Outcomes at 6 months after isolated or non-isolated surgery for temporal bone cerebrospinal fluid leak in adults: A STROBE analysis.

AIM: The main aim of this study was to evaluate 6-month closure success in surgery for isolated or non-isolated temporal bone osteomeningeal breach (OMB). Secondary objectives were to analyze complications of closure and correlations between success and breach, treatment and patient data. MATERIAL AND METHOD: This was a single-center retrospective observational study of patients who underwent surgery for temporal bone OMB via a middle cranial fossa or transmastoid approach in a French university teaching hospital between 2007 and 2022, with follow-up of at least 6months. Patients with superior semicircular canal dehiscence were excluded. Study data comprised gender, age, body mass index, OMB etiology, mode of discovery, audiometric and radiological data, surgical technique, length of hospital stay and postoperative complications. The primary endpoint was absence of a cerebrospinal fluid leak on MRI at 6months. Fisher's exact test or Chi2 test were used for qualitative data and Student t-test for quantitative data. RESULTS: The closure success rate was 87%: 81% (3 recurrences) in the middle cranial fossa group of 16 patients and 93% in the transmastoid group of 14 patients. Postoperative audiometry showed significant improvement (P=0.0016) for air conduction in the middle cranial fossa group. Five patients (17%) operated on via the middle cranial fossa approach and 1 (7%) operated on via the transmastoid approach had postoperative complications. OMB was in the tegmen mastoideum in 8 patients (29%), tegmen tympani in 7 (25%), tegmen antri in 4 (14%), tegmina antri and tympani in 3 (11%), antri and mastoideum in 1 (8%) and in the whole tegmen in 5 (18%). Eleven OMBs were lateral to the superior semicircular canal, 13 medial and 4 on either side. CONCLUSION: The transmastoid approach is indicated in case of associated middle-ear procedures, patients aged over 75years or OMB lateral to the superior semicircular canal. The middle cranial fossa approach is reserved for OMB located medial to the superior semicircular canal patients under 75years of age without associated ossicular procedures. For patients with OMB medial to the superior semicircular canal who require middle-ear surgery, a combined approach can be used.

Safety of middle-ear day-surgery in children: A STROBE observational study.

OBJECTIVE: The main objective of this pediatric study of otologic surgery was to analyze factors for success of outpatient management. The secondary objective was to study unscheduled postoperative consultations and readmissions. MATERIALS AND METHODS: This retrospective observational study analyzed clinical characteristics and procedures in consecutive children undergoing major ear surgery over a 3-year period in a teaching hospital. The study followed STROBE recommendations. RESULTS: We included 214 day-cases from a total population of 271 children. Median age was 109±44months (9years) [range: 8-196months (16years)]. In 57% of cases, the procedure was performed without mastoidectomy: 84 myringoplasties and 37 tympanoplasties. In 43% of cases, mastoidectomy was associated: 47 cochlear implants and 46 closed tympanoplasties for cholesteatoma. Ninety-five percent of day-surgeries were successful; in 5%, there was crossover to pediatric ENT department admission, for the following symptoms: postoperative nausea and vomiting in 3 cases, pain in 3, and late awakening in 5. Univariate analysis showed a relationship between failure and age under 36months (P=0.002). There were no readmissions. There were unscheduled consultations in 3% of cases: for minor otorrhagia in 5 cases and uncomplicated otorrhea in 2. CONCLUSION: Major otologic surgery in children is compatible with day-surgery. Younger patients, usually candidates for cochlear implantation, had greater risk of crossover to conventional admission. In this age group, scheduling should be earlier in the morning, with rigorous postoperative nausea and vomiting prophylaxis.

Otosclerosis surgery under local anesthesia with sedation: Assessment of quality of life and stress.

