The endoscopic transnasal approach to the lesions of the craniocervical junction: two case reports.

The endoscopic endonasal approach (EEA) to the craniovertebral junction (CVJ) has recently been considered a safer alternative and less invasive approach than the traditional transoral approach because the complications associated with the latter are avoided or minimized. Here, we present two challenging cases of CVJ pathologies. The first case involved os odontoideum associated with anterior displacement of the occipitocervical junction where the EEA was used, followed by C0-C1-C2 fusion using a posterior approach to decompress the CVJ, and was complicated by rhinorrhea and Candida albicans meningitis.

Regression of Giant Olfactory Groove Meningioma and Complete Visual Acuity Recovery after Discontinuation of Cyproterone Acetate.

Purpose: To report on the medical management of meningioma with compression of the optic chiasm associated with the use of cyproterone acetate (CA).

Case Report: A 65-year-old woman who was being treated with CA presented with a recent decrease in visual function, leading to discovery of a giant olfactory groove meningioma with compression of the optic chiasm. CA was discontinued immediately, and her visual function improved dramatically.

A consideration for the utility of the post-operative Oswestry Disability Index for measuring outcomes after sacroiliac joint fusion.

Sacroiliac joint (SIJ) dysfunction and its surgical treatment remain a controversial topic in spine surgery. Determining success after SIJ fusion may be difficult due to preexisting back pain, lumbar fusion (LF), and functional disability. We examine the utility of Oswestry Disability Index (ODI) as a measure of clinical outcomes after minimally invasive SIJ fusion.

[Coexistence of a disc herniation and psoas hematoma revealed by L3 deficiency].

Radiculopathy is a constellation of symptoms secondary to a pathology affecting the nerve root, the most frequent cause of which is a herniated intervertebral disc. We report a case of a 58-year-old man under anticoagulant admitted to the neurosurgery department of Lariboisière hospital (Paris) for an L3 motor deficit that occurred progressively over a period of 24 hours with an L3-L4 disc herniation on the MRI. However, a psoas hematoma was also noted.

The endoscopic endonasal approach to cranio-cervical junction: the complete panel.

We aim to establish a complete summary on the Endoscopic Endonasal Approach (EEA) to Cranio Cervical Junction (CCJ): evolution since first description, criteria to predict the feasibility and limitations, anatomical landmarks, indications and biomechanical evaluation after performing the approach. A comprehensive literature search to identify all available literature published between March 2002 and June 2015, the articles were divided into four categories according to their main purpose: 1- surgical technique, 2- anatomical landmarks and limitations, 3- literature reviews to identify main indications, 4- biomechanical studies. Thereafter, we demonstrate the approach step-by-step, using 1 fresh and 3 silicon injected embalmed cadaveric specimen heads.

Endoscopic Submandibular Retropharyngeal Approach to the Craniocervical Junction and Clivus: an Anatomic Study.

Introduction: Surgery of the craniocervical junction (CCJ) and clivus is technically demanding. For many years, we have used the submandibular retropharyngeal approach for surgery of the upper cervical spine, especially hangman fracture. We hypothesized that submandibular gland resection could offer a significant cranial enlargement of the operative field, up to the clivus.

Hydroxyapatite bone cement application for the reconstruction of retrosigmoid craniectomy in the treatment of cranial nerves disorders.

Background: Retromastoid craniectomy (RSC) is a cardinal surgical approach used to access the posterior fossa. Hydroxyapetite bone cement (HBC) is frequently employed for cranioplasty in efforts to prevent cerebrospinal fluid (CSF) leak, whilst maintaining low complication rates and good cosmetic satisfaction. The authors aim to determine the safety and effectiveness of HBC for reconstruction RSC used for treatment of various cranial nerves disorders.

Drilling of the marginal tubercle to enhance exposure via mini pterional approach: An anatomical study and clinical series of 25 sphenoid wing meningiomas.

Background: The marginal tubercle (MT) of zygomatic bone can be an obstacle in the standard mini pterional (MPT) craniotomy; we aim to evaluate the effect of drilling this MT in enhancing the exposure of MPT craniotomy for resection of sphenoid wing meningiomas (SWMs).

Methods: The authors utilized 60 dry skulls to perform the anatomical part of the study. The MT size was reflected by the distance, wherein point is the most prominent part of MT and point is located on the orbital rim in the same axial plane as point .
