    ABSTRACT: Surgical management of cholesteatoma limited to the attic and/or mesotympanum remains controversial. The aim of this study is to evaluate the anatomical and the functional results of trans-canal atticotomy in this pathological condition. The records of 27 adult patients treated from 2008 to 2014 who underwent trans-canal atticotomy for primary cholesteatoma surgery were reviewed. Pre-operative physical examination, audiometry, and CT-scan have been analyzed. Intraoperative findings have been described as well as the surgical technique. Anatomical and functional results have been evaluated with a mean follow-up of 24 ± 12.2 months, and the results of a CT-scan performed 1 year after surgery were examined to assess the presence of residual disease. Surgeries were uneventful. During the follow-up, 1 patient (4 %) experienced a retraction of the attical reconstruction; all the other patients had a well-healed tympanic drum with stable attical reconstruction. The mean air-bone gap was 19 ± 12.2 and 10 ± 7.3 dB pre-operatively and post-operatively, respectively (mean ± SD, p = 0.001, paired t test). Twenty-two patients (81 %) had no opacity suggesting residual cholesteatoma in CT-scan. Four patients (15 %) presenting an opacity at CT-scan underwent MRI study that was negative for residual cholesteatoma. One patient (4 %) had displacement of the ossicular prosthesis. In conclusion, cholesteatomas restricted to the attic and/or mesotympanum can be removed in a one-stage technique with no visible residual at 1 year, and with closure of the air-bone gap by 50 %.

    ABSTRACT: Facial nerve schwannoma is the most common facial nerve tumor, but its therapeutic strategy remains debated. The aim of this study is to analyze the facial nerve function and the hearing outcomes after surgery or wait-and-scan policy in a facial nerve schwannoma series. A monocentric retrospective review of medical charts of patients followed for an intratemporal facial nerve schwannoma between 1988 and 2013 was performed. Twenty-two patients were included. Data were extracted pertaining to the following variables: patient demographics, tumor localization, clinical and imaging features, facial nerve function and hearing levels, and details of surgical intervention. The majority of tumors were located at the geniculate ganglion. Initial symptoms were mainly facial palsy and hearing loss. The average follow-up was 4.8 ± 4.5 years. Nineteen patients underwent surgery, and three patients were observed. After surgery, 11 patients had a stable or improved facial nerve function (57.9 %), and 8 patients had a worsened facial nerve function (42.1 %). Facial nerve function was in the majority of cases a HB grade III, depending on surgical strategy. No patient presented a postoperative HB grade V or VI. Regarding the hearing, it remained stable after surgery in 52.6 % of cases, and improved in 10.5 % of cases. Among monitored patients, facial nerve function and hearing remained stable. Surgery for facial nerve schwannoma is a safe and effective option in the treatment of these tumors.

    ABSTRACT: Objective . To evaluate the cutaneous and the inner ear tolerance of bioactive glass S53P4 when used in the mastoid and epitympanic obliteration for chronic otitis surgery. Material and Methods . Forty-one cases have been included in this prospective study. Cutaneous tolerance was clinically evaluated 1 week, 1 month, and 3 months after surgery with a physical examination of the retroauricular and external auditory canal (EAC) skin and the presence of otalgia; the inner ear tolerance was assessed by bone-conduction hearing threshold 1 day after surgery and by the presence of vertigo or imbalance. Results . All surgeries but 1 were uneventful: all patients maintained the preoperative bone-conduction hearing threshold except for one case in which the round window membrane was opened during the dissection of the cholesteatoma in the hypotympanum and this led to a dead ear. No dizziness or vertigo was reported. Three months after surgery, healing was achieved in all cases with a healthy painless skin. No cases of revision surgery for removal of the granules occurred in this study. Conclusion . The bioactive glass S53P4 is a well-tolerated biomaterial for primary or revision chronic otitis surgery, as shown by the local skin reaction which lasted less than 3 months and by the absence of labyrinthine complications.

