“…The significantly higher static acoustic peak admittance values (p<0.01; t test with pooled variance) for boys in the normative sample can primarily be attributed to the difference in middle ear and tympanic membrane sizes for female and male ears 22 . This difference highlights the consideration of gender in establishing normative high frequency tympanometry data.…”

Conclusion. High frequency immittance measurements demonstrate promise in clarifying middle ear status for neonates but age-and gender-specific norms should be consulted. Objective. To describe high frequency immittance measurements using a 1000 Hz probe tone for a sample of 278 neonatal ears (0-4 weeks of age) in order to compile normative tympanometric and acoustic reflex criteria. Subjects and methods. Assessment of neonatal ears included 1000 Hz probe tone immittance measurements (tympanograms and ipsilateral acoustic reflexes), and distortion product oto-acoustic emission (DPOAE) screening. Results were compared and normative values were compiled for immittance measures in ears controlled for normal middle ear functioning (n=250). Results. Comparison of immittance results to OAE screening outcome provides estimates of sensitivity and specificity for middle ear fluid with tympanometry of 57% and 95%, and 57% and 90% for acoustic reflex presence, and 58% and 87% for combined tympanogram and acoustic reflex results, respectively. Normative data indicate that static peak admittance values differ significantly across gender and age with the 5th percentile cut-off value for the entire sample at 1.4 mmho. The 90% range of tympanic peak pressure normative values increases with increasing age from 140 daPa for neonates 1 week of age to 210 daPa for neonates 2-4 weeks of age. Acoustic reflexes were elicited at 93±9 dB with a 90% normality range of 80-105 dB.

“…Debate exists concerning the age at which standards can be applied to TM compliance. Most researchers and clinicians believe that tympanograms become reliable after 6 months of age, although this ranges from 3 or 4 months to a year [21][22][23]. Another problem with the use of tympanometry in young children is the fact that a tight seal with the probe is required for proper measurement.…”

Acute otitis media and otitis media with effusion are commonly encountered by both general practitioners and specialists. The diagnosis of otitis media requires a focused history and accurate physical examination. Unfortunately, many practitioners are either unaware of the criteria needed to make the diagnosis, or they incorrectly perform or misinterpret the physical examination. We review the pertinent historical and physical examination findings needed to accurately diagnose otitis media. Additionally, we examine the accessory tests that might help make the correct diagnosis in difficult cases. Finally, we address the issues involved in ensuring that both current and future physicians are appropriately trained in the diagnosis of this common illness.

“…Moreover, the diagnostic accuracy of OM varies depending on the physician's clinical experience. To overcome these problems, tympanometry [3] and novel optical methods such as optical coherence tomography (OCT) [4] have been used to diagnose OM. However, tympanometry has some limitations regarding diagnostic standardization and should be performed by an audiometry expert.…”
