Based on a review of the medical literature, the authors document the key technical points and pitfalls in type I thyroplasty with Montgomery® implant, and the main results and indications in unilateral laryngeal immobility.

Union of the European Phoniatricians' position statement on the exit strategy of phoniatric and laryngological services: staying safe and getting back to normal after the peak of coronavirus disease 2019 (issued on 25th May 2020).

BACKGROUND: The following position statement from the Union of the European Phoniatricians, updated on 25th May 2020 (superseding the previous statement issued on 21st April 2020), contains a series of recommendations for phoniatricians and ENT surgeons who provide and/or run voice, swallowing, speech and language, or paediatric audiology services. OBJECTIVES: This material specifically aims to inform clinical practices in countries where clinics and operating theatres are reopening for elective work. It endeavours to present a current European view in relation to common procedures, many of which fall under the aegis of aerosol generating procedures. CONCLUSION: As evidence continues to build, some of the recommended practices will undoubtedly evolve, but it is hoped that the updated position statement will offer clinicians precepts on safe clinical practice.

Voice outcome indicators for unilateral vocal fold paralysis surgery: A survey among surgeons.

INTRODUCTION: Standardization of voice outcomes indicators (VOIs) is an important issue when it comes to evaluating and comparing surgical treatments for Unilateral Vocal Fold Paralysis (UVFP). In a recent review, 11 VOIs were found to represent 80% of the VOIs cited in the literature. A survey was launched among the European laryngologists to acquire surgeons' opinions on the above mentioned preselected VOIs. MATERIAL AND METHOD: The electronic survey took place between November and December 2016. Three general questions were asked about surgeon's practice setting(s) and experience. The eleven next questions concerned (a) surgeon's VOIs preference and (b) their estimates of post-operative target values, they would consider being satisfactory. RESULTS: The response rate was 16% (50 surveys). The majority of responders worked in tertiary hospitals (50%), had 15 years of experience with UVFP and performed on average 20 UVFP related procedures a year. The VOIs that were favored by the responding surgeons were, in decreasing order of importance, Voice handicap Index (VHI-30), Maximum Phonation Time (MPT), GRBAS-I, Mean Airflow Rate (MeAF), Jitter and Shimmer. There was an excellent consensus on post-operative VOI target values between survey's results and the literature data, except for three VOIs that showed somewhat divergent tendencies (absolute VHI-30, Jitter and Shimmer). CONCLUSIONS: Three VOIs are favored by surgeons: VHI-30, MPT and GRBAS-I. Jitter and Shimmer, although very frequently reported and statistically valid in the literature, come last concerning surgeon's choice as VOI for UVFP treatment assessment.

Very long-term Voice Handicap Index Voice Outcomes after Montgomery Thyroplasty: A cross-sectional study.

OBJECTIVE: The aim of this multicentric cross-sectional study was to examine the permanency of Montgomery thyroplasty (MTIS) results from a patient's perspective. DESIGN: The study consisted of collecting Voice Handicap Index (VHI-30) questionnaires from patients who had previously been operated with MTIS between 2 and 12 years before. Very long-term (>2 years) postoperative data were compared with the previously acquired preoperative and early postoperative VHI results. Influence of factors such as age, gender, size/side of the prosthesis and length of the follow-up were also analysed. SETTING: Multicentric study involving three tertiary European voice centres. PARTICIPANTS: Forty-nine unilateral vocal fold paralysis (UVFP) patients, treated by MTIS, were included in the study. MAIN OUTCOME MEASURES: The Voice Handicap Index-30 score. RESULTS & CONCLUSIONS: The median VHI was significantly different over time-points (Friedman's test P < .001), with a significant difference between preoperative and early postoperative time-points (median VHI: 70 vs 21, respectively; P < .001) and between preoperative and very long-term postoperative time-points (median VHI: 70 vs 16, respectively; P < .001). The median VHI did not differ for the early and very long-term postoperative time-points (median VHI: 21 vs 16; P = .470). Age differences, gender differences and size/side differences of the prostheses, centres where surgery took place and length of the follow-up showed no significant influence. Medialisation thyroplasty (MT) overall and MTIS, in particular, should be considered as a possible standard of care for UVFP when permanency of voice results is sought.

