Evaluation of Noise-Induced Hearing Loss in Young People

Using a Web-Based Survey Technique.

Author(s): Chung, J. H., Des Roches, C. M., Meunier, J., Eavey, R. D. Source: Pediatrics. 115(4):861-867. April 2005. Availability: Available from American Academy of Pediatrics. 141 Northwest Point Boulevard, Elk Grove Village, IL 60007-1098. (888) 227- 1773. Fax: (847) 434- 8000. E-mail: journals@aap.org. Website: www.pediatrics.org. Language: English. Abstract: This research report gives details of a randomized study conducted with adolescents and young adults to examine the potential for hearing loss among those exposed to loud music and assess the feasibility of a Web-based survey to collect health information from this group. A 28-question survey about views toward general health issues, including hearing loss, was presented to random visitors to the MTV Website. Over a 3-day period, 9,693 Web surveys were completed. The authors report key findings that show a majority of young adults have experienced tinnitus and hearing impairment after exposure to loud music, but many of these youths could be motivated to wear ear protection.

Hearing Levels of Firefighters: Risk of Occupational Noise-

Induced Hearing Loss Assessed by Cross-Sectional and Longitudinal Data.

Author(s): Clark, W. W., Bohl, C. D. Source: The American Auditory Society: Ear and Hearing Journal. www.amauditorysoc.org. 26(3):327-340. June 2005. Availability: Available from Lippincott Williams and Wilkins. 530 Walnut Street, Philadelphia, PA 19106-3621. (215) 521-8300. Website: www.ear- hearing.com. Language: English. Abstract: The article presents details of a study conducted to learn whether firefighters are affected by occupational noise-induced hearing losses. The research team evaluated results of 12,000 audiometric tests of firefighters enrolled in hearing conservation programs at two large urban fire departments and compared them with age-matched, non- occupationally exposed groups of individuals. The results reported show that firefighters' hearing levels were as good as or better than those of an age-matched control population not exposed to occupational noise and that the decrement in hearing for individual firefighters over a 7-year period was less than that expected from presbycusis alone. The researchers concluded that firefighters do not generally experience occupational noise-induced hearing losses even though they work nonstandard hours and are sometimes exposed to high levels of noise.

Is the Middle Fossa Approach the Treatment of Choice for

Intracanalicular Vestibular Schwannoma?

633-3820. E-mail: reprints@elsevier.com. Website: www.us.elsevierhealth.com. Language: English. Abstract: This research paper summarizes a longitudinal study in which researchers compare two surgical techniques most commonly used during vestibular schwannoma (VS) surgery-the middle fossa (MF) and the retrosigmoid-transmeatal (RS-TM) routes-to preserve patients' hearing. The researchers designed this study around a series of consecutive patients operated on with the two techniques by the same surgeon. The selection criteria were tumor confined to the internal auditory canal (IAC) with a length ranging from 4 to 12 mm and hearing class A or B. Patients were alternately assigned to one of the two groups regardless of auditory class and distance of the tumor from the IAC fundus. Thirty-five subjects were operated on with the RS-TM technique and 35 via the MF route. Based on the results and findings, the researchers concluded that, though the MF approach has been described as being the better technique for VS surgery in terms of auditory results, the present longitudinal investigation shows that the MF approach does not afford any particular advantages over the RS-TM route in terms of auditory results in intracanalicular VS, with the exception of tumors reaching the IAC fundus.

Auditory Brainstem Implant (ABI): New Frontiers in Adults

and Children.

Author(s): Colletti, V. Source: Otolaryngology-Head and Neck Surgery. 133(1):126-138. July 2005. Availability: Available from Elsevier Science. (800) 654-2452. Fax: (212) 633-3820. E-mail: reprints@elsevier.com. Website: www.us.elsevierhealth.com. Language: English. Abstract: This article presents the authors' experiences with 20 adults and 9 children who were fitted with auditory brainstem implants (ABIs) between April 1997 and September 2002. The patients ranged in age from 14 months to 70 years. Ten patients had neurofibromatosis type 2 (NF2), 3 had solitary vestibular schwannoma, and 16 had various nontumor cochlear or cochlear nerve diseases. A retrosigmoid transmeatal approach was used in patients with tumors, and a retrosigmoid approach was used in nontumor patients. Correct implantation was achieved in all patients. No complications were observed as a result of implantation surgery or related to ABI activation or long-term use. Auditory sensations were induced in all patients with various numbers of electrodes. Different pitch sensations were identifiable with different electrode stimulation. The article presents closed-set word recognition, open-set sentence recognition, and speech tracking scores achieved by the patients. The auditory performance of the patients in this study was significantly better than those achieved in the control group from the Multiethnic European clinical investigations of ABI with NF2. The authors conclude that the indications for the ABI can be extended to include nontumor patients with severe cochlear or cochlear nerve abnormalities. 2 figures. 50 references. (AA-M).
