Arterial aneurysms of the infraclinoid part of the internal carotid artery manifest by Jefferson's I-II syndrome. Similar symptoms are observed in intracranial processes of other origin developing in the immediate vicinity from this portion of the internal carotid artery. The manifestation and type of these symptoms depend on the extension of the pathological process, its localization, and individual anatomic structure of oculomotor nerves.

Anterior cervical fixation is an excellent surgical technique for the removal of anterior compressive elements affecting the spinal cord and nerve roots while addressing cervical instability. However, it is important to recognize the unique challenges posed by the proximity of critical structures, including the trachea, esophagus, carotid sheath, and recurrent laryngeal nerve. Access to the upper cervical spine is often limited to the mandible.

Introduction: Distal arterial occlusions can cause measurable changes in the flow wave profile in proximal segments of the feeding artery. Our objective was to study the diagnostic accuracy of point-of-care ultrasound (POCUS) of the common carotid arteries (CCA) for detection of anterior circulation large vessel occlusion (ac-LVO) in patients with suspected stroke.
Patients And Methods: We conducted a prospective, single-center, observational study of adult patients with suspected stroke admitted in the emergency department.

Objective: Elevated intracranial pressure (ICP), a common complication in traumatic brain injuries (TBI), can lead to optic nerve sheath diameter (ONSD) enlargement and flow spectrum changes from the internal carotid artery (ICA) to middle cerebral artery (MCA). This study will investigate the use of Cervical-Cerebral Arterial Ultrasound (CCAU) for non-invasive ICP assessment and evaluating the related indices' clinical utility in TBI patients with decompressive craniotomy (DC).
Methods: ONSD and flow spectrum changes were measured within 24 h after DC in 106 patients via ultrasonic ONSD measurement and CCAU, simultaneously.

To assess the feasibility and safety of cone-beam computed tomography (CBCT) advanced navigation for optimizing intra-arterial chemotherapy infusion (IACI) in patients with skull base tumors. Retrospective review on 10 consecutive IACI procedures performed in five patients (four women, 1 man) over a 1-year period. The median age of the patients was 71 years (interquartile range: 34-74).

In the present study, we investigated the round window (RW) and neighboring anatomical structures using temporal computed tomography (CT) which are important for cochlear implant (CI) electrodes. In this retrospective study, the temporal CT images of 112 adult patients (45 males and 67 females) were evaluated. We classified mastoid pneumatization, and measured RW diameter, RW-carotid canal (CC) distance, RW-facial nerve mastoid segment (FNMS) distance, RW-pyramidal eminence distance, RW-jugular bulb (JB) distance, and RW-internal acoustic canal (IAC) distance.
