Writing in the European Annals of Otorhinolaryngology Head & Neck Diseases. Dos and Don'ts!

Too many articles are still rejected by scientific medical journals due to lack of preparation of the manuscript and of knowledge of the modern editorial rules that govern scientific medical writing. Therefore, the editorial board of the European Annals of Otorhinolaryngology Heads & Neck Diseases summarized studies published by its members since 2020 in the columns of the scientific journal of the French Society of Otorhinolaryngology and the International Francophone Society of Otorhinolaryngology and data from the PubMed indexed literature dedicated to scientific medical writing in otolaryngology in the 21st century. The authors hope that this review, in the form of a list of "Dos and Don'ts", will provide authors with a practical guide facilitating publication of rigorous, reproducible and transparent scientific studies, in accordance with the movement toward better science that society as a whole has been fighting for since the beginning of this century.

Cytopathological analysis of salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications for fine-needle cytology and the modalities of frozen section pathological analysis in the management of salivary gland cancer. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group according to the formal consensus method. RESULTS: Fine-needle cytology is recommended as part of the diagnostic work-up for a major salivary gland tumor suspicious for malignancy. Fine-needle cytology should be performed after MRI to avoid artifacts. Frozen section analysis is recommended to confirm the malignant nature of the tumor, to adapt the extent of resection and to indicate neck dissection. Whenever possible, the entire tumor and adjacent salivary or periglandular tissue should be sent for frozen section analysis. CONCLUSION: Fine-needle cytology and frozen section analysis play an essential role in the management of salivary gland cancers.

Diagnostic imaging of salivary gland cancers: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To define the indications for each imaging modality in the screening, characterization, extension and follow-up of salivary gland tumors. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: If a swelling of a salivary gland is palpable for 3 weeks, an ultrasound scan is recommended to confirm a tumoral lesion and rule out differential diagnoses. For a salivary gland tumor, MRI is recommended with diffusion-weighted and dynamic contrast-enhanced techniques. In the case of histologically proven malignancy or a highly suspicious lesion, a CT scan of the neck and chest is recommended to assess the tumor, lymph nodes and metastases. FDG-PET is not currently recommended in routine clinical practice for initial diagnosis, assessment of extension, evaluation of response to treatment, staging of recurrence, or follow-up of salivary gland tumors. CONCLUSION: Assessing salivary tumors is based on MRI. Extension assessment is based on neck and chest CT.

Laryngeal graft after total laryngectomy in humans: A SWiM analysis.

Evaluation of the results of laryngeal transplantation (LT) in humans. Analysis of 3 bibliographic databases with the keywords "larynx, transplantation, autograft". In total, 626 abstracts were read and 25 articles selected. The main objective was to analyze the characteristics of laryngeal transplant patients. The accessory objectives comprised analysis of operative technique, immunosuppressive treatment and results. Four articles were selected for analysis. Two patients were transplanted after total laryngectomy for laryngeal carcinoma and 2 after laryngeal trauma. Three of the 4 patients had true transplantation with arterial, venous and neural microanastomosis. Two patients were decannulated and the tracheostomy tube was maintained in the other 2. Three of the 4 patients had good-quality phonation and could feed without a gastric tube. One patient died of carcinoma progression and 1 patient had to be explanted 14 years after transplantation. The number of LTs reported is too small for scientific determination of the place of this intervention in laryngology. The published results could, at first sight, suggest that the future of LT is uncertain. However, several elements, also suggest that otolaryngologists should continue to take an interest in this technique.

Surgery of major salivary gland cancers: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the role of surgery of the primary tumor site in the management of primary major salivary gland cancer. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group, which drafted a non-systematic narrative review of the literature published on Medline, and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Treatment of salivary gland tumor is mainly surgical. The gold standard for parotid cancer is a total parotidectomy, to obtain clear margins and remove all intraparotid lymph nodes. For low-grade tumors, partial parotidectomy with wide excision of the tumor is acceptable in the case of postoperative diagnosis on definitive histology. In the event of positive margins on definitive analysis, revision surgery should be assessed for feasibility, and performed if possible. CONCLUSION: Treatment of primary major salivary gland cancer is based on surgery with clear resection margins, as far away as possible from the tumor. The type of surgery depends on tumor location, pathologic type and extension.

