Article Abstract
Craniovertebral junction (CVJ) surgery encompasses a wide spectrum of neurosurgical procedures ranging from transoral approaches for CVJ bone anomalies to surgery for intramedullary tumours. Intraoperative neurophysiological monitoring (IONM) has been increasingly used in recent years because of its ability to prevent neurological complications during surgery. In CVJ surgery the risk of neurological injuries is related first to the positioning of the patient and then to the surgical procedure. Application of IONM during the positioning of the patient permits fast recognition of impending causes of neurological injury. During surgery, continuous IONM permits real-time assessment of the functional integrity of the spinal tracts and provides useful feedback during surgical manoeuvres. The applications of IONM are mainly related to intradural procedures, but wider application of these techniques during surgery for CVJ instability and degenerative disorders has recently been described, leading also to better understanding of the pathophysiology of spinal cord injuries. In this paper we review and discuss the principal IONM techniques used during surgery around the CVJ.

Background: The transoral transpharyngeal odontoidectomy, followed by occipitocervical fixation, have traditionally been a recognized method for ameliorating ventral compression at the craniovertebral junction (CVJ), despite its associated comorbidities. As an alternative, the endoscopic endonasal odontoid resection is a viable approach for various CVJ abnromalities that preserve the oropharynx and leads to fewer procedure-related complications(1-4). We present our case to detail the technical nuances of the procedure and its advantages over other techniques.

Background: The far-lateral approach, frequently employed by skull base surgeons, targets lesions in the ventrolateral region of the craniovertebral junction (CVJ). Although various incisions can be utilized, the linear incision is notably less invasive and more efficient. Despite its advantages, the literature lacks a comprehensive description of the technical steps involved in this approach.

Article Synopsis
- - The endoscopic endonasal corridor (EEO) is an effective surgical route for treating craniovertebral junction (CVJ) issues, particularly beneficial for elderly patients with health complications who may not tolerate more invasive procedures.
- - In a specific case study of an 80-year-old man, EEO was successfully used to address ventral compression caused by degenerative changes, while preserving the C1 anterior arch.
- - The surgery demonstrated positive outcomes without the need for posterior instrumentation, highlighting the technique's effectiveness and the importance of thorough preoperative planning.

Article Synopsis
- The study investigates the effectiveness of a new endoscopic technique (Extended Endoscopic Transodontoid approach, or ETO) for surgeries at the craniovertebral junction, comparing it to the traditional method (transoral-transpharyngeal approach).
- Results showed that ETO significantly improves surgical exposure and increases the distance that can be resected compared to the traditional approach, with a 52% improvement in resection distance.
- Predictive lines used to assess the surgical limits were effective in the traditional method but showed limited utility in the newer ETO technique.

Fibrous dysplasia (FD) is a rare skeletal disorder characterized by the replacement of normal bone with fibrous connective tissue, leading to abnormal bone formation. This case report details the successful treatment of a 61-year-old woman with FD at the craniovertebral junction (CVJ). The patient, who had a history of intracranial meningioma and had already been diagnosed with FD, experienced worsening gait disturbance and muscle weakness following a fall.