    ABSTRACT: The aim of this study was to assess the mental representation of the insertion axis of surgeons with different degrees of experience, and reproducibility of the insertion axis in repeated measures. A mastoidectomy and a posterior tympanotomy were prepared in five different artificial temporal bones. A cone-beam CT was performed for each temporal bone and the data were registered on a magnetic navigation system. In these five temporal bones, 16 surgeons (3 experts; >50 cochlear implant surgery/year; 7 fellows with few cochlear implant experience, and 6 residents) were asked to determine the optimal insertion axis according to their mental representation. Compared to a planned ideal axis, the insertion axis was better determined by the experts with higher accuracy (axial: 7° ± 1.5°, coronal: 6° ± 1.5°) than fellows (axial: 14° ± 1.7°, coronal: 13° ± 1.7°; p < 0.05), or residents (axial: 15° ± 1.5°; p < 0.001, coronal: 17° ± 1.9°; p < 0.001). This study suggests that mental representation of the cochlea is experience-dependent. A high variation of the insertion axis to the scala tympani can be observed due to the complexity of the temporal bone anatomy and lack of landmarks to determine scala tympani orientation. Navigation systems can be used to evaluate and improve mental representation of the insertion axis to the scala tympani for cochlear implant surgery.

    ABSTRACT: Otosclerosis is a complex disease of the human otic capsule with highest incidence in adult Caucasians. So far, many possible etiological factors like genetics, HLA, autoimmunity, viruses, inflammation, and hormones have been investigated but still the development of the disease remains unclear. Currently, the surgical replacement of stapes (stapedotomy) remains the best possible treatment option. In this review, we analyze different etiological factors studied so far in otosclerosis pathophysiology and discuss most recent findings and possible new research pathways.

    ABSTRACT: Inner ear diseases are not adequately treated by systemic drug administration mainly because of the blood-perilymph barrier that reduces exchanges between plasma and inner ear fluids. Local drug delivery methods including intratympanic and intracochlear administrations are currently developed to treat inner ear disorders more efficiently. Intratympanic administration is minimally invasive but relies on diffusion through middle ear barriers for drug entry into the cochlea, whereas intracochlear administration offers direct access to the colchlea but is rather invasive. A wide range of drug delivery systems or devices were evaluated in research and clinic over the last decade for inner ear applications. In this review, different strategies including medical devices, hydrogels and nanoparticulate systems for intratympanic administration, and cochlear implant coating or advanced medical devices for intracoclear administration were explored with special attention to in vivo studies. This review highlights the promising systems for future clinical applications as well as the current hurdles that remain to be overcome for efficient inner ear therapy. Copyright © 2015.

    ABSTRACT: The aim of this study was to compare a contralateral routing of signal (CROS) hearing aid to a transcutaneous bone-anchored device in the same conditions. This prospective crossover study included 18 adult patients with a single-sided deafness (SSD). After a trial period of 60 days with CROS and 7 days with a transcutaneous bone-anchored device (Alpha 1®, Sophono, Boulder, Colo., USA) on a headband, 13 (72%) patients opted for Alpha 1, 2 patients for CROS, and 3 rejected both rehabilitation methods. Clinical tolerance, satisfaction, hearing performances (pure-tone audiometry, speech test in quiet and in noise, stereo audiometry, sound localization, and Hearing in Noise Test), and quality of life (Glasgow Benefit Inventory, Abbreviated Profile of Hearing Aid Benefit and Glasgow Hearing Aid Benefit questionnaires) were measured at 3 and 12 months after the implantation. Both devices improved equally the hearing in noise and the quality of life. Transcutaneous devices represent an effective option in SSD. © 2015 S. Karger AG, Basel.

    ABSTRACT: The aim of this work was to thoroughly study the effect of liposomes on the rheological and the syringeability properties of hyaluronic acid (HA) hydrogels intended for the local administration of drugs by injection. Whatever the characteristics of the liposomes added (neutral, positively or negatively charged, with a corona of polyethylene glycol chains, size), the viscosity and the elasticity of HA gels increased in a lipid concentration-dependent manner. Indeed, liposomes strengthened the network formed by HA chains due to their interactions with this polymer. The nature and the resulting effects of these interactions depended on liposome composition and concentration. The highest viscosity and elasticity were observed with liposomes covered by polyethylene glycol chains while neutral liposomes displayed the lowest effect. Despite their high viscosity at rest, all the formulations remained easily injectable through needles commonly used for local injections thanks to the shear-thinning behavior of HA gels. The present study demonstrates that rheological and syringeability tests are both necessary to elucidate the behavior of such systems during and post injection. In conclusion, HA liposomal gels appear to be a promising and versatile formulation platform for a wide range of applications in local drug delivery when an injection is required. Copyright © 2015.

