The main goal of this research was to discover the influence of high frequency sensorineural hearing loss on familiar speaker recognition during earwitnessing line-ups. The secondary objectives were to estimate the influence of familiarity with voices of the suspects on performance in the auditory speaker recognition test, and to correlate the results with forensically important factors such as a confidence scale from the line-up markings. The recordings from the line-up sessions were low-pass filtered to ensure an equal degree of signal distortion for all subjects and imitate the moderate, severe and profound hearing loss conditions. The results show that the correlation between mimicked hearing impairment and ability to identify a familiar speaker is statistically significant. It was observed that higher degree of signal distortion caused lower accuracy of recognition. Interestingly, it was reported that higher levels of familiarity and exposure to speakers’ voices had a negative effect on speaker identification.

Background: Bacterial meningitis is one of the major factors in the etiology of acquired sensorineural hearing loss in children and adults. Cochlear implantation in these patients is challenging because of inner ear ossification and fibrosis, and this procedure sometimes achieves poorer outcomes in this scenario than with other causes of sensorineural hearing loss. There has been little research into the factors affecting the outcomes of this procedure. Objective: To evaluate the outcomes of cochlear implantation in patients with postmeningitis profound sensorineural hearing loss and to evaluate the factors that affect the results. Materials and Methods: A retrospective review was conducted of thirty patients who were diagnosed with post meningitis profound hearing loss and underwent cochlear implantation at Rajavithi Hospital between 2001 and 2016. Preoperative language status, duration of deafness, preoperative imaging, and degree of electrode insertion were recorded. Categories of auditory performance-II test (CAP-II) was evaluated in all cases, one year postoperative. Results: Thirty postmeningitis deafness patients underwent cochlear implantation. The median age at diagnosis of meningitis and age at implantation were 41 years (range 1 to 75) and 49.50 years (range 3 to 75), respectively. The median duration of deafness was 12 months (range 4 to 300), and the overall mean CAP-II at one year after surgery was 5.47±2.21. The postlinguistic group had a significantly higher CAP-II score than the prelinguistic one (p=0.006). Electrodes were successfully totally inserted in 19 patients (63.3%) and partially inserted in 11 (36.7%). The average CAP-II score in the group with fully-inserted electrodes was significantly higher than in the group with partially-inserted electrodes (p=0.045). There was no correlation between CAP-II score and age at meningitis diagnosis (p=0.069), age at time of surgery (p=0.105), duration of deafness (p=0.506), or preoperative CT (p=0.228) or MRI abnormality (p=0.078). Conclusion: Cochlear implantation in patients with postmeningitis profound hearing loss had high success rates and favorable outcomes. Preoperative language status and degree of electrode insertion were factors that affected auditory performance results.

The cochlear form of otosclerosis is characterized by irreversible metabolic changes that lead to complete hearing loss. Cochlear implantation, which is a high-tech method of rehabilitation for patients with profound hearing loss and complete deafness, becomes an opportunity for hearing restoration. However, CI in patients with cochlear otosclerosis may be accompanied by a number of difficulties due to the remodeling of the cochlea of varying severity. Thus, changes in the bony labyrinth play a crucial role in the management of patients with the cochlear form of otosclerosis and sensorineural hearing loss IV.

Introduction: Surgical treatment of deafness by cochlear implants is used for more than 40 years, and during this period permanently, gradual and significant expansion of indications for this surgery has been observed. Material and methods: In our Department in the years 1994-2018 1480 cochlear implantations were performed, both in adults (647) and in children (883). In this study current indications and the rules for eligibility of patients based on 25 years of experience are presented. Results: Indications for cochlear implantation in adults are: 1) bilateral postlingual deafness, 2) bilateral sensorineural hearing loss - in pure tone audiometry > 70 dB HL (average 500-4000 Hz) and in speech audiometry in hearing aids understanding < 50% of words for the intensity of the stimulus 65 dB, in the absence of the benefits of hearing aids, 3) bilateral profound hearing loss for high frequency with good hearing for low frequency, in the absence of the benefits of hearing aids, 4) some cases of asymmetric hearing loss with intensive tinnitus in the deaf ear. An indication in children is bilateral sensorineural hearing loss > 80dB HL confirmed by hearing tests, after about 6 months of rehabilitation with the use of hearing aids. Discussion: Although cochlear implantation is used for more than 40 years, the indications for this treatment underlies constant modifications. They concern the age of eligible patients, implantation in patients with partially preserved hearing, as well as treatment for patients with difficult anatomical conditions. In many countries, bilateral implantations are commonly performed, and more and more centers recommend this treatment in the case of unilateral deafness or asymmetric hearing loss, especially with the accompanying tinnitus in the deaf ear.

