Nodular fasciitis is a benign reactive soft tissue tumor arising from fibroblasts and myofibroblasts. Its incidence is low and misdiagnosis is frequent especially for malignant lesions. This can lead to inappropriate and unnecessary invasive treatment. Nodular fasciitis of the external auditory canal is extremely rare. So far, around fifteen cases have been reported. We present here the case of a 90-year-old patient with nodular fasciitis of the right external auditory canal. The lesion extends anteriorly for 6...

The role of intercalatus nucleus of Staderini (INS), the most caudal of the perihypoglossal nuclei, is much debated. Last research seems to suggest that this nucleus plays a role as a vertical eyes movements integrator. The few clinical reports present in the literature that describe isolated lesions of the INS have described patients presenting in acute with up-beating vertical spontaneous nystagmus. Isolated acute lesion of INS is, in fact, much rare, and, without other neurological signs, is exceptional...

OBJECTIVE: The purpose of the study was to evaluate listening effort in adults who experience varied annoyance towards noise. MATERIALS AND METHODS: Fifty native Kannada-speaking adults aged 41-68 years participated. We evaluated the participant's acceptable noise level while listening to speech. Further, a sentence-final word-identification and recall test at 0 dB SNR (less favorable condition) and 4 dB SNR (relatively favorable condition) was used to assess listening effort...

OBJECTIVE: Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are commonly employed in pre-operative evaluation for cochlear implant surgery. However, with a decrease in the age of implantation, even minor radiation exposure can cause detrimental effects on children over their lifetime. The current study compares different cochlear measurements from CT and MRI scans and evaluates the feasibility of using only an MRI scan for radiological evaluation before cochlear implantation...

OBJECTIVE: To investigate the potential influence of anatomical variation in the anterior inferior cerebellar artery (AICA) on the occurrence and severity of idiopathic sudden sensorineural hearing loss (ISSNHL). METHODS: Ninety ISSNHL patients were enrolled. The anatomical location of the AICA was exhibited using high-resolution magnetic resonance imaging (MRI), and the various AICA types classified by previously reported Chavda and Gorrie methods were analyzed...

Safe and efficient drug delivery to the inner ear has always been the focus of prevention and treatment of sensorineural deafness. The rapid development of nanodrug delivery systems based on hydrogel has provided a new opportunity. Among them, thermo-sensitive hydrogels promote the development of new dosage form for intratympanic injection. This smart biomaterial could transform to semisolid phase when the temperature increased. Thermo-sensitive hydrogel nanodrug delivery system is expected to achieve safe, efficient, and sustained inner ear drug administration...

BACKGROUND: Musical perception requires a host of skills. Instrumental musicians place greater emphasis on motor coordination, whereas vocal musicians rehearse vocal sounds. The study explored the differential advantages of musical background on binaural integration and interaction in musicians (instrumentalists, vocalists) and compared them with age-matched non-musicians. METHODS: Eight six participants aged 20-40 y with normal hearing sensitivity were subjected to binaural tests using a standard group comparison research design...

UNLABELLED: Several technical variations of tympanoplasty have been reported, usually involving the type of graft and/or instruments used. Few studies have focused on the outcome of type-1 tympanoplasty specifically in teaching scenarios. We aimed to describe the results of type-1 tympanoplasty performed by residents, and to investigate potential predictive factors of surgical success. To do so, we did a retrospective analysis of medical records of patients who underwent type-1 tympanoplasty in a tertiary university hospital...

PURPOSE: To construct a symptoms-based prediction tool to assess the likelihood of superior canal dehiscence (SSCD) on high-resolution CT. MATERIALS AND METHODS: Mathematical modeling was employed to predict radiologic evidence of SSCD at a tertiary neurotology referral center. RESULTS: A total of 168 patients were included, of which 118 had imaging-confirmed SSCD. On univariate analysis significant predictors of SSCD presence were: sound/pressure-induced vertigo ( p  = 0...

BACKGROUND AND PURPOSE: Cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (CANVAS) is a neurodegenerative disease of the cerebellum. The disease progression is slow, with up to 25% of people diagnosed needing to use a wheelchair after 15 years from diagnosis. Vestibular symptoms arise from centrally-mediated ocular movement degradation and the reduced vestibular-ocular reflex functioning bilaterally. To date, no report has shown an improvement in VOR gain or gait outcome measures in someone with CANVAS after a course of vestibular physical therapy...

