Les dents sont en relation étroite avec les systèmes digestif, respiratoire, cardiovasculaire et endocrinien. Elles ont une relation privilégiée avec les voies aériennes supérieures, en particulier les sinus. La pathologie sinusale peut se manifester en bouche, comme la pathologie dentaire peut se manifester dans les sinus. La respiration nasale est indispensable au développement maxillaire. Nous sommes souvent sollicités pour les corps étrangers sinusiens, les fistules oro-antrales et les implants dentaires. [less ▲]

Background Lack of data regarding efficiency of simulation-based teaching, in particular high-fidelity virtual reality, constitutes a major drawback for its implementation in the medical training. However, it provides a structured, safe and supportive environment to familiarize with complex anatomy and practice surgical skills. We aimed to evaluate high-fidelity virtual reality simulation in learning of temporal bone radio-anatomy during ENT residency. Materials and Methods 15 Belgian otorhinolaryngology residents completed 5 sessions of simulation in antro-mastoidectomy using VOXEL-MAN Tempo® surgical simulator. Technical mistakes and surgical parameters were recorded. Before and after training period, residents completed a temporal bone radiological anatomy test available online (http://www.radioanatomie.com). Pre- and post-simulation scores were compared as primary endpoint by non-parametric Wilcoxon test using RCmdr (https://www.r-project.org). As secondary endpoint, residents’ surgical skills following simulation training were blindly assessed on cadaveric human temporal bones using a reproducible scale by seniors otologist surgeons of our department. Correlation between radiological testing and dissection scale were evaluated by Spearman regression. Finally, trainees completed a survey on the device itself. Results Performance on radiological testing significantly increased with a mean improvement of 28 ± 12.12 (Wilcoxon p = 0.0011). Surgical results on cadaveric specimens were not correlated to surgical simulation parameters. Higher results on radiological testing were associated with higher scores on dissection scale, suggesting that subjects who succeeded better at dissection were those who knew best anatomy. Among residents, 80% felt this tool suitable for early surgical education, and 84.6% queried further information on simulation techniques. 100% of trainees would integrate this tool within their learning of temporal bone's radiological and surgical anatomy. Conclusions High-fidelity virtual reality simulator improved temporal bone anatomy teaching and specifically increased knowledge of temporal bone radiological anatomy. Acknowledgement No conflict of interest. [less ▲]

Introduction and Aim: We aimed to evaluate high-fidelity virtual reality simulation in learning of temporal bone radio-anatomy during ENT residency. Methods: Fifteen ENT residents completed a radiological temporal bone anatomical testing before and after five training sessions on the VOXEL-MAN Tempo® surgical simulator. Secondary investigation: residents also completed a personal subjective assessment after these training session and residents’ technical skills were assessed on cadaveric temporal bones. Results: Primary outcome: Residents significantly improved their performance on the temporal bone radiological anatomy test after completing virtual training on the simulator. Secondary outcomes: The personal assessment survey indicated that 100% of the residents would integrate this virtual tool within the learning methods. No significant correlation was found between virtual simulator performances and surgical performances on cadaveric model, but a significant correlation was shown between the anatomical testing result and the performances on cadaveric model. Conclusions: This study suggested that a high-fidelity virtual reality simulator, the VOXEL-MAN Tempo® device, improved teaching of temporal bone anatomy and specifically increased trainees’ practical knowledge regarding radiological anatomy of temporal bone.

Introduction and Aim: Rapid maxillary expansion devices are used in children with upper maxillary transverse deficit and cross-bite. They were consistently shown to improve obstructive apnoea syndrome in children. However, the impact of the device in place into the child’s mouth has never been studied. The aim of our study was to quantify the effect of the device on respiratory events while in place. Secondary endpoints were to evaluate its impact on quality of life and on respiratory events after treatment. Material and Methods: 12 consecutive children with maxillary cross-bite were prospectively included in this cohort study. Respiratory events were recorded before, during and after rapid maxillary expansion using a validated type 3 polygraphy including jaw movements. Subjective outcomes were evaluated using Obstructive Sleep Apnea (OSA)-18 quality-of-life questionnaire (OSA-18). Maxillary width and 16/26 distance were evaluated before and after rapid maxillary expansion on anterior radiography. Results: Estimated apnea hypopnea index increased from 2.67/h (±1.31/h) to 2.9/h (±2.4/h) with the device in place. Respiratory effort characterized by jaw motion > 0.4mm during the respiratory cycle increased from 7.58% (±10.01%) to 16.05% (±15.53%). Sleep-related breathing impairment was confirmed by parents’ questionnaires. Conclusion: While rapid maxillary expansion is an effective treatment for obstructive apnea syndrome in children, our study suggested a transient worsening of sleep breathing while the device is in place. It may be related to an incorrect tongue position and/or to the crowding of the device into the mouth. [less ▲]

