The purpose of the study was to investigate the relative contributions of age, gender, ethnic background, and a history of middle ear disease on the amount of conductive hearing impairment among native and non-native audiology patients in the Canadian North. A second goal of the study was to determine risk factors for conductive hearing loss in the patients studied. Three ethnic groups were represented among the 3,094 patients: Inuit, American Indian, and non-native. Loglinear and logit statistical models were applied, and these data were best explained by a 3-way interaction of history of middle ear disease, ethnic group, and hearing loss, and the 2-way interaction of age and hearing loss. The Inuit appear to be at higher risk for conductive hearing impairment than the other ethnic groups. Conductive hearing loss also appears to increase as age increases through the teenage years for all the patients regardless of ethnic group membership. Preschoolers were at the lowest risk for conductive hearing loss. The trend for the amount of hearing impairment to increase throughout childhood suggests that children living in the Arctic may manifest a unique and more serious form of the disease not often observed in audiology patients who are Caucasian in southern Canada or the United States or that they may be exposed to additional risk factors.

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.

AbstractObjectiveThis case report presents a middle-ear osteoma mimicking otosclerosis that was located at the promontory. The osteoma was successfully excised using an endoscopic transcanal approach without any complication.Case reportA 21-year-old man presented with a 4-year history of progressive conductive hearing loss (47 dB with a 30-dB air–bone gap) with intermittent tinnitus of recent onset in his right ear. Endoscopic transcanal middle-ear exploration showed that an osteoma located on the promontory was restricting the mobility of the stapes by affecting the anterior crus of the stapes. After transcanal resection of the osteoma, pure tone audiometry improved to 23 dB with a 5-dB air–bone gap. Tinnitus resolved spontaneously without any additional treatment.ConclusionPromontory osteomas, a rare and usually asymptomatic clinical entity, should be taken into consideration in the differential diagnosis in patients with progressive conductive hearing loss and tinnitus with intact stapedial reflexes and normal otoscopic findings.

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.

Up to 3 million people in Britain might be helped by hearing aids.1 2 Most are over 65 years of age, but some are infants. All should be referred to specialist centres for assessment as soon as possible. Hearing aids generally help most in disorders of the middle ear (conductive hearing loss); they can also help those with sensorineural and other forms of hearing loss. The use of an aid often needs to be supplemented by lip reading and other means of auditory training.1 3

The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

We recorded auditory-evoked magnetic responses with a whole-scalp 122-channel neuromagnetometer from seven adult patients with unilateral conductive hearing loss before and after middle ear surgery. The stimuli were 50-msec 1-kHz tone bursts, delivered to the healthy, nonoperated ear at interstimulus intervals of 1, 2, and 4 seconds. The mean preoperative pure-tone average in the affected ear was 57 dB hearing level; the mean postoperative pure-tone average was 17 dB. The 100-msec auditory-evoked response originating in the auditory cortex peaked, on average, 7 msecs earlier after than before surgery over the hemisphere contralateral to the stimulated ear and 2 msecs earlier over the ipsilateral hemisphere. The contralateral response strengths increased by 5% after surgery; ipsilateral strengths increased by 11%. The variation of the response latency and amplitude in the patients who underwent surgery was similar to that of seven control subjects. The postoperative source locations did not differ noticeably from preoperative ones. These findings suggest that temporary unilateral conductive hearing loss in adult patients modifies the function of the auditory neural pathway. (Otolaryngol Head Neck Surg 1998;119:125-30.)

Isolated cases of spontaneous cerebrospinal fluid (CSF) leakage with and without middle ear encephalocele have been reported. These leaks are usually accompanied by episodes of recurrent meningitis, hearing loss, or chronic headache. In this article, we report seven new cases of spontaneous CSF leakage. Six of these patients had conductive hearing loss and serous otitis media, and three had recurrent meningitis. Prior to a definitive diagnosis, six patients had received myringotomy tubes, which produced profuse clear otorrhea. Three patients had positive beta-2 transferrin assays. Computed tomography and magnetic resonance imaging confirmed a defect in the temporal bone tegmen. A combined transmastoid and middle fossa surgical approach with a three-layer closure was used to repair the tegmen defect. All patients had a lumbar drain placed prior to surgery. In addition to describing the seven new cases, we review the history of CSF leakage and discuss diagnostic methods, surgical findings, and our recommendations for management.

Objectives: The objective of this study was to begin to measure the prevalence of elevated hearing thresholds in Ethiopia, with audiometric equipment, including bone oscillators and tympanometers. To that end Ethiopian nationals were trained in audiometric techniques to obtain sensorineural hearing loss (SNHL) and conductive hearing loss (CHL) rates in school age children. Methods: Five mainstreamed public grade schools in northern Ethiopia were the sites for audiometry campaigns examining 1351 children and testing them with behavioral audiometry. Results: Seven percent of students had SNHL > 20 dB in at least 1 frequency in at least 1 ear, and 0.6% of ears had SNHL > 50 dB. Eighteen percent8% of students had CHL > 20 dB in 1 or both ears. The frequency with the highest incidence of elevated pure tone thresholds was at 8000 Hz. Seven percent of students had an air bone gap at 2000 and/or 4000 Hz of at least 15 dB. Air bone gap is not obtained at 8000 Hz. There were 22 perforated tympanic membranes in 17 children (0.8% of tympanic membranes, 1% of students). Conclusion: This study gives a baseline for the prevalence of hearing loss in school age children in mainstreamed northern Ethiopian schools. It is the first of its kind and perhaps can help in estimated hearing health needs there. Level of Evidence: 2

Introduction. Despite modern radiological workup, surgeons can still be surprised by intraoperative findings or by the pathologist’s report.Materials & Methods. We describe the case of a 52-year-old male who was referred to our clinic with a single sided conductive hearing loss. He ultimately underwent middle ear exploration and excision of a middle ear tumour followed by second look and ossiculoplasty a year later.Results. Though preoperative CT and MRI scanning were suggestive of a congenital cholesteatoma, the pathologist’s report diagnosed a middle ear adenoma.Discussion. Middle ear glandular tumors are extremely rare and, despite numerous histological techniques, continue to defy satisfactory classification. Most surgeons advocate surgical excision though evidence of the tumour’s natural course and risk of recurrence is lacking.
