Abstract Objectives This study aimed to demonstrate resection of a craniovertebral junction (CVJ) meningioma via the posterolateral approach. Design The study is designed with a two-dimensional operative video. Setting This study is conducted at department of neurosurgery in a university hospital. Participants A 50-year-old woman who presented with lower cranial nerve findings due to a left-sided lower clival meningioma (Fig. 1). Main Outcome Measures Microsurgical resection of the meningioma and preservation of the neurovascular structures. Results The patient was placed in park-bench position and a left-sided retrosigmoid suboccipital craniotomy, followed by C1 hemilaminectomy and unroofing the lip of the foramen magnum, was performed. The dural incision extended from the suboccipital region down to the posterior arch of C2 (Fig. 2). The arachnoid overlying the tumor was incised, revealing the course of the cranial nerve (CN) XI on the dorsolateral aspect of the tumor. The left vertebral artery (VA) was encased by the tumor which was originating from the dura below the jugular foramen. The mass was resected in a piecemeal fashion eventually. At the end of the procedure, all relevant cranial nerves and adjacent vascular structures were intact. Postoperative magnetic resonance imaging (MRI) confirmed total resection and the patient was discharged home on postoperative day 3 safely. Conclusions Microsurgical resection of the lesions of the CVJ are challenging as this transition zone between the cranium and upper cervical spine has a complex anatomy. Since adequate exposure of the extradural and intradural segments of the VA can be obtained by the posterolateral approach, this approach can be preferred in cases with tumors anterior to the VA or when the artery is encased by the tumor.The link to the video can be found at: https://youtu.be/d3u5Qrc-zlM.

Cranial Nerve Palsies

<b><i>Introduction:</i></b> A number of neurological complications of COVID-19 have been identified, including cranial nerve paralyses. We present a series of 10 patients with lower cranial nerve involvement after severe COVID-19 infection requiring hospitalization in an intensive care unit. <b><i>Methods:</i></b> We conducted a retrospective, observational study of patients admitted to the post-intensive care unit (p-ICU) of Besançon University Hospital (France) between March 16 and May 22, 2020. We included patients with confirmed COVID-19 and cranial neuropathy at admission to the p-ICU. All these patients were treated by orotracheal intubation, and all but one underwent prone-position ventilation therapy. <b><i>Results:</i></b> Of the 88 patients admitted to the p-ICU, 10 patients (11%) presented at least 1 cranial nerve palsy. Of these 10 patients, 9 had a hypoglossal nerve palsy and 8 of these also had a deficit in another cranial nerve. The most frequent association was between hypoglossal and vagal palsies (5 patients). None of the patients developed neurological signs related to a global neuropathy. We found no correlation between the intensity of the motor limb weakness and the occurrence of lower cranial nerve palsies. All but 2 of the patients recovered within less than a month. <b><i>Conclusion:</i></b> The mechanical compressive hypothesis, linked to the prone-position ventilation therapy, appears to be the major factor. The direct toxicity of SARS-CoV-2 and the context of immune dysfunction induced by the virus may be involved in a multifactorial etiology.

Objective: Sitting position for operation of posterior fossa lesions, occipital and posterior parietal lesions, foramen magnum, upper cervical spinal lesions provides an excellent visualization because of slack of brain due to gravity drainage of CSF and blood. Hence gross total tumour removal relatively easy and less complicative.Methods: From January 2008 to march 2010 total 30 cases underwent neurosurgical procedure in sitting position. Physical characteristics including patients age, sex, size of the tumour and histological diagnosis were collected. The post operative image were studied to see the extent of tumour removal and early detection of complications. Almost all patients required peroperative cerebral venous line or peripheral inserted central venous line, precordial doppler sound, ETCO2, O2 saturation and close monitoring of blood pressure.Results: Venous air embolism were detected in two cases (6.6%). Total tumour removal was possible in 17 (56.6%) cases and subtotal in 11 (36.6%) cases. There were 4 (13.33%) mortality in thirty cases, two cases from CP angle tumour and another case from petroclival meningioma and another from pineal region tumour. There was pneumocephalus in almost all cases and post-operative new facial paresis in 10 (33.3%) cases. Fifth cranial nerve palsy developed in 3 (10%) cases. Temporary lower cranial nerve palsy developed in 2 cases. Post-operative tumour bed haematoma developed in 4 (13.33%) cases. Most of the patient had good outcome (GOS 5).Conclusion: Sitting position can be safely done with good preoperative physiological, peroperative close monitoring of the patient regarding blood pressure, ETCO2 and oxygen saturation. However postoperative complication like tumour bed haematoma, pneumocephalus, cranial nerve palsy have to be bring in mind.Bangladesh Journal of Neuroscience 2012; Vol. 28 (1): 45-51
