An experimentally informed computational model of neurovestibular adaptation to altered gravity
Experimental Physiology, EarlyView.Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Congenital Anomalies of the Ear Canal
Otolaryngologic Clinics of North America, 2023Congenital anomalies of the external auditory canal (EAC) are classically divided into congenital aural atresia (CAA) and congenital aural stenosis (CAS). CAA can present as an isolated anomaly, unilateral or bilateral, or in the setting of a craniofacial syndrome. Hearing testing (ABR with air and bone conduction thresholds for both ears) early in the

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

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.

Atresia of the External Ear Canal
Archives of Otolaryngology - Head and Neck Surgery, 1956INTRODUCTION Atresia of the external ear canal may be congenital or acquired. Congenital atresia presents a more complex problem. If it is bilateral, a severe hearing impairment exists from birth, with consequent tardy development of the child. A speech defect is coexistent.

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 ...
