UNLABELLED Characteristics of how external and middle ear resonance frequency can impact the capture of otoacoustic emissions. AIM to study the impact of external and middle ear resonance frequency in otoacoustic emissions. STUDY DESIGN Prospective, clinical, series study. MATERIALS AND METHODS Microphone-probe measurements were made in the external ear, together with multifrequency timpa...

INTRODUCTION We describe indications and surgical technique for dividing the stapedius and tensor tympani tendons during middle ear surgery. Middle ear muscle reflexes involve contraction of the tensor tympani muscle (TTM) and stapedius muscle (SM) to increase impedance of the middle ear, and may shield the inner ear from loud, continuous nonimpact noise. Sectioning SM and TTM tendons has been ...

This report describes the CT and MR findings in one patient with a spontaneous middle ear meningocele and a second patient with a middle ear meningoencephalocele possibly related to a large intracranial mass. High-resolution CT defined anatomic relation and bone destruction, and MR aided in tissue characterization.

Retention within the middle ear cleft is an unusual complication of T-tube insertion. A 40-year-old woman with Kartagener's Syndrome presented with hearing impairment in the right ear. She was found to have a previously inserted Goode T-tube lying within the middle ear behind an intact drum. She underwent successful removal of the T-tube via a myringotomy, and a new tube was re-inserted. Migrat...

The inner ear, composed of the cochlea and the vestibule, is a specialized sensory organ for hearing and balance. Although the inner ear has been known as an immune-privileged organ, there is emerging evidence indicating an active immune reaction of the inner ear. Inner ear inflammation can be induced by the entry of proinflammatory molecules derived from middle ear infection. Because middle ea...

Accurate diagnosis of most middle ear pathological conditions including otitis media remains challenging in a clinical setting. Standard ear evaluations are still performed primarily on the basis of human recognition of morphologic patterns in vivo using white light otoscope and suffer from significant observer variability providing minimal understanding of a disease’s underlying biochemistry. ...

Otitis media and other middle ear diseases are extremely common among all children worldwide. Chronic otitis media is strongly associated with the presence of a bacterial middle ear biofilm, which if left untreated, may result in hearing loss or delays in the development of speech and language. Many animal models and methods used to study the progression of various middle ear diseases exist. Ho...
