Inner Ear Active Hearing Device in Non-Otosclerotic, Severe, Mixed Hearing Loss

OBJECTIVE: To verify the efficacy of a powerful active hearing device in a patient different from far-advanced otosclerosis, specifically when the stapes footplate is mobile. PATIENT: A patient with severe-to-profound mixed hearing loss, who was not benefiting from the use of a conventional hearing aid, was selected for an inner ear active implant. This was justified by a bone conductive threshold above 60 dB, which had discouraged any other rehabilitative solutions such as a bone conductive implant, or an active middle ear implant (AMEI). INTERVENTION: The hearing device was surgically applied using a combined transmastoid/transcanal approach. During surgery, a mobile stapes were found and was perforated for the insertion of a piston prosthesis, crimped on the new-incus of the device. MAIN OUTCOME MEASURE: The bone conduction threshold was assessed postoperatively to identify any possible surgery-related hearing deterioration. Pure tone audiometry was conducted in a sound field, and a speech reception threshold test was performed with the contralateral ear masked. The hearing outcome was assessed soon after the implant activation (6 weeks after surgery), and 6 months after surgery. RESULTS: Upon activation of the device, a PTA of 45 dB was obtained (at 0.5, 1, 2 and 4 kHz). At 6 months after surgery, the speech discrimination score reached 90% at 80 dB SPL. CONCLUSION: The application of the Codacs device has shown to be compatible with a mobile stapes footplate, as demonstrated in this report. The footplate perforation did not cause any further hearing deterioration, and has allowed to achieve a favorable auditory outcome

Transitions in auditory rehabilitation with bone conductive implant (bci)

Background: The bone conductive implants (BCI) are nowadays a reliable alternative for rehabilitation of specific forms of hearing loss, i.e. conductive, mixed or single sided deafness (SSD). Aims/Objective: To analyse the various factors in play when considering an auditory rehabilitation with a bone-conductive device (BCI). Materials and Methods: The clinical charts of subjects who underwent BCI application at the same Implanting Center from 2005 to 2018 were retrieved analysing also the reason for eventual explantation and the alternative option (transition) for hearing rehabilitation. Results: Nine BAHA Compact, 4 BAHA Intenso, 21 BAHA Divino, 3 BAHA BP100, 4 Ponto, 2 Sophono, 5 Bonebridge, 5 BAHA5 Attract; 11 BAHA5 Connect were used in 12 unilateral COM; 16 bilateral COM; 3 unilateral cholesteatoma; 6 bilateral cholesteatoma; 2 unilateral otosclerosis; 5 bilateral otosclerosis; 9 congenital malformations; 6 major otoneurosurgical procedures; 5 sudden deafness. Explantation was necessary for five subjects. Conclusions: Middle ear pathology and sequels from surgery represent the most common reason for BCI implantation, both in unilateral and in bilateral cases. Transition from one implantable device to another one can be predictable, mostly when explantation is necessary. Significance: The role of BCI for rehabilitation in middle ear pathology may be extremely important

Cone beam computed tomography after round window vibroplasty. do the radiological findings match the auditory outcome?

Conclusion: The CBCT imaging technique has proved to be reliable for assessing the appropriate positioning of the FMT in the round window niche. However, when considering specific imaging parameters, such as lack of bony contacts and appropriate inferior support, they would not seem essential for achieving a satisfactory functional outcome. Objectives: To evaluate the value of some imaging parameters derived from a Cone Beam Computed Tomography of the temporal bone for predicting a good functional outcome after Round Window Vibroplasty (RW-VP). Method: A CBCT imaging has been carried out at certain time after RW-VP surgery in a homogenous group of patients who presented with a mixed-type hearing loss after open tympanoplasty for a cholesteatoma. Three arbitrary radiological parameters have been considered for the purpose: the FMT/RW membrane contact; eventual FMT bony contacts; appropriatmess of inferior FMT support. The audiological assessment has taken into consideration the PTA4 (500-4000 Hertz), the PTA2 (125.250 Hertz), the WRS in quiet and in noise (SNR=+10). A comparison between the unaided and the RW-VP aided condition has been performed

Intralabyrinthine Vestibular Schwannoma Responsive to Intratympanic Gentamicin Treatment

Intralabyrinthine schwannoma (ILS) is a rare benign tumor that affects the ends of cochlear and vestibular nerves. In a majority of the cases, it occurs with unilateral progressive sensorineural hearing loss. Less frequent symptoms include tinnitus, imbalance, vertigo, or fullness. The advent of magnetic resonance imaging allows early diagnosis and enables an appropriate therapeutic protocol. This report describes a case of intravestibular schwannoma, with fluctuating hearing loss and intractable vertigo, treated with intratympanic gentamicin. The patient was a 28-year-old woman with intractable vertigo and fluctuating left-side hearing loss caused by left intravestibular schwannoma. Because surgery was temporarily rejected by the patient, a single dose of intratympanic gentamicin was administered. Following this, the patient showed a significant improvement in the symptoms. However, moderate to flat sensorineural hearing loss was also observed. Intratympanic gentamicin infiltration is a valid therapeutic option for patients with ILS, affected by intractable vertigo, when the patient refuses surgery

Intratympanic steroids as a salvage therapy for severe to profound idiopathic sudden sensorineural hearing loss

