Active clinical trials for "Hearing Disorders"

Early detection of hearing affection in call center operators Study the effect of this type of noise on the auditory brainstem response.

Balance and weak postural control are most common in children with severe to profound hearing deficits. Children with hearing deficits also indicate behavioral problems related to impulse control, distraction, and disability to maintain attention in the visual modality. Hearing deficit is mostly defined as a communication deficit. Although the communication deficit is an important disorder, hearing deficit co-occurs with other physical impairments such as vestibular disorders. Development and control of the posture are important prerequisites for skill motor function. Children with hearing deficits and impaired sensory organization had weak balance and motor efficiency in many fields. Various studies on motor skills in deaf children have reported deficits in balance, general dynamic coordination, visual-motor skills, ball catching ability, and some disturbances in reaction time and speed of movements. Teachers of children with hearing impairment often complain of non-coordination, clumsiness, and balance deficit in such children, preventing the child from the desired function. So the aim of the study is to determine the effects of Cawthorne Cooksey Exercises on Balance and quality of life in children with hearing deficit It will be a Randomized Controlled Trial and children fulfilling exclusion-inclusion criteria will participate in the study. They will be divided randomly into two groups, using computer generated randomization, into control group and experimental group. After performing the pre-test measurements, the control group will perform Swiss Ball Exercises for 45 minutes and the interventional group will perform Cawthorne Cooksey Training Program Swiss Ball Exercises in addition, will also perform of 45 min session three times a week for 8 weeks of training. the study subjects will be evaluated again by Pediatrics Berg Balance Scale, Four-Step Square test and Quality of life questionnaire for children to measure the quality of life. Results will be compared with the pretest measurements. Data will be analyzed by using SPSS scale windows software version 25.

The purpose of this study is to determine whether ancrod is effective and safe in the treatment of sudden sensorineural hearing loss (SSHL).

This is a prospective within-subjects repeated-measures study that will enroll 24 adult users implanted with a HiResolution Bionic Ear System (HiRes 90K or newer). Subjects will be assigned to one of two cohorts based on audiometric results at the Baseline visit

This is a prospective within-subjects repeated-measures study that will enroll 17 users 13 years or older implanted with a HiResolution Bionic Ear System.

The purpose of this study is to determine whether chronic electrical stimulation of the primary auditory cortex is effective in the treatment of chronic, severe and intractable tinnitus

The purpose of this feasibility study is to evaluate the benefit of unilateral implantation in adults who have severe to profound sensorineural hearing loss in one ear, and up to moderate sensorineural hearing loss in the other ear (asymmetric hearing loss).

The overall aim of the study is to investigate the Ponto wide implant considering; initial implant stability, stability over time, skin reaction and long term success when loaded at 3 weeks post surgery. Patients' quality of life improvements following implantation will also be surveyed. More specifically the primary objective of this clinical study is to test the hypothesis The new Ponto wide diameter implant offers increased implant stability measured as ISQ (implant stability quotient) compared to the previous generation Ponto implant. And the secondary objective is to Investigate when in time implant stability is the lowest as the initial mechanical stability is gradually replaced by biological stability

The objective of this study is to compare remote and in-person audiological cochlear implant candidacy evaluations (including audiological (hearing) testing and counseling sessions) in a rural Appalachian region.

Perioperative hearing loss is a rarely reported phenomenon. However, it occurs more frequently than most anaesthesiologists suspect. Perioperative hearing impairment is often subclinical and may go unnoticed unless audiometry is performed. It can be conductive or sensorineural, unilateral or bilateral, and transient or permanent. Hearing loss has been reported following virtually every type of anaesthetic technique. The hearing mechanism may be less susceptible to acoustic trauma during general anaaesthesia. But other mechanisms are capable of causing both conductive and sensorineural hearing losses (SNHL) in the perioperative period. The aetiologies include mechanical, traumatic, noise-induced, changes in cerebrospinal fluid (CSF) pressure, embolism, pharmacologic, and other miscellaneous causes. Stress may influence central vestibular function in health and disease either directly through the actions of glucocorticoids (cortisol and corticosterone) on ion channels and neurotransmission in the brain, or indirectly through the effects of stress-related neuroactive substances (e.g., histamine, neurosteroids) on these structures. The auditory brainstem response (ABR) provides a good estimate of the shape of the behavioral audiogram [and is thus an extremely useful tool for studying hearing sensitivity as well as the functionality of the auditory system. An awareness of the potential for and the causes of hearing loss during anesthesia may permit the anesthesiologist to prevent or minimize the risk of significant hearing deficit. The suggestion that this risk be discussed in the preoperative period with patients who are at high risk for perioperative hearing loss may be good medical-legal advice. Better understanding of the incidence, causes, and prognoses for perioperative hearing loss is essential for the anesthesiologist. Much Concern has been raised about the effects of anaesthetic drugs on cognition. Postoperative cognitive dysfunction may manifest as impairment in attention, memory, language or executive functions following surgery, and can persist for weeks, months, or more with varying severity. Such post-operative cognitive dysfunction can be quite mild and only diagnosed through psychometric assessment using specific neuropsychological tests. AIM OF THE STUDY The aim of this work is to study the possible deleterious effect of propfol versus sevoflurane on auditory and cognitive function.