PURPOSE: Misophonia is not investigated much from an audiological perspective. Our study aims to examine the processing of the auditory retro-cochlear pathways in individuals with misophonia. METHODS: A cross-sectional study was conducted among university students who had misophonia. The revised Amsterdam Misophonia Scale was used to determine the severity of misophonia. Participants were divided into mild and moderate-severe misophonia and compared with the healthy control group...

Ménière's disease (MD) patients may suffer episodes of sudden falls, named Tumarkin drop attacks (DAs). This fall occurs abruptly and without warning or loss of consciousness. DAs usually aggravate the clinical picture of MD and are challenging to manage. The present report describes a case treated by cochlear implantation (CI) due to concomitant deafness and offers some clinical considerations for this condition. A male patient aged 48 years with a 10-year history of definite bilateral MD had profound SNHL on the right and severe SNHL on the left side...

BACKGROUND/PURPOSE: With increasing accessibility to the Internet, patients frequently use the Internet for hearing healthcare information. No study has examined the information about hearing loss available in the Mandarin language on online video-sharing platforms. The study's primary purpose is to investigate the content, source, understandability, and actionability of hearing loss information in the Mandarin language's one hundred most popular online videos. METHOD: In this project, publicly accessible online videos were analyzed...

INTRODUCTION: Rotatory chair testing has been used to evaluate horizontal canal function. Frequently used tests include sinusoidal harmonic acceleration test (SHAT) and velocity step test (VST). OBJECTIVES: Assessment of age effect on the SHAT and VST and assessment of test-retest reliability of the parameters of those two tests. METHODS: A prospective study was performed on 100 subjects with no ear or vestibular complaints and normal vestibular evaluation...

BACKGROUND: Studies on animals have demonstrated that maternal iron deficiency anaemia (IDA) could result in decreased cochlear sensory hair cells and reduced amplitudes of distortion-product otoacoustic emissions (DPOAEs) of young guinea pigs. Thus, it is essential to study the functioning of cochlear hair cells using DPOAEs in human newborn babies with maternal IDA. The current study explores maternal IDA's effect on DPOAEs in newborn babies. METHOD: A total of 110 newborn babies with gestational age ≥34 weeks were considered and a 'between-subjects' design was used...

BACKGROUND: Vestibular migraine (VM) is a common cause of dizziness that is underrecognized, underdiagnosed, and challenging to effectively treat. The prevalence, appropriate diagnostic workup, and therapies for VM in low- and lower-middle-income countries (LLMICs) remain understudied. The objective of this scoping review is to evaluate the current state of VM research in LLMICs. METHODS: PubMed, Embase, and Web of Science databases were searched to execute a scoping review of VM...

PURPOSE: Our study aims to compare speech understanding in noise and spectral- temporal resolution skills with regard to the degree of hearing loss, age, hearing aid use experience and gender of hearing aid users. METHODS: Our study included sixty-eight hearing aid users aged between 40-70 years, with bilateral mild and moderate symmetrical sensorineural hearing loss. Random gap detection test, Turkish matrix test and spectral-temporally modulated ripple test were implemented on the participants with bilateral hearing aids...

OBJECTIVE: Contribute to clarifying the existence of subclinical hearing deficits associated with aging. DESIGN: In this work, we study and compare the auditory perceptual and electrophysiological performance of normal-hearing young and adult subjects (tonal audiometry, high-frequency tone threshold, a triplet of digits in noise, and click-evoked auditory brainstem response). STUDY SAMPLE: 45 normal hearing volunteers were evaluated and divided into two groups according to age...

The binaural masking level difference (BMLD) is a psychoacoustic method to determine binaural interaction and central auditory processes. The BMLD is the difference in hearing thresholds in homophasic and antiphasic conditions. The duration, phase and frequency of the stimuli can affect the BMLD. The main aim of the study is to evaluate the BMLD for stimuli of different durations and frequencies which could also be used in future electrophysiological studies. To this end we developed a GUI to present different frequency signals of variable duration and determine the BMLD...

OBJECTIVE: To describe audiological symptoms, audiometric profile, and distortion product otoacoustic emission in symptomatic patients recovering from SARS-CoV-2 infection (positive RT-PCR test) and asymptomatic patients (negative RT-PCR test). METHODS: An analytical cross-sectional study was conducted using data obtained from clinical charts, physical examination, audiometry, and distortion product otoacoustic emission on 40 patients [case patients (CP)] recovering from SARS-CoV-2 infection diagnosed by a positive RT-PCR test and 22 asymptomatic participants with a negative RT-PCR test [non-case (NC)]...