OBJECTIVES: The main study endpoint was tolerance of stapedotomy under local anesthesia with sedation and under general anesthesia using stress and quality of life assessment questionnaires. Secondary endpoints comprised operative time and functional results. MATERIAL AND METHOD: In a consecutive series of stapedotomy patients operated on over a 12-month period, quality of life and perioperative stress were analysed by 3 questionnaires: the Glasgow Benefit Inventory, Cohen's perceived stress scale and the Post-traumatic stress disorder checklist scale. Questionnaire responses and audiometric data were compared between groups treated under local anesthesia with sedation and under general anesthesia. RESULTS: Twenty-two patients were included in the local anesthesia with sedation group and 6 in the general anesthesia group. There was no difference between the groups for quality of life, onset of post-traumatic stress, or perceived pre- and postoperative stress. There was also no difference in operative time. The audiometric data confirmed the reliability of stapedotomy. Stapedotomy under local anesthesia with sedation improved air conduction with≤10dB air-bone gap (ABG), comparable to results under general anesthesia. The rate of ABG≤10dB was 71.4%; no labyrinthisation was observed. CONCLUSION: Under local anesthesia with sedation, stapedotomy was well tolerated without increasing the stress associated with otosclerosis surgery. By correcting hearing loss, the procedure improves quality of life.

Stapes surgery for otosclerosis under local anaesthesia with sedation.

The stapes surgery surgical technique has now been clearly standardized, ensuring a reliable and reproducible procedure with a satisfactory success rate. The possibility of performing this surgery under local anaesthesia with sedation requires very good collaboration between surgeons and anaesthetists. The patient is informed about the various steps of the operation to ensure that he or she is reassured both before and during the procedure. Local anaesthesia with sedation constitutes an alternative in patients afraid of general anaesthesia. Sudden onset of dizziness reported by the patient during the operation after piston placement may be due to an excessively long piston, which may need to be adjusted. We describe the technique used in our centre. In the literature, there is no difference in terms of audiometric performance and dizziness between patients operated under local anaesthesia with sedation or general anaesthesia.

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 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 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): 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 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 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): 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.

COVID-19 and ENT Surgery.

In Otorhinolaryngology - Head and Neck Surgery, clinical examination and invasive procedures on the respiratory tract and on airway-connected cavities, such as paranasal sinuses and the middle ear, expose people to direct transmission of SARS-CoV-2 by inhalation or ocular projection of contaminated droplets, and to indirect transmission by contact with contaminated hands, objects or surfaces. Estimating an R0 of COVID-19 at around 3 justified postponing non-urgent face-to-face consultations and expanding the use of teleconsultation in order to limit the risks of SARS-CoV-2 infection of patients or health workers and comply with the lockdown. The health authority recommends cancellation of all medical or surgical activities, which are not urgent as long as this does not involve a loss of chance for the patient. The purpose of this cancellation is to significantly increase critical care capacity, prioritise the reception of patients with COVID-19, prioritise the allocation of staff and provision of the equipment necessary for their medical or surgical management, and contribute to the smooth running of downstream critical care within their establishment. Another goal is to reduce the risks of patient contamination within healthcare facilities. This document provides guidance on how to proceed with and adapt ENT surgery in the current pandemic context, as well as on the management of postponed operations. This best practice advice must of course be adapted in each region according to the development of the epidemic and pre-existing arrangements. Their local application can only be decided within the framework of collaboration between the ENT teams, the operational hygiene units and all the other specialties concerned.

Best practice recommendations: ENT consultations during the COVID-19 pandemic.

These best practice recommendations for ENT consultations during the COVID-19 pandemic have been drawn up because ENT examinations and treatments are at risk of contamination by the SARS-Cov-2 virus in certain instances. Thus, ENT specialists are among the professionals who are most exposed to this infection. During the pandemic, insofar as an asymptomatic patient may be infected and contagious, the same precautions must be employed whether the patient is ill with, suspected of having, or without any clinical evidence of COVID-19 infection. According to the scientific data available, the examinations and procedures potentially exposing to projections/aerosolizations of organic material of human origin are considered to be at risk of staff contamination. For ENT examinations and procedures without exposure to such projections/aerosolizations, the professional is advised to a long sleeve clean outfit, a surgical mask and gloves in case of contact with the patient's mucosa. ENT examinations and procedures with exposure to these projections/aerosolizations require the so-called "airborne", "contact", and "droplets" additional precautions: FFP2/N95 respiratory protection device, eye protection, disposable headwear and long sleeve overgown.

COVID-19 and ENT Pediatric otolaryngology during the COVID-19 pandemic. Guidelines of the French Association of Pediatric Otorhinolaryngology (AFOP) and French Society of Otorhinolaryngology (SFORL).

