“…The approaches were cited, but no quantitative data was given in most of the studies. Among the preferred ones were the far lateral (FL) [24,37,68,71,78], modified far lateral (modified FL) [56,75], Eextended far lateral (EFL) [37], extreme lateral (EL) [3,6,37,42,60,66,73,78], lateral (Lat) [14,46], suboccipital (SO) [9, 11, 13, 19, 21-23, 29, 35, 78, 79], transcondylar (TC) [2,7,36,62,64], transoral (TO) [4,20,63], or transpetrosal [54] with small technical variations also described (Table 3).…”

Foramen magnum meningiomas: a systematic review and meta-analysis

Foramen magnum meningiomas (FMMs) account for 1.8–3.2% of all meningiomas. With this systematic review and meta-analysis, our goal is to detail epidemiology, clinical features, surgical aspects, and outcomes of this rare pathology. Using PRISMA 2015 guidelines, we reviewed case series, mixed series, or retrospective observational cohorts with description of surgical technique, patient and lesion characteristics, and pre- and postoperative clinical status. A meta-analysis was performed to search for correlations between meningioma characteristics and rate of gross total resection (GTR). We considered 33 retrospective studies or case series, including 1053 patients, mostly females (53.8%), with a mean age of 52 years. The mean follow-up was of 51 months (range 0–258 months). 65.6% of meningiomas were anterior, and the mean diameter was of 29 mm, treated with different surgical approaches. Postoperatively, 17.2% suffered complications (both surgery- and non-surgery-related) and 2.5% had a recurrence. The Karnofsky performance score improved in average after surgical treatment (75 vs. 81, p < 0.001). Our meta-analysis shows significant rates of GTR in cohorts with a majority of posterior and laterally located FMM (p = 0.025) and with a mean tumor less than 25 mm (p < 0.05). FMM is a rare and challenging pathology whose treatment should be multidisciplinary, focusing on quality of life. Surgery still remains the gold standard and aim at maximal resection with neurological function preservation. Adjuvant therapies are needed in case of subtotal removal, non-grade I lesions, or recurrence. Specific risk factors for recurrence, other than Simpson grading, need further research.

“…The twelfth cranial nerve, also known as hypoglossal nerve (HN), is a purely somatomotor nerve providing innervation to the extrinsic (genioglossus, hyoglossus, styloglossus) and intrinsic musculature of the tongue. [1][2][3][4][5][6][7][8][9] Since it is commonly encountered in surgical approaches to the craniovertebral junction (CVJ), [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] a detailed knowledge of its anatomy is essential. Lesions of the HN lead to a paralysis of both intrinsic and extrinsic tongue musculature causing dysarthria and swallowing disturbances.…”

The aim of this anatomical study is to describe the anatomy of the hypoglossal nerve (HN) from its origin to the extracranial portion as it appears by performing a combined posterolateral and anterolateral approach to the craniovertebral junction (CVJ). Twelve fresh, non-formalin-fixed adult cadaveric heads (24 sides) were analyzed for the simulation of the combined lateral approach to the CVJ. The HN is divided into three main parts: cisternal, intracanalicular, and extracranial The anatomical relationships between the HN and other nerves, muscles, arteries and veins were carefully recorded, and some measurements were made between the HN and related structures. Thus, various landmarks were determined for the easy identification of the HN. Understanding the detailed anatomy of the HN and its relationships with the surrounding structures is crucial to prevent some complications during CVJ surgery.
