Ceruminous glands are located in the skin of the cartilaginous portion of the external auditory canal, and ceruminous gland adenoma originating from the middle ear mucosa is extremely rare. We report a case of middle ear ceruminous gland adenoma which caused long-standing otomastoiditis and mixed hearing loss with a large air-bone gap by obstructing the bony Eustachian tube. We discuss the clinical characteristics and histologic features of the present case.

ABSTRACT A 32-year-old female presented with a history of otorrhea and hearing loss in her right ear since 2 years. On examination, external auditory canal was found to be filled with polypoidal tissue along with mucopurulent discharge. Audiometry showed mixed hearing loss of 50, 55, and 60 dB with air-bone gap of 30, 35, and 40 dB at frequencies of 0.5, 1, and 2 kHz respectively. She was operated for the same, and biopsy was sent for histopathological examination, which showed granulomatous inflammation. The patient was treated with antituberculous therapy, and she responded fully to the treatment. How to cite this article Gulati A, Kakkar V, Sharma C, Pareek M, Bishnoi S. Tuberculosis of Middle Ear.

Introduction: Epidermolysis bullosa (EB) is a spectrum of mechanobullous disorders characterized by blistering following minor trauma or traction to the skin. Hearing loss in this population is poorly described in the otolaryngology literature, and its treatment oftentimes results in external auditory canal skin irritation. Case Presentation: We present the case of a 26-year-old female with EB and mixed hearing loss unable to wear conventional hearing aids due to sequelae of the external auditory canals. An osseointegrated implant was used as other hearing aids were deemed to be too destructive of the external auditory canal skin. Management and Outcome: Our patient underwent placement of a right bone-anchored hearing aid with minimal disruption of the surrounding skin using a minimally invasive punch technique. Over 1 year of follow-up, her course was complicated by 1 simple cellulitic infection at the surgical site treated successfully with oral antibiotics. Discussion: The literature regarding the otolaryngologic manifestations of EB is sparse. The otologic sequelae are particularly overlooked in the workup and management. Based on the results of this case study, it appears that an osseointegrated implant can be safely utilized to treat significant mixed or conductive hearing loss in patients with EB.

<p>Foreign body in ear is an emergency encountered by an otolaryngologist and if not removed it can lead to serious complications. Most commonly foreign body in ear is lodged in external auditory canal while it’s rare to find it in middle ear. We report a case of foreign body in the middle ear in a 3-year-old child who presented to us with chronic discharging ear who was then suspected to be unsafe ear and so was taken up for exploration under microscope. A pink polypoidal mass arising from middle ear mucosa was found and following its removal- to our surprise; a blackish rubbery debris filling the middle ear cavity and attic area along with embedded foreign body was extracted. We conclude that pediatric patients with chronic ear discharge not responding to antibiotics should raise a suspicion of FB in the middle ear and explored timely.</p>

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.

Background: The conventional therapy for severe mixed hearing loss is middle ear surgery combined with a power hearing aid. However, a substantial group of patients with severe mixed hearing loss cannot be treated adequately with today’s state-of-the-art (SOTA) power hearing aids, as predicted by the accompanying part I of this publication, where we compared the available maximum power output (MPO) and gain from technical specifications to requirements for optimum benefit using a common fitting rule. Here, we intended to validate the theoretical assumptions from part I experimentally in a mixed hearing loss cohort fitted with SOTA power hearing aids. Additionally, we compared the results with an implantable hearing device that circumvents the impaired middle ear, directly stimulating the cochlea, as this might be a better option. Objectives: Speech recognition outcomes obtained from patients with severe mixed hearing loss supplied acutely with a SOTA hearing aid were studied to validate the outcome predictions as described in part I. Further, the results obtained with hearing aids were compared to those in direct acoustic cochlear implant (DACI) users. Materials and Methods: Twenty patients (37 ears with mixed hearing loss) were provided and fitted with a SOTA power hearing aid. Before and after an acclimatization period of at least 4 weeks, word recognition scores (WRS) in quiet and in noise were studied, as well as the speech reception threshold in noise (SRT). The outcomes were compared retrospectively to a second group of 45 patients (47 ears) using the DACI device. Based on the severity of the mixed hearing loss and the available gain and MPO of the SOTA hearing aid, the hearing aid and DACI users were subdivided into groups with prediction of sufficient, partially insufficient, or very insufficient hearing aid performance. Results: The patients with predicted adequate SOTA hearing aid performance indeed showed the best WRS in quiet and in noise when compared to patients with predicted inferior outcomes. Insufficient hearing aid performance at one or more frequencies led to a gradual decrease in hearing aid benefit, validating the criteria used here and in the accompanying paper. All DACI patients showed outcomes at the same level as the adequate hearing aid performance group, being significantly better than those of the groups with inadequate hearing aid performance. Whereas WRS in quiet and noise were sensitive to insufficient gain or output, showing significant differences between the SOTA hearing aid and DACI groups, the SRT in noise was less sensitive. Conclusions: Limitations of outcomes in mixed hearing loss individuals due to insufficient hearing aid performance can be accurately predicted by applying a commonly used fitting rule and the 35-dB dynamic range rule on the hearing aid specifications. Evidently, when outcomes in patients with mixed hearing loss using the most powerful hearing aids are insufficient, bypassing the middle ear with a powerful active middle ear implant or direct acoustic implant can be a promising alternative treatment.

