Background The rapid spread of the coronavirus disease 2019 and the implementation of quarantine in many European countries led to a swift change in health care delivery. Telemedicine was implemented in many otolaryngological departments to ensure the continuous care. The purpose of this study is to report our experience about telemedicine in 86 patients consulting virtually in our departments. Methods A total of 86 patients benefited from telemedicine consultation from April to Mai May 2020. Patients and physicians were invited to fulfill a satisfaction survey over the 3 days after the consultation. Results Patients consulted in the following fields: laryngology, voice and swallowing (N=15; 17.4%), head and neck or plastic surgery (N=34; 39.5%), rhinology (N=31; 36.1%) and otology (N=6; 7.0%). Practitioners estimated that the clinical examination would not have changed the consultation issue in 73.2% of cases. The realization of delayed clinical examination was rapidly necessary in 9.3% of cases and useless in 33.7% of cases. Five percent of patients estimated that the consultation did not bring reliable conclusion. Although the majority of patient (87.7%) would recommend telemedicine consultation to friend/family in the context of pandemic, only 44.6% would accept to replace office- consultation by telemedicine consultation outside the pandemic. Conclusion Telemedicine appears to be an interesting alternative approach in situation of pandemic and lock-down. Because the patient motivation to further participate to telemedicine appears to be conditioned by the context, efforts are still required to understand the patient perception, satisfaction and fears in view of future implementation outside pandemic.

Objective: To investigate the feasibility and the outcomes of transoral laser CO2 microsurgery (TLM) for resection of early-stage squamous cell carcinoma (SCC) of the vocal folds through several additional surgical procedures and tips improving the glottic exposure. Methods: Retrospective chart review of patients treated by TLM cordectomy in a single European University Hospital for early-stage vocal fold SCCs (Tis, T1a, T1b, and T2). The following TLM outcomes were studied regarding the tumor size (Tis and T1a vs T1b and T2) and the margin status (negative vs positive/suspicious): patient position; type of laryngoscope; requirement to external counter pressure; resection of supraglottic structures (eg, ventricular band, epiglottic petiole, and suprahyoid epiglottis); pre- and postoperative complications; overall survival; disease-specific survival (DSS); and disease-free survival (DFS). Results: A total of 148 patients were included. The TLM was realized in 95.3% of cases. External counter pressure, partial, or total vestibulectomy were necessary in 65.9%, 57.4%, and 4.2% of cases, respectively. A resection of the epiglottic petiole was required in 24.8% of cases. The realization of both epiglottis petiole resection and vestibulectomies were significantly higher in patients with T2 and T1b SCCs compared to those with T1a and Tis SCCs ( P = .01). Different procedure tips were described for improving the laryngeal exposition. The 5-year laryngeal preservation rate, DSS, and DFS were significantly better in patients without SCC involvement of the anterior commissure, and did not vary according to the margin status. The laryngeal exposure difficulties did not impact the margin status. Conclusion: The exposure of glottis is possible in 95% of cases of early-stage vocal cord SCC but requires the use of several additional surgical procedures, especially for anterior commissure SCCs. The SCC involvement of the vocal fold anterior commissure is associated with lower DSS, DFS, and laryngeal preservation rate.

International audience; Introduction: To explore the prevalence of dysphonia in European patients with mild-to-moderate COVID-19 and the clinical features of dysphonic patients.Methods: The clinical and epidemiological data of 702 patients with mild-to-moderate COVID-19 were collected from 19 European Hospitals. The following data were extracted: age, sex, ethnicity, tobacco consumption, comorbidities, general, and otolaryngological symptoms. Dysphonia and otolaryngological symptoms were self-assessed through a 4-point scale. The prevalence of dysphonia, as part of the COVID-19 symptoms, was assessed. The outcomes were compared between dysphonic and nondysphonic patients. The association between dysphonia severity and outcomes was studied through Bayesian analysis.Results: A total of 188 patients were dysphonic, accounting for 26.8% of cases. Females developed more frequently dysphonia than males (P = 0.022). The proportion of smokers was significantly higher in the dysphonic group (P = 0.042). The prevalence of the following symptoms was higher in dysphonic patients compared with nondysphonic patients: cough, chest pain, sticky sputum, arthralgia, diarrhea, headache, fatigue, nausea, and vomiting. The severity of dyspnea, dysphagia, ear pain, face pain, throat pain, and nasal obstruction was higher in dysphonic group compared with nondysphonic group. There were significant associations between the severity of dysphonia, dysphagia, and cough.Conclusion: Dysphonia may be encountered in a quarter of patients with mild-to-moderate COVID-19 and should be considered as a symptom list of the infection. Dysphonic COVID-19 patients are more symptomatic than nondysphonic individuals. Future studies are needed to investigate the relevance of dysphonia in the COVID-19 clinical presentation.

