Tympanometric screening was performed in January 1976 and in August 1978 on 938 healthy three-year-old children (1,868 ears), constituting more than 95% of the total population of three-year-olds living in a Danish municipality at the time of testing. All children showing abnormalities were followed by tympanometry through the subsequent six months, or until spontaneous normalization had been ascertained. The study demonstrated a high prevalence and a common spontaneous recovery of secretory otitis media. In summer as well as in winter middle ear effusion was found in about 10% of all ears, or in every eighth child. Two thirds of the ears improved spontaneously, one third to complete normalization. Middle ear function, assessed by tympanometry, is extremely labile during the preschool years and must be evaluated from a dynamic point of view. This greatly restricts the predictive value of snapshots, such as screening results. Therefore, pending complementary information from long-term cohort studies, universal impedance screening of all preschool children should not be instituted.

Ear Effusion

To determine the prevalence, incidence, and course of secretory otitis media in an age-group population, 404 3-year-old children in a town in Denmark were examined at 6-, 8-, and 12-week intervals over a 6-month period. At each of the four examinations approximately 20% of the children had middle ear effusion (MEE); it was found at least once in 42% of the children, and 6% had persistent effusion at all four examinations. Average duration of MEE was 3 months. Since spontaneous recovery rarely occurred when MEE had been present for more than 3 months, active intervention is recommended after the condition has been followed for this length of time. The highly fluctuating course of MEE demonstrated in early childhood has important implications for concepts in pediatric middle ear disease and treatment.

AbstractIn a pilot controlled randomised trial of 38 children who had bilateral secretory otitis media, with effusion demonstrated at operation, we compared the efficacy of a six-week course of an oral decongestant—antihistamine combination and a mucolytic preparation with a control group in preventing the presence of middle-ear effusion six weeks after myringotomy and adenoidectomy. The mucolytic preparation decreased the presence of middle-ear effusion when compared to the decongestant-antihistamine combination and the control group (p=0.06).

AbstractIn order to clarify the role of mast cells in the aetiology of secretory otitis media (SOM), we compared the protein components of middle ear effusion (MEE) with human mast cells using acrylamide gradient gel electrophoresis and electrofocusing methods. This first direct comparison between the proteins of MEE and human mast cells has been made possible by a method developed in our laboratory for cultivation of human mast cells in tissue culture.On electrophoresis, we found that out of 12 bands of MEE proteins that were different from the serum, seven (58 per cent) had a similar electrophoretic migration rate (Rx) to mast cells. On electrofocusing, three of the four bands of MEE had a similar Rx to the mast cells. We have shown that proteins of mast cells and MEE had similar Rxs. Therefore, our study supports previous studies which suggests that mast cells play an important role in the aetiology of SOM.

Ear Effusion

Three studies will be reported in this paper and the suggestion made that there may be a connection between the findings. The first study concerns the middle ear status of 48 children treated in 1966/67 for middle ear effusion and followed up after ten years. Prior to treatment the median HL was 20 dB (SD = 13 dB) and at follow-up the median HL was 8 dB (SD = 5 dB). However, the otologic and tympanometric findings were less encouraging. Abnormal tympanic membranes (TM) were observed in almost half the children, the rate of abnormality relating to the number of surgical interventions made. However, the TM changes may be due either to the treatment or the disease itself. The second study concerns 104 children monitored by impedance testing over a ten-year period and tends to support the hypothesis that the effusion itself is the probable cause of the changes in the TM. The third study relates to applicants for hearing aids. Excluding those with clearly defined conditions such as otosclerosis, noise trauma and Meniére's disorder, etc, two clear groups emerged, one with uncontaminated sensorineural (SN) loss, the other with mainly SN loss but with a significant conductive overlay. Though the median hearing losses of the two groups are the same, the average age for the SN group (77; SD = 7 years) is 12 years greater than that of the “conductive” group (65; SD = 14 years). Few of the SN group can recall auditory dysfunction in childhood, but the majority of the conductive group have clear recall. It seems probable that middle ear disorders in childhood may give rise to auditory impairment in the elderly such that when combined with age-associated hearing loss the need for prosthetic aid arises at a much lower age.

Ear Effusion

Twenty-six children presenting bilateral secretory otitis media (SOM) had ventilating tubes inserted into both middle ears. Mucus was, however, aspirated only from one ear, the right side. The vast majority of ears right and left were seen to have cleared their effusion equally well regardless of whether they were aspirated on not. This experiment points toward the essential intactness of the mucociliary system and the patency of the lumen of the Eustachian tube in SOM. Promotion of middle ear clearance through ventilation, which reminds one of the second opening in a beer can, does obviously suggest the relief of some negative pressure. Direct manometric measurements of SOM middle pressure were performed in 41 ears showing negative pressure averaging —1.7 mm H2O, this range being two orders of magnitude less than tympanometric measurements. Normal ears did not have even such a small negative pressure. The validity of these direct manometric measurements was checked against a model of the middle ear. Tympanometry, which is a valid diagnostic tool, does indicate in all probability the presence of middle ear effusion due to its rheologic effects on the drum and ossicles rather than the measure of actual middle ear pressures. This is determined by the fact that direct needling of the middle ear, or even the insertion of a ventilating tube, did not change tympanometric values but aspiration of part of the effusion did: indeed the latter tended to bring manometry to normal values.
