The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3 to 5% of cases after ear tube placement as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year and the commonly used cartilage grafting technique has a success rate between 43% to 100%...

BACKGROUND: Few systematic reviews have been conducted regarding aural rehabilitation for adults with hearing loss, with none specifically targeting the older adult population. With prevalence rates of hearing loss being highest in older adults, examining the effects of aural rehabilitation on this population is warranted. PURPOSE: To evaluate the effects of aural rehabilitation on quality of life in an older adult population presenting with hearing loss. ELIGIBILITY CRITERIA: Studies with adults presenting with hearing loss, ≥50 yr of age, with or without hearing aids, receiving interventions such as auditory training, speech-reading, communication strategies training, speech tracking, counseling, or a combination of approaches, and measuring outcomes related to quality of life, in an individual or group format, with or without significant others and with no limitations as to year of publication...

We prospectively evaluated the surgical, audiologic, and quality-of-life outcomes in 5 patients-2 men and 3 women, aged 22 to 64 years (mean: 41.8)-who were implanted with the Sophono Alpha 2 MPO Processor. The indications for implantation of this bone-conduction device included recurrent ear canal infections with hearing aids (n = 3), single-sided deafness (n = 1), and patient preference in view of difficulty using a conventional hearing aid (n = 1). In addition to the patient with single-sided deafness, 3 patients had a bilateral mixed hearing loss and 1 had a bilateral conductive hearing loss...

Chronic otitis media is a major contributor to acquired hearing loss in developing countries. Developing countries such as India, with huge populations and poor health infrastructures, have always felt the shortage of trained specialists who can provide quality care to meet the enormous demand for treatment of this disease. This pilot study assessed the feasibility of empowering trained health workers equipped with ENTraview, a store-and-forward telemedicine device that integrates a camera- enabled smart phone with an otoscope...

Cochlear synaptopathy can result from various insults, including acoustic trauma, aging, ototoxicity, or chronic conductive hearing loss. For example, moderate noise exposure in mice can destroy up to ∼50% of synapses between auditory nerve fibers (ANFs) and inner hair cells (IHCs) without affecting outer hair cells (OHCs) or thresholds, because the synaptopathy occurs first in high-threshold ANFs. However, the fiber loss likely impairs temporal processing and hearing-in-noise, a classic complaint of those with sensorineural hearing loss...

OBJECTIVES: The goal of this study was to investigate the use of transient-evoked otoacoustic emissions (TEOAEs) and middle ear absorbance measurements to monitor auditory function in patients with cystic fibrosis (CF) receiving ototoxic medications. TEOAEs were elicited with a chirp stimulus using an extended bandwidth (0.71 to 8 kHz) to measure cochlear function at higher frequencies than traditional TEOAEs. Absorbance over a wide bandwidth (0.25 to 8 kHz) provides information on middle ear function...

PURPOSE OF REVIEW: Auditory neuropathy spectrum disorder (ANSD) is a condition in which auditory testing reveals normal otoacoustic emissions, but auditory brainstem testing is abnormal or absent and speech discrimination is poor. This constellation of findings ostensibly suggests that the cochlea is healthy and an abnormality of conduction or processing of sound occurs along the nerve fibers. As more is learned about this condition, it is becoming clear that ANSD describes heterogeneous, distinct clinical entities that must be taken into account when devising treatment modalities...

A pontine hemorrhage can evoke several neurological symptoms because the pons contains various nuclei and nerve fibers. Hearing loss can develop as a result of a pontine hemorrhage because there is an auditory conduction pathway in the cochlear nucleus of the pons. However, very few cases of hearing loss caused by pontine lesions have been reported, and there have been no reports of auditory neuropathy that developed following a pontine hemorrhage. Recently we had a patient who experienced a nontraumatic pontine hemorrhage who was diagnosed with auditory neuropathy...

OBJECTIVE: Compared to basic-feature hearing aids, premium-feature hearing aids have more advanced technologies and sophisticated features. The objective of this study was to explore the difference between premium-feature and basic-feature hearing aids in horizontal sound localization in both laboratory and daily life environments. We hypothesized that premium-feature hearing aids would yield better localization performance than basic-feature hearing aids. DESIGN: Exemplars of premium-feature and basic-feature hearing aids from two major manufacturers were evaluated...

BACKGROUND: The primary aim of newborn hearing screening is to detect permanent hearing loss. Because otoacoustic emissions (OAEs) and automated auditory brainstem response (AABR) are sensitive to hearing loss, they are often used as screening tools. On the other hand, false-positive results are most often because of transient outer- and middle ear conditions. Wideband acoustic immittance (WAI), which includes physical measures known as reflectance and absorbance, has shown potential for accurate assessment of middle ear function in young infants...

OBJECTIVE: We investigated the factors influencing speech perception in babble for 5-year-old children with hearing loss who were using hearing aids (HAs) or cochlear implants (CIs). DESIGN: Speech reception thresholds (SRTs) for 50% correct identification were measured in two conditions - speech collocated with babble, and speech with spatially separated babble. The difference in SRTs between the two conditions give a measure of binaural unmasking, commonly known as spatial release from masking (SRM)...

Introduction  Neuroendocrine adenomas of the middle ear (NAME) are uncommon causes of middle ear masses. Mostly limited to case reports and small series, the literature is poor in providing an overall assessment of these tumors. Objective  To review the current literature about all aspects of the disease, including its etiology, clinical manifestations, diagnosis, and treatment. Data Synthesis  The pathogenesis of adenomatous tumors of the middle ear is not clear yet. One potential explanation is that an undifferentiated pluripotent endodermal stem cell may still be present in the middle ear mucosal surface, and may be the origin of the tumors...
