The French Cochlear Implant Registry (EPIIC): Perception and language results in infants with cochlear implantation under the age of 24 months.

OBJECTIVE: Multi-centre study of the National French Registry (EPIIC) of patients with cochlear implants, focusing on infants who were operated-on under the age of 24 months between 2012 and 2016. PATIENTS AND METHODS: A total of 615 profoundly deaf infants, who received cochlear implants (CIs) before their second birthday, were included in the registry by different CI centers. Epidemiological, surgical, speech therapy and school, follow-up data were included in the registry, 12, 24, 36 and 48 months thereafter. The following parameters were studied: type of implantation (uni- or bilateral), complications, cause of deafness, category of auditory perception (CAP), Open-set word recognition score (OSW), speech intelligibility rating, lexical comprehension with EVIP (Peabody), communication mode and type of schooling. Bilateral simultaneous CI (BiCI) and unilateral CI (UniCI) groups were compared. RESULTS: There were 744 implantations. The explantation-reimplantation rate, within the four-year follow-up, was just 3.6%. Mean implantation age was 16.0 months, and similar in the two groups (BiCI/UniCI). A total of 51% of children had their first implant between 12 and 18 months, and 15% before 12 months. Implantation was unilateral in 52% of cases. Fifty-six percent of the bilateral procedures were sequential, with a mean delay of 16.8 months for the second implantation. The cause of deafness was unknown in 52% of cases. Of the 48% (297/615) of attributed cases, 32% had clear genetic causes. The remaining deafness was due to cytomegalovirus (CMV, 8%), inner-ear malformation (5%) and meningitis (3%). The main complications were from infections (47%) and internal device failure (25%). Four years post-operation, 84% of the UniCI and 75% of BiCl groups had a CAP≥5, and 83% of UniCl and 100% BiCI had OSW≥80%. Furthermore 74% of UniCI and 77% of BiCI communicated orally and 85% of UniCI and 90% of BiCI integrated into mainstream schooling. CONCLUSION: The French Registry of cochlear implants (EPIIC) is the only such national registry in the world. Our analysis illustrates the immediate benefits of, either single or double, cochlear implantation for language, perception skills and schooling.

The French Cochlear Implant Registry (EPIIC): General indicators.

Cochlear and brainstem implants have been included on the list of reimbursable products (LPPR) in France since March of 2009. The implants were initially inscribed for 5 years, after which an application for renewal with the French National Commission for the Evaluation of Medical Devices and Health Technologies (Commission Nationale d'évaluation des dispositifs médicaux et des technologies de santé - CNEDiMTS) was required [Haute Autorité de santé, 2009]. Upon registration to the list of reimbursable products, the companies and the reference centers for cochlear and brainstem implants were asked to set up a post-registration registry called EPIIC. This article reports the evolution in the EPIIC registry of the general indicators for 5051 patients over the five years from 2012-2016.

The French Cochlear Implant Registry (EPIIC): Cochlear implantation complications.

OBJECTIVES: The aim of this study was to evaluate peri- and post-operative complications related to cochlear implantations. We searched for risk factors predicting these complications and analyzed the complications in the youngest and most elderly. STUDY DESIGN: Retrospective analysis of cochlear implant patients. MATERIALS AND METHODS: All patients who underwent cochlear implantation in France between January 2012 and December 2016 were anonymized and registered in the EPIIC database. This population included 3483 adults and 2245 children. Their demographic and surgical data and their incidence of peri- or post-operative complications, including their severity, whether major or minor, were all indicated. RESULTS: The global complication rate was 6.84%. The risk of complication was higher in initial implantation versus reimplantation (P<0.0001). The risk was also higher for bilateral implantation versus unilateral (P<0.0001). Complications were more frequent for patients with cochlear malformation (P=0.002). There was no difference in complication rates across age groups; babies under 1 year old, and the elderly over 80 and even over 90, did not have more complications than the rest of the population. Patients treated in the daily care unit had no more complications than those who were hospitalized for one night or more (P=0.64). CONCLUSION: Cochlear implantation is a safe technique with a low incidence of complications. The absence of increased risk in patients at the extremes of the age spectrum justifies offering this solution to all, without age limitation.

The French National Cochlear Implant Registry (EPIIC): Cochlear implantation in adults over 65years old.

