Background: Meningiomas are known to recur frequently, and their longterm management remains controversial. Previous studies indicate that progesterone its receptors can play a role in the recurrence of meningiomas, but correlation between presence these patients’ outcome is unclear. Aim: To conduct retrospective analysis investigate prognostic relevance receptor (PR) expression meningiomas. Methods: Five hundred eighty eight meningiomas operated on over period 10 years were examined...

Abstract Introduction: Computer‐guided navigation has proven a valuable tool in several surgical disciplines. During oral implant placement, its application is intended to accomplish optimal localization and reduce the risk of damage adjacent structures. The aim this study was compare precision limits conventional vs. navigated insertion practice. Materials methods: In cast models maxilla, implants were inserted replace left central incisor ( n =40) right canine =40); each those either...
Abstract Background NF2-related schwannomatosis (NF2) is associated with various tumors of the central and peripheral nervous system. There a wide range disabilities these patients may suffer from there no validated clinical classification for disease severity. We propose consisting three severity grades to assist in patient management. Methods Patient records 168 were screened most common diagnoses severe impact on everyday tasks, social interactions life expectancy. Eight main categories...
✓ Superior oblique myokymia (SOM) is a rare eye movement disorder presenting as uniocular rotatory microtremor due to intermittent contractions of the superior muscle. Medical treatment usually fails provide long-term benefit for patient and has considerable side effects. Surgical alternatives including tenotomy or partial tenectomy tendon often result in incomplete resolution visual symptoms. The authors report who experienced immediate cessation disabling SOM following microvascular...
Skull base anatomy is complex and subject to individual variation. Understanding the complexity of surgical faster easier with virtual models created from primary imaging data patient. This study was designed investigate usefulness reality in image guidance for skull procedures.Primary volumetric 110 patients acquired using magnetic resonance, computed tomography (CT), CT angiography. Pathologies included lesions anterior, middle, posterior base. The were transferred an infrared-based...
In the early stages of global COVID-19 pandemic hospital admissions for acute ischemic stroke (AIS) decreased substantially. As health systems have become more experienced in dealing with pandemic, and as proportion population vaccinated rises, it is interest to determine whether prevalence AIS hospitalization outcomes from returned normal.In this observational, retrospective cohort study, we compared during first four waves corresponding pre-pandemic periods 2019 using administrative data...
BACKGROUND Quality of life (QOL) has come into focus after treatment for cerebellopontine angle (CPA) lesions. OBJECTIVE This study compared subjective (tinnitus, vertigo) and objective (hearing loss, facial palsy) results CPA surgery with patient-perceived impairment QOL. METHODS A retrospective analysis a consecutive series 48 patients operated on either vestibular schwannoma or meningioma in the was performed. Patient's QOL by tinnitus, vertigo, hearing nerve palsy assessed visual analog...
Microvascular compression of the vestibulocochlear nerve is known to cause disabling tinnitus and vertigo. A review literature shows that usually located in cerebellopontine angle, it caused by an artery. The authors add case a 46-year-old man with venous inside internal auditory canal (IAC). patient presented 2-year history recurrent attacks vertigo intermittent high-frequency on right side. Magnetic resonance images showed small, contrast-enhancing lesion fundus IAC, which was suspicious...
Superior oblique myokymia (SOM) is an ocular motility disorder characterized by oscillopsia, vertical or torsional diplopia, sometimes combined with pressure sensation. Although the pathophysiological basis unclear, isolated case reports have documented its association intracranial pathological processes. We present a of SOM associated vascular compression fourth nerve at root exit zone. Following microneurosurgical decompression, completely resolved and paralysis occurred. This was less disturbing.
OBJECTIVE Being situated close to the transverse and sigmoid sinus, asterion has traditionally been viewed as a landmark for surgical approaches posterior fossa. Cadaveric studies, however, have shown its variability in relation underlying anatomic structures. We used an image-guidance technology determine precise relationship between transverse-sigmoid sinus transition (TST) complex patients scheduled fossa surgery. The applicability of three-dimensional (3-D) volumetric image-rendering...
