Middle ear pressure was recorded from 396 ears and aural symptoms enquired of 198 adult subjects with seasonal allergic rhinitis. Evidence of Eustachian tube dysfunction was found in 24% of subjects. Increased duration of exposure to pollen over a further 2 weeks increased the incidence of Eustachian tube dysfunction to 48%. The development of Eustachian tube dysfunction did not correlate with the severity of nasal symptoms. 相似文献

Objective
To determine the prevalence of symptoms and signs of allergic rhinitis (AR) in children with vernal keratoconjunctivitis (VKC) and evaluate eustachian tube (ET) function using tympanometry.Methods
The patients underwent an otolaryngological examination and symptoms of rhinorrhoea, nasal obstruction, nasal itching and sneezing were evaluated for the diagnosis of AR. Tympanometry was performed by a middle ear analyzer (Impedance audiometer AZ 26, Interacoustics A/S, Assens, Denmark). Blood samples were collected for determination of peripheral blood eosinophil count (PBEC) and serum total immunoglobulin E (IgE). Allergen sensitivity was also determined by skin prick test.Results
The study included 26 males (96.3%) and 1 female (3.7%) with a mean age of 12.1 ± 4.4 years. Eight out of 27 subjects (29.6%) had blood eosinophilia and 11 out of 27 subjects had elevated serum IgE (40.7%). A positive skin prick test was identified for at least one allergen in 40% of patients (10/25 subjects). Symptoms and signs of AR were found in 10 subjects (37%). Median serum IgE level in subjects with AR (262.5 kU/L) was higher than without AR (40.2 kU/L) (p = 0.08), whereas there were no differences in PBEC or eosinophilia percentage (p > 0.05). Mean middle ear pressures in the right and left ears were −66.4 daPa (range between −268 and 4 daPa) and −57.3 daPa (range between −308 and 0 daPa), respectively. The tympanometry results were abnormal in 5 subjects (18.5%) (3 type C and 2 type B tympanogram). Three out of 10 VKC patients with AR (30%) and 2 out of 17 VKC patients without AR (11.8%) had abnormal tympanograms (p = 0.33).Conclusion
AR is commonly associated with VKC and subjects with AR are almost three times more likely to have ET dysfunction than those without. Therefore, opthalmologists should refer VKC patients to otolaryngologists to delineate associated AR and ET dysfunction. Conversely, patients with OME and/or AR who have persistent allergic eye symptoms may well benefit from opthalmologic evaluation for seasonal allergic conjunctivitis and VKC. 相似文献13.

Objective
Tympanometry is a relatively simple method to assess middle ear (ME) status and pressure. Daily, serial tympanometric measurements may contain information on the constitutional efficiency of Eustachian tube function (ETF). A study was conducted to determine family compliance with an effort-intensive protocol that requires daily tympanometry done on each child, daily symptom recording by a parent and weekly visits with study personnel and to abstract measures that summarize the data as they relate to ETF.Methods
Longitudinal 6-month, daily follow-up on 249 children from 123 families by parent-recorded bilateral tympanometry and cold-like illnesses.Results
Study attrition was minimal with 90% of the enrolled families completing 90% of the study period. Parental compliance with daily tympanometry was less. Overall, 67% of the families were 80% compliant and 51% were 90% compliant. Two measures (aMEP, average middle ear pressure; vMEP, standard deviation of MEP) were evaluated for summaries of the longitudinal tympanometric results. These measures were not bilaterally independent or mutually independent and were affected by cold-burden and age. The best summary measure of constitutional ET efficiency may be a dimensional map of vMEP on aMEP with subsequent subdivision of the dimensional space into zones with functional interpretations.Conclusion
Long-term studies that require daily parental recording of tympanometry and the presence/absence of cold-like illness are feasible. It is expected that compliance with the required procedures can be increased substantially by pre-selection of candidate families. Preliminary data analyses suggest that the longitudinal tympanometric data contains important information on constitutional ETF. 相似文献17.
One important role of the Eustachian tube is to protect the middle ear from the extensive physiological pressure variations that take place in the nasopharynx, for example on sniffing. In a previous investigation in 50 children with persistent middle ear effusion a surprisingly high percentage of ears were evacuated by sniffing. The present study was undertaken in a second series of children, and results were found to be reproducible. In total 156 ears in 100 children have been investigated. In 63% of ears (73% of subjects) evacuation of the middle ear took place on sniffing. Results show that Eustachian tube malfunction in these subjects is characterized by a reduced protective function; a condition denoted "Eustachian tube closing failure". 相似文献

Few objective measures exist to predict the outcome of ear surgery. Clinical and experimental experience has shown the key role of the Eustachian tube in this respect, but clinical testing is seldom performed. The present study confirms that Eustachian tube testing may be of clinical significance by comparing preoperative test results before myringoplasty with the late results of this operation. In 157 patients the ability to equilibrate a static air pressure of plus or minus 200 mm of water passively or actively was tested. It turned out that in those 15% who could equilibrate minus 200 mm passively a 7 times higher rate of succssful myringoplasty was found. Ears with cholesteatoma showed less ability to equilibrate actively. Despite these findings it is concluded that the present tests are insufficient for clinical use. 相似文献
