[Cervicofacial nontuberculous mycobacteria in children: Clinical, microbiological and therapeutic features. A retrospective study and literature review]. / Adénites cervico-faciales à mycobactéries atypiques de l'enfant : caractéristiques cliniques, microbiologiques et thérapeutiques. Étude rétrospective et revue de la littérature.

BACKGROUND: Nontuberculous mycobacteria (NTM) is a common cause of lymphadenitis. A rise in incidence has been reported. Our main aim was to describe the clinical features, microbiological aspects and treatment of the disease. METHODS: We conducted a retrospective, monocentric study between January 2008 and December 2017 (University Hospital of Nantes). INCLUSION CRITERIA: age<18 years, 1 positive lymph node specimen with identification of the species in culture, head-and-neck localization. RESULTS: Forty-nine patients were enrolled from 2008 to 2017. Median age was 28 months (range: 6-141 months). Median time to confirmation of diagnosis was 2.1 months (range: 0.7-6 months). The sites encountered were mandibular (45%), cervical (33%), and parotid (16%). The main clinical signs were a tender nodule (70%), purplish nodule (59%) or painless nodule (83%), without fever (88%). The species identified were: Mycobacterium avium (n=26), M. lentiflavum (n=13), M. intracellulare (n=7), M. malmoense (n=2) and M. scrofulaceum (n=1). Antibiotic treatment was frequent (77% of cases). DISCUSSION: This study is the second largest French cohort of NTM lymphadenitis in children with microbiological confirmation. The most frequent presentation was a tender, purplish, and painless mandibular nodule. The predominant species was M. avium. M. lentiflavum, which emerged during our study, does not figure in any European studies before 2014 but appears in the most recent studies. The effects of discontinuation of mandatory BCG immunization in France in NMT is not statistically demonstrable here due to lack of relevant data prior to 2007. CONCLUSION: A possible diagnosis of NTM lymphadenitis should not be overlooked in children presenting painless, purplish, cervicofacial tumefaction.

Transoral robotic surgery for squamous cell carcinomas of the posterior pharyngeal wall.

Posterior pharyngeal wall squamous cell carcinomas (SCCs) are rare and have an associated poor prognosis. Progress in transoral resection techniques, in particular, transoral robotic surgery (TORS), have renewed the role of surgery in their treatment. This article presents the oncological and functional results obtained by the French Group of Head and Neck Robotic Surgery for TORS for posterior pharyngeal wall SCC-curative surgery. This retrospective, multicentre study presents data collected between September 2009 and November 2013 for patients treated with TORS for posterior pharyngeal wall SCCs. Analysis of patient characteristics, tumour and treatment details were completed. Kaplan-Meier analysis was used to calculate overall survival rates and recurrence-free survival rates. Student's t test and Chi2 test were also calculated. 23 patients were included (mean age of 62 years). 12 patients had a prior HNSCC. Ten patients had pT1 cancers. The overall two-year survival rate was 59%, but 89% for pT1 compared to 28% for pT2-T3 (p = 0.01). It was noted that TORS was simple to perform, but generated significant post-operative dysphagia. Two cases of spondylodiscitis were reported as specific post-operative complications of TORS. In conclusion, TORS is a treatment solution for selected posterior pharyngeal wall SCCs. It provides a possible alternative to medical treatment for early pT1 lesions and is often the only remaining curative solution in patients previously treated with radiotherapy. In cases of bulky resection, or when there is a past medical history of radiotherapy, a tissue reconstruction by forearm free-flap may be indicated.

Clinical outcomes of transoral robotic surgery for supraglottic squamous cell carcinoma: experience of a french evaluation cooperative subgroup of gettec.