Objective: To determine the prevalence and features of inner ear anomalies in children with congenital profound hearing loss who presented at our cochlear implant center based on imaging studies. Methods: This retrospective study reviewed charts of children with congenital SNHL, who presented to Department of Otolaryngology & Auditory Implant Centre, Capital Hospital Islamabad over a period of 2 years from 1st May 2017 to 30th April 2019. These included 481 cases of both genders aged between 1 to 12 years. After gathering demographic data, audiological data, computed tomography findings of the temporal bone were analyzed. Data was analyzed using SPSS 22. Results: The Inner Ear Malformations were identified in 48(10%) children including 28 (58.33%) males and 20 (41.67%) female. Most 20(41.67%) presented at >3-5 years of age followed by 19(39.58%) at 2-3 years. However, no significant association of gender (p=0.57, p=0.076) and age of presentation (p=0.344, p=0.697) for right and left ears was noted with inner ear malformations. The most common anomaly noted were CLA, CH-III and CH-II in decreasing order of frequency in both ears. Conclusion: The prevalence of IEM’s was found to be 48(10%). Commonest anomalies noted were CLA, CH-III and CH-II. No significant association of gender and age of presentation was noted with type of anomaly in both ears. doi: https://doi.org/10.12669/pjms.36.7.3134 How to cite this:Ahmed J, Saqulain G, Khan MIJ, Kausar M.

Single Sided Deafness

Unilateral Sensorineural Hearing Loss (USNHL) or even Single Sided Deafness (SSD) were mistakenly believed in the past that they could not induce a notable negative effect on the average individual adult. Respectively, a child with USNHL could eventually develop typically and adequately with no particular challenges. Today, it is well established that both children and adults with USNHL and SSD experience difficulties locating sound sources than their normal peers attributable to the concomitant deprivation of data utilized for localization; interaural time differences along with interaural intensity differences, especially for high frequency sounds. Moreover, USNHL and SSD patients suffer from the absence of the binaural benefits that permit people with bilateral Normal Hearing (NH) to perform relatively well in challenging listening environments. These benefits encompass binaural summation that causes improved speech perception, and binaural release from masking that facilitates word recognition in noise. Rising treatment strategies, involving various type of amplification, Assistive Listening Devices (ALSs) and Cochlear Implantation, can greatly widen our overall approach regarding USNHL and / or SSD. Nevertheless, most recent evidence points out that both prompt and adequate intervention is crucial to promote optimal outcomes.

History Of

The A1555G mitochondrial deoxyribonucleic acid (mtDNA) point mutation has classically been associated with sensorineural hearing loss in patients following aminoglycoside exposure. More recently, the mutation has been implicated in sensorineural hearing loss in patients without previous aminoglycoside use. In addition, cochlear implantation has been shown to be effective in the group of patients with prior aminoglycoside exposure but, to date, no case of cochlear implantation in a patient with the A1555G mutation and no prior exposure to aminoglycosides has been explicitly described in the literature.We report the case of an 80-year-old woman with the A1555G mtDNA mutation, a 35-year history of bilateral progressive hearing loss and no history of aminoglycoside exposure who underwent successful implantation of a Nucleus 24 Contour device at our institution. Post-operatively, the patient exhibited marked improvement in tests of auditory performance.We conclude that cochlear implantation can be an effective method to restore some sense of hearing in patients with the A1555G mtDNA mutation and sensorineural hearing loss.

<p>Sudden Hearing loss has been rarely reported as a presenting symptom of malaria fever. It’s even more rare to have a bilateral profound sudden sensorineural hearing loss. A 19 years old female student presented with fever, body weakness, hearing loss with tinnitus. Laboratory investigations done were essentially normal except blood film for malaria parasite which showed a high concentration of the parasite in blood on both occasions. Otoacoustics emission test was passed bilaterally while auditory steady state response showed profound hearing loss bilaterally. Normal hearing was restored within 48 hrs of commencement of anti-malaria drugs and low dose steroids. </p>

Initial Symptoms

Since December 2019, when it was first detected in Wuhan, the SARS-CoV-2 (COVID-19) has spread across the globe. The pandemic has had an unprecedented impact on the global population with >110 million confirmed cases and 2.5 million deaths. The most common initial symptoms of COVID-19 infection are cough, dyspnoea, fever, malaise and anosmia. Severe clinical manifestations include respiratory compromise, pneumonia, organ failure and death. There have been many other less common symptoms as a result of COVID-19 described in the literature, including significant rates of olfactory dysfunction. However, we believe there has been only one other previously documented cases of bilateral hearing loss.Sudden sensorineural hearing loss is a relatively common presentation seen by otolaryngologists. It is defined as rapid hearing loss, ≥30 dB occurring over 3 consecutive days in three contiguous sound frequencies. The exact pathological process is yet to be fully characterised, though it is most commonly unilateral and commonly develops shortly following viral infection. Treatment typically consists of glucocorticoid steroids administered orally, via intratympanic injection or a combination of both routes though there are currently no standardised management of these patients.Bilateral sudden sensorineural hearing loss (SSNHL) is rare, accounting for <2% of all cases. We describe a case of bilateral SSNHL in a 68-year-old patient who presented with profound hearing loss shortly after symptomatic infection with COVID-19, which at the time of publication is the first such case reported in the literature.