Summary Objective To investigate oncological, surgical and functional outcomes of transoral robotic surgery cordectomy (TORS-Co). Methods A retrospective chart review of patients benefiting from TORS-Co for a cT1a vocal fold squamous cell carcinoma was conducted at a single academic medical center. TORS-Co was performed through da Vinci robot. The following outcomes were studied: preoperative and operative exposures; feasibility; conversion rate; average robotic set-up and operative times; margin status; postoperative complications; tracheotomy and feeding tube requirement. Results The medical record data of 12 patients were collected. Among them, two patients were excluded because the laryngeal exposition was not adequate. From the 10 included patients, TORS-Co was not performed in three patients. The tumor was not exposable regarding anatomical conditions in two patients, while the size of the robot arms did not allow an adequate exposure in another patient. TORS-Co was performed in the remaining seven patients without transient tracheotomy or feeding tube. The mean estimated blood loss was 20 mL. The average robotic set-up and operative times were 26 minutes and 30 minutes, respectively. The mean hospital stay was 2 days. The margins were not analyzable regarding the use of the monopolar. Two patients reported postoperative complications, while five required class 2 analgesics for postoperative pain. The mean duration of follow-up was 44 months (minimum duration of 36 months). One recurrence occurred 2 years post-surgery. The recurrence was successfully treated by transoral laser CO2 microsurgery. Conclusion The exposure of the laryngeal surgical field is the primary limitation of TORS-Co. TORS-Co may not report better oncological and functional outcomes than transoral laser CO2 microsurgery, which remains the gold standard surgical approach for early glottic squamous cell carcinoma.

International audience; We investigated safety and efficacy of transoral robotic surgery (TORS) for base of tongue (BOT) reduction in obstructive sleep apnea syndrome (OSAS) patients. PubMed, Cochrane Library, and Scopus were searched. A meta-analysis was performed. Random effects models were used. Thirty-one cohorts met our criteria (1693 patients). The analysis was based mostly on retrospective studies. The summary estimate of the reduction of Apnea–Hypoxia Index (AHI) was 24.25 abnormal events per hour (95% CI: 21.69–26.81) and reduction of Epworth Sleepiness Scale (ESS) was 7.92 (95% CI: 6.50–9.34). The summary estimate of increase in lowest O2 saturation was 6.04% (95% CI: 3.05–9.03). The success rate of TORS BOT reduction, either alone or combined with other procedures, was 69% (95% CI: 64–79). The majority of studies reported low level of evidence but suggested that TORS BOT reduction may be a safe procedure associated with improvement of AHI, ESS, and lowest O2 saturation.

• COVID-19 patients with total loss of smell have more olfactory bulb abnormalities at the magnetic resonance imaging than patients without loss of smell. • The olfactory bulb MRI abnormalities may be objectified through a signal intensity ratio measurement that is calculated between the average signals of the olfactory bulb and the frontal white matter. • The loss of smell is probably due to olfactory bulb inflammation related to virus spread.

Objective: To investigate prevalence and epidemiological and clinical factors associated with OD and GD in COVID-19 patients according to the disease severity. Study design: Cross-sectional study. Methods: A total of 2,579 patients with a positive diagnosis of COVID-19 were identified between March 22 and June 3, 2020 from 18 European hospitals. Epidemiological and clinical data were extracted. Otolaryngological symptoms, including OD and GD were collected through patient-reported outcome questionnaire and sniffin-sticks tests were carried out in a subset of patients. Results: A total of 2,579 patients were included, including 2,166 mild (84.0%), 144 moderate (5.6%) and 269 severe-to-critical (10.4%) patients. Mild patients presented an otolaryngological picture of the disease with OD, GD, nasal obstruction, rhinorrhea and sore throat as the most prevalent symptoms. The prevalence of subjective OD, GD were 73.7 and 46.8% and decrease with the severity of the disease. Females had higher prevalence of subjective OD and GD compared with males. Diabetes was associated with a higher risk to develop GD. Among the subset of patients who benefited from psychophysical olfactory evaluations, there were 75 anosmic, 43 hyposmic and 113 normosmic patients. The prevalence of anosmia significantly decreased with the severity of the disease. Anosmia or hyposmia were not associated with any nasal disorder, according to SNOT-22. Conclusion: OD and GD are more prevalent in patients with mild COVID-19 compared with individuals with moderate, severe or critical diseases. Females might have a higher risk of developing OD and GD compared with males.

Objectives: We investigated the prognostic value of pre-treatment hematological parameters in patients with p16-positive oropharyngeal squamous-cell carcinoma (OPSCC). Material and methods: Neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), and hemoglobin concentration measurement (Hb), were collected on day one of treatment. Endpoints were overall survival (OS) and progression-free survival (PFS). All patients were planned to receive concurrent chemoradiation. Staging were reviewed according to the recent AJCC 8th edition. Results: We included 167 patients in this study. In multivariate analyses, a smoking history > 30 packyears was associated with decreased OS (p = 0.009; HR, 3.4827) and PFS (p = 0.042; HR, 2.421); Hb < 12 g/dL was associated with impaired OS (p = 0.007; HR, 6.527) and PFS (p = 0.014; HR, 4.092); an NLR > 5 before treatment was associated with decreased OS (p = 0.042; HR, 2.945). Hemoglobin concentration and the NLR were not correlated (p = 0.577), nor anemia and an NLR > 5 (p = 0.167). Patients with an NLR > 5 had a significantly higher rate of disease recurrence (30.8% vs. 8.4%, p = 0.0299, RR = 3.922, 95% CI 1.351–11.386). Discussion: We found hemoglobin level and the NLR to be independent prognostic factors in p16-positive OPSCC patients. This approach is to be considered for further clinical investigations, and its significance in treatment decision-making should be further explored.

