“…The interperiosteodural space, also known as extra-dural neural axis compartment, represents the third JF compartment. It is sited between the outer endosteal and the inner meningeal layers and is composed of an epidural adipose matrix and veins -the inferior petrosal sinus, the jugular bulb and their anastomoses (Figure 4a) [1][2][3][4][5]. In our patient, the lesion originated from leptomeningeal melanocytes and spread between the arachnoid and the inner meningeal dural layer within the interperiosteodural space, displaced the lower cranial nerves and expanded towards the CMC cerebello-medullary and CPC cerebello-pontine cisterns (Figure 4b).…”

“…The jugular foramen (JF) is an irregular bony canal located in the medial-inferior surface of the petrous pyramid between the condylar portion of the occipital bone and the petrous portion of the temporal bone. Its anatomy is complex as it houses the glossopharyngeal nerve (GPN) and its tympanic branch, the inferior petrosal sinus, the meningeal branches of the ascending pharyngeal artery, the jugular bulb, the vagal nerve (VN) and the spinal accessory nerve (SAN) [1][2][3][4][5]. The JF can be the site of several tumours with paragangliomas, schwannomas and meningiomas being the most commonly reported [6][7][8][9][10].…”

“…However, removal of the occipital condyle represents a potential risk for craniocervical junction instability. [5,9,15,46] Anterior approaches alone are not preferred for JFTs as they allow access only to small ventrally located JFTs. The subtemporalinfratemporal approach represents the major variant of the anterior approaches.…”

BACKROUND: The feasibility of a novel skull base approach, the navigated minimal ly invasive presigmoidal suprabulbar infralabyrinthine approach (NaMIPSI-A) without rerouting of the fallopian canal for selected jugular foramen tumors (JFTs), has been demonstrated in a neuroanatomical laboratory study.OBJECTIVE: Here, we present our clinical experience with this approach for selected JFTs, with a particular focus on its e cacy and safety.METHODS: All patients with JFTs who were treated via the NaMIPSI-A were included in this study. The JFTs were classi ed according to a modi ed Fisch classi cation. The neurological and neuroradiological outcome, the extent of tumor resection, and the approach-related morbidity were examined.RESULTS: Five patients (two women, three men; mean age 57y, range 48-65) were available. According to the modi ed Fisch classi cation, two JFTs were graded as C1, one as De1 and two as De2. Gross total resection (GTR) was achieved in three patients and near-total resection (NTR) in two. Postsurgically, no new neurological de cits and no approach-related morbidity and mortality occurred. One case with a postoperative cerebrospinal uid leak was managed successfully with lumbar drainage. During the follow-up period (mean 67,6 months, range 12-119 months) tumor recurrence was noted in the NTR group but not in the GTR group.CONCLUSIONS: The NaMIPSI-A to the jugular foramen without rerouting of the fallopian canal is highly valuable for selected tumors of the jugular foramen. It is less invasive than other skull approaches, and it allows safe and complete tumor removal in appropriate patients.

“…Pars nervosa is located in the anteromedial part and the inferior petrosal sinus and glossopharyngeal nerve (cranial nerve 9) pass through it. Also, pars vascularis is located in the posterolateral part and the vagus nerve (cranial nerve 10), accessory nerve (cranial nerve 11), jugular bulb and posterior meningeal artery pass through it [ 1 , 2 ].…”

Background Differentiating jugular foramen from hypoglossal canal in computed tomography (CT) scan is vital for correct diagnosis of posterior fossa pathologies; however, it has been shown that the ability for differentiating these skull base elements is limited. The purpose of this study was to produce a simple algorithm for differentiating the jugular foramen from the hypoglossal canal in axial CT scan on two levels (top level where bony carotid canal is evident and lower level where bony carotid canal is not evident). Methods Data derived from axial CT scan of 250 patients (500 sides) were used for producing algorithm. At top level petro-occipital fissure utilized for recognizing occipital condyle in which hypoglossal canal is located; and, at lower level the distance between the posterior border of the anatomic element (jugular foramen or hypoglossal canal) and the tangent to the anterior bony part is used for producing algorithm. Results The mean age of patients was 38.1 ± 19 years. The petro-occipital fissure can be used in all patients for differentiating hypoglossal canal. At lower level the distance between the anterior tangent and the posterior border of the element was significantly lower for hypoglossal canal (P value < 0.001). The distance more than 3.5 mm with sensitivity 83.8% and specificity 97.1% differentiate jugular foramen from hypoglossal canal. Conclusion Simple algorithms based on quantitative morphologic features of the jugular foramen and hypoglossal canal can be used with high sensitivity and specificity to distinguish these elements.
