External Ear Canal Cholesteatoma
Annals of Otology, Rhinology & Laryngology, 1995External ear canal cholesteatoma is a rare condition in otologic practice. A case in a 43-year-old woman is presented in which despite the extensive nature of the lesion, minimal symptoms and absence of signs delayed diagnosis. The cause of the lesion and its treatment are discussed.

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 ...

Ear Canal Keratinocyte Culture
Otology & Neurotology, 2007Autologous epidermal sheets obtained by cultivating keratinocytes of the external auditory meatus can be used to repair cutaneous defects of the ear canal. The Rheinwald and Green method has been used to know whether the produced epidermal layer preserves its specificities after the culture.Using a split-thickness skin graft during a functional ear ...

MRI scanners produce significant sound pressure levels (SPLs), sometimes in excess of 120 dBA. While the effect of these SPLs has been explored for adult patients, it is currently unknown how they affect neonatal patients. One approach to understanding the effect of this noise exposure on infants is to use existing experimental data that associates a ...

Otolaryngologic Clinics of North America, 2023
Primary EAC neoplasms include benign and malignant lesions of bony, glandular or cutaneous origin. Small, benign slow growing bony neoplasms are often asymptomatic, diagnosed incidentally and might not require intervention. Both malignant and benign neoplasms of cutaneous and glandular origin can present with symptoms of chronic otitis externa, leading

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.
