OBJECTIVES The aim of this study was to evaluate and report the long-term results of the butterfly cartilage tympanoplasty. Short-term and long-term hearing outcomes were compared according to age and perforation location as well. METHODS Ninety-three patients who were diagnosed with noncomplicated chronic otitis media and underwent microscopic transcanal butterfly cartilage tympanoplasty due...

I. POLICY TOP Semi-implantable and fully implantable middle ear hearing aids are considered investigational. There is insufficient evidence to support a conclusion concerning the health outcomes or benefits associated with this procedure. Cross-Reference MP-1.019 Implantable Bone Conduction and Bone-Anchored Hearing Prosthetic Devices MP-1.023 Cochlear Implants MP-1.085 Auditory Brain Stem Impl...

OBJECTIVE The goal of this study was to investigate, in hearing-impaired participants who could not hear the stimuli, the possibility of artifactual auditory steady-state responses (ASSRs) when stimuli are presented at high intensities. DESIGN ASSRs to single (60 dB HL) and multiple (20 to 50 dB HL; 500 to 4000 Hz) bone-conduction stimuli as well as single 114 to 120 dB HL air-conduction stim...

A bone conduction (BC) sound presented on either side of the head will travel to cochleae in both ears, and this crosstalk phenomenon is considered one factor limiting benefits binaural hearing with BC. Previous studies have demonstrated feasibility measuring phase level required for cancellation at cochlea; however, given a human subject’s inability consistently detect low frequencies, ...

Objective: This study was focused on the assessment of patient’s improvement in hearing, as measured by pure tone audiometry after stapedotomy for primary otosclerosis. Materials and Methods: prospective clinical performed a total 156 patients diagnosed with Primary Otosclerosis, who underwent Stapedotomy at Department ENT & Head-Neck Surgery, Combined Military Hospital Dhaka between Januar...

Congenital external auditory canal atresia is a disorder with a prevalence of one in 10 000-20 000 live births and is bilateral in one third of the patients. With a conductive hearing loss of 60 dB, even unilateral atresia restricts hearing related social skills. The degree of middle ear deformity may make reconstruction surgery impossible or too hazardous, thus bone-conduction hearing aids hav...

Introduction  Diode laser is a new alternative in stapes surgery for otosclerosis. The present study is the first to compare the short-term results of the surgery performed using diode laser to those obtained through the conventional fenestration technique. Objective  To use audiometry to establish a comparative analysis between the functional results obtained through surgery for otosclerosis u...

BACKGROUND Bone conduction (BC) threshold depression is not always by means of sensory neural hearing loss and sometimes it is an artifact caused by middle ear pathologies and ossicular chain problems. In this research, the influences of ear surgeries on bone conduction were evaluated. MATERIALS AND METHODS This study was conducted as a clinical trial study. The ear surgery performed on 83 pa...

INTRODUCTION AND OBJECTIVES Minimising false positives rates is an important goal of universal newborn hearing screening programmes. An adequate way for reaching that goal could be differentiating between transient conductive hearing losses (false positives) and permanent sensorineural hearing impairments (true positives) by means of a methodology that studies electrophysiological responses obt...
