Materials and Methods: This prospective study included three groups, 38 patients with Meniere’s disease (41 ears), 30 patients with cochlear hearing loss other than Meniere’s disease (40 ears) and 25 healthy subjects (40 ears). Tympanic membrane ECoG (click and tone-burst evoked) and caloric test were performed. Forty one ears with Meniere’s disease were categorized into definite (28 ears) and ...

The purpose of this investigation was to examine the effects of prolonged monaural amplification on the suprathreshold speech-recognition scores in the unaided ears of 46 persons with bilateral essentially symmetric and conductive hearing impairment and aided ears of 46 other persons with bilateral essentially symmetric and conductive hearing impairment. All subjects were less than 50 years of ...

EARS is a technique used by Rolls-Royce and many other organizations around the world to capture requirements in natural language in a precise manner. In this paper we describe the EARS-CTRL tool for writing and analyzing EARS requirements for controllers. We provide two levels of analysis of requirements written in EARS-CTRL: firstly our editor uses projectional editing as well as typing (base...

RESULTS Eighty-nine ears in 83 patients aged 7 to 85 years were included. Transmeatal tympanoplasty was performed in 17 ears (19%). Seven ears (8%) underwent tympanoplasty with canal wall–downmastoidectomy, and 65 ears (73%) underwent canal wall–up (combined approach) tympanoplasty with mastoidectomy. The study population comprised 61 primary tympanoplasties (69%) and 28 revision cases (31%). M...

OBJECTIVE To characterize audiometric findings in children with a large vestibular aqueduct (LVA). DESIGN Retrospective review. METHODS Audiometric records of children with an isolated LVA, diagnosed by computed tomography of the temporal bone, from 1995 through 1998 were reviewed. RESULTS Nineteen children had an isolated LVA in one or both ears. In all, 26 ears with an isolated LVA were...

This study prospectively analyses electrocochleography (ECoG) recordings obtained from ears demonstrating symptoms highly suggestive of Meniere's disease. Comparison is made with ECoG recording from ears in which the diagnosis of Meniere's is considered unlikely (control ears). Electrocochleograph recordings were made through a transtympanic recording needle, situated in the round window niche....

OBJECTIVES/HYPOTHESIS Pathologic third window lesions, such as superior semicircular canal dehiscence syndrome (SCDS) or large vestibular aqueduct syndrome (LVAS), cause several auditory and vestibular symptoms, which might affect perilymphatic pressure and induce endolymphatic hydrops (EH). In this study, the existence of EH in subjects with SCDS or LVAS was investigated using contrast-enhance...
