An open ear canal hearing aid system is disclosed which comprises a plurality of ear canal tubes sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds. The open ear canal hearing aid system further comprises a sound processor for amplifying ambient sounds received through ...

Care of the Ear Canal and Mastoid
Annals of Otology, Rhinology & Laryngology, 1983Zinc sulfate has been used for therapy of granulations of the trachea and ear that have not responded to usual treatment. This paper will report on current indications for zinc sulfate and the resulting success in managing granulomata of the ear canal and mastoid bowl.

An ear canal electrode for electrocochleography
Clinical Physics and Physiological Measurement, 1984The authors have been carrying out routine extratympanic electrocochleography on patients for the past five years using a small silver/silver chloride surface electrode positioned in the ear canal close to the tympanic membrane. In early recording sessions the electrode was held in position using a conductive bentonite paste (Mason et al. 1980).

How I do it: underwater endoscopic ear surgery for plugging in superior canal dehiscence syndrome.
Journal of Laryngology and Otology, 2017BACKGROUND Underwater endoscopic ear surgery does not require suction and so protects the inner ear from unexpected aeration that may damage its function in the treatment of labyrinthine fistula.

Veterinary Clinics of North America: Small Animal Practice, 1988
This discussion will focus on the clinical presentation, diagnostic evaluation, expected biologic behavior, and therapeutic options for tumours of the ear canal in the dog and cat. Particular emphasis will be placed on neoplasia of the ceruminous glands, squamous cell carcinoma, and non-neoplastic mass lesions.

Management of Ear-Canal Collapse
Archives of Otolaryngology - Head and Neck Surgery, 1982Thresholds were measured at 250, 500, 1,000, 2,000, 3,000, 4,000, 6,000, and 8,000 Hz in 20 normal adult ears and in ten ears from adults with varying amounts of ear-canal collapse. To alleviate the attenuation caused by ear-canal collapse, ear-canal inserts, postauricular pads, or circumaural cushions (Telephonics 510-020) were used with earphones ...

The Laryngoscope, 1992
AbstractAlthough cholesteatomas are more commonly found in the middle ear and the mastoid, the disease can occur in the external ear canal. All cases of ear canal cholesteatoma treated by the author were reviewed. There were nine ears in seven patients, who had an average age of 62 years.

Ear Canal Signal Converting Method, Ear Canal Transducer and Headset
The Journal of the Acoustical Society of America, 2012A method of converting electrical signals into mechanical vibration by means of a transducer in the human ear, an ear canal transducer and a headset wherein a sensation of hearing is achieved by exciting the tissue of the ear canal directly with said transducer, whereby the vibrations propagate to the tympanic membrane and into the human sound sensing ...

The effect of middle ear resonant frequency, ear canal resonance, and ear canal volume on TEOAE
The Journal of the Acoustical Society of America, 1998It is well known that there is a large inter-individual variability in the size of the TEOAE. Quantifying the sources of variability can help to determine the influences of some of the factors that can affect test results. The difference found in TEOAE may be due to the difference in size and shape of the ear rather than cochlear mechanics.
