Bone conduction implants are indicated for patients with conductive and mixed hearing loss that do not benefit from conventional hearing aids or for those that cannot use them for anatomy abnormalities or medical conditions. These implants are also indicated for patients with single-sided deafness (SSD), which consists of one ear with profound hearing loss and the contralateral with normal hear...

OBJECTIVES To determine the prevalence, types and severity of hearing loss and associated factors in a hospital population of adult Nigerians with diabetes mellitus. SUBJECTS AND METHODS This study was a prospective hospital-based study conducted at the Otorhinolaryngology and Diabetic Clinics of the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, for a period of 12 months...

Two brothers with congenital conductive hearing loss and phenotypic characteristics of maxillofacial dysostosis are described. In the oldest boy a malformed ossicular chain was present and the conductive hearing loss was improved by a malleo-vestibulo-pexy, with post-operative hearing gain of approximately 30 dB. Although superficially similar to Treacher Collins syndrome, the facial characteri...

Petrosal cholesteatomas are rare lesions, which may be primary or acquired in nature. We report a case of primary cholesteatoma in petrous bone occurring in 51-year old woman who presented with a unilateral facial nerve palsy and conductive hearing loss, despite normal tympanic membrane appearance. Early diagnosis was facilitated by computed tomography scanning and magnetic resonance imaging. C...

OBJECTIVE To introduce a new method of measuring sound localization ability based on eye-tracking and to test this method by analysing the influence of mild induced conductive hearing loss on sound localization. DESIGN Sound signals were presented from different angles, and the participant's responses were measured using an eye-tracking device. For validation, a comparison of responses to vis...

INTRODUCTION Vestibular evoked myogenic potential (VEMP) has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC) stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients. M...

INTRODUCTION  Treacher-Collins syndrome is characterized by craniofacial malformations, narrowing of the external auditory canal (EAC), and, in 30% of cases, agenesis of the canal and ossicular chain defects. The use of hearing aids (HA) is not possible in cases in which agenesis or stenosis of the EAC accompanies conductive deafness. In contrast, bone conduction implants such as the Bone Ancho...
