Abstract
Hemifacial spasm (HFS) is a common cranial nerve disease. In HFS research, we conducted a bibliometric analysis to examine the development and research trends. A retrieval of HFS studies published between 2011 and 2022 was performed from the Web of Science Core Collection in September 2022. Two scientometric tools were used to perform bibliometric and visualization-based analyses: VOSviewer and CiteSpace. Bibliometric analysis of 1461 studies published between 2011 and 2022 was carried out using data from 444 journals, 6021 authors, 1732 institutions, and 76 countries/regions. China, the USA, Japan, and South Korea were four key contributors to this study. Shanghai Jiaotong University was the major institution with the larger number of publications. Li Shiting was the most prolific author. Jannetta PJ was the most co-cited author. World Neurosurgery was the top prolific journal. Journal of Neurosurgery was the top co-cited journal. The top five keywords were hemifacial spasm, microvascular decompression, trigeminal neuralgia, surgery, and neurovascular compression. This study examines the research trends in global scientific research on HFS over the last decade. Researchers interested in learning more about current trends and novel research frontiers in this area can benefit from the study.

Kyriakopoulos AM, Nigh G, McCullough PA, Olivier MD, Seneff S. Bell's palsy or an aggressive infiltrating basaloid carcinoma post-mRNA vaccination for COVID-19? A case report and review of the literature. EXCLI JOURNAL 2023; 22:992-1011. [PMID: 37927346 PMCID: PMC10620857 DOI: 10.17179/excli2023-6145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 09/15/2023] [Indexed: 11/07/2023]
Abstract
We report on an aggressive, infiltrating, metastatic, and ultimately lethal basaloid type of carcinoma arising shortly after an mRNA vaccination for COVID-19. The wife of the patient, since deceased, gave the consent for publishing the case. The malignancy was of cutaneous origin and the case showed symptoms consistent with Bell's palsy and trigeminal neuralgia beginning four days post-vaccination (right side head temporal pain). The temporal pain was suggestive for inflammation and impairment of T cell immune activation. Magnetic Resonance Imaging (MRI) showed a vascular loop on the left lateral aspect of the 5th cranial root exit of cerebellopontine angle constituting presumably a normal variant and was considered as an unrelated factor to the right-sided palsy and pain symptoms that corresponded to cranial nerves V (trigeminal nerve) and VII (facial nerve). In this study we describe all aspects of this case and discuss possible causal links between the rapid emergence of this metastatic cancer and mRNA vaccination. We place this within the context of multiple immune impairments potentially related to the mRNA injections that would be expected to potentiate more aggressive presentation and progression of cancer. The type of malignancy we describe suggests a population risk for occurrence of a large variety of relatively common basaloid phenotype cancer cells, which may have the potential for metastatic disease. This can be avoidable with early diagnosis and adequate treatment. Since facial paralysis/pain is one of the more common adverse neurological events following mRNA injection, careful inspection of cutaneous/soft tissue should be conducted to rule out malignancy. An extensive literature review is carried out, in order to elucidate the toxicity of mRNA vaccination that may have led to the death of this patient. Preventive and precise routine clinical investigations can potentially avoid future mortalities. See also Figure 1(Fig. 1).

Abstract
Both Gradenigo's syndrome and Vernet syndrome are rare pathologies of the intracranial space; both involve compression of a particular anatomic location in the skull, thus affecting structures nearby or within that space. A patient presenting with one or both of these syndromes should raise concern for malignancy, head trauma, or an intracranial infection. We present a case of a 39-year-old female with three weeks of left-sided ear, face, and neck pain along with difficulty swallowing and reduced vision in the left eye. Magnetic resonance imaging of the brain revealed fullness in the left nasopharyngeal region, raising concern for malignancy or infection. Biopsy of the mass ultimately revealed Epstein-Barr virus positive nasopharyngeal carcinoma, nonkeratinizing undifferentiated type, along with culture data revealing methicillin-resistant Staphylococcus aureus positive left otomastoiditis. She received chemoradiation therapy along with six weeks of antibiotic therapy. A patient presenting with symptoms reflective of a sinus infection unrelieved by antibiotics with concomitant cranial nerve deficits should raise clinical concern for an intracranial pathology rather than a simple case of sinusitis.