Introduction and Aim: A shift in Obstructive Sleep Apnea (OSA) funding was implemented in Belgium on January 1, 2017. Funding was allowed for moderate to severe OSA and the rules shifted for treatments delivery and monitoring by authorised medical opinion. Multidisciplinary Sleep Clinics have long existed, bringing together sleep specialists, dentists, orthodontists and surgeons. We aimed to assess whether a shift in treatment funding was associated with a change in the multidisciplinary sleep practice. Material and Methods: Sample consisted of all patients discussed in the sleep multidisciplinary team meetings of the University Hospital of Liege from January 2016 to December 2018. Interrupted times series, Mann-Whitney U tests and descriptive statistics were produced. Results: There were no differences in patients age, male sex preponderance, body mass index, clinical presentation and level of obstruction. Baseline OSA severity was significantly lower (mean apnea-hypopnea index and mean oxygen desaturation index lowered respectively with p = 0.0189 and p = 0.0466) after the funding rules changed. Oral appliance and ENT surgery were more often offered after the shift in funding. Conclusion: Sleep multidisciplinary team meeting changed patient selection and management after the implementation of the new funding rules for OSA. The shift in funding often resulted in treatment options change, reaching more people and offering more options. [less ▲]

Introduction and Aim: This study aimed to draw up an inventory of the current practical training from the surgical trainees’ point of view, identifying strengths and gaps of current training and potential tools to be developed. Material and Methods: We conducted a broad national survey among Belgian population within the North-part and South-part universities of the country. The questions included self-assessment, training objectives, training quality and training tools. Results: 35.7% of trainees evaluated their level of overall surgical competence at 3/5 compared to an ideal mastery. More than a half (55%) of trainees did not know the training objectives and 73% did not know the basic surgical procedures that a qualified ENT surgeon should be able to perform. The main mode of learning (41%) was the observation of a senior and repetition under supervision (companionship). The results showed mainly logistical and economic drawbacks, on which it seems possible to act using learning methods based on the implementation of organized training sessions, associated with different learning tools such as surgical and procedural simulation. Some of these are already available in our country but remain difficult to access or to develop. Conclusion: This study revealed a real demand and motivation from trainees and could serve as a basis to sketch a teaching scheme improving skills and confidence of future surgeons. Additional studies are needed to identify the most effective ways for implementing this type of teaching within the constraints of the surgical curriculum and teaching hospitals resources. [less ▲]

The nose is the input channel for the airflow. Its rigid and erectile structures determine the outline and the output of the airflow in the upper airway. Nose obstruction, due to reversible or non reversible factors, produces collapsing forces that are manifest downstream in the collapsible pharynx. Moreover, nose pathologies result in unstable oral breathing, decreased activation of nasal-ventilatory reflex and reduced lung nitric oxide. Long-term oral breathing impacts on the craniofacial growth. The management of nose pathologies coud be medical, mechanical (nose dilators) or surgical. Nasal management should be integrated in a multimodal approach, considering the involvement of a multi-level obstruction, and truly reflecting the complexity of sleep disordered breathing. [less ▲]

Il est intéressant pour les patients et les soignants de développer des collaborations entre services, qui mettent en commun leurs compétences, leurs atouts et leurs difficultés. Les dents ne sont actuellement plus uniquement considérées comme l'os servant à mordre et broyer. Elles font partie d'un système digestif et respiratoire indispensable à la santé du patient. Dans ce module seront revus les relations entre les dents et les voies aériennes supérieures, en particulier les sinus.

Aims: Increasing pressure to reduce healthcare cost threatens the provision of acute ENT coverage round the clock. Our goal was to audit our emergency rhinologic activity over a one-month period. Methods: A prospective audit for all emergency ENT referrals was carried out from May 1st to May 31th 2017. Descriptive statistics were produced for age, sex, origin, time of arrival, diagnosis and outcome. A specific subgroup analysis was performed for rhinologic emergencies. A basic cost analysis was ran. Results: Over the study period, 190 patients were referred to the ENT emergency service. Twenty percent patients presented with nose or sinus complaint (36.8% with otological or neuro-vestibular primary complaint, 43.2% with laryngeal or neck complaint). Nose and throat complaints were more likely to present at night or on weekends. Ear complaints were more likely to present during business hours. Rhinologic complaint was more likely to require technical or surgical management than ear or throat complaint. Patients with nose complaint required minor procedure in 43.2% cases (35.6% of the total minor procedures), and required surgical procedure in 13.5% cases. Among the total ENT emergency surgical procedures, 62.5% were rhinologic ones, involving the nose (50%) or the sinus (12.5%). Ear or throat initial complaint were more likely to require no treatment or ambulatory management. Conclusion: The emergency rhinologic activity is justified in our hospital. An initial rhinological complaint was more likely to require specific ENT management than other complaints. ENT cover is an efficient service provision, especially for rhinologic emergencies.

