The middle ear ossicles are important due to transmission of sound to the inner ear leading to sound understanding. The aim of present study was to determine the anatomical and morphometrical aspects of middle ear ossicles in Makouei sheep fetuses. For this experimental study, eight sheep fetuses at the age of 2 to 3 months were provided from public slaughterhouse; their middle ear ossicles wer...

PURPOSE The purpose of this study was to evaluate Interaural Attenuation (IA) in frequency base in the insert earphones that are used in audiological assessments. METHODS Thirty healthy subjects between 18-65 years of age (14 female and 16 male) participated in our study. Otoscopic examination was performed on all participants. Audiological evaluations were performed using the Interacoustics ...

Involvement of the ossicular chain by temporal bone disease can seldom be evaluated adequately on routine axial and coronal CT views [1-5]. Direct sagittal tomography views delineate these structures clearly [6, 7], but CT views require considerable manipulation of cooperative patients and are seldom reproducible in the exact planes in repeated examinations [8, 9]. High-resolution lateral obliq...

INTRODUCTION AND OBJECTIVE Many designs of prostheses are available for middle ear surgery. In this study we propose a design for a new prosthesis, which optimises mechanical performance in the human middle ear and improves some deficiencies in the prostheses currently available. Our objective was to design and assess the theoretical acoustic-mechanical behaviour of this new total ossicular rep...

Introduction. Rheumatoid arthritis (RA) can involve the incudomalleolar or incudostapedial articulations. Objective. To know the punctual prevalence of audiological alterations in patients with RA. Patients and Methods. RA patients and their controls (Cs), were evaluated by Tonal Audiometry (AU); if there were alterations in the air conduction (AC), bone conduction (BC), Logoaudiometry (LG), an...

The story of the evolution of hearing in land vertebrates is fascinating but complex. The water-to-land transition changed the physical environment in which hearing happens so dramatically that both the peripheral receptor structures and the central auditory circuits underwent a revolution, leading to the sensitive hearing of higher-frequency airborne sound. This (r)evolution took a very long t...

The aim of this study is to present various morphologic aspects of the middle ear cholesteatoma, concerning both container (tympanic cavity) and content (cholesteatoma). There are two different aspects of the study: a mezoscopic study of the tympanic walls and the elements within the middle ear (ossicular chain, folds, ligaments, middle ear clefts) in order to evidentiate the critical areas (si...

OBJECTIVES To report the rare case of a patient with complete incus dislocation after trauma showing normal hearing. METHODOLOGY Physical examination, audiometry, CT of temporal bone, and detection during operation. RESULTS The incus had become remotely located in the mastoid cavity, but the patient showed normal hearing because fibrous connections had preserved bony continuity. CONCLUSIO...

Abstract Background Current classifications emphasize the morphology of coalition, however, subtalar joint facets involved should also be emphasized. Objective The objective this study was to develop a new classification system based on articular cover all coalitions and guide operative planning. Methods Patients were diagnosed with talocalcaneal coalition using CT scan, between January 2009 Fe...
