BACKGROUND AND PURPOSE High-resolution T2-weighted fast spin-echo MR imaging provides excellent depiction of the cisternal and intracanalicular segments of the vestibulocochlear and facial nerves. Absence or reduction in caliber of the cochlear nerve (deficiency) has been described in association with congenital sensorineural hearing loss (SNHL). Depiction of cochlear nerve integrity may be imp...

The cochlear microphonic is a receptor potential believed to be generated primarily by outer hair cells. Its detection in surface recordings has been considered a distinctive sign of outer hair cell integrity in patients with auditory neuropathy. This report focuses on the results of an analysis performed on cochlear microphonic recorded by transtympanic electrocochleography in response to clic...

Abstract Background Hemophilia B is an X-linked inherited disease, mainly caused by deficiency of factor IX. Severity the disease manifested IX in blood. Case presentation This paper presents our experience cochlear implantation with hemophilia 11-month child profound sensorineural hearing loss. The patient had normal hematological parameters pre-operatively and surgery was uneventful. After 36...

In this study, 75 chub mackerels that were caught in the Canakkale Strait Türkiye between October to December, 2019, examined for presence of parasites. The length and weight all fish measured external body area, oral cavity, nostrils, fins, gills examined. Gill samples under a stereomicroscope suspicious findings preserved 99.99% ethanol. mean 24.84±0.39cm 146.01±7.16 gr, respectively. It was ...

Introduction: Otalgia is one of the complaints which may occur at any age. The etiology of the pain may be in the ear, structures around the ear or other head and neck structures. This is caused by the complex nervous connections in the head and neck areas, the ear, the pharynx and the nose. Since understanding the etiologies of referred otalgia can help in the assessment and treatment of the ...

The olivocochlear (OC) efferent innervation of the mammalian inner ear consists of two subdivisions, medial (MOC) and lateral (LOC), with different peripheral terminations on outer hair cells and cochlear afferent terminals, respectively. The cochlear effects of electrically activating MOC efferents are well known, i.e., response suppression effected by reducing outer hair cells' contribution t...

OBJECTIVES Determine the formation of peripheral and central nervous system (CNS and PNS) transitional zone (PCTZ) along the postnatal mouse cochlear nerve. STUDY DESIGN Prospective, basic science. SETTING Research laboratory. SUBJECTS AND METHODS A novel cryosection model of cochlea-cochlear nerve-brainstem was used in this study. The sections were harvested from a total of 45 mice in 9 ...

OBJECTIVES/HYPOTHESIS To determine the effect of cochlear implantation on tinnitus perception in patients with severe bilateral postlingual sensorineural hearing loss and to demonstrate possible differences between unilateral and bilateral cochlear implantation. STUDY DESIGN Prospective study. METHODS Thirty-eight adult patients were included in this prospective study, as part of a multicen...

The current study evaluates histopathologic changes in the temporal bones of 4 human subjects who underwent revision cochlear implantation. Specimens were removed at autopsy, fixed and prepared for histological study by standard techniques. Specimens were serially sectioned, reconstructed by two-dimensional methods, and the tracks of the initial and revision cochlear-implant electrodes identifi...

OBJECTIVE To explore the anomalies of the temporal bone found on radiologic examination, technical challenges in cochlear implantation, and audiologic benefit derived from cochlear implantation in a series of children with CHARGE association. DESIGN Case series report. SETTING Tertiary referral children's hospital pediatric cochlear implant program. PATIENTS Six children with CHARGE assoc...