BACKGROUND: Transoral, minimally invasive, organ preservation surgeries are increasingly used to treat laryngopharyngeal carcinomas to avoid the toxicity associated with combined chemoradiotherapy regimens. This study investigated the efficiency, safety, and functional outcomes of using transoral robotic surgery (TORS) to perform supraglottic laryngectomy (SGL). METHODS: This was a multicenter study using a case series with planned data collection from 2009 to 2012 for patients with supraglottic squamous cell carcinomas (SCC) who underwent SGL using TORS. RESULTS: Eighty-four (84) of 262 patients underwent TORS for supraglottic SCC. Within 24 hours of surgery, 24% of the patients started on an oral diet. The median use of a feeding tube was 8 days for 76% of other patients. Definitive percutaneous gastrostomy feeding was necessary for 9.5% of the patients. 24% of the patients did require a tracheostomy, and the median use was 8 days. One percent (1%) of the patients had a definitive tracheostomy. Aspiration pneumonia was observed in 23% of the patients during the postoperative course, and was responsible for the death of one patient. Postoperative bleeding occurred in 18% of the patients. Based on the pathology results, 51% of the patients received adjuvant radiation therapy. CONCLUSION: TORS for SGL in intermediate stage SCC is a safe procedure with good functional outcomes and fast recovery times. However, adverse events can occur. Consequently, this technique requires good patient selection criteria to reduce the risk of postoperative complications.

[ENT localisation of amyloidosis: 20 patients report].

Background: Amyloidosis is a rare pathology, due to a toxic accumulation of amyloid proteins infiltrating tissues. Published studies have low statistical power. However it seems that ENT localization have favorable prognosis. Management and check up are not well codified. Methods: Bicentric retros­pec­tive study conducted between 1987 and 2015, from patient diagnosed with ENT amyloidosis. The study was performed to the database of the pathology department. People concerned, history, symptoms and diagnostic features were analysed. The immunologic and clinical status, locations, extension check, treatment and prognosis have been evaluated. Results: Twenty patients were evaluated, ten men and ten women, average age was 55.5 year of age. Three patients were afflicted with familial amyloidosis. Main localisation was larynx (80%), main type was immunoglobulinic (AL) (80%). Amyloidosis was mostly localised (90%) and primary form (80%). Dysphonia was the most frequently encountered symptom. Most performed exami­na­tion were local biopsy and creatinine clearance (100%), serum protein electrophoresis (SEP) (89%), myelogram and/or bone marrow aspiration (75%), and trans thoracic echography (TTE) (75%). Surgical removal was performed for 75% of the patients. Global rate of recurrence was 70%, about 4.6 years after diagnosis. In familial forms, overall survival was 66% at ten years. In non-familial forms, overall survival was 100%. Conclusion: ENT amyloidosis are mostly AL, laryngeal, prima­ry and localised. Distant extension check should be managed by internal medicine specialist and associate creati­ni­ne clea­ran­ce, local biopsy, TTE, SEP and myelogram. Head and neck forms treatment is based on surgical removal, familial forms are of poor prognosis.

Evaluation of new bone formation in irradiated areas using association of mesenchymal stem cells and total fresh bone marrow mixed with calcium phosphate scaffold.

The consequences of the treatment of the squamous cell carcinomas of the upper aerodigestive tract (bone removal and external radiation therapy) are constant. Tissue engineering using biphasic calcium phosphate (BCP) and mesenchymal stem cells (MSC) is considered as a promising alternative. We previously demonstrated the efficacy of BCP and total fresh bone marrow (TBM) in regenerating irradiated bone defect. The aim of this study was to know if adding MSC to BCP + TBM mixture could improve the bone formation in irradiated bone defects. Twenty-four Lewis 1A rats received a single dose of 20 Gy to the hind limbs. MSC were sampled from non-irradiated donors and amplified in proliferative, and a part in osteogenic, medium. 3 weeks after, defects were created on femurs and tibias, which were filled with BCP alone, BCP + TBM, BCP + TBM + uncommitted MSC, or BCP + TBM + committed MSC. 3 weeks after, samples were removed and prepared for qualitative and quantitative analysis. The rate of bone ingrowth was significantly higher after implantation of BCP + TBM mixture. The adding of a high concentration of MSC, committed or not, didn't improve the bone regeneration. The association BCP + TBM remains the most efficient material for bone substitution in irradiated areas.