International consensus (ICON) on basic voice assessment for unilateral vocal fold paralysis.

There is a growing need for evaluation tools allowing the quantification of the outcome after voice surgeries. Since the end of the 1990s, multiple unfruitful attempts have been made to reach a consensus, including the Dejonckere protocol for the European Laryngological Society in 2001. This suggested to perform objective and quantifiable measures in the following domains: perception, acoustic, aerodynamic, self-evaluation by the patient and videolaryngostroboscopy. But in a PubMed® search with the keywords "Voice Assessment" and "Voice Outcome" since 2001 retrieving 452 articles, only 33 of them were using methods taking into account the first four dimensions proposed by Dejonckere. To elaborate a new and simpler protocol, we chose to focus on unilateral vocal fold paralyses (UVFP), which represents a homogeneous disease in terms of physiology. This protocol was elaborated on the basis of a review of the literature and of the database and experience of the IFOS panel members. In summary, our group recommends the use and implementation of the ELS "basic protocol" with some minor modifications. Voice audio recordings are an indispensable prerequisite, and may even have medico-legal implications. We recommend the systematic use of the Voice Handicap Index (VHI). Perceptual analysis must be performed by using Hirano's GRB scale and voice breathiness has to be prioritized. Currently, acoustic analysis remains optional given the lack of data to support clinical usefulness. Aerodynamic studies should include at a minimum an evaluation of the Maximum Phonation Time, calculated in seconds following multiple trials in order to obtain a recording representing the patient's best possible glottis closure.

International consensus (ICON) on assessment of oropharyngeal dysphagia.

OBJECTIVE: To present international recommendations regarding the proper evaluation of oropharyngeal dysphagia (OD), both objectively and subjectively (self-evaluation). METHODS: Following a thorough review of the literature, 5 experts in the field from 4 different continents answered separately a questionnaire regarding the work-up of OD. Individual answers were presented and discussed during the world ENT conference that was held in Paris in June 2017. This article will present the recommendations issued from that meeting. RESULTS: For the initial objective assessment of OD, it is recommended to perform either a functional endoscopic evaluation of swallowing (FEES) or a videofluoroscopic swallowing study (VFSS). FEES is the more popular investigation given its increased ease of use and accessibility. When evaluating for the presence of aspiration during the objective evaluation of OD, it is recommended to perform either a FEES or a VFSS. In this case, FEES is the favored investigation given its likely increased sensitivity. In order to highlight the presence of oropharyngeal food residue following the deglutition process, it is recommended to perform either a FEES or a VFSS; FEES likely being the more sensitive investigation while VFSS allows a better quantification of the amount of pharyngeal residue. Is it also recommended to objectify the quality of the deglutition process by means of a score during the objective evaluation of OD. Finally, it is recommended to utilize a self-evaluation questionnaire during research studies exploring the deglutition process.

Voice outcome indicators for unilateral vocal fold paralysis surgery: a review of the literature.

INTRODUCTION: There is no consensus on which voice outcome indicators (VOIs) should be used to compare the merits of the various surgical treatments for unilateral vocal fold paralysis (UVFP). Authors performed a literature review to identify which VOIs are most frequently used and most relevant, in terms of significant change in pre- and post-operative measurements, to assess UVFP surgical treatments. METHOD: A Medline/Pubmed literature review was performed and the most frequently used VOIs were identified using a Pareto diagram. For these most frequently used VOI's, the number of studies that showed a statistically significant change in pre- and post-operative results were compared to the total number of studies found using that same VOI, this portion was expressed in percent. This percentage was defined as the "percentage of significance" and used to assess changes of each VOI. RESULTS: Eleven VOIs were identified using the Pareto analysis. These were, in decreasing order of frequency of citation: maximum phonation time (MPT), jitter, Shimmer, video-stroboscopic examination, noise to harmonic ratio (NHR/HNR), mean air flow (MeAF), fundamental frequency (F0), "Infrequent Perceptional Scales", GRBAS scale, mean subglottic pressure (MSGP). MPT, MeAF, factor G of GRBAS-I, Jitter, shimmer and VHI-30 had respective "percentage of significance" of 90, 86, 85, 74, 68 and 64%, respectively. CONCLUSION: The results indicate that MPT, MeAF and GRBAS-I, represent the top-three most frequently used and the most relevant VOIs in terms of "percentage of significance". VHI-30 showed a relatively low rate of use and low "percentage of significance". The role of Jitter and Shimmer remains unclear. Finally, MSGP and the F0 appear to be less relevant VOIs for the evaluation of UFVP surgical treatments in terms of significant change in pre- and post-operative measurements.

