Clinical Advancements in Skull Vibration-Induced Nystagmus (SVIN) over the Last Two Years: A Literature Review.

: Skull vibration-induced nystagmus (SVIN) has become a validated tool for evaluating the vestibular function. The presence of SVIN is a useful indicator of the asymmetry of vestibular function between the two ears. In unilateral vestibular loss, a 100 Hz bone-conducted vibration given to either mastoid immediately causes a primarily horizontal nystagmus.

Novel Otolaryngological and Radiological Manifestations in GAPO Syndrome.

GAPO syndrome is an exceptionally-rare autosomal recessive disorder characterized by growth retardation, alopecia, pseudoanodontia, and optic abnormalities, with fewer than 60 cases reported globally. We present the first documented case in Syria, highlighting novel otolaryngological and radiological findings that expand the clinical spectrum of this syndrome. A 27-year-old male presented with chronic right-sided otalgia, unilateral conductive hearing loss, and persistent sinonasal symptoms.

Exploring the impact of force direction and phase on bone conduction hearing with bone conduction actuator.

A comprehensive understanding of the effects of bone conduction (BC) input force is essential for elucidating BC hearing mechanisms. However, this area remains underexplored due to the inherent difficulties in controlling input forces when BC transducers are anchored to the bone. In this study, the effects of both unilateral and bilateral BC input forces were investigated using a three-dimensional finite element (FE) model of the human head, which allows precise manipulation of input forces.

Harvest of Vestibular End-Organs under Physiologic Conditions during Labyrinthectomy.

The living human inner ear is challenging to study because it is encased within dense otic capsule bone that limits access to biological tissue. Traditional temporal bone histopathology methods rely on lengthy, expensive decalcification protocols that take 9-10 months and reduce the types of tissue analysis possible due to RNA degradation. There is a critical need to develop methods to access fresh human inner ear tissue to better understand otologic diseases, such as Ménière's disease, at the cellular and molecular level.

The aim of this study was to investigate the prevalent health issues associated with malnutrition by utilizing electronic health records (EHR) data. The IBM Watson Health, Explorys platform was used to access the EHR data.

Revisiting the Intratemporal Course of the Facial Nerve.

Introduction The facial nerve displays a lot of variations and anomalies in its course. Having sound knowledge about the surgical anatomy along with its intricacies is essential in mastoid surgeries. In this study, we have documented the angle of deviation of the mastoid segment of the facial nerve during its intratemporal course and the importance of this angle during mastoid surgeries.

The Outcomes of Cochlear Implantation in Patients with Solid Organ Transplant.

Introduction: As far as it is known, long-lasting immunosuppressive therapy might put patients with solid organ transplantation (SOT) at increased risk for severe to profound sensorineural hearing loss, eventually leading to cochlear implantation (C.I). So, the main aim of the present study is to evaluate their auditory perception performance after cochlear implantation.

Navigating the Complication: Acute Mastoiditis Causing Cerebral Venous Thrombosis in an Adult.

Acute mastoiditis is an infection of the air cells in the mastoid and is primarily seen in the pediatric population. This disease usually occurs after patients develop otitis media, which can result in acute mastoiditis as a complication. Most patients usually present with generalized symptoms of an infection; however, in some instances, cerebral venous thrombosis can occur.
