Conductive hearing loss (CHL) is caused by the disruption of the sound conductive chain that, in turn, may be due to diseases of the external and middle ear. High-resolution computed tomography (CT) is the imaging modality of choice to evaluate CHL because of its excellent spatial resolution. Along with clinical and otoscopic findings, CT also helps in the diagnosis and preoperative planning. This pictorial review aims to illustrate the CT features of common conditions causing CHL that may arise from the external and middle ear, as well as highlights some of the key imaging features that are helpful in management...

AIM: Very preterm infants are at risk of neonatal hearing loss. However, it is unknown whether infants with a normal neonatal hearing screening result risk sensorineural hearing loss (SNHL) at a later age. METHODS: This cohort study was conducted at the Erasmus Medical University Center Rotterdam, the Netherlands, on 77 very preterm infants born between October 2005 and September 2008. All infants underwent auditory brainstem response audiometry during neonatal hearing screening and at two years of corrected age...

Percutaneous titanium implants for bone conduction devices (BCDs) have offered, since 1977, a solution for patients with hearing loss not treatable by conventional hearing aids, such as patients with chronic ear infections or microtia and/or ear canal atresia. Percutaneous implants imply a continuous breach in the mechanical defensive barrier of the skin. To compensate for this breach, immunological mechanisms in the subcutaneous tissue surrounding the implant become more active. This article is protected by copyright...

PURPOSE: Congenital cytomegalovirus (cCMV) infection is the most common non-genetic cause of sensorineural hearing loss (SNHL). However, accurate diagnosis of cCMV as the etiology of SNHL is problematic beyond the neonatal period. This study therefore examined whether cCMV infection could be identified retrospectively in children presenting with unexplained SNHL to a multidisciplinary diagnostic outpatient otolaryngology clinic at an academic medical center in Minnesota. METHODS: Over a 4-year period, 57 patients with an age range of 3months to 10years with unexplained SNHL were recruited to participate in this study...

We investigated speech recognition in noise in subjects with mild to profound levels of unilateral hearing loss. Thirty-five adults were evaluated using an adaptive signal-to-noise ratio (SNR50) sentence recognition threshold test in three spatial configurations. The results revealed a significant correlation between pure-tone average audiometric thresholds in the poorer ear and SNR thresholds in the two conditions where speech and noise were spatially separated: dichotic - with speech presented to the poorer ear and reverse dichotic - with speech presented to the better ear...

We report a young female who presented with saddle-nose and bilateral cauliflower ear deformities along with pyoderma gangrenosum-like ulcers, digital gangrene and pulselessness. Subsequently, she was found to have bilateral conductive hearing loss, a corneal opacity, mild aortic regurgitation and radiological evidence of cavitary changes in lungs and aortoarteritis. Our patient had a constellation of symptoms which posed a diagnostic challenge. Finally, a diagnosis of relapsing polychondritis with several unusual features was made...

Importance: Somatization is a condition in which psychological distress is manifested by medically unexplained symptoms, and it is prevalent in all medical specialties, including otolaryngology. Recognition of somatization can be difficult, and there are limited methods available. Objectives: To determine whether patients with somatization respond differently to the review of systems (ROS) portion of the patient interview and whether the ROS can be used to identify patients with somatization...

A modified lateral temporal bone resection (mLTBR) is a unique technique that spares the tympanic membrane (TM) and ossicles in select patients with squamous cell carcinoma (SCCa). The records of 5 patients with SCCa of the temporal bone with negative frozen-section biopsy at the tympanic annulus were reviewed. The mean follow-up time for the patients was 29.2 months. One patient received postoperative radiation due to cervical nodal extracapsular spread. All patients were recurrence free as of the most recent follow-up (range, 8-50 months)...

Hearing loss is hidden disability and second most common congenital pathology. Prevention, early identification and early intervention of hearing loss can prevent further disability in development of speech, language, cognition and other developmental domains. The prevalence of congenital hearing loss has been estimated to be 1.2-5.7 per thousand in neonates. In these contexts, the aim of study was to determine outcomes of neonates hearing screening program in Hospital. It is a clinical cross-sectional study which was conducted in tertiary care centre from 8th July, 2015 to 31th May, 2016...

Genetic mouse models are widely used for understanding human diseases but we know much less about the anatomical structure of the auditory ossicles in the mouse than we do about human ossicles. Furthermore, current studies have mainly focused on disease conditions such as osteomalacia and rickets in patients with hypophosphatemia rickets, although the reason that these patients develop late-onset hearing loss is unknown. In this study, we first analyzed Dmp1 lac Z knock-in auditory ossicles (in which the blue reporter is used to trace DMP1 expression in osteocytes) using X-gal staining and discovered a novel bony membrane surrounding the mouse malleus...

Bone-anchored hearing aids are a widely used method of treating conductive hearing loss, but the benefit of bilateral implantation is limited due to interaural cross-talk. The present study measured the phase and level of pure tones reaching each cochlea from a single, mastoid placed bone transducer on normal hearing participants. In principle, the technique could be used to implement a cross-talk cancellation system in those with bilateral bone conductors. The phase and level of probe tones over two insert earphones was adjusted until they canceled sound from a bone transducer (i...

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm occasionally presenting with features of leukostasis as primary symptoms. Hearing loss is occasionally reported in CML patients. Further whether Imatinib mesylate has any effect on vestibular functions is not known. We conducted a preliminary study to assess hearing pattern in patients with CML on long term TKI therapy. This is a single center, cross sectional study from northern-India. Patients of CML who were on regular Tyrosine kinase inhibitors (TKI) therapy for at least 6 months underwent audiovestibular evaluation ...

Importance: Persistent, viscous middle ear effusion in pediatric otitis media (OM) contributes to increased likelihood of anesthesia and surgery, conductive hearing loss, and subsequent developmental delays. Biomarkers of effusion viscosity and hearing loss have not yet been identified despite the potential that such markers hold for targeted therapy and screening. Objective: To investigate the association of gel-forming mucins and aquaporin 5 (AQP5) gene expression with inflammation, effusion viscosity, and hearing loss in pediatric OM with effusion (OME)...