Megaesophagus associated with Myasthenia Gravis: a rare condition in humans.

We present the case of a 79 year-old patient with megaesophagus and aphagia, who required percutaneous endoscopic gastrostomy (PEG) feeding. Megaesophagus was considered the sole cause of aphagia by the referring secondary hospital. Solid state sensor videofluoromanometry (VFM) showed a substantial decrease in manometric values within the hypopharynx along with good relaxation of the upper-esophageal sphincter (UES). This led to electromyography (EMG), which showed features compatible with the diagnosis of Myasthenia Gravis (MG). The diagnosis of MG was confirmed by an intravenous injection of edrophonium chloride, performed under VFM monitoring. The co-existence of MG and megaesophagus rarely occurs in humans; although, most small animals, such as dogs, cats, and rodents, present with megaesophagus as an initial symptom of MG.

Learning curve of medialization thyroplasty using a Montgomery™ implant.

UNLABELLED: Type I thyroplasty--also called medialization thyroplasty (MT)--is considered as an effective treatment for glottic incompetence in general and for abductor vocal fold palsy in particular. In the past there have been some concerns about the experience a laryngeal framework surgeon should have in order achieve an acceptable voice outcome. To assess the learning curve of MT performed using the Montgomery(®) hard silicone implant. A retrospective study involving 36 patients divided into three consecutive groups (1, 2, 3) of 12 MT patients or six consecutive groups (1a, 1b, 2a, 2b, 3a, 3b) of six MT patients. OUTCOME MEASURES: acoustic and aerodynamic outcome improvements (δ) compared to the duration of intervention [operative times (OT)]. Data were analysed by Anova, Kuskal Wallis and χ (2) statistical tests, according to data distributions. OT decreased significantly between groups 1, 2 and 3 with a mean OT of 90.5', 71.5' and 56' (p < 0.001), respectively. Objective δ such as maximum phonation time (MPT) (p 0.376), Estimated Sub-Glottic Pressure (ESPG) (p: 0.675) Shimmer (p: 0.543) and Jitter (p: 0.709) did not show significant improvement. Only the voice handicap index (VHI) δ of group 2 showed significant improvement (p 0.005) compared with the two other groups 1 and 3. Surgeon experience decreases the OT significantly. On the other hand, our study did not show a correlation between surgeon experience and voice outcome measures improvemnts (MPT, ESGP, Shimmer, Jitter).

Impending Carotid Blowout Stabilization Using an LT-D Tube.

Adequate stabilization of a patient presenting with a carotid blowout is one of the most challenging issues an on-call ENT surgeon can be confronted with. Reducing the bleeding and securing the airway are essential before more definitive management. We present the case of a 72-year-old patient with head and neck cancer who arrived at the emergency room with a carotid blowout and who was successfully stabilized using a King LT-D ventilation tube.

Delayed endovascular coil extrusion after embolisation for post-tonsillectomy haemorrhage: case report and literature review.