Ige Mediated

A pathophysiologic model of otitis media with effusion secondary to IgE-mediated hypersensitivity is described. Specific mediators of inflammation are released by mucosal mast cells in the nasal mucosa following the interaction of antigen and specific IgE antibody. These mediators increase vascular permeability, mucosal blood flow, and, most important, mucus production. Furthermore, accessory cell types are recruited by colony-stimulating factors that in turn provide an autocrine-positive feedback for the influx of further inflammatory cells. The eustachian tube is then effectively obstructed by both intrinsic venous engorgement and extrinsic mucus plugs, isolating the middle ear space from the ambient environment The net result is the increased exchange of nitrogen into the middle ear mucosa from the middle ear cavity. This causes the development of a significant middle ear underpressure that disrupts tight junctions and allows for transudation of fluids into the middle ear space. The prolonged obstruction of the eustachian tube with mucus results in middle ear inflammation, mucosal metaplasia, and increased glandular activities, all of which are hallmarks of chronic otitis media with effusion.

Conductive Hearing

Cholesteatomas are found almost exclusively in the middle ear and mastoid. Occasionally this disease is seen in the external auditory canal. Cholesteatoma of the external auditory canal is a rare condition. Severe pain and profuse discharge associated with a normal eardrum and normal hearing are essential clinical features. In addition, we found facial paresis and conductive hearing loss in our case. Smaller cholesteatomas can be managed by frequent debridement in the office; larger lesions require surgical intervention. Surgery is successful in resolving otorrhea and relieving pain. In addition, our own experience has shown that surgery is successful in relieving facial paresis.

Bone Conduction Implant

Background: the Bonebridge hearing implant is an active transcutaneous bone conduction implant suitable for various types of hearing loss. It was first launched in 2012 as the BCI 601, with a newer internal part (BCI 602) released in 2019. With the new size and shape, the BCI 602 can be used in patients previously excluded due to insufficient anatomical conditions, especially in patients with congenital defects of the outer and middle ear. Objectives: the purpose of this study is to evaluate the objective and subjective benefits of the new Bonebridge BCI 602 in children who have hearing impairment due to conductive or mixed hearing loss. Safety and effectiveness of the device was assessed. Methods: the study group included 22 children aged 8–18 years (mean age 14.7 years) who had either conductive or mixed hearing loss. All patients were implanted unilaterally with the new Bonebridge BCI 602 implant. Pure tone audiometry, speech recognition tests (in quiet and noise), and free-field audiometry were performed before and after implantation. Word recognition scores were evaluated using the Demenko and Pruszewicz Polish Monosyllabic Word Test, and speech reception thresholds in noise were assessed using the Polish Sentence Matrix Test. The subjective assessment of benefits was carried outusing the APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire. Results: after implantation of the Bonebridge BCI 602 all patients showed a statistically significant improvement in hearing and speech understanding. The mean word recognition score (WRS) changed from 12.1% before implantation to 87.3% after 6 months. Mean speech reception threshold (SRT) before implantation was +4.79 dB SNR and improved to −1.29 dB SNR after 6 months. All patients showed stable postoperative results. The APHAB questionnaire showed that difficulties in hearing decreased after implantation, with a statistically significant improvement in global score. Pre-operative scores (M = 35.7) were significantly worse than post-operative scores at 6 months (M = 25.7). Conclusions: the present study confirms that the Bonebridge BCI 602 is an innovative and effective solution, especially for patients with conductive and mixed hearing loss due to anatomical ear defects. The Bonebridge BCI 602 system provides valuable and stable audiological and surgical benefits. Subjective assessment also confirms the effectiveness of the BCI 602. The BCI 602 offers the same amplification as the BCI601, but with a smaller size. The smaller dimensions make it an effective treatment option for a wider group of patients, especially children with congenital defects of the outer and middle ear.
