Conductive Hearing

Introduction: Otosclerosis is a common form of conductive hearing loss characterized by abnormal bone remodeling exclusively in the otic capsule. The prevalence of otosclerosis varies in racial populations and is described as being rare in black African populations. In this paper we aim to report five cases of clinical, and surgically confirmed, otosclerosis in black individuals, in São Tomé and Príncipe.Material and Methods: Since February 2011, Ear, Nose and Throat consultations and surgeries specialty have been carried out at Dr. Ayres de Menezes Hospital in cooperation with the project ‘Health for all’. A retrospective analysis was undertaken of the records of all patients subjected either to stapedectomy or partial stapedectomy until February 2014. Information regarding clinical presentation, audiometric data and surgery reports was recorded.Results: Five adult patients underwent stapedectomy or partial stapedectomy. All of them presented with normal otoscopy, conductive or mixed hearing loss on audiogram and normal tympanometry with absent stapedial reflexes. None of the patients had signs of infection or history of head trauma. Three cases showed improvement in the air-bone gap after surgery. The other two were lost to follow-up.Discussion: We documented and surgically confirmed five cases of clinical otosclerosis in this population. A thematic review was carried out and concluded that, despite being described as a rare event in this race, available literature on this topic is not enough to state that there is lower prevalence of otosclerosis amongst the African population.Conclusion: Even if not common, otosclerosis cannot be disregarded as a possible cause for conductive hearing loss among the population of São Tomé and Principe.

<p class="abstract"><strong>Background:</strong> Chronic squamosal otitis media can occur due to many conditions affecting the middle ear. Most common sign of developing a chronic squamosal otitis media is formation of a retraction pocket in the tympanic membrane leading to further development of a cholesteatoma and if not treated properly, may lead to development of dangerous complication in the affected ear. These etiological factors may also affect the other ear. It is therefore very necessary to assess and diagnose the contralateral ear, so that the disease can be intervened and treated at the right time, to prevent any deterioration in hearing of the contralateral ear.</p><p class="abstract"><strong>Methods:</strong> The prospective study was done in 100 patients with unilateral chronic squamosal otitis media, where the contra lateral ear was examined and assessed for any hearing loss.  </p><p class="abstract"><strong>Results:</strong> We found hearing loss in the contra lateral ear ranging from mild conductive hearing loss to sensorineural hearing loss with the maximum patients with mild conductive hearing loss (42%) and lowest in sensorineural hearing loss (1%).  </p><p class="abstract"><strong>Conclusions:</strong> In our study, 76 patients were seen with conductive hearing loss. Out of that, 42% patients were seen with mild conductive hearing loss, 30% with moderate conductive hearing loss and 4% with severe conductive hearing loss. 20% patients were seen with normal hearing. 3% patients were seen with mixed hearing loss and only 1% patient was seen with sensorineural hearing loss in contralateral ear.</p>

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.

Inner Ear Disorders

This is a report of three cases of mixed hearing loss that resulted from inner ear disorders. Two cases were unilateral and the third was bilateral. The diagnosis was based on the findings of normal middle and external ears in association with the absence of round window reflexes. The contralateral stapedial reflex was present in the two unilateral cases. This is the first documentation of conductive deafness due to inner ear abnormality. This diagnosis should be considered in cases of conductive hearing loss if the middle and external ears are normal. More studies are needed to establish the pathophysiology of this entity.

Clinical experience with transcutaneous bone conduction implants has demonstrated that they are most beneficial for patients with purely conductive hearing loss in at least one ear. Percutaneous bone conduction implants, however, have been reported to provide adequate benefit for patients with mixed hearing loss with bone conduction pure-tone averages up to 45 db hl (Tjellstrom, 1989). The results of 24 Xomed Audiant osseointegrated bone conduction hearing devices (including a clinical trial on two patients using a new, larger magnet [Neodynium Iron Boron]), plus the results of eleven patients implanted and fitted with the percutaneous bone-anchored hearing aid are reported. Aided results with these devices will be presented. In addition, general comparisons of benefit obtained with the two devices will be made for patients who exhibit similar hearing losses. Finally, a direct comparison will be made on two patients who have undergone both implant procedures.

The article presents the materials of a retrospective analysis of the structure of diseases in the class of «ear and mastoid diseases» (according to the code ICD-10 H60-H95) in the adult population of the Samara region (SR) for the period from 2016 to 2019. The incidence and prevalence of chronic sensorineural hearing loss (SNHL) (code ICD-10 H90.3), mixed form of hearing loss (code ICD-10 H90.6) and conductive hearing loss (code ICD-10 H90.0) are considered. The dynamics of the adult population in the SR generally repeats the trend characteristic of the Volga Federal District in terms of an increase in the proportion of people over working age. Despite the natural decline in the region’s population in recent years, there has been an increase in the proportion of people over working age, which amounted to 10.,01%. The changes were reflected in the prevalence in the class of «ear and mastoid diseases»: in persons of the older age group, the indicator increased by 7,12%, in persons of working age by 0,61%. In the adult population of the region, there is an increase in cases of hearing loss of a mixed and sound-perceiving character, with consistently low rates of conductive hearing loss. In both groups of the adult population of the Samara region in 2016–2019, an increase in the cases of SNHL and hearing loss of a mixed nature was revealed. Moreover, in persons older than working age, the number of SNHL cases during the analyzed period was on average 2,32 times higher, and the number of mixed hearing loss cases was 2.2 times higher. The data of the study must be taken into account for planning the timely detection and examination of adults with hearing loss when they turn to an otorhinolaryngologist-audiologist, as well as to general practitioners and geriatricians, which will maximize their ability to work and social activity.

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.

AbstractIntroduction:This paper reviews our experience of ossicular chain injuries following head trauma treated at Groote Schuur Hospital, Cape Town, South Africa.Materials and methods:We performed a retrospective chart review of all patients with a history of head trauma and a conductive hearing loss who had undergone exploratory tympanotomy. Sixteen patients were included in the study.Results:Injury was most common at the incudostapedial joint (63 per cent). Disarticulations of the icudostapedial joint were treated with cartilage interposition in all cases. Audiography showed an improvement in 12 of the patients, with an average improvement of 35 dB.Discussion:We discuss the various options available to the otologist to repair ossicular disruptions after trauma. In this series, cartilage autografts were used in most incudostapedial joint injuries, with excellent closure of the air–bone gap.Conclusion:Cartilage interposition was a very successful method of repairing incudostapedial joint dislocation in this series, at short term follow up.

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.