Systemic therapies for salivary gland carcinoma (excluding adenoid cystic carcinoma): REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the therapeutic indications for systemic medical treatment in the management of salivary gland carcinoma (excluding adenoid cystic carcinoma) according to the clinical situation. MATERIALS AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Salivary gland carcinoma is rare and there is currently insufficient evidence to indicate chemotherapy at the localized stage. At the metastatic stage, initial management can be based on a phase of monitoring for indolent disease. Some histological subtypes (salivary duct carcinoma and adenocarcinoma) are more aggressive and require systemic treatment from the outset. To guide systemic treatment, it is recommended to perform immunohistochemistry and molecular biology analyses (overexpression of HER2 and androgen receptors, NTRK fusion, next-generation sequencing). CONCLUSION: Salivary gland carcinoma is a rare tumor for which there are currently few effective medical treatments. It is therefore recommended to include patients in clinical trials.

Surgery of sublingual and minor salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications and modalities for resection in the management of primary sublingual and minor salivary gland cancer, and the specific features of each primary location. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Histological evidence (submucosal biopsy) is recommended before surgical treatment of minor salivary gland carcinoma. Surgical treatment is recommended, with optimal oncologic margins, adapted to anatomical factors, histologic type and grade and functional consequences, with reconstruction if necessary. CONCLUSION: Treatment of primary minor salivary and sublingual gland cancer is surgical, with wide resection margins. The modalities of resection and reconstruction are highly dependent on tumor location, extension and histologic type.

Systemic therapies for salivary gland cancer: Adenoid cystic carcinoma. REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the therapeutic indications for systemic medical treatment in the management of adenoid cystic carcinoma (ACC) according to the clinical situation. MATERIALS AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group, which drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: ACCs are rare tumors and there is currently insufficient evidence to indicate chemotherapy at the localized stage. At the metastatic stage, progression is often slow. In case of oligometastatic ACC, local treatment should be discussed. The most often indolent nature of polymetastatic ACC can allow management by active surveillance. Molecular screening is recommended, for abnormalities potentially accessible to targeted therapy. CONCLUSION: ACCs are rare tumors for which there are currently few effective medical treatments. It is therefore recommended to include patients in clinical trials.

Lymph node surgery for salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications for neck dissection in the management of parotid, submandibular or minor salivary gland cancers depending on the clinical situation: i.e., clinical lymph node involvement (cN+) or not (cN0); low or high risk of occult nodal metastasis; diagnosis of malignancy before, during or after surgery. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group which drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group according to the formal consensus method. RESULTS: In cN+ salivary gland cancer, ipsilateral neck dissection is recommended. In cN0 salivary gland cancer, ipsilateral neck dissection is recommended, except for tumors at low risk of occult nodal metastasis. If definitive pathology reveals a high risk of occult nodal involvement, additional neck treatment is recommended: ipsilateral neck dissection or elective nodal irradiation. CONCLUSION: The rate of occult lymph node involvement, and therefore the indication for elective neck dissection, depends primarily on the pathologic grade of the salivary gland cancer.

Post-treatment monitoring of salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the frequency and modality of post-treatment monitoring of primary salivary gland cancer. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Clinical monitoring should be adapted to the risk of recurrence: initially every 3 months and progressively spaced out, becoming annual after 5 years. Post-treatment head and neck and chest imaging is recommended at 3 months. Local and regional monitoring can then be carried out yearly or twice yearly with contrast-enhanced head and neck imaging. An annual chest CT scan is recommended for high-grade tumors. For lesions at high risk of late recurrence, very prolonged annual surveillance (up to 15 years) is recommended, including screening for pulmonary metastases. CONCLUSION: Given the wide range of malignant salivary gland tumors, the modalities and frequency of post-treatment monitoring must be adapted to the expected course of the disease.

