Background: During hearing aid (HA) fitting, individuals may experience better speech discrimination at normal speech levels and worse discrimination at loud speech levels than without an HA. Therefore, we investigated factors that worsen speech discrimination when the speech sound level increases.
Methods: Speech discrimination was measured in patients aged >20 years who had average hearing thresholds <90 dB on pure-tone audiometry.
Effect of statins on hearing outcome in patients with idiopathic sudden sensorineural hearing loss.
Laryngoscope Investig Otolaryngol
December 2023
Objective: Statins have been reported to improve vascular endothelial function and microcirculation, reduce oxidative stress, and exert anti-inflammatory and protective effects against inner ear damage. Therefore, this study aimed to investigate the effect of statins on hearing prognosis in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).
Methods: We reviewed the medical records of 149 patients diagnosed with ISSNHL.
Objective: Some studies have directly compared the National Acoustic Laboratories' prescription for non-linear hearing aids (HAs) version 2 (NAL-NL2) and Desired Sensation Level for non-linear HAs version 5 (DSLv5), although none were performed in Japan. As the Japanese language is a tonal language that has different linguistic characteristics than those of the studied languages, we compared the outcomes of the NAL-NL2 and DSLv5 in hearing-impaired Japanese participants.
Methods: A crossover-controlled trial was conducted on 18 first-time HA users with bilateral moderate sensorineural hearing loss.
Background: Few investigations have been conducted on the clinical characteristics of the differential diagnosis of acoustic neuroma with acute sensorineural hearing loss and idiopathic sudden sensorineural hearing loss. The aim of the study was to investigate the clinical characteristics of the differential diagnoses between acoustic neuroma and idiopathic sudden sensorineural hearing loss.
Methods: The medical records of patients with acute sensorineural hearing loss (142 ears), including acoustic neuroma (19 ears) and idiopathic sudden sensorineural hearing loss (123 ears), who underwent audiometric and hematologic examinations and received systemic corticosteroid treatment, were retrospectively reviewed.
Objective: Hearing improvement following stapes surgery is generally good; however, we sometimes encounter patients where hearing loss gradually progresses over the long term. In this study, we investigated the causes of hearing loss in these cases.
Methods: A total of 30 ears from 23 patients, who underwent stapes surgery at Kitasato University Hospital from 2001 to 2021 and were followed up for ≥5 years, were included in the study.
Retrofacial Approach for Cochlear Implantation in Chronic Otitis Media: A Case Report.
J Int Adv Otol
September 2022
Cochlear implantation is anatomically more difficult in postoperative ears than in normal ears due to chronic otitis media. In cochlear implantation after canal wall down mastoidectomy, the electrodes must be protected. We report a case of cochlear implantation with partial mastoid obliteration using a retrofacial approach in an 81-year-old woman.
View Article and Find Full Text PDFBackground: Patients undergoing hemodialysis (HD) tend to experience hearing loss, including idiopathic sudden sensorineural hearing loss (ISSHL). However, little is known about the relationship between HD and ISSHL.
Objective: To investigate the effects of HD on the hearing level and the treatment prognosis of ISSHL.
Background: In idiopathic sudden sensorineural hearing loss (ISSNHL), the relationship between the administration duration of vitamin B12 (vit B12) with adenosine triphosphate (ATP) and their therapeutic effect is not fully understood.
Objective: To investigate the therapeutic effect of long-term 16 (≥weeks) administration of vit B12 with ATP on the prognosis of ISSNHL patients and compare it with those of short-term (<8 weeks) and middle-term (≥8 weeks, <16 weeks) administration.
Methods: We retrospectively reviewed the medical records of 117 patients with ISSNHL treated between 2015 and 2018.
Objective: We used real-ear insertion gain (REIG), with the international speech test signal (ISTS), to evaluate the amplifying characteristics of hearing aids, set for patients who have been wearing such aids for a long time in a stable manner. We further compared this to the target values of the DSLv5 and NAL-NL2 methods.
Methods: The subjects were adults with moderate sensorineural hearing loss.
Objective: This study aimed to compare the difference in maximum speech discrimination score (SDSmax) of the worse-hearing ear in asymmetric hearing loss (ASHL) patients with that in symmetric hearing loss (SHL) patients.
Design: We retrospectively reviewed medical records of patients with suspected hearing loss (HL) who underwent audiometric examinations. Patients were divided into two groups according to the difference in air conduction (AC) threshold between the right and left ears: the SHL group and the ASHL group.
Objectives: Effects of decreasing auditory activity on speech discrimination ability are not fully understood. To investigate influence of decrease in auditory activity due to conductive and sensorineural components of hearing loss (HL) on speech discrimination ability.
Materials And Methods: We retrospectively reviewed medical records of patients with suspected HL at Kitasato University Hospital in 2017 and 2018.