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.

[Karapandzic flap for reconstruction of extensive defects of the lower lip]. / Place du lambeau de Karapandzic pour la reconstruction des pertes de substance étendues de la lèvre inférieure.

OBJECTIVE: To discuss advantages and disadvantages of Karapandzic flap for reconstruction of extensive defects of the lower lip. METHODS: Two clinical observations and a review of the literature are presented. RESULTS: The Karapandzic flap requires only one operating time. The tissue used to reconstruct the lower lip is very close to the resected lip. The functional result is satisfactory, the lips being continent, allowing speech and feeding. The main advantage of this technique is the preservation of the labial sphincter, which is vascularized, mobile and sensitive. The aesthetic result is acceptable. This flap keeps the vermilion, but with rounded commissures that corrects spontaneously. The main disadvantage of this flap is the microstomia, requiring only rarely further surgery. CONCLUSION: The Karapandzic flap is a good option for reconstruction of extensive defects of the lower lip. It recreates the labial sphincter, while maintaining its vascularization and innervation. Functionality is maintained, with an aesthetically acceptable result despite the presence of residual microstomia proportional to the defect.

Voxel-wise analysis: A powerful tool to predict radio-induced toxicity and potentially perform personalised planning in radiotherapy.

Dose - volume histograms have been historically used to study the relationship between the planned radiation dose and healthy tissue damage. However, this approach considers neither spatial information nor heterogenous radiosensitivity within organs at risk, depending on the tissue. Recently, voxel-wise analyses have emerged in the literature as powerful tools to fully exploit three-dimensional information from the planned dose distribution. They allow to identify anatomical subregions of one or several organs in which the irradiation dose is associated with a given toxicity. These methods rely on an accurate anatomical alignment, usually obtained by means of a non-rigid registration. Once the different anatomies are spatially normalised, correlations between the three-dimensional dose and a given toxicity can be explored voxel-wise. Parametric or non-parametric statistical tests can be performed on every voxel to identify the voxels in which the dose is significantly different between patients presenting or not toxicity. Several anatomical subregions associated with genitourinary, gastrointestinal, cardiac, pulmonary or haematological toxicity have already been identified in the literature for prostate, head and neck or thorax irradiation. Voxel-wise analysis appears therefore first particularly interesting to increase toxicity prediction capability by identifying specific subregions in the organs at risk whose irradiation is highly predictive of specific toxicity. The second interest is potentially to decrease the radio-induced toxicity by limiting the dose in the predictive subregions, while not decreasing the dose in the target volume. Limitations of the approach have been pointed out.

Management of the neck in the setting of definitive chemoradiation: is there a consensus? A GETTEC study.

BACKGROUND: The management of the neck remains controversial in the definitive chemoradiation setting of advanced N2-3 head and neck squamous cell carcinoma. Most published data favor omission of neck dissection (ND) after complete response for N2-3 or selective ND for residual disease METHODS: We studied the patterns of care in the French-Belgian Groupe d'Etude des Tumeurs de la Tête Et du Cou (GETTEC) through a questionnaire-based survey. RESULTS: Eighteen percent of institutions never performed up-front ND, 20% rarely, 40% sometimes, 14% often, and 8% systematically. Induction chemotherapy was indicated in 30% of the cases, and most ND were performed either between induction and radiation or after chemoradiation for residual disease. Response to chemoradiation was assessed by computed tomographic scan and positron emission tomography in 72% of cases. Selective ND was more common than radical ND. CONCLUSIONS: Omission of ND based on computed tomographic scan and positron emission tomography-based complete response to chemoradiation is the most common strategy for advanced nodal disease among centers. However, neck management strategies vary among institutions, and some institutions continue advocating systematic ND before irradiation. The new treatment options and the changing epidemiology, namely docetaxel-based induction chemotherapy and human papilloma virus-related head and neck squamous cell carcinoma having better response profiles and prognosis, are adding to the nonconsensual approach. The best therapeutic index in terms of neck management remains to be defined in this evolving context.

