Cochlear implant is the treatment of choice for deep sensorineural hearing loss, notably in those patients for whom conventional amplification devices do not provide significant clinical improvement. Imaging plays an important role in the workup of cochlear implant candidates not only to identify
Description of the population to be studied and justification of its choice:
This study is going to include a single group of patients presenting a vestibular schwannoma that will benefit from an removal by translabyrinthine approach with exclusion from the middle ear under general anesthesia.
Velopharyngeal dysfunction is the inability to separate the oral and nasal cavities adequately during speech production through the actions of the velum and pharynx. Velopharyngeal dysfunction can be caused due to lack of tissue (velopharyngeal insufficiency) or lack of proper movement
Hypothesis The use of topical dexamethasone in a single dose applied to the tympanic cavity during cochlear implant surgery modifies the capacitive component of the electrical impedance of the electrodes in the cochlea during the first days of the postoperative period.

Study Design: A prospective randomized controlled trial of OX50 versus OX25 versus Ox75 will be conducted at Parkland Hospital. This study will test the hypothesis that the OX25 target oxygen strategy will result in successful resuscitation of preterm neonates with less O2 exposure and reduction in
Introduction Sensorineural hearing loss (SNHL) is a disability affecting people worldwide, and the prevalence is expected to increase due to prolonged life expectancy. SNHL has a significant negative impact on the quality of life, especially in prelingually deafened children. Except for certain
Adequate middle ear (ME) pressure-regulation, defined as the maintenance of a total ME pressure at approximately ambient levels, is required for normal hearing and to preserve ME health. The mechanism of ME pressure-regulation consists of two distinct components that affect total ME gas pressure:
The researcher at Beckman Laser Institute, University of California, Irvine, develops new medical tool device call biocompatible Pressure Equalizing tube which can stop air passage and pressure equalization instantly, and can prevents water into the middle ear cavity. evaluate and compare the
Prevention of Cisplatin-Induced Hearing Loss by Intratympanic Dexamethasone Treatment.
Introduction:
Cisplatin is a widely used chemotherapeutic agent for the treatment of various malignant neoplasms, including testicular, ovarian, bladder, cervix uteri, head and neck and lung cancers 1-4.
Dose
PRIMARY OBJECTIVES:
l. To determine whether the score on Instrumental Activities of Daily Living (IADL) obtained prior to treatment is associated with the ability of patients to complete four cycles of chemotherapy without dose reduction or a more than 7-day delay.
II. To estimate by regimen the
DESIGN: This is an open label, single arm, dose finding study.
STUDY PROCEDURES: Patients will receive chemotherapy and radiation for four weeks, and we will check for any problems from the treatment for 3 months. We would like to collect information from the patients regular doctor for 1 year after
