facts, as stated: about 70 percent of cases of Paget disease involve the skull, with hearing affected in approximately 50 percent of these; the hearing impairment of these patients may be sensorineural, mixed, or, rarely, only conductive; the etiology and pathogenesis of the hearing loss are not yet understood; and reports in the literature are inconsistent regarding the pathologic changes responsible for sensorineural hearing loss (SHL). The researchers studied six pairs of temporal bones from patients with Paget disease in the temporal bone collection of a research institution, two pairs of which had abnormalities not previously associated with SHL or Paget disease. The authors report the histopathologic findings in these temporal bones and conclude that cystic degeneration of the spiral ligament has not been previously reported and may be unique to Paget disease. They state also that this result is consistent with recent literature showing a previously unsuspected role of the spiral ligament in SHL. Subject Category: Hearing. Descriptors: Paget Disease.

The Use of Hearing Protectors Among Forest Shipyard and
Paper Mill Workers in Finland-A Longitudinal Study.
Author(s): Toppila, E., Pyykko, I., Starck, J. Source: Noise & Health. 7(26):3-9. January-March 2005. Availability: Address correspondence to Esko Toppila, Finnish Institute of Occupational Health, Topeliuksenkatu 41, Helsinki, Finland. E-mail: email@example.com. Language: English. Abstract: From 1953 to 1995, the usage rate of hearing protective devices (HPD) was tracked at a paper mill, at a shipyard, and in selected areas of forestry work in Finland. Key results reported showed that in the paper mill, the usage rate increased steadily from 1965; in 1990, 39 percent of workers used HPDs full-time. At the shipyard, the usage rate remained low up to the mid-1980s, but then the proportion of full-time users rose to 70 percent. A similar trend was noted in forest workers, with the full-time use at 97 percent by the 1990s. The authors find that due to these increased usage rates in all measured industries the mean effective noise level at the ear has decreased to below 85 dB. This paper presents an overview of the study and all its findings. Subject Category: Hearing. Descriptors: Noise. Workplace Health. Inside Noise. Noise Pollution. Noise Protection. Noise Usage Rate.

Abstract: This article discusses the benefits of the short electrode or hybrid cochlear implant. The authors are presenting this device as a solution to problems associated with severe high-frequency hearing loss. As explained in the article, the short electrode or hybrid implant was designed to stimulate only the basal end of the cochlea and to preserve the residual low-frequency acoustic hearing, allowing patients to hear sounds through combined acoustic plus electric stimulation. The authors see the benefit of the new device as an improvement to the lives of large numbers of individuals who, previously, had to choose either between wearing a hearing aid that was of little benefit or sacrificing the natural sounds of acoustic hearing to receive a traditional long-electrode cochlear implant.

Abstract: This article presents details of an investigation conducted to evaluate the predictive value of several parameters related to tubal dysfunction, in relation to symptomatic middle ear barotrauma in divers. The study subjects were 31 sport scuba divers with normal predive audiometry, tympanometry, and general and otorhinolaryngologic examination. After an occurrence of middle ear barotrauma, the individual diver predive data on smoking, mild septal deviation, otitis media history, rhinosinusitis history, Valsalva, Toynbee, and nine-step inflation/deflation tympanometric test, as well as degree of mastoid pneumatization, were registered for calculation of predictive value in relation to the barotrauma. The investigator examined all symptomatic ears, within 24 hours of diving, by who was blinded to the predive findings. Barotraumas that occurred during an upper respiratory tract infection were excluded. Based on the data results, the researcher concluded that Eustachian tube dysfunction measured by the nine-step test and a small size of the mastoid cell system seem to be risk factors for symptomatic middle ear barotrauma in otherwise healthy sport scuba divers. Evaluation of these factors in the predive examination of diving candidates may be useful in the determination of fitness to dive. This investigation took place at the Department of Otolaryngology, Trakya University Faculty of Medicine, Edirne, Turkey. Subject Category: Hearing. Descriptors: Middle Ear Trauma. Ear Problems.