OBJECTIVE: Joint guidelines of the French Pediatric Otolaryngology Society (AFOP) and of the French Society of otorhinolaryngology-head and neck surgery (SFORL) on the management of paediatric otolaryngology patients in the context of the COVID-19 pandemic. METHODS: A nation-wide workgroup drew guidelines based on clinical experience, national and local recommendations and scientific literature. Proposals may have to be updated on a day-to-day basis. RESULTS: In children, incidence of symptomatic COVID-19 (1-5%) is low and of good prognosis. The indications for nasal flexible endoscopy should be drastically limited. If undertaken, full Personal Protective Equipment (PPE) including FFP2 masks are required, as well as use of a sheath. Saline nose wash done by caregivers other than parents at home should require PPE. Unless foreign body tracheobronchial aspiration is clinically obvious, CT-scan should be performed to confirm indication of endoscopy. Surgical indications should be limited to emergencies and to cases that cannot be delayed beyond 2 months (especially endonasal, endopharyngeal laryngo-tracheobronchial procedures). Postponement should ideally be a group decision and recorded as such in the medical file. Surgical techniques should be adapted to limit the risk of viral dissemination in the air, avoiding the use of drills, microdebriders, monopolar cautery or lasers. Continuous suction should be placed near the operating field. In case of confirmed Covid-19 cases, or suspected cases (or in some centres systematically), PPE with FFP2 mask should be worn by all staff members present in the operating room.

Reform of the 3rd cycle in surgery training.

The main objectives of the reform of the 3rd cycle of medical studies in France that was instituted in 2017 after eight years of preparation, are to train future specialists in a consistent and equitable fashion and to replace the previous time-based qualification by training based on the progressive acquisition of skills. This reform was an opportunity for the 13 different French surgical specialty Colleges involved to share reflections on what a surgeon actually was and to define training in surgical sub-specialties. The current reform is well adapted to these specifications and has fostered training models that are consistent with each other. This article discusses the historical construction of this reform, what will change in the training of future surgeons, as well as some points that warrant caution. The third cycle reform has also triggered a reform of the second cycle, which is expected to come into force for the 2020 academic year. Its objective will be to eliminate the guillotine effect created by the National Classifying Examinations and to allow students to better understand and test their desire and skills for a given specialty. It will be up to these same surgical Colleges to determine how to do this for the sub-specialties of the "surgery" discipline.

French consensus on management of head and neck cancer surgery during COVID-19 pandemic.

In the context of the current pandemic, there is a need for specific advice concerning treatment of patients with Head and Neck cancers. The rule is to limit as much as possible the number of patients in order to reduce the risks of contamination by the SARS-Cov-2 virus for both patients and the caregivers, who are particularly exposed in ENT. The aim is to minimize the risk of loss of opportunity for patients and to anticipate the increased number of cancer patients to be treated at the end of the pandemic, taking into account the degree of urgency, the difficulty of the surgery, the risk of contaminating the caregivers (tracheotomy) and the local situation (whether or not the hospital and intensive care departments are overstretched).

Otosclerosis surgery: Assessment of patient comfort.

OBJECTIVES: To evaluate operative comfort and stress in patients undergoing stapedotomy for otosclerosis under local versus general anesthesia. MATERIAL AND METHODS: Consecutive otosclerosis patients managed over a 9-month period responded to 3 validated questionnaires to assess peri- and post-operative comfort: Glasgow Benefit Inventory, Cohen's Perceived Stress Scale and the Posttraumatic Stress Disorder Checklist Scale. These results and audiometric data were compared between local and general anesthesia groups. RESULTS: Twenty-one patients were included in the local anesthesia group and 7 in the general anesthesia group, after exclusion of patients with history of otosclerosis surgery. There was no significant inter-group difference on Glasgow Benefit Inventory (P=0.38) or Posttraumatic Stress Disorder Checklist Scale (P=0.86). Perceived Stress Scale scores were higher in the general anesthesia group (P=0.038). In total, 67% of patients reported no discomfort under local anesthesia, and 86% were ready to undergo the procedure under local anesthesia again. There were no significant differences in postoperative symptoms, or in air-bone gap≤10dB (local anesthesia 81%, general anesthesia 71%; P=0.156). CONCLUSIONS: Local anesthesia in otosclerosis surgery did not increase stress or postoperative symptoms compared to general anesthesia. Audiometric results were not affected by type of anesthesia.