Radiotherapy for salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications for radiotherapy in salivary gland cancer and to specify the modalities and target radiation volumes. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group which drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Postoperatively, radiotherapy to the primary tumor site±to the lymph nodes is indicated if one or more of the following adverse histoprognostic factors are present (risk>10% of locoregional recurrence): T3-T4 category, lymph node invasion, extraglandular invasion, close or positive surgical margins, high tumor grade, perineural invasion, vascular emboli, and/or bone invasion. Intensity-modulated radiation therapy (IMRT) is the gold standard. For unresectable cancers or inoperable patients, carbon ion hadrontherapy may be considered. CONCLUSION: Radiotherapy in salivary gland cancer is indicated in postoperative situations in case of adverse histoprognostic factors and for inoperable tumors.

Carl Gussenbauer and the first artificial larynx after total laryngectomy.

The aim of this historical vignette is to delve into the description and use of the first artificial larynx, developed by Carl Gussenbauer, and used after Theodor Billroth's first total laryngectomy, performed on December 31, 1873.

Surgical approaches for pleomorphic adenoma of the parapharyngeal space.

OBJECTIVE: This study aimed to analyse the outcomes of surgery for pleomorphic adenoma of the parapharyngeal space in relation to the surgical approach. METHOD: This was a single-centre retrospective data analysis conducted from January 2008 to December 2020 on all patients who underwent operation for pleomorphic adenoma originating from the parapharyngeal space. RESULTS: Twenty-one patients with a mean age of 52.6 years were included. The transparotid-transcervical approach was the most common (52.4 per cent, n = 11) surgical approach, followed by transoral robotic surgery (28.6 per cent, n = 6) and conventional transoral surgery (19 per cent, n = 4). Post-operative complications included nine cases of transient partial facial nerve palsy and two cases of Frey's syndrome after the transparotid-transcervical approach and 2 cases of transient trismus and 1 pharyngeal wound dehiscence in the conventional transoral approach group. Complete macroscopic excision was always achieved, and no recurrence occurred during follow up. CONCLUSION: These three approaches can provide adequate tumour visualisation, a high rate of clear excisional margins and an acceptable morbidity.

Keys for successful publication in Eur Ann Otorhinolaryngol Head Neck Dis: A STROBE analysis of peer reviews of articles submitted in 2020-2021.

OBJECTIVE: To evaluate reviewing and editorial decision for articles submitted to the European Annals of Otorhinolaryngology Head & Neck Diseases. MATERIALS AND METHODS: A retrospective analysis was made of reviewers' comments on 1,133 scientific articles (700 original articles, 96 literature reviews, and 337 case reports), originating from 69 countries, consecutively submitted on-line between January 1st, 2020 and December 31st, 2021. The main objective was to document the acceptance rate and decision time. Accessory objectives were to synthesize the main comments and to screen for correlations between acceptance and the main characteristics of first authors, articles and reviewers' comments. RESULTS: In total, 4.1% of submitted articles were accepted. Median decision time differed significantly (P<0.0001), at 1 month in case of refusal and 4 months in case of acceptance. Reviewers mentioned failure to adhere to the journal's authors' guide, to use the appropriate EQUATOR guidelines and to adopt the recommended P<0.005 significance threshold in 94.8%, 54.2%, and 39.9% of cases, respectively. On multivariate analysis, 3 variables significantly impacted acceptance, which increased from 1.3% to 44.6% (P<0.0001) when an appropriate EQUATOR guideline was used and from 0.3% to 57.4% (P<0.0001) when the significance threshold was set at P<0.005, and decreased from 10.5% to 1.1% (P=0.0001) when the article did not originate from a French-speaking country (member of the Francophonie organization). CONCLUSION: Adhesion to modern scientific medical writing rules increased acceptance rates for articles in the European Annals of Otorhinolaryngology Head & Neck Diseases. Teaching modern scientific medical writing needs to be enhanced in otorhinolaryngology.

