Central venous stenosis is a well-known complication in patients with vascular access for hemodialysis. We report two cases involving patients on hemodialysis with arteriovenous fistulas who developed reversible unilateral conductive hearing loss secondary to critical stenosis of central veins draining the arteriovenous dialysis access. A proposed mechanism for the patients' reversible unilater...

OBJECTIVE To determine whether chronic conductive hearing loss in adults results in changes in the auditory brainstem response (ABR) similar to those observed in children with histories of otitis media with effusion. DESIGN Test of effect of unilateral conductive hearing loss on adult ABR using age-matched control group and subjects as their own controls. SUBJECTS Twelve adults with a histo...

INTRODUCTION This study aims to review the results of hearing screens in newborns with cleft deformities. MATERIALS AND METHODS A retrospective audit of 123 newborns with cleft deformities, born between 1 April 2002 and 1 December 2008, was conducted. Data on the results of universal newborn hearing screens (UNHS) and high-risk hearing screens, age at diagnosis, severity/type of hearing loss ...

OBJECTIVE The aim of the investigation was to prospectively evaluate, in a multicenter setting, the clinical performance of a new magnetic bone conduction hearing implant system. METHODS The test device was the Cochlear Baha Attract System (Cochlear Bone Anchored Solutions AB, Mölnlycke, Sweden). Instead of the skin-penetrating abutment of traditional bone conduction hearing implants, the tes...

BACKGROUND It is recognized that the size of tympanic membrane perforation is proportional to the magnitude of hearing loss, however, there is no clear consensus on the effect of the location (site) of the perforation on the hearing loss. Hence the study is set to investigate the relationship between the location of perforation on TM and hearing loss. METHODS A cross-sectional prospective stu...

OBJECTIVE To demonstrate the surgical technique and audiological results of a middle ear implant for restoring hearing in patients with bilateral aural atresia and microtia with conductive or mixed hearing loss. MATERIALS AND METHODS In this prospective study, 12 subjects aged 12 years and older presenting with hearing loss and bilateral congenital aural atresia underwent surgical insertion o...

It is well known that head trauma may cause hearing loss, which can be either conductive or sensorineural. Benign paroxysmal positional vertigo and olfactory dysfunction due to head trauma are also well known. The association between sensorineural hearing loss and anosmia, following head trauma, is extremely rare. Two rare cases of post-traumatic occurrence of hearing loss, olfactory dysfunctio...

Osteoprotegerin (OPG) is a key regulator of bone remodeling. Mutations and variations in the OPG gene cause many human diseases that are characterized by not only skeletal abnormalities but also poorly understood hearing loss: Paget's disease, osteoporosis, and celiac disease. To gain insight into the mechanisms of hearing loss in OPG deficiency, we studied OPG knockout (Opg(-/-)) mice. We show...

Bone Conduction Hearing aids are used mainly for the treatment of patients who suffer from Single Sided deafness and/or Conductive/ mixed hearing loss but not Bilateral Sensorineural loss. Vibration Acoustic Stimulation is a combination both air and bone conduction at same time, four aids, two ears bilateral one aid, on defective ear single sided (SSD) Unilateral Loss. We have tried this approa...

Congenital hearing loss is estimated to affect one in every 1,000 newborns. Causes of hearing loss can be conductive, sensorineural, mixed, or central. Known risk factors for congenital hearing loss include cytomegalovirus infection and premature birth necessitating a stay in the neonatal intensive care unit. However, up to 42 percent of profoundly hearing-impaired children will be missed using...