Aims: SNOT-22 was initially designed for rhinosinusitis, but was recenty validated in various nose conditions. Nose or sinus complaint is a common cause of consultation in primary care or ENT clinic. Therefore we sought to optimize the simple and versatile instrument SNOT-22. Our aim was to determine the outcome of patients and healthy volunteers solely based on the pattern of the baseline SNOT-22 in a multi-centre study. Methods: Sixty-six healthy volunteers and 383 patients presenting to the rhinology clinic of the ENT academic departments of Godinne, Liege and Brussels participated in this study. SNOT-22 from all participants were collected blindly prior to diagnosis. Participants were then categorized in 5 groups according to their outcome: control, medical rhinologic condition, sinus surgery, functional nose surgery. SNOT-22 items relevant to each group were determined by multinomial logistic regression. Results: Control subjects showed the lowest SNOT-22 scores for all items. Medical rhinologic patients had lower scores than surgical patients. Patients requiring sinus surgery and those listed for nose surgery exhibited a specific pattern of SNOT-22 score. Most relevant items were #1 need to blow nose, #5 post-nasal discharge, #6 thick nasal discharge, #10 facial pain and #21 sense of smell. Conclusions: Distinct SNOT-22 patterns were correlated to subjects outcome. SNOT-22 was able to differentiate patients from controls, to score severity, and could further provide an accurate description of pathology. Baseline SNOT-22 could localize pathology in the sinus or in the nose and predict the need for surgical treatment. [less ▲]

Introduction and aim: Acute ENT coverage is available out-of-hours in most hospitals. However, increasing pressure to reduce healthcare cost threatens this service provision round the clock. Our goal was to audit the emergency ENT activity in our institution over a one-month period Material and methods: a prospective audit for all ENT referrals from the emergency department was carried out from May 1st to May 31th 2017. Descriptive statistics were produced for age, sex, origin, time of arrival, diagnosis and patient outcome. Results: a total of 190 patients (109 men and 81 women) were referred to the ENT emergency service over the study period (mean 6.1 case per day). Mean age was 47.9 (±23.6)year (range 1-95). Most patients were ambulatory (75.8%) and came from the area. Most admissions occurred during normal working hours (76.4%) and 62.0% patients came by self reference. The mean complaint duration before admission was 7.6 (±13.7) days (range 0-92 days). One third (33.2% patients) required ambulatory treatment. A quarter (24.7% patients) underwent a minor ENT procedure. Eighteen (9.5%) patients required admission to the ward (mostly for intravenous antibiotic). Eight patients (4.2%) required surgical treatment. There was no difference in the severity of diagnosis or management between patients referred by a physician (GP of specialist) and patients presenting spontaneously. At 30 days, 3 (1.6%) patients died (one of ENT cancer, two of unrelated cause), 106 (55.8%) benefited from an ENT follow’up, 65 (34.2%) were referred to another physician (GP or specialist), 16 (8.4%) were lost to follow’up. Conclusions: The workload suggests that emergency ENT activity is justified in our hospital. Restricting emergency ENT cover to patients referred by a GP or another physician would not allow for a better patient selection. [less ▲]

Introduction Rupture of the internal carotid artery (Carotid blowout syndrome) is a rare complication of irradiated nasopharyngeal tumor. We report three cases nasopharyngeal tumors treated with radiotherapy complicated with bleeding of the internal carotid artery presenting as a massive epistaxis. Case Series The first case presented a few episodes of small nose bleeding before a massive one. Internal carotid embolisation was performed to stop the bleeding. Unfortunately, few month later, he presented a meningitis related to skull base osteoradionecrosis and died from sceptic shock. The second case was transferred to our hospital with severe repetitive epistaxis that had been occurring for hours. No endovascular treatment was possible in his case and he died in intensive care unitthe dayof his admission. The thrid case presented one massive epistaxis which stopped without any treatment or compression. A spontaneous occlusion of his internal carotid artery occured without any neurological defects. He recently benefited from a nasopharyngeal muscle flap for the coverage of the carotid artery. These three patients all presented with a history of nasopharyngeal tumor handled by radiotherapy. Pathogenesis, treatment, and outcome are discussed on the light of a comprehensive literature review. Conclusions Carotid blowout syndrome secondary to radiation therapy is rare but life-threatening. Re-irradiation and skull base osteoradionecrosis are strong predisposing factors. [less ▲]

The popularity of upper airway imaging methods is largely determined by their contribution to the success of predictive models for alternative therapeutic treatment to CPAP, in OSA. If there is still not enough evidence to date that they can improve the outcome of snoring and sleep apnea surgery, it is clear that considerable progress can be expected in the coming years thanks to technological and digital advancements. The cephalometric analysis will certainly benefit from the 3-dimensional analytical capacity of tissue densities provided by Cone Beam tomography. Videoendoscopy could be largely improved by endoscopic long-range optical coherence tomography. At last, novel imaging techniques using computer methods for the prediction of the upper airway will also be of considerable help in decision making in patients with sleep-disordered breathing.
