in the long-term. Surgical treatment currently aims for mechanical restitution of the first ray with preserved mobility of the first metatarsophalangeal (MTP 1) joint and with low risk of recurrence after surgery. Keeping these aims in mind the surgical methods consist of osteotomy at the proximal part of the first metatarsal bone with a high potential for correction of the deformity. Surgical interventions at the midshaft level of the first metatarsal are only useful if the anatomical shape of the metatarsal shows a wide shaft, which allows a large shift in the osteotomy...

OBJECTIVE: Spontaneous spinal epidural hematoma (SSEH) manifests from blood accumulating in the epidural space, compressing the spinal cord and leading to acute neurological deficits. Standard therapy is decompressive laminectomy, although spontaneous recoveries have been reported. Sub-optimal therapeutic principles contribute to SSEH's 5.7% mortality-which patient will benefit from surgery remains unclear. This study aims to investigate parameters that affect SSEH's progression, outlining a best-practice therapeutic approach...

Bone defects arising from a variety of reasons cannot be treated effectively without bone tissue reconstruction. Autografts and allografts have been used in clinical application for some time, but they have disadvantages. With the inherent drawback in the precision and reproducibility of conventional scaffold fabrication techniques, the results of bone surgery may not be ideal. This is despite the introduction of bone tissue engineering which provides a powerful approach for bone repair. Rapid prototyping technologies have emerged as an alternative and have been widely used in bone tissue engineering, enhancing bone tissue regeneration in terms of mechanical strength, pore geometry, and bioactive factors, and overcoming some of the disadvantages of conventional technologies...