OBJECTIVES: To analyze the performance of cochlear implants in French patients aged 65 and over, implanted between 2012 and 2016, using data from the French national registry for cochlear implants (EPIIC). MATERIALS AND METHODS: The French national registry incorporates patient data from before implantation and for three years after implantation, stratified in different age groups (18-39, 40-64years, 65-74years and>75years). Here, we assessed the latter two categories. Hearing was assessed using mono- and disyllabic words in a silent background. The Category of Auditory Performance (CAP) scale was also implemented and subjects took the Abbreviated Profile of Hearing Aid Benefit (Aphab) questionnaire. RESULTS: The population aged over 65 accounted for 38% (n=1193) of the 3178 adult implanted patients. The performance for mono- and disyllabic words in silence, the CAP scores and the APHAB questionnaire answers for ease of communication, background noise and reverberation were dramatically improved at one year post-implantation (P<0.0001 for each score) and remained stable between one and three years thereafter. The percentage improvement was similar across all age groups. The scores for loud-noise intolerance did not change after cochlear implantation in any age group. CONCLUSION: Cochlear implants improve hearing and communication in subjects aged 65 and over, with comparable efficiency to that achieved in younger subjects. Cochlear implantation should thus be proposed whenever hearing aids provide only limited benefit. However, between 2012 and 2016, cochlear implantation was given to less than 1% of the French population aged 65 and over with profound deafness.

The French National Cochlear Implant Registry (EPIIC): Results, quality of life, questionnaires, academic and professional life.

This study concerns the results of cochlear implantation in children and adults from French cochlear implantation centers, monitored at one, two and three years by the Cochlear Implant French Registry EPIIC. This multicenter study enrolled 2603 subjects (1667 adults and 936 children) implanted in one ear. The following parameters were studied: hearing overall performances, monosyllabic or dissyllabic word perception, speech intelligibility, self-assessment questionnaire of Cochlear Implant (CI) benefits (Abbreviated profile of Hearing aid Benefit); professional activity and schooling. This study confirms the ceiling effect in adults' performances after the 1st year and the progressive growth in children's performances. It also shows that the contralateral hearing aid enhances performances compared to the CI alone condition, in all follow-up sessions. The French register of CIs is the only worldwide register of systematic follow-up on a period of three years and more of all adults and children implanted in a country.

The French Cochlear Implant Registry (EPIIC): Cochlear implant candidacy assessment of off-label indications.

OBJECTIVE: Evaluate in France the outcomes of cochlear implantation outside the selection criteria, off-label. MATERIAL AND METHODS: This is a prospective cohort study including adults and children having received a cochlear implant (CI) in an off-label indication, that is outside the criteria established by the "Haute Autorité de santé (HAS)" in 2012. The data was collected from the "EPIIC" registry on recipients who received CIs in France between 2011 and 2014. Speech audiometry was performed at 60dB preimplantation and after one year of CI use, as well as an evaluation of the scores of the quality of life with the APHAB questionnaire, the scores for CAP and the professional/academic status in pre- and post-implantation conditions. Major and minor complications at surgery have been recorded. RESULTS: In total, 590 patients (447 adults and 143 children) with an off-label indication for CIs were included in this study from the EPIIC registry (11.7% of the whole cohort of EPIIC). For adults, the median percentage of comprehension using monosyllabic word lists was 41% in preimplantation condition versus 53% after one year of CI use (P<0.001) and 60% versus 71% in dissyllabic word lists (P<0.001). The CAP scores were 5 versus 6 in pre- and post-implantation conditions respectively (P<0.001) and the APHAB scores were statistically lower after implantation (P<0.001). In the children cohort, the median percentage of comprehension using monosyllabic word lists was 51% in preimplantation condition and 65% after CI (P<0.001), and 48% versus 82% (P<0.001) for dissyllabic word lists. The CAP scores were 5 versus 7 respectively in pre- and post-CI conditions (P<0.001). Thirty-two minor complications (5.4%) and 17 major complications (2.8%) were reported in our panel of off-label indication patients. CONCLUSION: These results suggest that a revision of the cochlear implantation candidacy criteria is necessary to allow more patients with severe or asymmetric hearing loss to benefit from a CI when there is an impact on quality of life despite the use of an optimal hearing aid.

The French National Cochlear Implant Registry (EPIIC): Cochlear explantation and reimplantation.