    ABSTRACT: Aim of the Study: To review indications, anatomical results, and complications of cochlear implant (CI) surgery in adults for which middle ear and mastoid obliterations were performed. Patients and Methods: Thirty cases (26 patients, 4 bilaterally implanted) of 837 CI surgeries (3.5%) performed between January 2009 and December 2013 have been included in this retrospective study. The mean follow-up was 21 +/- 18 months (mean +/- SD, range 3-58). There were 11 males and 15 females. The mean age was 59 +/- 19 years (range 35-82). All surgeries were performed with a single-stage technique including a canal wall down mastoidectomy with external auditory canal closure and mastoid obliteration with fat. A postoperative CT scan was performed in all cases. Results: Etiologies of hearing loss were mainly chronic otitis with or without cholesteatoma in 24 cases. Other etiologies were meningitis with cochlear ossification in one case, progressive hearing loss in two cases, enlarged vestibular aqueduct in one case, temporal bone fracture with CSF leak in one case, and congenital aural atresia in one case. Four of those 30 cases were revision CI surgery for electrode array misplacement (one case with cochlear ossification) or extrusion from an open cavity (one case) and recurrent cholesteatomas (two cases). All surgeries were uneventful and performed in a single stage. The electrode array was inserted in the basal turn (29 cases) or in the middle turn (one case) of the cochlea. No complications were observed. Two cases of postoperative abdominal hematoma were drained under local anesthesia. A major failure of the CI device occurred 5 months after surgery. Conclusion: CI with mastoid and middle ear obliteration is a safe and effective technique for selected cases of cochlear implantation. Mastoid obliteration prevents from recurrent disease and lowering the facial ridge allows more space to manage extensive cochlear ossification or malformation.

    ABSTRACT: Menière's disease, clinically characterized by fluctuating, recurrent, and invalidating vertigo, hearing loss, and tinnitus, is linked to an increase in endolymph volume, the so-called endolymphatic hydrops. Since dysregulation of water transport could account for the generation of this hydrops, we investigated the role of aquaporin 3 (AQP3) in water transport into endolymph, the K-rich, hyperosmotic fluid that bathes the apical ciliated membrane of sensory cells, and we studied the regulatory effect of dexamethasone upon AQP3 expression and water fluxes. The different AQP subtypes were identified in inner ear by RT-PCR. AQP3 was localized in human utricle and mouse inner ear by immunohistochemistry and confocal microscopy. Unidirectional transepithelial water fluxes were studied by means of (3)H2O transport in murine EC5v vestibular cells cultured on filters, treated or not with dexamethasone (10(-7) M). The stimulatory effect of dexamethasone upon AQP3 expression was assessed in EC5v cells and in vivo in mice. AQP3 was unambiguously detected in human utricle and was highly expressed in both endolymph secretory structures of the mouse inner ear, and EC5v cells. We demonstrated that water reabsorption, from the apical (endolymphatic) to the basolateral (perilymphatic) compartments, was stimulated by dexamethasone in EC5v cells. This was accompanied by a glucocorticoid-dependent increase in AQP3 expression at both messenger RNA (mRNA) and protein level, presumably through glucocorticoid receptor-mediated AQP3 transcriptional activation. We show that glucocorticoids enhance AQP3 expression in human inner ear and stimulate endolymphatic water reabsorption. These findings should encourage further clinical trials evaluating glucocorticoids efficacy in Menière's disease.