Guidelines of the French Society of ENT (SFORL): Drug-induced sleep endoscopy in adult obstructive sleep apnea syndrome.

OBJECTIVES: To determine the indications, anesthesiological and surgical procedure and interest of drug-induced sleep endoscopy in the treatment of adult obstructive sleep apnea syndrome. DESIGN: A redactional committee of 17 experts was set up. Conflicts of interest were disclosed and followed up throughout the process of drawing up the guidelines. The work received no funding from any firm dealing in health products (drugs or devices). The GRADE (Grading of Recommendations Assessment, Development and Evaluation) method was applied to assess the quality of the data on which the guidelines were founded. It was stressed that strong recommendations should not be made on the basis of poor-quality or insufficient data. METHODS: The committee studied 29 questions on 5 topics: indications and contraindications, anesthetic technique, surgical technique, interpretation and reporting of results, and management guided by results. RESULTS: Expert review and application of the GRADE method led to 30 guidelines: 10 with high level of evidence (Grade 1+ or 1-), 19 with low level (GRADE 2+ or 2-) and 1 expert opinion. CONCLUSION: Experts fully agreed on the strong guidelines formalizing the indications and modalities of drug-induced sleep endoscopy for adult obstructive sleep apnea syndrome.

Radiotherapy of salivary gland tumours.

Primary tumours of the salivary glands account for about 5 to 10% of tumours of the head and neck. These tumours represent a multitude of situations and histologies, where surgery is the mainstay of treatment and radiotherapy is frequently needed for malignant tumours (in case of stage T3-T4, nodal involvement, extraparotid invasion, positive or close resection margins, histological high-grade tumour, lymphovascular or perineural invasion, bone involvement postoperatively, or unresectable tumours). The diagnosis relies on anatomic and functional MRI and ultrasound-guided fine-needle aspiration for the diagnostic of benign or malignant tumors. In addition to patient characteristics, the determination of primary and nodal target volumes depends on tumor extensions and stage, histology and grade. Therefore, radiotherapy of salivary gland tumors requires a certain degree of personalization, which has been codified in the recommendations of the French multidisciplinary network of expertise for rare ENT cancers (Refcor) and may justify a specialised multidisciplinary discussion. Although radiotherapy is usually recommended for malignant tumours only, recurrent pleomorphic adenomas may sometimes require radiotherapy based on multidisciplinary discussion. An update of indications and recommendations for radiotherapy for salivary gland tumours in terms of techniques, doses, target volumes and dose constraints to organs at risk of the French society for radiotherapy and oncology (SFRO) was reported in this article.

Radiotherapy of sinonasal cancers.

We present the update of the recommendations of the French society of radiotherapy and oncology on the indications and the technical methods of carrying out radiotherapy of sinonasal cancers. Sinonasal cancers (nasal fossae and sinus) account for 3 to 5% of all cancers of the head and neck. They include carcinomas, mucosal melanomas, sarcomas and lymphomas. The management of sinonasal cancers is multidisciplinary but less standardized than that of squamous cell carcinomas of the upper aerodigestive tract. As such, patients with sinonasal tumors can benefit from the expertise of the French expertise network for rare ENT cancers (Refcor). Knowledge of sinonasal tumour characteristics (histology, grade, risk of lymph node involvement, molecular characterization, type of surgery) is critical to the determination of target volumes. An update of multidisciplinary indications and recommendations for radiotherapy in terms of techniques, target volumes and radiotherapy fractionation of the French society of radiotherapy and oncology (SFRO) was reported in this manuscript.