This study aims to determine the frequency and causes of cochlear explants with re-implantation (ERI) after 5 years' follow up of the patients included in the French national EPIIC (étude post-inscription des implants cochléaires) registry tracking patients with cochlear implantation. This multicenter, descriptive prospective study was conducted on 5051 patients enrolled in the EPIIC database between January 2012 and December 2016. Ninety-five patients (1.9%) received a primary implant and an ERI during the study. Of these, four benefitted from two ERIs. The number of ERIs was significantly higher in the pediatric population than among adults. The explantation and reimplantation were performed simultaneously in 86% of cases. The reasons for explantation were: in 46.4% of cases linked to a malfunction of the implant, and in 39.3% of cases for medical or surgical reasons. The number of electrodes inserted was significantly higher after the ERI than after the first implantation. There was just one post-ERI infection for these 95 explanted and re-implanted patients. As well as explantation with reimplantation rarely being necessary, it generally presents no major surgical difficulty and in most cases it allows a better integration than in the first implantation.

The French National Cochlear Implant Registry (EPIIC): Bilateral cochlear implantation.

OBJECTIVES: Assessment of the incidence and results of bilateral cochlear implantation in adults and children in France. MATERIALS AND METHODS: Multicenter retrospective study of data in the French national registry of cochlear implantations from January 1st 2012 to December 31st 2016. Functional results from CAP (Category of Auditory Performance) questionnaires and speech audiometry tests, with mono- and di-syllabic word-lists, were compared before and after implantation. Speech audiometry tests were carried out against a noisy background, except before simultaneous implantations. RESULTS: Nine hundred and forty two bilateral cochlear implantations were performed during this period, that is, 16.4% of all cochlear implantations. Five hundred and eighty eight bilateral implantations were performed sequentially. 59% of the bilateral implantations were performed in children. Bilateral implants significantly improved CAP scores in all cases (P<0.001). Auditory performance, with the two types of word-list, were significantly improved after simultaneous implantation (P<0.01). After sequential implantation, the speech discrimination score, already very good with the first implant, reached 63±26% [0-100] with monosyllabic word lists, and 72±28% [0-100] with dissyllabic words. There were more complications due to surgery in bilateral cases than in the entire population of cochlear recipients (9.1% vs 6.4%, P<0.02). CONCLUSION: Hearing is significantly improved by simultaneous cochlear implantation. For sequential implantation, at one year, when auditory results were already excellent from the first implant, in the bimodal condition CAP scores were significantly improved, although there was no further change in speech audiometry in noise.

Surgical reconstruction of the foramen tympanicum: What is known and how we do it.

Defects affecting the anterior wall of the tympanal bone can result from trauma, infection, neoplasm or previous local surgery. An anatomic variation, namely the persistence of the foramen tympanicum, can also be encountered. When symptomatic, surgical reconstruction may be indicated. The aim of this study was to identify the surgical treatments of symptomatic foramen tympanicum found in the literature and detail our innovative reconstruction technique. A bibliographic research was conducted in PubMed database in March 2020, without time limitation. Papers dealing with surgical management of a foramen tympanicum were included. Data collected were the publication date, the number of patients, their age and gender, the symptoms and the surgical treatment performed. We report, in addition, the case of a symptomatic persistent foramen tympanicum in a 30-year-old man with a follow-up of 18-months. A total of 17 studies (n=23 patients) were included for analysis. The main reconstruction techniques were, in equal proportion, cartilage graft (30%) and insertion of a titanium mesh (30%). We carried out an iliac crest bone graft using a preauricular approach on a patient suffering from chronic tinnitus and fullness in the left ear resulting from a persistent foramen tympanicum, confirmed by clinical and radiological examinations. It allowed the complete resolution of symptoms and no complication such as temporomandibular ankylosis occurred. Based on the review of the literature, we believe this technique has the advantage of providing durable reconstruction thanks to osseointegration.

Neuropathic pain at diagnosis of head and neck squamous cell carcinoma.