    ABSTRACT: But de la présentation L’objectif est d’améliorer les performances et le confort d’écoute des adultes implantés depuis au moins un an (Advanced Bionics) par une optimisation du réglage proposée par le logiciel FOX® (Fitting Outcoume Expert, Govaerts et al., Eargroup, Anvers). Matériel et méthodes Dix-huit adultes (9 hommes, 9 femmes), dont trois patients implantés bilatéralement (21 oreilles testées), âgés de 54 ± 17 ans (moyenne ± ET) [extrêmes : 28–78 ans] à la date de l’évaluation, et ayant un délai post-implantation de 5 ± 2 ans [2–9], ont participé à l’étude. L’évaluation se déroule en deux sessions d’environ deux heures (1 itération de réglage FOX®), à deux mois d’intervalle. Une audiométrie tonale (250 à 8000 Hz), quatre listes cochléaires de Lafon (40, 55, 70 et 80 dB), deux listes de phrases MBAA dans le bruit (S/B : 5 dB et 10 dB), un test de discrimination de 20 paires de phonèmes et une évaluation de la croissance en sonie (à 250, 1000 et 4000 Hz) ont été proposés en champ libre. Le questionnaire APHAB a également été complété. Résultats Deux mois après le réglage FOX®, les scores moyens de reconnaissance de phonèmes (Lafon) à 40 dB et 55 dB sont améliorés par rapport aux performances initiales : 4 % à la première session versus 14 % (p < 0,05) à la seconde session à 40 dB, et 33 % versus 47 % (p < 0,05) à 55 dB. À 55 dB, parmi les douze oreilles ayant les scores les plus faibles (< 40 %) lors de la première sessions six, soit la moitié, s’améliorent d’au moins 15 %. Par contre, parmi les 9 oreilles ayant des résultats supérieurs à 40 %, seule une s’améliore d’au moins 15 %. Le score global de l’APHAB (58 % vs 53 %, p < 0,05) ainsi que les domaines « facilité de communication » (45 % vs 39 %, p < 0,05) et « bruit de fond » (66 % vs 56 %, p < 0,05) sont également améliorés. Les scores aux autres évaluations ne sont ni améliorés ni dégradés. Conclusion L’utilisation du logiciel FOX® pour le réglage des implants cochléaires Advanced Bionics est possible en routine clinique et permet d’améliorer, chez certains patients, la compréhension de la parole à faible intensité et le confort d’écoute, et cela même à distance de l’implantation. Les patients avec les plus faibles résultats semblent obtenir davantage de bénéfices de cette méthode de réglage que les autres patients.

    ABSTRACT: But de la présentation Développer et pré-valider l’ECOMAS, une échelle évaluant la communication de l’adulte sourd. L’ECOMAS évalue huit domaines : « Reconnaissance de la parole », « Fluidité de l’échange », « Attitude dans la communication », « Autonomie de communication », « Intégration à des groupes sociaux », « Communication en environnement bruyant », « Communication en groupe », « Utilisation des médias ». Chaque domaine est coté de 0 à 4, soit un score total allant de 0 à 32. Matériel et méthodes Cent trente-quatre adultes sourds (76 femmes, 58 hommes) répartis en trois groupes indépendants : 39 adultes sourds candidats à l’implantation (62 ± 14 ans, [23–86]), 53 adultes implantés depuis moins d’un an (57 ± 19 ans [17–90], délai post-implant de 7 ± 4 mois, [1–12]), 42 adultes implantés depuis plus d’un an (délai post-implant de 57 ± 47 mois, [18–228]) ont été évalués avec l’ECOMAS, ainsi qu’avec la CAP, l’ERSA, les mots de Lafon/Fournier, les phrases MBAA avec un S/B de 10 dB en condition binaurale appareillée. Résultats Les scores moyens à l’ECOMAS sont respectivement de : 14 ± 7,8 sur 32 pour le groupe pré-implant (n = 39), 19 ± 6,8 pour le groupe post-implant < à 12 mois (n = 53) et 22 ± 5,5 pour le groupe post-implant > à 12 mois (n = 42). La corrélation pour chacun des trois groupes de patients entre le score total et chacun des 8 domaines (r compris entre 0,55 et 0,87, p < 0,0001), ainsi que le coefficient alpha de Cronbach de 0,9 attestent respectivement de la validité et de la consistance internes de cette échelle. La concordance inter-évaluateurs pour un même patient est très bonne entre les orthophonistes du centre référent (n = 43, coefficient Kappa > 0,8 pour les domaines, 0,68 pour le score total) mais faible entre l’orthophoniste du centre référent et l’orthophoniste de ville (n = 14, coefficient Kappa de 0,36 à 0,71 pour les domaines, 0,29 pour le score total). La validité externe entre l’Ecomas et la CAP est très bonne pour les trois groupes (r compris entre 0,69 et 0,79, p < 0,0001). Conclusion La validité interne et externe de l’ECOMAS est confirmée. Une prochaine étude aura pour objectifs d’améliorer la concordance inter-juges en développant une notice d’utilisation de l’échelle et d’évaluer la sensibilité au changement de l’échelle lors une évaluation longitudinale d’un an après l’implantation.
