experiential instruction in graduate level preparation of speech language pathology students in outer and middle ear screening
American Journal of Speech-language Pathology, 2015Co-Authors: Yula C Serpanos, Deborah SenzerAbstract:Purpose This study presents a piloted training model of experiential instruction in outer and middle ear (OE-ME) screening for graduate speech-language pathology students with peer teaching by doctor of audiology (AuD) students. Method Six individual experiential training sessions in screening otoscopy and Tympanometry were conducted for 36 graduate-level speech-language pathology students led by a supervised AuD student. Results Postexperiential training, survey outcomes from 24 speech-language pathology students revealed a significant improvement (p = .01) in perceptions of attaining adequate knowledge and comfort in performing screening otoscopy (handheld and video otoscopy) and Tympanometry. In a group of matched controls who did not receive experiential training in OE-ME screening (n = 24), ratings on the same learning outcomes survey in otoscopy and Tympanometry were significantly poorer (p = .01) compared with students who did receive experiential training. Conclusion A training model of experienti...

Tympanometry.
American family physician, 2004Co-Authors: Edward OnuskoAbstract:Tympanometry provides useful quantitative information about the presence of fluid in the middle ear, mobility of the middle ear system, and ear canal volume. Its use has been recommended in conjunction with more qualitative information (e.g., history, appearance, and mobility of the tympanic membrane) in the evaluation of otitis media with effusion and to a lesser extent in acute otitis media. It also can provide useful information about the patency of tympanostomy tubes. Tympanometry is not reliable in infants younger than seven months because of the highly compliant ear canals of infants. Tympanogram tracings are classified as type A (normal), type B (flat, clearly abnormal), and type C (indicating a significantly negative pressure in the middle ear, possibly indicative of pathology). According to the Agency for Healthcare Research and Quality guidelines on otitis media with effusion, the positive predictive value of an abnormal (flat, type B) tympanogram is between 49 and 99 percent. A type C curve may be useful when correlated with other findings, but by itself it is an imprecise estimate of middle ear pressure and does not have high sensitivity or specificity for middle ear disorders.

distortion product otoacoustic emissions in children at school entry a comparison with pure tone screening and Tympanometry results
Journal of The American Academy of Audiology, 2004Co-Authors: April Lyons, Joseph Kei, Carlie DriscollAbstract:This study examined the test performance of distortion product otoacoustic emissions (DPOAEs) when used as a screening tool in the school setting. A total of 1003 children (mean age 6.2 years, SD = 0.4) were tested with pure-tone screening, Tympanometry, and DPOAE assessment. Optimal DPOAE test performance was determined in comparison with pure-tone screening results using clinical decision analysis. The results showed hit rates of 0.86, 0.89, and 0.90, and false alarm rates of 0.52, 0.19, and 0.22 for criterion signal-to-noise ratio (SNR) values of 4, 5, and 11 dB at 1.1, 1.9, and 3.8 kHz respectively. DPOAE test performance was compromised at 1.1 kHz. In view of the different test performance characteristics across the frequencies, the use of a fixed SNR as a pass criterion for all frequencies in DPOAE assessments is not recommended. When compared to pure tone plus Tympanometry results, the DPOAEs showed deterioration in test performance, suggesting that the use of DPOAEs alone might miss children with subtle middle ear dysfunction. However, when the results of a test protocol, which incorporates both DPOAEs and Tympanometry, were used in comparison with the gold standard of pure-tone screening plus Tympanometry, test performance was enhanced. In view of its high performance, the use of a protocol that includes both DPOAEs and Tympanometry holds promise as a useful tool in the hearing screening of schoolchildren, including difficult-to-test children.