OBJECTIVE: To assess the prevalence and characteristics of neuropathic pain (NP) at diagnosis of head and neck squamous cell carcinoma (HNSCC) and its impact on nutritional status and treatment tolerance. MATERIALS AND METHODS: Patients treated for HNSCC between January 1, 2018 and January 30, 2019 were included. Pain was assessed prospectively on the DN2 and NSPI scales. Epidemiological characteristics, nutritional status and treatment tolerance were collected. Two groups were distinguished according to absence or presence of neuropathic pain (NP-, NP+). RESULTS: Sixty patients were included. NP prevalence at diagnosis was 54%, mainly involving locally advanced oral cavity and oropharyngeal tumors. There was a significant intergroup difference in nutritional status, with 62% malnutrition in NP+ versus 32% in NP- (p=0.0321). There was no such difference in tolerance. CONCLUSION: NP is frequent at diagnosis of HNSCC. Early diagnosis on a simple validated score can help improve quality of life and nutritional status.

Epistaxis complicating treatment by anti-vitamin K and new oral anticoagulants.

OBJECTIVES: To assess any differences in severity and management of epistaxis when complicating treatment by anti-vitamin K (AVK) or by new oral anticoagulants (NOAC). MATERIALS AND METHOD: All patients admitted to the ENT department of a University Hospital Center for epistaxis under oral anticoagulation therapy between January 2010 and June 2015 were included in a retrospective study. Severity was assessed in terms of management and of hemoglobin level at admission. Two groups were distinguished: treatment by AVK or by NOAC. RESULTS: One hundred and thirty-four patients were included: 126 under AVK and 8 under NOAC. There was a significant difference in mean hospital stay: 4.5 days for AVK versus 3.5 days for NOAC (P=0.019; 95% CI [0.1921; 0.8907]). There were no significant differences for the other severity criteria. None of the patients died. CONCLUSION: Admission rates for epistaxis complicating NOAC therapy was low, and much lower than in case of AVK. Bleeding severity was equivalent with both treatments. NOACs significantly reduce hospital stay. Contrary to the study hypothesis, epistaxis is less serious when complicating NOAC than AVK therapy.

Polymyalgia rheumatica and vagal paraganglioma.

INTRODUCTION: Vagal paraganglioma are rare tumors that are mostly asymptomatic. We report a case of vagal paraganglioma associated with paraneoplastic polymyalgia rheumatica and review the literature on benign paragangliomas of the head and neck associated with paraneoplastic syndrome. CASE REPORT: A 53-year-old man presented with atypical polymyalgia rheumatica. MRI revealed a tumor that was then surgically excised. Histological examination confirmed the diagnosis of benign vagal paraganglioma. Rapid, complete and permanent resolution of all rheumatological symptoms were observed postoperatively, confirming the diagnosis of paraneoplastic polymyalgia rheumatica. CONCLUSION: Paraganglioma of the neck associated with paraneoplastic syndrome remains exceptional. A predisposing gene mutation must be systematically investigated. Long-term surveillance must be ensured due to the risk of local recurrence, second tumors or metastasis.

[Stereomodel-assisted fibula free flap harvest and mandibular reconstruction: A technical note. Literature review of CAS and CAM applied to mandibular reconstruction]. / Reconstruction de la mandibule par lambeau libre de péroné assistée par une maquette tridimensionnelle : note technique. Revue de la littérature des techniques de CAO et FAO appliquées à la reconstruction mandibulaire.

PURPOSE: Mandibular reconstruction with fibula free flap harvest is currently the reference technique. Various preoperative processes have been developed to optimize this reconstruction. We report our experience with a simple, inexpensive, preoperative technique requiring a 3D printer, a device for maintaining mandibular reduction, a paper-cutting guide. TECHNICAL NOTE: Stereomodels of the mandible were obtained from computed tomography scan data and printed 3D in ABS. It allowed planning mandibular osteotomies, determine the angle between two bone fragments, and preoperatively modeling the osteosynthesis plate. A paper-cutting guide, and a simple device for maintaining mandibular reduction were also built. Two patients were operated on with this technique, with follow-up at 6 and 8 months. Reconstructions were successful with good clinical outcome in terms of mandibular contour and reconstructed segments positions. DISCUSSION: Preoperative planning of reconstruction may be used for mandibular osteotomies, fibular osteotomies, maintaining mandibular reduction, osteosynthesis, or placing implants for dental rehabilitation. The most complex procedures can virtually plan all these steps, but they are expensive and long to implement. Nevertheless, such procedures are quite expansive and require time not always compatible with carcinoma. Using a mandibular stereomodel is fast, easy, and cheap.