OBJECTIVE: To report a rare case of delayed endovascular coil extrusion following embolisation of a lingual artery pseudoaneurysm. CASE REPORT: A 23-year-old woman presented with dysphagia and odynophagia 11 months after having experienced massive post-tonsillectomy haemorrhage. At that time, the bleeding had been stopped by embolisation of a lingual artery pseudoaneurysm and the external carotid artery. Clinical examination at admission showed extrusion of the embolisation coils in the lateral lower pharyngeal wall. The coils were removed under general anaesthesia in the presence of an interventional radiologist. The procedure and post-operative period were without complication and no bleeding was observed. The dysphagia and pain disappeared and the subsequent seven-month follow-up period was uneventful. CONCLUSION: Although selective embolisation is a safe and effective treatment for severe post-tonsillectomy haemorrhage, the possibility of delayed coil extrusion should be kept in mind.

Hydroxychloroquine as treatment for inflammatory subglottic stenosis: a second successful case.

Inflammatory sub-glottic stenosis is a life threatening condition that represents a therapeutic challenge. Recently, hydroxychloroquine has been suggested as one efficient medical treatment option. This report describes the second case of successful treatment of inflammatory sub-glottic stenosis using hydroxychloroquine.

Hearing processing and communication abilities development may be influenced by chronic inflammation of the airways in children, especially in case of otitis media and/or adenotonsillar hypertrophy. The present review summarizes the influence of adenotonsillar hypertrophy on speech abilities as well as the consequences of otitis media, with a particular focus on peripheral and central hearing, on the development of language, attention, and memory skills.

What do web sites tell us about quality management in Belgian hospitals?

PURPOSE: Following the "Patient Quality and Safety Contract" launch by the Belgian Federal Authorities, Belgian hospital web sites were scrutinized. The aim of this paper is to assess the presence of some sort of quality management strategy within Belgian Acute Care Hospital digital external communications. DESIGN/METHODOLOGY/APPROACH: Digital communications were assessed using a pre-established grid focusing on direct quality improvement testimonies, like a quality manager presence, a quality committee, a specific strategy, etc. FINDINGS: Two hypotheses explain the poor results: structured quality improvement exists in organizations but senior managers do not feel the need to transparently communicate the subject; and quality improvement does not exist in a sufficiently structured way to allow open communication. PRACTICAL IMPLICATIONS: The proposed Federal Contract should improve both quality initiative quality and frequency as well as transparent communication to healthcare workers and patients. ORIGINALITY/VALUE: The paper underlines the urgent need for Belgian healthcare executives to be aware of structured quality management strategy's importance and to be eager to openly communicate the strategy.

Two cases of isolated unilateral paralysis of hypoglossal nerve after uncomplicated orotracheal intubation.

We report two cases of postoperative unilateral hypoglossal nerve palsy following uncomplicated orotracheal intubation for plastic surgery. Both patients underwent a long procedure and were installed in a non physiological position. These two factors might have played an important role in the mechanism of nerve damage. Furthermore, other etiologies of neurological injury like a difficult airway or anatomical anomalies were not present. The aim of these two case reports is to sensitize the anesthetists to hypoglossal nerve palsy and to highlight a potential clinical problem of positioning during plastic surgery.

Physiologic variables for videofluoromanometric assessment of dysphagia: an exploratory study.