outcomes of transient evoked otoacoustic emission testing in 6 year old school children a comparison with pure tone screening and Tympanometry
International Journal of Pediatric Otorhinolaryngology, 2001Co-Authors: Carlie Driscoll, Joseph Kei, Bradley McphersonAbstract:Objectives: (1) To establish test performance measures for Transient Evoked Otoacoustic Emission testing of 6-year-old children in a school setting; (2) To investigate whether Transient Evoked Otoacoustic Emission testing provides a more accurate and effective alternative to a pure tone screening plus Tympanometry protocol. Methods: Pure tone screening, Tympanometry and transient evoked otoacoustic emission data were collected from 940 subjects (1880 ears), with a mean age of 6.2 years. Subjects were tested in non-sound-treated rooms within 22 schools. Receiver operating characteristics curves along with specificity, sensitivity, accuracy and efficiency values were determined for a variety of transient evoked otoacoustic emission/pure tone screening/Tympanometry comparisons. Results: The Transient Evoked Otoacoustic Emission failure rate for the group was 20.3%. The failure rate for pure tone screening was found to be 8.9%, whilst 18.6% of subjects failed a protocol consisting of combined pure tone screening and Tympanometry results. In essence, findings from the comparison of overall Transient Evoked Otoacoustic Emission pass/fail with overall pure tone screening pass/fail suggested that use of a modified Rhode Island Hearing Assessment Project criterion would result in a very high probability that a child with a pass result has normal hearing (true negative). However, the hit rate was only moderate. Selection of a signal-to-noise ratio (SNR) criterion set at greater than or equal to 1 dB appeared to provide the best test performance measures for the range of SNR values investigated. Test performance measures generally declined when Tympanometry results were included, with the exception of lower false alarm rates and higher positive predictive values. The exclusion of low frequency data from the Transient Evoked Otoacoustic Emission SNR versus pure tone screening analysis resulted in improved performance measures. Conclusions: The present study poses several implications for the clinical implementation of Transient Evoked Otoacoustic Emission screening for entry level school children. Transient Evoked Otoacoustic Emission pass/fail criteria will require revision. The findings of the current investigation offer support to the possible replacement of pure tone screening with Transient Evoked Otoacoustic Emission testing for 6-year-old children. However, they do not suggest the replacement of the pure tone screening plus Tympanometry battery. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.

Progression of Tympanometry and Acoustic Reflectometry Findings in Children With Acute Otitis Media
Clinical pediatrics, 1994Co-Authors: Thomas R. Babonis, Michael R. Weir, Patrick C. Kelly, Marvin S. KroberAbstract:The presence of middle ear effusion (MEE) following acute otitis media (AOM) has been assessed by impedance Tympanometry and acoustic reflectometry but has not been assessed serially from the time of presentation for AOM in the same group of patients. This descriptive study examined serial measurements by Tympanometry and reflectometry in children with clinical AOM at the time of diagnosis, 3 to 5 days later, and at final follow-up 12 to 15 days after diagnosis. The study entry criteria were conservative in order to represent obvious cases of AOM and included 90 patients representing 107 ears. The objective was to describe the evolution of instrumental findings and to attempt to identify unique patient subpopulations with differing prognoses. We found that combined use of initial Tympanometry and reflectometry, while yielding intriguing results, does not allow for identification of subpopulations with good or poor progression for MEE clearance at 2-week follow-up. It is our conclusion that initial Tympanometry and reflectometry add to the cost of AOM diagnosis without clear benefit for the individual patient.

Impedance Tympanometry and Acoustic Reflectometry at Myringotomy
Pediatrics, 1991Co-Authors: Thomas R. Babonis, Michael R. Weir, Patrick C. KellyAbstract:A total of 220 ears undergoing myringotomy and pressure-equalizing tube placement were studied with impedance Tympanometry and acoustic reflectometry in a direct comparison for detection of middle-ear effusion. Impedance Tympanometry and acoustic reflectometry were equally accurate, detecting the presence or absence of middle-ear effusion in 73% and 72% of ears, respectively. The presence of effusion in ears with tympanographic patterns other than type A and type B was not consistently and reliably predicted. The higher sensitivity of impedance Tympanometry (90%) compared with that for acoustic reflectometry (58%) contrasted with the opposite findings for specificities (54% vs 88%). It is concluded that impedance Tympanometry and acoustic reflectometry measure different events at the tympanic membrane and their utility lies in the fact that they complement each other. These instruments can aid the experienced otoscopist in confirming a clinical impression and assist the less experienced clinician in validating or improving otoscopic skills.
