Ossicular calisthenics: Pneumomassage of the tympanic membrane.
OBJECTIVES/HYPOTHESIS Throughout the latter portion of the 19th and early 20th centuries, pneumomassage devices were widely used by otologists to treat a variety of ear diseases. The so-called eardrum massagers produced a regular, repetitive, oscillatory movement through modifying the air pressure in the ear canal. The goal of this study was to trace the invention, clinical use, technological d...
متن کاملEustachian tube function in adults with intact tympanic membrane.
UNLABELLED The Eustachian tube has the function of equilibrating the environmental pressure with inner pressure, protecting the middle ear from abrupt pressure changes. AIM To compare the Eustachian tube function in adults with and without history of otitis media and/or respiratory tract inflammation without tympanic membrane perforation. MATERIALS AND METHODS The Eustachian tube function w...

Methods: We conducted a retrospective chart review of all patients consecutively referred to the senior authors at a tertiary-care Pediatric Otolaryngology clinic for fi rst branchial cleft anomalies over a 14-year period. Patients underwent computerized tomography scan with contrast, otoscopy plus tympanic microsurgery, when indicated (29%), methylene blue mapping of the cutaneous opening, whe...
متن کاملFeasible pickup from intact ossicular chain with floating piezoelectric microphone
OBJECTIVES Many microphones have been developed to meet with the implantable requirement of totally implantable cochlear implant (TICI). However, a biocompatible one without destroying the intactness of the ossicular chain still remains under investigation. Such an implantable floating piezoelectric microphone (FPM) has been manufactured and shows an efficient electroacoustic performance in vit...
متن کاملPreoperative evaluation of ossicular chain abnormality in patients with conductive deafness without perforation of the tympanic membrane.
OBJECTIVE To evaluate the usefulness of pure-tone audiometry, tympanometry, and liquid and acoustic reflex (AR) tests in the differential diagnosis of ossicular fixation and discontinuity. DESIGN A prospective clinical trial. SETTING Tertiary referral center. PATIENTS Thirty-nine patients (46 ears) undergoing operations at University of Tsukuba Hospital, Tsukuba, Japan, from 1990 through ...
