There are several types of eustachian tube dysfunction, including obstruction and abnormal patency. This article presents an update on several selected areas of eustachian tube function and dysfunction, including surfactants, cleft palate, tympanic membrane atelectasis, abnormal eustachian tube patency, and long-term middle ear ventilation.
Computerized dynamic platform posturography is defined in this technology assessment. The review discusses what computerized dynamic platform posturography measures, what the reliability and validity of the information are, and the uniqueness of the information provided. The clinical contribution and indications for testing are discussed. There are comments(More)
OBJECTIVE Outcomes for patients with otitis media were assessed in this prospective, multicenter study. STUDY DESIGN AND SETTING Thirty-one otolaryngologists enrolled 272 pediatric patients with otitis media; caregivers completed surveys at 3-month intervals, and clinical and treatment data was also collected. The Otitis Media 6 (OM-6) was the primary(More)
A case of functional hearing loss presenting as sudden sensorineural hearing loss in the only hearing ear of a musician is presented. Pure-tone audiometric evaluation showed good intratest and intertest consistency. The pitfalls of diagnosis, ultimately made by brain stem evoked response audiometry, are discussed in light of the literature on sudden and(More)
We have developed a unique method of quantitative computed tomography (QCT) that enables measurement of the density of the cochlear capsule in vivo. We performed pure-tone audiometry and QCT on 67 ears from 35 subjects with radiographically confirmed Paget's disease of the skull and on 40 ears from twenty volunteer subjects. The Pearson product-moment(More)
Auditory brainstem responses (ABRs) were recorded in 64 ears with radiographically confirmed Paget's disease involving the skull. Responses were absent in eight ears, all of which had elevated high pure-tone thresholds. Auditory brainstem responses were interpreted as normal in 56 ears; none were abnormal. Computed tomography and digital image analysis were(More)
Results for control of vertigo and preservation of hearing in patients who have had a retrolabyrinthine vestibular neurectomy (RVN) by our group were analyzed retrospectively. This procedure consists of selective section of the vestibular nerve in the posterior cranial fossa. Vertigo was completely controlled in all but two of 31 patients, one of whom(More)
The measurement of regional bone mineral density (rBMD) is a new method of evaluation of the human temporal bone in vitro or in vivo. Modified computed tomography (CT) enables us to collect a three-dimensional array of precise, reproducible bone density values, as well as high-quality CT images. Measurements are calibrated using phantoms of known(More)
