The canalis sinuosus is a neurovascular canal, a branch of nerve of infraorbital canal, through which the anterior superior alveolar nerve passes and then leans medially in course between the nasal cavity and the maxillary sinus, reaching the premaxilla in the canine and incisor region. The purpose of this article is to report a case with the presence of canalis sinuosus, in order to alert and guide professionals and discuss the morphology of this anatomical variation avoiding trans- and postsurgical disorders in dental implants...

The retromolar foramen (RMF) is the bony entrance of the retromolar canal, through which a neurovascular bundle runs. It is essential to locate such anatomic variants in a patient in order to avoid complications in surgery, implant placement, or anesthesia of the area. To our knowledge, there has only been one case report of supernumerary RMF, which reported one bilateral doubled retromolar foramina and one doubled left RMF. We present an extremely rare case in which a right triple RMF was observed on cone beam computed tomography in a cadaver...

BACKGROUND: Intraoperative neurovascular complications with clavicle fracture fixation are often due to far cortex penetration by drills and screws, but could be avoided using a unicortical construct. The objective of this study was to compare the bending and torsional strength of a unicortical locking screw plate construct and a hybrid (with central locked and outer non-locked long oblique screws) unicortical plate construct for clavicle fracture fixation with that of a conventional bicortical locking screw construct of plate fixation...

Neurovascular surgery is a broad and challenging, yet exciting field within neurologic surgery. The neurovascular surgeon must be meticulous; because the brain and spinal cord are unforgiving to ischemic insults. Along with the pressures of this demanding subspecialty comes the potential to help patients recover from potentially devastating pathology to go on and lead normal, healthy lives. Several intraoperative imaging modalities are available to help maximize treatment success while reducing risk. This article reviews each of these modalities, including digital subtraction angiography, fluorescence angiography, Doppler ultrasonography, laser Doppler, laser speckle contrast imaging, neuronavigation, and neuroendoscopy...

Spinal instrumentation often involves placing implants without direct visualization of their trajectory or proximity to adjacent neurovascular structures. Two-dimensional fluoroscopy is commonly used to navigate implant placement, but with the advent of computed tomography, followed by the invention of a mobile scanner with an open gantry, three-dimensional (3D) navigation is now widely used. This article critically appraises the available literature to assess the influence of 3D navigation on radiation exposure, accuracy of instrumentation, operative time, and patient outcomes...

PREMISE: Trigeminal neuralgia is a severe facial pain disorder that has been studied for decades. Classical trigeminal neuralgia (CTN) is either idiopathic or caused by neurovascular compression. The related painful trigeminal neuropathies are often secondary to other causes, such as multiple sclerosis or trauma. PROBLEM: Therapies for trigeminal neuralgia and neuropathy have often been pharmacologic or surgical. Pharmacologic therapies are not effective in some cases and often cause side effects, some substantial...

INTRODUCTION: Complex skull base approaches are frequently used to treat intracranial vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) aneurysms. These complex procedures are associated with higher risk of neurovascular injury. Hence, a less invasive surgical approach is needed to improve treatment's efficacy and safety. MATERIAL AND METHODS: A retrospective analysis was conducted on clinical and radiological data from surgeries where simple lateral suboccipital and "lateral enough" approaches were used to clip VA aneurysms in the Department of Neurosurgery at Helsinki University Central Hospital from 2000 - 2009...

Gender reassignment surgery has gained in popularity with increased media exposure and society's recognition of gender dysphoria. Female-to-male gender reassignment often begins with the "top" or chest surgery. Mastectomy with free nipple grafting is the most frequently described technique in the literature. This technique is reliable yet lacks the ability to provide a true male chest shape. We discuss our technique for female-to-male "top" surgery combining traditional mastectomy techniques with a lower pole pedicle vascularized areola and a pectoral implant...

Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders...

Objective  Cavernous sinus hemangiomas (CSHs) are benign lesions accounting for less than 2% of the cavernous sinus tumors. They provide a formidable surgical challenge because of their vascularity and their being surrounded by critical neurovascular structures. In this study, one of the largest in available literature, we analyze our experience in the management of these unusual tumors and review the available literature. Materials  This is a retrospective analysis of patients who were managed surgically (both microsurgical and Gamma knife radiosurgery [GKRS]) for CSH at our Institution from 2007 to 2015...

Tumours of the presacral space are rare to present. Most of them are benign masses, very rarely malignant. Surgery is the mainstay of treatment as it establishes the diagnosis and prevents the adverse consequences associated with malignant degeneration and secondary bacterial infection. Their surgical excision is often difficult because of their anatomic location. Very few cases have been reported so far concerning a laparoscopic management of presacral tumour. We hereby present a young girl with recurrent presacral teratoma...

Craniopharyniomas arise from the sellar region and are particularly challenging because of their close proximity to critical neurovascular structures, including cranial nerves, brainstem, internal carotid arteries, posterior cerebral arteries, hypothalamus, and the pituitary gland. The tumors are benign on histology but can cause serious symptoms by compression of surrounding vital structures. While radical surgery and gross total resection (GTR) remains the first line treatment, choosing the optimal surgical approach is critical for the minimization of complications and post-operative morbidity...

OBJECTIVE Tumors with cavernous sinus (CS) invasion represent a neurosurgical challenge. Increasing application of the endoscopic endonasal approach (EEA) requires a thorough understanding of the CS anatomy from an endonasal perspective. In this study, the authors aimed to develop a surgical anatomy-based classification of the CS and establish its utility for preoperative surgical planning and intraoperative guidance in adenoma surgery. METHODS Twenty-five colored silicon-injected human head specimens were used for endonasal and transcranial dissections of the CS...

Thoracic outlet syndrome (TOS) is a constellation of signs and symptoms caused by compression of the neurovascular structures in the thoracic outlet. TOS may be classified as either neurogenic TOS (NTOS) or vascular TOS: venous TOS (VTOS) or arterial TOS (ATOS), depending on the specific structure being affected. The basis for the surgical treatment of TOS is resection of the first rib, and it may be combined with scalenectomy or cervical rib resection. Herein, we describe a case of arterial thoracic outlet syndrome which was successfully treated with totally endoscopic video-assisted thoracoscopic surgery (VATS) first rib resection...

Nervus intermedius neuralgia is one of the craniofacial neuralgias, which is extremely rare compared with trigeminal or glossopharyngeal neuralgia. Despite its unique symptom, the aetiology remains unclear. We present a case of a surgically treated 36-year-old woman who suffered from paroxysmal stabbing deep-ear pain for over 10 years. Preoperative magnetic resonance imaging demonstrated a vascular loop compressing the root entry zone of the vestibulocochlear nerve between the seventh and eighth cranial nerves, suggesting nervus intermedius neuralgia as a cause of her pain...
