Recurrent Otitis Media

Extended high-frequency (EHF) hearing was studied in children with and without histories of chronic or recurrent otitis media (OM). The EHF thresholds were found to have good test-retest repeatability. Children with OM histories had poorer EHF hearing than children without OM histories. The EHF hearing in OM children appeared to be related to OM severity. Children with residual tympanometric abnormalities had poorer EHF hearing than OM children with normal middle ear function. The results suggest evidence for middle ear and inner ear components of EHF hearing losses in children with OM.

Air Conduction

A comparison has been made of air conduction threshold changes up to 1 year after myringotomy, aspiration of middle ear fluid, and insertion of ventilation tubes in ten patients with bilateral and 12 with unilateral secretory otitis media (SOM). Pure tone air conduction thresholds have been analyzed in three frequency groups: Low frequency (LF; 0.25, 0.5, and 1 kHz), high frequency (HF; 2,4, and 8 kHz), and extra-high frequency (EHF; 10, 12, 14, and 16 kHz). In the LF and HF ranges, significant improvement came during the first 24 hours after intubation, while in the EHF range, threshold lowering occurred gradually over the following 2 months. Possible explanations for these findings are discussed.

The Relationship

The Vanhuyse, Creten, and Van Camp (1975) model for analyzing high frequency tympanograms predicts the shapes of conductance, susceptance, and admittance tympanograms from the relationship between resistance and reactance tympanograms at the tympanic membrane. This model has been applied primarily to low impedance middle-ear pathologies but has not been applied extensively to the more commonly occurring high impedance pathologies. The purpose of this study was to extend the Vanhuyse et al. (1975) model to high impedance pathologies and to identify tympanometric parameters associated with otosclerosis, secretory otitis media, and lateral ossicular fixation. Data from previous experiments on the shape and absolute values of resistance and reactance tympanograms were used to calculate 678-Hz admittance tympanograms that were unique to each of the three high impedance pathologies. Guidelines for differentiating among the middle-ear pathologies on the basis of high frequency tympanometric shapes are presented.

Middle Ear Mucosa

The effect of platelet activating factor (PAF) was studied to elucidate its role in the pathogenesis of otitis media and sensorineural hearing loss. The PAF alone did not induce a reduction of ciliary activity of the cultured middle ear mucosa. However, a dose-dependent decrease in ciliary activity was observed in the presence of the medium containing both PAF and macrophages. Intravenous injection of PAF did not induce dysfunction of the mucociliary system or morphologic changes of epithelium in the tubotympanum, but cytoplasmic vacuolization and ballooning were observed in the inner ear within 1 hour after injection of PAF. In contrast, intratympanic injection of PAF induced mucociliary dysfunction and some pathologic changes in the tubotympanum. Intratympanic inoculation of PAF induced no pathologic findings in the inner ear. These results suggest that PAF is at least partially involved in the pathogenesis of certain middle ear diseases such as otitis media with effusion. Additionally, PAF might be involved in the pathogenesis of some types of unexplained sensorineural hearing loss.

Neuroendocrine adenoma of the middle ear (NAME) is a rare tumor. We report a case of NAME, the clinical and pathologic findings of which illustrate the biologic behavior of adenomatous tumors of the middle ear and their relationship with rare carcinoid tumors of the middle ear. A 29-year-old man presented with a history of recurrent otitis media, right conductive hearing loss, and aural fullness. The tumor was removed in its entirety. Otolaryngologists should be familiar with this unusual but important entity.

Recurrent Otitis Media

To investigate the possible association of chronic otitis media and school learning problems, past and current middle ear status in 53 learning-disabled (LD) children was compared to that of 56 control children without learning problems. A history of recurrent otitis media was obtained in 23% of the LD children and in 9% of the control children. Thirty-eight percent of LD children and 16% of control children had hearing abnormalities on pure tone audiometry; 49% of LD children and 21% of control children had abnormal tympanometry. LD children had significantly more middle ear malfunction than control children. Chronic, undetected middle ear problems may play a role in the etiology of some school learning disabilities.

Objective Language is almost always affected in fragile X syndrome (FXS), and a delay in language acquisition is one of the first characteristics. The aim of this work was to study the effect of recurrent middle ear infections on the language profile in boys with FXS. Study design: Prospective case series. Setting Academic Medical Center. Subjects and Methods The present study was conducted on 30 males, ranging in age from 4–10 years. They were diagnosed as having a full mutation of DNA. The males were divided into two groups: Group A included 15 children with a history of recurrent middle ear infections more than four times per year during the first 4 years of life, and Group B did not have a history of recurrent middle ear infections during the first 4 years of life. Language assessments were done for all participants using the Standardized Arabic Language test. Results Results showed significant delays in language development in children with FXS. Relative strengths in semantics compared to syntax and pragmatics were observed in all boys. The recurrent ear infections of the boys played an important role in the language development delay. The mean of receptive, expressive, and total language age was better and higher among boys without a history of recurrent middle ear infections compared to boys with recurrent middle ear infections. Conclusion Recurrent otitis media in boys with FXS exacerbates the language problems that exist in this syndrome.

Recurrent Otitis Media

One hundred young patients with recurrent otitis media with effusion (OME) were evaluated for IgE-mediated hypersensitivity by critical analysis of history, physical findings, skin testing for selected antigen, laboratory determination of total IgE, and radioallergosorbent testing (RAST) for six inhalant and two food allergens. The patients could be divided into allergic rhinitis and nonallergic groups. Allergic rhinitis patients had higher total IgE in their serum, and middle ear effusion (MEE). IgE was elevated in 16 of 35 allergic patients. in 8 of these 16 (23% of the allergic group), the IgE/mg protein was higher in the MEE than in the corresponding serum, suggesting local production of IgE. Nasal IgE was substantially increased in the allergic patients; however, in many patients there was no correlation between the corresponding MEE IgE and elevated nasal IgE, suggesting that local production of nasal and middle ear IgE is Independent. We conclude that IgE-mediated allergic reactions may play a role in the pathogenesis of OME in about 23% of young allergic patients.
