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.

Reconstruction of Ear Canal in Surgery for Chronic Ear
Archives of Otolaryngology - Head and Neck Surgery, 1962Tympanoplastic procedures have now been practiced for more than 10 years, and most of the surgical methods are already well standardized. Excellent descriptions of different alternatives are given in textbooks on ear surgery by Shambaugh 1 and by Portmann, Portmann, and Claverie.

A decrease in air conduction sensitivity may be produced in some individuals by pressure exerted on the pinna during audiometric testing. The pressure of the earphone against the pinna may result in the partial closure or complete collapse of the external auditory meatus.

Otoscopic evaluation of the ear canal
Veterinary Clinics of North America: Small Animal Practice, 2004Otoscopic evaluation of the external ear canal and tympanic membrane is the first diagnostic procedure that should be performed in animals presented with otitis externa. It is important to become familiar with the normal structures of the ear to identify any abnormalities. The video otoscope greatly enhances visualization of these structures as well as

Ear and Hearing, 1981
The effects of collapse of the external ear canals due to pressure from earphones have been documented and discussed by several authors during the past 2 decades. This report presents a case of ear canal collapse in a child and demonstrates the value of impedance audiometry in cases of collapse of the external ear canal.

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 ...

Ear Canal Hyperostosis—Surfer's Ear
Archives of Otolaryngology, 1977The increased populatiry of surfing has produced a marked augmentation in the incidence of ear canal exostosis. However, when it becomes moderately severe, I prefer to call it "hyperostosis." Exposure to cold ocean water for many years can be an important etiologic factor in hyperostosis.

The Journal of the Acoustical Society of America, 2000
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 ...