STUDY AIM: To assess the physiological variables among Upper Esophageal Sphincter Nadir (UESN), Hypopharyngeal Peak Pressure (HPP) and Pharyngo-Esophageal Pressure Gradient (PEPG) for Videofluoromanometry (VFM). PATIENTS & METHOD: Exploratory non-randomised prospective study comparing UESN, HPP and PEPG of three cohorts of individuals presumably presenting very distinctive "manometric signatures" based on McConnel's Piston Model of swallowing: 11 non-dysphagic volunteers called the Control Group (CG), 10 dysphagic patients presenting a Myotonic Dystrophy (MD), at various stages of evolution, and 10 patients presenting a CricoPharyngeal Barr (CPB), with no post-swallow pharyngeal residue at a previous Modified Barium Swallow (MBS). VFM tests are performed using solid-state three unidirectional transducers produced by Gaeltec Inc. The simultaneous display storage of the standard fluoroscopic swallow of 10 ml liquid barium with UESN and HPP measurements, continuously recorded on a 3-channel polygraph, is performed using a Kay-Pentax Swallowing Work Station. PEPG calculations are subsequently made. RESULTS: Significant different HPP and PEPG values were observed between the three cohorts. MD patients presented HPP and PEPG below 100 mmHg while CPB patients presented HPP and PEPG above 200 mmHg. The CG presented HPP and PEPG between 100 and 200 mmHg. UESN values revealed no significant difference between the three cohorts. A reading scale is proposed. The aim of the scale is to make a link between HPP or PEPG values and physiopathological (not diagnostic) conditions. Patients presenting an HPP or PEPG below 100 mmHg indicate a High probability of Pharyngeal Propulsion Impairment while patients presenting an HPP or PEPG above 200 mmHg are more likely to have an Increased Flow Resistance with appropriate Propulsion Response. Pros and cons for calculation of the PEPG, representing a possibly unnecessary step, are discussed. CONCLUSIONS: In our study, the use of HPP or PEPG as physiological variables provides quantitative data that allow VFM to discriminate three very distinctive swallowing conditions. Further studies are needed to assess the HPP and PEPG obtained with other manometic devices within the same specific populations for them to be considered as universal physiological variables. Eventually, further investigations should answer the question as to whether the calculation of the PEPG represents any value in comparison with HPP measurement alone.

[Laryngeal sarcoidosis: case report]. / Une sarcoïdose laryngée: cas clinique.

Sarcoidosis is a chronic disease characterized by non-caseating granulomatous inflammation in one or multiple organs. The most commonly involved sites are the lungs and the skin. Involvement of the larynx is rare but significant. We present here a case of biopsy-proven of laryngeal sarcoidosis with favourable evolution without specific treatment.

Carotid stenting for impending carotid blowout: suitable supportive care for head and neck cancer patients?

BACKGROUND: Carotid blowout (CB) represents a dramatic end-of-life situation for palliative head and neck cancer patients, their relatives and caregivers. Recently, endovascular therapy has been proposed for head and neck surgical patients. Preliminary reports showed a better outcome with less morbidity compared to the previous treatment modalities. However, the specific use of such techniques for palliative head and neck cancer patients has not been previously described. METHOD: Retrospective review of two cases of head and neck cancer patients receiving palliative care, presenting with a CB, managed with endovascular stent placement. RESULTS: Bleeding was effectively stopped by the procedure in both cases. Both patients developed a post-procedure thromboembolism, which was immediately treated by appropriate anticoagulation therapy. Neurological symptoms resolved within 24 hours allowing rapid hospital discharge. One patient died at home seven months later. The second patient is alive five months after the procedure. No recurrence of CB occurred in either patient. CONCLUSIONS: Endovascular stent placement for CB allows a rapid arrest of bleeding and permits the use of anticoagulation therapy in order to avoid long-term neurological injury. In our view, carotid stenting should be considered as valid supportive care for palliative head and neck patients presenting with a CB.

Conservation laryngeal surgery for selected pyriform sinus cancer.

AIMS: This study reports the treatment of a cohort of patients with pyriform sinus squamous cell carcinoma, using conservative surgery and radiotherapy. METHODS: Thirty-four patients with pyriform sinus SCC were treated between 1986 and 2001, using partial laryngopharyngectomy with or without complementary radiotherapy. Seventy-six percent had stage III-IV lesions. Quality of life questionnaire and clinical examination were used for evaluation of laryngeal function. RESULTS: Conservation surgery was undertaken. All patients underwent neck dissection. Two thirds of the patients received post-operative radiotherapy. Reconstruction was achieved by local muscular flap in 13 cases, radial forearm free flap in 18 and pectoralis major flap in three. Five-year overall and disease-specific survival rates were 50 and 65%, respectively. Successful laryngeal function preservation with local control was achieved in 80% of the patients. CONCLUSION: Partial laryngopharyngectomy is a suitable treatment for early and selected advanced stage pyriform sinus carcinoma with a good functional and oncologic outcome.