Abstract
INTRODUCTION The basilar artery is one of the two cases in our body where an arterial vessel is formed by the union of two others - the vertebral arteries. It provides vascular supply to essential structures for the main vital functions; the posterior cerebral arteries originate from it as terminal branches, and form part of the anastomotic circle of Willis. IMAGING FINDINGS Congenital and acquired anomalies of the basilar trunk are described. We provide a schematic and detailed representation of normal anatomical variants - mainly represented by the fenestrated basilar artery or the persistence of carotid-basilar anastomosis; course anomalies are also illustrated, with reference to neuro-vascular conflicts and dolichoectasia. Among congenital anomalies, this pictorial review also shows the variants of the basilar origin, such as in the case of basilar trunk arising from only one of the two vertebral arteries, and the calibre changes - which are represented by aneurysm and hypoplasia. The latter appears to be a risk factor for posterior circulation stroke, when associated with a bilateral posterior foetal variant.Among the acquired forms, this pictorial essay describes some clinical cases of dissections, non-congenital aneurysms, thrombosis and tumour with vascular encasing or compression of basilar artery. CONCLUSION CT angiography and MRI allow us to study the posterior intracranial circulation in detail, providing useful pre-treatment information. Therefore, knowledge of congenital or acquired anomalies of the basilar artery is essential for radiologists, neuroradiologists and neurosurgeons.

Intraoperative Findings of Inferior Petrosal Vein During Microvascular Decompression for Hemifacial Spasm: A Single-Surgeon Experience. Front Surg 2022; 9:921589. [PMID: 35756473 PMCID: PMC9226572 DOI: 10.3389/fsurg.2022.921589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Accepted: 05/24/2022] [Indexed: 11/13/2022] Open
Abstract
Objective This study aims to evaluate the impact of the inferior petrosal veins (IPVs) on operational exploration and to analyze related anatomic features. Methods A total of 317 patients were retrospectively studied. Surgical outcomes and postoperative complications were analyzed, and patients were divided into two groups according to whether the IPV was sacrificed or preserved. The diameter of the IPV was also recorded during operation. Furthermore, the position where the IPV drained into the jugular bulb was recorded in each patient, and the influence of different injection points on the operation was analyzed. Results IPVs were conclusively identified in 242/317 (76.3%) of patients, with 110/242 (45.5%) of patients categorized as “IPV sacrifice” versus 132/242 (54.5%) categorized as “IPV preservation.” IPV diameter was observed to be <0.5 mm in 58 cases (23.9%), 0.5 mm–1.0 mm (≥0.5 mm and ≤1.0 mm) in 145 cases (59.9%), and >1 mm in 39 cases (16.2%). The position of IPV drainage into the jugular bulb was at the level of the accessory nerve in 163 cases (67.3%), the level of the vagus nerve in 42 cases (17.4%), and the level of the glossopharyngeal nerve or above in 37 cases (15.3%). The diameters of IPV in the sacrifice group were mainly less than 1 mm (94.5% vs. 75%, P < 0.01), and the cases with draining points near the glossopharyngeal nerve were more than that in the preservation group (27.3% vs. 5.3%, P < 0.01). Conclusion IPV is an obstructive structure in MVD for HFS, with considerable variations in diameters and draining points. IPV near the glossopharyngeal nerve significantly impacts surgical exposure and is often sacrificed for a better view of the operation field. Meanwhile, it is feasible to maintain IPVs with a diameter >1 mm.

Abstract
A retrospective review of 29 patients with neurovascular compression syndrome (NVCS) involving the anterior visual pathway was conducted. Various patterns of NVCS and visual defects were identified, most commonly involving the optic nerve and internal carotid artery. Most patients were stable, except one with progressive visual field defects. Although mostly asymptomatic, NVCS can rarely cause compressive optic neuropathy. NVCS should be kept in the differential diagnosis of normal tension glaucoma, especially with progressive visual loss despite treatment. Patients with progressive visual loss may require decompression surgery. Non-contrast computed tomography scan may miss NVCS, and magnetic resonance imaging is diagnostic.

Abstract
BACKGROUND Microvascular decompression (MVD) success rates exceed 90% in hemifacial spasm (HFS). However, postoperative recovery patterns and durations are variable. OBJECTIVE We aim to study factors that might influence the postoperative patterns and duration needed until final recovery. METHOD Only patients following de-novo MVD with a minimum follow-up of 6 months were included. Overall trend of recovery was modeled. Patients were grouped according to recognizable clinical recovery patterns. Uni- and multivariable analyses were used to identify the factors affecting allocation to the identified patterns and time needed to final recovery. RESULTS A total of 323 (92.6%) patients had > 90% symptom improvement, and 269 (77.1%) patients had complete resolution at the last follow-up. The overall trend of recovery showed steep remission within the first 6 months, followed by relapse peaking around 8 months with a second remission ~ 16 months. Five main recovery patterns were identified. Pattern analysis showed that evident proximal indentation of the facial nerve at root exit zone (REZ), males and facial palsy are associated with earlier recovery at multivariable and univariable levels. anterior inferior cerebellar artery (AICA), AICA/vertebral artery compressions and shorter disease durations are related to immediate resolution of the symptoms only on the univariable level. Time analysis showed that proximal indentation (vs. distal indentation), males and facial palsy witnessed significantly earlier recoveries. CONCLUSION Our main finding is that in contrast to peripheral indentation, proximal indentation of the facial nerve at REZ is associated with earlier recovery. Postoperative facial palsy and AICA compressions are associated with earlier recoveries. We recommend a minimum of 1 year before evaluating the final outcome of MVD for HFS.