[Acinic cell carcinoma in an ectopic salivary gland]. / Carcinome à cellules acineuses d'une glande salivaire ectopique.

On the occasion of the coverage of a cervical tumefaction in a child, which led to the diagnosis of acinic cell carcinoma of ectopic salivary gland, the authors conducted a literature review of this tumour. If it is well known to pathologists when it is developed in the major or accessories salivary glands, its location within heterotopy of salivary tissue is much rarer. From a histological point of view it is difficult to distinguish, if primitive location, the occurrence of the tumour in an ectopic salivary gland, its occurrence in intra-node heterotopic salivary tissue. This distinction between glandular ectopia and intra-node heterotopia remains purely theoretical, and does not affect the therapeutic decision. This one remains empirical and discussed on a case-by-case basis for a malignant tumour that is exceptional in this location and at that age.

[Inflammatory pathology and rhinosinusal CT scan: the radiologist's report]. / Pathologie inflammatoire et scanner rhinosinusien: le compte rendu du radiologue.

OBJECTIVE: Pave the way to a better management of the chronical rhino-sinusitis diseases: Description and classification of the chronical rhino-sinusitis pathology, its medical and surgical treatments in order to help the radiologist in its CT-scan report. MATERIAL AND METHOD: Review of the literature and anatomical considerations. Paranasal sinuses CT-scan analysis. RESULTS AND CONCLUSION: The execution and the interpretation of CT-scans, in accordance with the progress made in the past 20 years in the knowledge of the rhino-sinusitis physiology and pathology, are today absolutely necessary for the management of chronical rhino-sinusitis diseases.

[Mild head trauma: complications and acousticovestibular sequelae]. / Traumatismes crâniens légers: complications et séquelles audio-vestibulaires.

Head injury with fracture of the petrous bone is frequent and directly related to the development of human activity. Head trauma is associated with nearly 75% of traffic accidents; 5% of them with petrous bone fracture. Based on a clinical case, the acute injuries and secondary acoustic or vestibular sequelae after low-energy cranio-cerebral trauma are discussed here. The subject was a victim of a low-energy head trauma with brief loss of consciousness and translabyrinthine fracture of the petrous bone. This fracture caused invalidating equilibrium disorders related to a perilymphatic fistula. These disorders persisted for 3.5 years and required several hospitalizations and three surgical procedures. The acoustic problems progressed towards cophosis and persistent and invalidating tintinus. We discuss the pathogenesis and treatment of these different sequelae of the middle ear as well as the external lesions. Among labyrinthine involvement, especially unilateral destruction, fistulization, concussion, and post concussion syndrome are especially descripted. Bony dislocations dominate middle ear sequelae. We also discuss the medicolegal problems associated with this type of pathology.

Influence of individual competition level on back kinematics of horses jumping a vertical fence.

REASONS FOR PERFORMING STUDY: The costs and investments required for the purchase and training of showjumpers justify the need to find selection means for jumping horses. Use of objective kinematic criteria correlated to jumping ability could be helpful for this assessment. OBJECTIVES: To compare back kinematics between 2 groups of horses of different competition levels (Group 1, competing at high level; Group 2 competing at low level) while free jumping over a 1 m vertical fence. METHODS: Three-dimensional recordings were performed using 2 panning cameras. Kinematic parameters of the withers and tuber sacrale (vertical displacement, vertical and horizontal velocities), backline inclination and flexion-extension motion of the 3 main dorsal segments (thoracic, thoracolumbar and lumbosacral) were analysed. RESULTS: Group 2 horses had a lower displacement of their withers and tuber sacrale from the end of the last approach stride until the first departure stride (P<0.05). As a result, they increased the flexion of their thoracolumbar and lumbosacral junctions during the hindlimb swing phase before take-off (P<0.05). However, withers and tuber sacrale velocities were slightly modified. Group 1 horses pitched their backline less forward during the forelimb stance phase before take-off and straightened it more after landing (P<0.05), probably indicating a more efficient strutting action of their forelimbs. CONCLUSIONS AND POTENTIAL RELEVANCE: Because significant differences in back motion were found between good and poor jumpers when jumping a 1 m high fence, criteria based on certain back kinematics can be developed that may help in the selection of talented showjumpers.
