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).

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.

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.

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 ...

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 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.