Abstract
Background: Glossopharyngeal neuralgia is a rare neurovascular compression syndrome that can lead to paroxysmal craniofacial pain and sometimes cardiovascular symptoms.[1,2] The characteristic pathology involves a vessel (commonly a branch/loop of PICA) compressing the nerve at the root entry/exit zone at the brainstem.[1] Microvascular decompression is a commonly used treatment approach for patients that have failed conservative measures.[2] Case Description: A 72-year-old male presented to the ED following four episodes of syncope. The patient had a multi-year history of right-sided burning/stabbing pain involving the submandibular area and posterior throat. His syncope was related to symptomatic bradycardia that would occur during episodes of pain. His pain was exacerbated by speaking and swallowing and could be triggered by placing his finger in the right external auditory meatus. Interestingly, this maneuver would also trigger his bradycardia. The patient had failed previous pharmacotherapy, and a pacemaker had been placed to protect him from periods of hypotension. MRI/MRA of the brain and cervical spine were unremarkable. Due to his profoundly symptomatic status, the patient was offered a right retrosigmoid craniotomy for microvascular decompression of the right glossopharyngeal nerve. The patient had complete resolution of his pain and bradycardia immediately post-operatively. He was discharged on the second postoperative day and his pacemaker was ultimately removed. The patient continues to be pain free and off medication. Conclusion: Here we present a video case report of microvascular decompression with favorable outcome for an interesting presentation of glossopharyngeal neuralgia. The patient gave informed consent for surgery and video recording.

Abstract
The posterior inferior cerebellar artery (PICA), with its unique anatomical complexity, is of great clinical importance and involved in many diseases including aneurysm, ischemic stroke, neurovascular compression syndrome (NVCS), arteriovenous malformation (AVM), and brain tumor. However, a comprehensive systematic review of the importance of the PICA is currently lacking. In this study, we perform a literature review of PICA by searching all the associated papers in the PUBMED database hoping to provide a better understanding of the artery. The PICA has tortuous and variable course and territory, divided into 5 segments. Various aneurysms involving PICA were not uncommon, of which the treatment is challenging. The PICA infarct typically manifests lateral medullary syndrome (LMS) and is more likely to cause mass effects. The PICA frequently compresses the medulla and the cranial nerves resulting in various neurovascular compression syndromes (NVCS). Arteriovenous malformation (AVM) fed by PICA are associated with aneurysm and dissection which have high risk of rupture and worse outcome. PICA injured by head trauma can cause fatal SAH. VA terminating in PICA probably cause Bow hunter's syndrome (BHS). The PICA supplies many brain tumors and can be used in intracerebellar chemotherapy. The PICA can be exposed and injured during surgeries especially in telovelar approach, and it also plays an important role in bypass surgeries, hinting the surgical importance of PICA. In conclusion, PICA is very important in clinical practice.

Abstract
Background: Tortuous/abnormal vertebral arteries (VAs) sometimes cause neurovascular compression syndromes (NVCs), such as trigeminal neuralgia, hemifacial spasm, and, rarely, myelopathy/radiculopathy. Abnormalities/tortuosity of the VA at the level of the atlas and axis are of particular note; these may be characterized by a persistent first intersegmental artery (PFIA) and C2 segmental type of VA. Herein, we report a 72-year-old male who presented with cervical myelopathy/radiculopathy due to bilateral tortuosity of the PFIA resulting in spinal cord compression at the craniocervical junction. Case Description: A 72-year-old male presented with cervical pain when turning his neck and progressive gait disturbance. The neurological examination demonstrated a moderate myeloradicular syndrome (Nurick Grade III). The magnetic resonance revealed compression of the medulla and spinal cord due to tortuosity of both dorsal VA at the C1 vertebral level. The three-dimensional computed tomography angiogram confirmed bilateral PFIA running medially. In addition, the left side of VA forms fenestration. Surgery through a C1 laminectomy and midline small suboccipital craniectomy, both VAs were transposed and tethered to the ipsilateral dura utilizing Aron Alpha and vinyl prostheses. In addition, a large vinyl prosthesis was inserted between both VAs to protect them from contacting the spinal cord. Following this decompressive procedure, the patient’s symptoms fully resolved, and he remains asymptomatic 10 years later exhibiting no recurrent vascular pathology. Conclusion: Microvascular decompression of anomalous VAs contributing to cord compression at the C1 level was safe and effective in a 72-year-old male.