Background: Idiopathic sudden sensorineural hearing loss (ISSNHL) is defined as a decline in hearing affecting three or more frequencies by 30 dB Objective: The aim of this study was to evaluate the results of intratympanic steroids as a salvage treatment for severe ISSNHL. Materials and methods: A regimen of three IT steroid injections was offered to patients who failed a 7-days intravenous steroid treatment. Eighty-four patients underwent IT salvage treatment (IT group). Their outcomes were compared with those of 255 patients with severe ISSNHL who received the same intravenous steroid regimen without salvage IT steroid therapy (Control group). Results: 56% of the patients in the IT group had a hearing improvement of >15 dB after one month. The average hearing improvements were 26.5 ± 28 dB and 27.9 ± 24 dB in the IT group and the Control group, respectively (p ¼ .67). However, patients with a type E audiogram pattern (total deafness), displayed a substantial hearing gain. Conclusion: Intratympanic steroids failed to show a global auditory benefit as a salvage treatment in patients with severe ISSNHL. Significance: Our data suggest that a salvage treatment with intratympanic dexamethasone may be offered to patients with total deafness for whom the first systemic treatment has failed

The role of cochlear implantation in alleviating Tumarkin drop attacks of Meniere's disease; a case report

Ménière's disease (MD) patients may suffer episodes of sudden falls, named Tumarkin drop attacks (DAs). This fall occurs abruptly and without warning or loss of consciousness. DAs usually aggravate the clinical picture of MD and are challenging to manage. The present report describes a case treated by cochlear implantation (CI) due to concomitant deafness and offers some clinical considerations for this condition. A male patient aged 48 years with a 10-year history of definite bilateral MD had profound SNHL on the right and severe SNHL on the left side. He suffered from intermittent attacks of vertigo, ear fullness, and tinnitus and, in the last year, had developed DAs and experienced 14 episodes in the previous six months. The preoperative category of acoustic performance was 3. The Dizziness Handicap Inventory (DHI) questionnaire showed a total score of 46, which indicated a moderate degree of disability. A CI was planned for the right side. The patient did not report any further DAs episode for two years since then. The postoperative category of acoustic performance became 11, and the postoperative DHI questionnaire showed a decrease in the total score (from 46 to 19), which indicated a mild disability. Unilateral CI effectively alleviated the DAs associated with bilateral MD. Our report proposes a new modality for managing vertiginous symptoms in cases of MD with hearing loss without the need for more aggressive surgical interventions with the need for clinical trials to confirm our results

Delayed Effect of Active Pressure Treatment on Endolymphatic Hydrops

OBJECTIVE: To identify eventual correlations between the effect of low-pressure treatment and endolymphatic hydrops in Ménière patients. MATERIAL AND METHODS: The study group consisted of subjects affected by definite Ménière disease (2015) and a severe degree of disability, who received a ventilation tube with or without a low-pressure treatment before undergoing a surgical procedure (vestibular neurectomy). After the placement of the ventilation tube, the subjects were either left alone with the tube or received 1 month of self-administered low-pressure therapy with a portable device. In all subjects, an electrocochleography (ECochG) was performed and specific questionnaires - Dizziness Handicap Inventory (DHI) and Functional Scale Level (FSL) - were completed before starting either arm of treatment, at the end of treatment, and then 3 and 6 months later. RESULTS: All selected subjects presented with an ECochG pattern that was indicative of endolymphatic hydrops before starting either treatment. At the end of pressure treatment, 80% showed symptomatic improvement while maintaining the hydropic ECochG pattern. At the 3-month control stage, the hydropic pattern resulted normalized (<0.5) in all the improved subjects. CONCLUSIONS: Although 1 month of low-pressure treatment provided a positive symptomatological outcome, normalization of the hydropic ECochG parameters occurred only at a later time. Therefore, it is possible to assume that endolymphatic hydrops could be concurrent with a non-symptomatic stage of Ménière disease, and that the anti-hydropic effect of the low-pressure treatment, if any, would present with a certain delay after its completion

La presbiacusia. problematiche, diagnosi e opzioni riabilitative Presbycusis. problems, diagnosis and treatment

Presbycusis is sensorineural bilateral symmetrical, progressive hearing loss, caused by the advance of age. It involves mainly the higher frequencies and associated with tinnitus. Presbycusis the most frequent form of sensorineural hearing loss of the adult, characterized by the progressive difficulty following the conversation, especially in noisy environments. It is caused by reduction in the number of Corti cells, induced by genetic and environmental factors. In the elderly communication disorders generate isolation and depression, thereby causing a significant reduction of life quality. An observational study at our hospital in 2010, using questionnaires on verbal-acoustic communication (Self Assessment of Communication), found that older people have a poor perception of disability related to hearing loss. For presbycusis to be diagnosed, tone audiometry and speech and sovraliminary tests have to be carried out and must be integrated with the evaluation of extremely high frequencies (EHFs). In the majority of cases, rehabilitation involves conventional hearing aids. The most commonly used are retroauricular hearing aids, when these are contraindicated partially or totally implantable hearing device scan be used. Careful follow up of the patient is also fundamental, using benefit questionnaires to find the optimal fitting and therefore the best result

A case of cavernous hemangioma of the infratemporal fossa causing recurrent secretory otitis media

Secretory otitis media causes aural fullness and hearing loss secondary to Eustachian tube obstruction or incomplete resolution of acute otitis media. Every patient with unilateral middle ear effusion should undergo nasopharyngoscopy to assess the nasopharyngeal space. Expansive lesions at the level of pterygopalatine fossa may cause Eustachian tube compression with tube dysfunction with clinical findings of recurrent unilateral secretory otitis media. In this paper, a 55 years old man presented with a history of hearing loss and fullness in the left ear. Brain MRI scan showed the presence on the left side of a solid mass in the infratemporal masticatory space and the patient underwent endoscopic transnasal resection of the lesion. At 6 months follow-up there was no evidence of disease recurrency. In our opinion, it is important to add an imaging tool to the diagnostic algorithm in all those cases of secretory otitis media lasting more than 3 months that present a negative nasopharyngoscopy evaluation
