Sudden sensorineural hearing loss is a well-recognized clinical symptom in multiple sclerosis (MS). Acute inflammatory demyelination in the cochlear nerve or more central auditory tracts may cause sudden retrocochlear hearing loss. A 28-year-old male patient who was confirmed as having MS presented with suffering from dizziness as well as ongoing right-side hearing loss. We performed audiological tests, such as pure tone audiometry (PTA), otoacoustic emission, auditory brainstem response (ABR), and auditory steady-state response (ASSR)...

OBJECTIVES: To study the compliance of ear, nose, and throat (ENT) physicians to the American Association Otolaryngology-Head - Neck Surgery (AAO-HNS) clinical practice guidelines (CPG) for tinnitus and to identify the disparity of both diagnosis and management options in the absence of a local protocol for the management of adult tinnitus. MATERIALS AND METHODS: A voluntary and anonymous questionnaire was emailed in a Google spread-out sheet format to all practicing ENT physicians across the country (n=370)...

OBJECTIVES: To investigate the effects of topical and systemic administrations of melatonin and dexamethasone on facial nerve regeneration. MATERIALS AND METHODS: In total, 50 male albino Wistar rats underwent facial nerve axotomy and neurorrhaphy. The animals were divided into 5 groups: control, topical melatonin, systemic melatonin, topical dexamethasone, and systemic dexamethasone. Nerve conduction studies were performed preoperatively and at 3, 6, 9, and 12 weeks after drug administrations...

Schwannoma arising from the intermediate nerve is very rare, with only a few cases reported in the literature. Here, we report a rare case of a rapidly growing schwannoma that originated from the intermediate nerve in a 17-year-old woman. We performed tumor resection using the translabyrinthine approach with continuous intraoperative monitoring, in which the facial nerve root was used to evoke muscle action potential. The monitoring revealed the tumor origin and enabled complete surgical resection with the preservation of facial nerve motor function...

Polyarteritis nodosa (PAN) is a systemic vasculitis affecting the small- and medium-sized arteries that may present with hearing impairment. In rare cases, PAN may be associated with progressive labyrinthitis ossificans (LO), an otologic emergency requiring early cochlear implantation (CI) to restore hearing before the complete, irreversible cochlear ossification. We report the first case in the literature of a patient affected by PAN with bilateral sudden sensorineural hearing loss and rapid LO who underwent "emergency" bilateral simultaneous CI...

OBJECTIVES: There is limited literature regarding the objective estimation of auditory attention in healthy individuals who regularly practice dance. This study attempted to evaluate the contralateral suppression of otoacoustic emissions (OAE) in Bharatanatyam dancers and non-dancers. MATERIALS AND METHODS: The study included40 adults (20 dancers and 20 non-dancers) with normal hearing. The differences in the contralateral suppression of distortion product OAE between the groups were compared...

OBJECTIVES: Topical treatment is first choice in the treatment of uncomplicated chronic otitis media. It was intended to assess auditory and histopathological safety of ototopical use of mercurochrome solution in rats with induced tympanic membrane perforation. MATERIALS AND METHODS: The study was conducted on 21 female Wistar-Albino rats which were randomly assigned into 3 groups. In all rats, perforation was performed at right tympanic membrane. Distortion product otoacoustic emissions (DPOAEs) measurements were performed at frequencies of 2000, 3000 and 4000 Hz (with L1/L2: 70 /70 dB at 2f1-f2 frequency; f2/f1 ratio: 1:22) before recovery from anesthesia and signal-to-noise ratio (SNR) were recorded...

OBJECTIVES: The purpose of this trial is to examine the clinical role of iron metabolism on development of Otitis media with effusion. MATERIALS METHODS: This prospective study was conducted in a tertiary referral center. The study group made up of children who had surgery for Otitis media with effusion (OME).Control group was comprised of children who had surgery by a pediatric surgeon for inguinal hernia repair or circumcision operations with normal ear nose throat examination...

OBJECTIVES: To investigate the potential use of Ki-67 and pronuclear cell antigen (PCNA) as indicators of recurrent cholesteatoma. MATERIAL AND METHODS: Patients who had been diagnosed with cholesteatoma and who had undergone canal wall-down mastoidectomy were included in this study. Subjects were divided into two groups: recurrent and non-recurrent (i.e., cases without recurrence for at least 2 years). Ossicular pathologies were recorded. Histopathologic specimens were stained for Ki-67 and PCNA and the percentages of stained cells were calculated...

Verruca vulgaris is commonly seen on the hands, feet, and face, but rarely in the external auditory canal. We report the case of a 57-year-old woman with a huge papillary mass filling the entire external auditory canal, with destruction of the posterior canal wall and excavation into the mastoid bone. We performed en bloc resection of the whole region affected by verruca vulgaris, including the external auditory canal, mastoid skin, and tympanic membrane using canal wall-down mastoidectomy plus meatoplasty...

OBJECTIVES: Electrically evoked compound action potentials (eCAP) recordings are widely used in functional evaluation and fitting of cochlear implants (CI) in clinics. We compared the results from two eCAP recording approaches (StandardART and FineGrain, MED-EL, Austria). The FineGrain method is more advanced than the Auditory Nerve Response Telemetry (StandardART) method in terms of the stimulation and algorithm for the eCAP threshold detection. To understand the benefits of these alterations, we compared the two methods on a larger scale in pediatric CI users alongside evoked auditory brainstem responses (eABR)...

OBJECTIVES: The current study proposes a new and fast technique to record the auditory brainstem responses (ABRs) simultaneously (BiSi-ABR) from two ears. The BiSi-ABR technique can be used to record the ABRs two times faster than with a conventional ABR recording method. The objective of the study was to show the proof of concept and to compare the BiSi-ABR technique with that of a conventional ABRs recording method to test its clinical feasibility. MATERIALS AND METHODS: A repeated-measures design was used, wherein ABRs recorded in the BiSi-ABR were compared with that of conventional ABRs recordings...

OBJECTIVES: Osteogenesis imperfecta (OI) is a systemic connective tissue disease that affects many systems and organs. Features of the disease are bone deformities, blue sclerae, and changes in the teeth, all of which may be accompanied by hearing loss. Bone fragility also affects structures of the ear, with half the patients developing changes in the auditory ossicles, which manifest as hearing loss. The most typical malformation affects the stapes, although the site of malformation within the middle ear varies...

The most recent electrode introductions from Advanced Bionics, the HiFocus™ Mid-Scala and the HiFocus SlimJ arrays, have common design goals intended to provide sufficient access to the necessary frequency range while avoiding intracochlear trauma. The electrode choice, either a pre-curved (mid-scala) array or straight (lateral) array, can be made by the surgeon based on anatomical considerations and/or their preferred surgical approach. Both arrays offer ease of handling, suitability for a round window and cochleostomy based insertion and control of the insertion speed...

As the only medical device used in the treatment for deafness, the cochlear implant has benefited to more than half a million individuals worldwide. However, the device has limited penetration due to its high cost, especially in low- and middle-income countries. China alone has 27.8 million deaf people, but less than 100,000 of them have received a cochlear implant. The Nurotron Venus device was developed to address the need for an affordable yet safe and effective cochlear implant. The present study describes the design, development, and evaluation of the Nurotron intracochlear electrode array...
