Ear Effusion

Acute suppurative otitis media (AOM) is a common, painful condition affecting 20% of children under 4 years at least once a year,1 and perhaps more in infancy when clinical examination is most difficult. Infectious complications such as mastoiditis, meningitis and cerebral abscess are now rare, but chronic middle ear effusion and hearing loss remain common. Hearing loss may persist long after the infective episode,2 and may impair learning.

Ear Effusion

We conducted a randomized, controlled clinical trial to investigate the efficacy of treatment of persistent middle ear effusion (MEE) and associated hearing loss with a modified Politzer device used in the home setting over a 7-week period. Efficacy was determined by comparing pre-and post therapy air-conduction thresholds, tympanometric peak pressures, and otoscopic findings. The study group was made up of 94 children (174 ears), aged 4 to 11 years, who had at least a 2-month history of MEE and associated hearing loss. At study's end, patients in the treatment group experienced statistically significant improvements in all measured outcomes; no significant improvements were seen in the control group in all measured outcomes. At study's end, the hearing sensitivity of 73.9% of the treated ears was within normal limits, compared with only 26.7% of the control ears. These findings demonstrate that home treatment of children with persistent MEE and associated hearing loss with the modified Politzer device is highly efficacious.

Impedance Bridge

STATEMENT OF PROBLEM There is confusion in schools about the proper use of the impedance bridge. Some groups recommend its use as a substitute for audiometry and suggest physician referral on the basis of an abnormal tympanogram. In our opinion this is inappropriate. BACKGROUND The impedance bridge primarily detects asymptomatic middle ear effusion. This effusion may cause a conductive hearing loss (rarely greater than 20 to 30 dB). There is no consensus as to the advisability of treating this effusion, because it usually remits spontaneously within 2 to 3 months. RECOMMENDATIONS The Committee on School Health recommends that (1) the impedance bridge should not be used in mass screening programs for the detection of hearing loss or middle ear effusion; (2) the impedance bridge may be used in the school setting only as an aid in the diagnosis of individual children who are at high risk for, or who are suspected of having, otitis media with effusion; (3) hearing screening by pure-tone audiometry be used as the primary method of detection of hearing loss in school children; (4) the impedance bridge not be used as a replacement for audiometric screening, because it will not detect sensory neural hearing loss and may lead to overreferral of children with asymptomatic middle ear effusion; (5) any persistent abnormality detected by either the impedance bridge or pure-tone audiometry should result in a prompt referral to the child's pediatrician.

Hearing was tested in 18 patients with Pierre Robin syndrome (PRS). These results were compared with those obtained for 243 patients with either cleft lip or cleft palate, or both. None of the PRS group patients had middle ear or inner ear malformations, or sensorineural hearing loss in speech frequencies. Hearing loss in PRS is usually conductive, bilateral, and more frequent in PRS patients (30 ears or 83.33%) than in patients who do not have PRS (290 ears or 59.67%). A significantly higher (p < .01) mean of hearing loss for air conduction in speech frequencies (MHLSF = 24.5 dB) was found in PRS patients than in patients without PRS (MHLSF = 17.8 dB). The ears of the PRS patients with hearing loss were examined, revealing middle ear effusion. In all cases, hearing was restored to a normal level through suction and the use of ventilation tubes.

Oscillating Sphere

Both dynamic viscosity (n′) and elasticity (G′) of middle ear effusion were measured with an oscillating sphere magnetic rheometer and compared with the degree of conductive hearing loss in 65 ears of 40 children. There was a significant correlation between n′ and the magnitude of the air-bone gap at 500 and 1,000 Hz, but there was no significant correlation between G′ and the magnitude of the air-bone gap at 2,000 or 4,000 Hz. No significant correlation was noted between G′ and the magnitude of the air-bone gap at 500,1,000, 2,000, or 4,000 Hz. These results indicate that the n′ of middle ear effusion has an effect on the amount of hearing impairment at frequencies below 1,000 Hz.

Background: Delivery of therapeutic agents directly through the round window (RW) offers promise for treating sensorineural hearing loss. However, hearing loss can result from the surgical approach itself, and the reasons for this are poorly understood. We examined the hearing loss following the 3 major steps involved with the RW approach to access the mouse cochlea: bullostomy, RW puncture, and RW injection. Methods: Twenty-one adult CBA/J mice underwent bullostomy alone, 10 underwent RW puncture, and 8 underwent RW injection with PBS with 5% glycerol. Auditory brainstem responses (ABR) and otoscopy were performed preoperatively and up to 6 weeks postoperatively. Hair cells were stained, and survival was assessed using immunofluorescence. Results: One week postoperatively, mice in all groups showed significant threshold shifts. Otoscopy revealed approximately half of all mice had middle ear effusion (MEE), with a higher incidence of effusion in the RW puncture and RW injection groups. Those with MEE had significant ABR threshold shifts, whereas those without MEE had minimal hearing loss. MEE persisted through 6 weeks in a majority of cases, but in those mice with MEE resolution, there was at least partial improvement in hearing. Immunohistochemistry showed minimal loss of hair cells in all animals. Conclusion: MEE is highly correlated with hearing loss in mice undergoing RW surgery. Otoscopy is an important adjunct to consider after ear surgery in mice, as MEE may contribute to postsurgical hearing loss.

The purpose of this paper is not to propose that auditory brainstem response (ABR) be utilized for the assessment of conductive losses, but to define the effects of conductive hearing loss on the ABR when such a complication occurs. Conductive losses attenuate cochlear stimulation. Since wave V latency is inversely related to stimulus intensity, the magnitude of the conductive loss should be a predictor of the wave V latency delay. In this study, ABR wave V latencies from patients with known conductive losses due to canal occlusion, middle ear effusion, ossicular fixation and chain interruption were compared with latency values calculated from the magnitude of the loss. In those patients with occlusion of the external auditory canal and middle ear effusion, the shift of the wave V latency-intensity function correlated well with the air-bone gap. This correlation was poor for patients with ossicular chain disorders. In mixed hearing losses, the increased wave V latency due to the conductive component may totally mask an increase in latency caused by a retrocochlear component.
