Use of hydrogen peroxide to clear blocked ventilation tubes.

Blocked tympanostomy tubes re-create the problem for which they were initially inserted. Hydrogen peroxide offers a noninvasive alternative to extracting the blocked tube and inserting a new tube. In this article we present the results of a long-term retrospective study of 95 patients (113 ears) who had occluded ventilation tubes following myringotomy. An 85% rate of success in opening the clogged tube with hydrogen peroxide is documented. The ototoxicity of the treatment is also examined. Ninety-nine percent of the patients showed no immediate change in bone conduction thresholds following the use of hydrogen peroxide. We have concluded that hydrogen peroxide is a convenient, noninvasive, and inexpensive treatment for blocked ventilation tubes.

Management of the hearing impaired child with serous otitis media.

The majority of research and informative papers dealing with otitis media with effusion (OME) are concerned with normally hearing children who display a mild conductive hearing loss associated with the infection. In contrast, the target of our manuscript is the child who has a previously documented sensori-neural hearing loss that is complicated by the onset of a middle ear infection. It is our clinical experience that OME in the hearing impaired child must be treated aggressively in order to adequately override the additional loss that accompanies a middle ear infection. A number of our patients are children who have various degrees of sensori-neural hearing loss. A significant number of these children also have experienced bouts of OME. The case studies presented will examine the effect that middle ear effusion has had on these hearing impaired children and discuss the importance of vigorous treatment of OME in hearing impaired children. Our intention is to alert the otologist and the audiologist to the possibility of OME in the hearing impaired child and to demonstrate the need for and the benefit of aggressive medical and/or surgical intervention.

Elevated bone conduction thresholds associated with middle ear fluid in adults.

Longitudinal observations of adult patients with documented cases of otitis media revealed fluctuations in bone conduction thresholds as well as air conduction thresholds. Previous investigations in this area presented conflicting information regarding temporary and permanent effects of serous otitis media on sensori-neural function. We conducted a detailed study, including complete otologic, audiologic, and tympanometric evaluation, of 30 adult patients exhibiting serous otitis media. Myringotomies were performed on all patients after appropriate medical management failed to clear the middle ear fluid and subsequent hearing loss. Pre- and postmyringotomy audiograms support our conclusion that middle ear fluid can produce artifactual shifts in bone conduction thresholds. Although the data presented was collected from a cohort of adults, the clinical implications are applicable to the pediatric population. We have observed a similar shift in bone conduction thresholds in children exhibiting serous otitis media, and we have observed improvement in the thresholds with removal of the fluid either by appropriate medical management or by myringotomy with fluid aspiration.

Myringotomy and tube ventilation in adults.

Otitis media is commonly diagnosed in children and is often successfully treated with myringotomy and tube insertion. It also occurs in adults but is frequently undetected and therefore untreated. Adults with hearing loss are often assumed to need a hearing aid, without consideration of a treatable problem. Physicians should be aware of otitis media in adults and the benefits of prompt medical or surgical intervention.

Sudden hearing loss.

This article describes a patient with documented sudden, severe, unilateral, sensorineural hearing loss occurring four days after audiometric evaluation for nonspecific complaints. He was hospitalized immediately; treatment included I.V. histamine and oral steroid therapy. He noted improvement within two days, and serial audiometry has documented recovery to the initial audiometric levels. We believe that this documentation of recovery to pre-illness levels is unique.
