“…Due to the this middle ear resonant hypothesis, recent studies showed multi-frequency tympanometry measurements have a better success rate than classic tympanometry measurements on revealing the middle ear effusions in infants. [7][8][9] Zhigi et al, 10 compared 226Hz-1000Hz tympanometry measurements with spiral temporal bone computerized tomography on 0-6 months infants. 1000Hz tympanometry measurements identify presence middle ear effusions with a similar concordance on computerized tomography; furthermore 1000Hz tympanometry measurements are more successful than 226Hz tympanometry measurements.…”

Objective: In this report, we aimed to compare the results and clinical performance of the 226-1000Hz multifrequency tympanometry measurements. Materials and Methods: 0-1years old 85 babies who had admitted to our otorhinolaryngology clinic were included to the study. After the clinical evaluation of the patients, all tympanometric measurements were done by an audiologist, and the results were classified and compared according to age groups. Results: In this study, 1000Hz tympanometry measurements are more sensitive than the 226Hz tympanometry measurements to discriminate the middle ear effusions. Particularly, 1000Hz tympanometry measurements are more significant on 0-6month's group. Conclusion: Tympanometry measurements are reliable methods with clinical evaluation to discriminate the middle ear effusions on 0-1 age infants. Success rate of the 1000Hz tympanometry measurements is better than 226Hz measurements to identify the middle ear effusions on this age group.

Introduction For infants under 6 months, the literature recommends 1,000-Hz tympanometry, which has a greater sensitivity for the correct identification of middle ear disorders in this population. Objective To systematically analyze national and international publications found in electronic databases that used tympanometry with 226-Hz and 1,000-Hz probe tones. Data Synthesis Initially, we identified 36 articles in the SciELO database, 11 in the Latin American and Caribbean Literature on the Health Sciences (LILACS) database, 199 in MEDLINE, 0 in the Cochrane database, 16 in ISI Web of Knowledge, and 185 in the Scopus database. We excluded 433 articles because they did not fit the selection criteria, leaving 14 publications that were analyzed in their entirety. Conclusions The 1,000-Hz tone test has greater sensitivity and specificity for the correct identification of tympanometric curve changes. However, it is necessary to clarify the doubts that still exist regarding the use of this test frequency. Improved methods for rating curves, standardization of normality criteria, and the types of curves found in infants should be addressed.

“…Anatomical differences, such as underdevelopment and collapse of the Eustachian tubes [17], along with mid-facial hypoplasia causing relatively small post nasal space meaning that normal sized adenoidal tissue may cause Eusta- then other, more sensitive, methods of measuring middle ear pressure could have been employed including using both 226 hz and 1000 hz probes, as standard, in very young children which have been shown to be better at detecting OME. Furthermore, there is evidence to suggest that 1000 hz probes may be more reliable in identifying middle ear effusions in children with Down syndrome compared to 226 hz probes [25]. The overall numbers within the study make definitive conclusions difficult however there is a lack of data within the literature documenting long term middle ear pressure changes within this group of patients.…”

Objective: There is debate regarding the management of otitis media with effusion (OME) in children with Down syndrome. Information about the progression of middle ear function in this group is limited. Methods: A retrospective study reviewing case notes and audiometric data of children with Down syndrome, recorded changes in middle ear pressure over time using tympanograms as a surrogate marker. Results: The first and last tympanograms of 24 children were compared along with clinical findings. 50% (12/24) with Type B tympanograms at their initial review persisted to have the same trace at follow up (42% having had at least one intervention). Overall, 25% (6/24) showed a drop in pressure group, with 4/6 having had interventions. Conclusion: Middle ear pressures in children with Down syndrome is a complex issue. Most OME will persist, which contrasts to children without Down syndrome, where up to 80% improve over a period of 3 months.