Objective To evaluate the oncological, functional and voice rehabilitation outcomes of transoral robotic surgery for total laryngectomy (TORS-TL). Methods A retrospective chart review of patients treated by TORS-TL was conducted at a single academic medical center. The following outcomes were studied: indication; average robotic set-up and operative times; mean estimated blood loss; postoperative complications; re-feeding features; mean hospital stay; need of adjuvant therapy and voice rehabilitation type. Results TORS-TL was performed in 10 patients for the following indications: nonfunctional larynx (N = 2); low-grade cricoid chondrosarcoma (N = 3) and recurrent laryngeal cancer after (chemo) radiation (N = 5). Two patients were excluded because the larynx was not exposable. Average robotic set-up and operative times were 20 and 278 min, respectively. The mean estimated blood loss was 50 mL. The mean hospital stay was 13.9 days (8–28 days). There was no local recurrence in patients operated for cancer recurrence (N = 5) 5 years after the surgery. Distant metastases occurred in one patient. A patient with laryngeal chondrosarcoma experienced local failure 3 years after TORS-TL. The voice rehabilitation consisted of esophageal voice (N = 2) and tracheoesophageal prosthesis (Provox®, N = 8). The main reasons for prosthesis replacement were transprosthetic (79%) and periprosthetic leaks (21%). The median lifespan of prostheses was 81 days. Conclusion TORS-TL may be a safe and effective surgical approach for selected surgical indications. Future controlled studies are needed to determine additional indications and limitations of this procedure.

International audience; Objective: To investigate the occurrence of olfactory and gustatory dysfunctions in patients with laboratory-confirmed COVID-19 infection. Methods: Patients with laboratory-confirmed COVID-19 infection were recruited from 12 European hospitals. The following epidemiological and clinical outcomes have been studied: age, sex, ethnicity, comorbidities, and general and otolaryngological symptoms. Patients completed olfactory and gustatory questionnaires based on the smell and taste component of the National Health and Nutrition Examination Survey, and the short version of the Questionnaire of Olfactory Disorders-Negative Statements (sQOD-NS). Results: A total of 417 mild-to-moderate COVID-19 patients completed the study (263 females). The most prevalent general symptoms consisted of cough, myalgia, and loss of appetite. Face pain and nasal obstruction were the most disease-related otolaryngological symptoms. 85.6% and 88.0% of patients reported olfactory and gustatory dysfunctions, respectively. There was a significant association between both disorders (p < 0.001). Olfactory dysfunction (OD) appeared before the other symptoms in 11.8% of cases. The sQO-NS scores were significantly lower in patients with anosmia compared with normosmic or hyposmic individuals (p = 0.001). Among the 18.2% of patients without nasal obstruction or rhinorrhea, 79.7% were hyposmic or anosmic. The early olfactory recovery rate was 44.0%. Females were significantly more affected by olfactory and gustatory dysfunctions than males (p = 0.001). Conclusion: Olfactory and gustatory disorders are prevalent symptoms in European COVID-19 patients, who may not have nasal symptoms. The sudden anosmia or ageusia need to be recognized by the international scientific community as important symptoms of the COVID-19 infection.

We report the clinical features of 3 patients in France who had parotitis (inflammation of the parotid salivary glands) as a clinical manifestation of confirmed coronavirus disease. Results from magnetic resonance imaging support the occurrence of intraparotid lymphadenitis, leading to a parotitis-like clinical picture.

BACKGROUND We investigated the survival of patients with a p16-positive N3 oropharyngeal squamous cell carcinoma (OPSCC) and the prognostic significance of patient, tumor, and treatment characteristics. METHODS We retrospectively reviewed the data of patients treated at our Cancer Center for a p16-positive N3 OPSCC between 2003 and 2016. End points were overall survival (OS) and progression-free survival (PFS). RESULTS A total of 29 patients were included. The 5-year OS and PFS were 67.5% and 59.1%, respectively. Smoking history above 10 pack-years and the absence of human papillomavirus DNA were associated with worse OS (P = .02 and P = .03, respectively) and PFS (P = .02 and P = .02, respectively). Induction chemotherapy or radical neck dissection were not associated with different treatment outcomes. CONCLUSION Patients with an N3 p16-positive oropharyngeal cancer in our series had a 5-year OS rate of 67.5%. Smoking history and viral DNA were prognostic factors associated with survival.