[Ethmoidal metastasis revealing lung adenocarcinoma]. / Métastase ethmoïdale révélant un adénocarcinome pulmonaire.

OBJECTIVES: Ethmoidal cancers are rare and are mostly primitive adenocarcinomas. Sinuso-nasal metastases from adenocarcinoma occurring in other localisations are exceptional. We report a case of a patient presenting with an ethmoidal metastasis revealing a pulmonary adenocarcinoma. CASE REPORT: A 57 years-old patient consulted for a right fronto-orbital pain which had appeared 3 weeks prior, associated with a central scotoma of the right eye and a third and fifth cranial nerve palsy. MR-imaging revealed a right ethmoidal tumour invading the orbit. Pathology results were in favour of a metastasis from a secondary adenocarcinoma. The CT-scan disclosed a pulmonary tumour of the right apex with liver and spleen metastasis. CONCLUSION: Ethmoidal metastases are rare and often diagnosed in patients presenting with a previously known tumour. We report the first case of a pulmonary adenocarcinoma revealed by an ethmoidal metastasis. We emphasize the point that in ethmoidal tumours, pathological investigations are important for diagnosis.

[Parapharyngeal tumors: management and postoperative results]. / Tumeurs de l'espace parapharyngé: prise en charge et résultats postopératoires.

OBJECTIVES: Parapharyngeal space tumours are rare and mostly benign, and their access is difficult. The aim of the study was to define the optimal treatment of these tumours. MATERIAL AND METHODS: Clinical retrospective study, with histological, treatment, prognosis analysis of the parapharyngeal space tumours occurred between 1994 and 2012 and the surgical approach considerations. RESULTS: 35 patients were included with a male sex ratio predominance (51.43%, p = ns). The mean age of diagnosis was 49 years. The majority of tumours were benign (75.76%, p < 0.001). 54.5% originated from salivary gland with a majority of pleomorphic adenomas (42.42%). The second most frequent aetiology found was schwannoma (21.21%). 2 patients refused the treatment. Accidentally discovered were frequent (28.57%). In the symptomatic forms, dysphagia dominated (25.71%). Oropharyngeal (20%) and/or cervical (17.14%) mass were rare. A CT scan and a MR imaging were performed in 82.86% and 71.43% of the cases. A fine needle aspiration cytology was achieved in 10 cases with a positive predictive value of 60%. The cervical submandibular trans digastric approach was the most accomplished (40%). Other approaches were also used: Trans oral (25.71%), parotidectomy (14.71%), combined trans oral and cervical or parotidectomy (14.71%) and the cervical approached associated to a mandibulotomy (5.71%). A complementary treatment was proposed in 85.7% of the cases of malignant tumours. Post-operative complications were dominated by Horner's syndrome (n = 3), a temporary facial palsy (n = 5), definitive (n = 1), a velar insufficiency (n = 1), persistent pain (n = 6). CONCLUSIONS: The presence of 25% of malignant tumours and 40% of pleomorphic adenomas require removal of parapharyngeal tumours, even if non symptomatic.

Guidelines of the French Society of Otorhinolaryngology-Head and Neck Surgery (SFORL), part I: Primary treatment of pleomorphic adenoma.

INTRODUCTION: The authors present the guidelines of the French Society of Otorhinolaryngology-Head and Neck Surgery (SFORL) for the diagnosis and treatment of pleomorphic adenoma (PA) of the salivary glands. METHOD: A review of the literature was performed by a multidisciplinary task force. Guidelines were drafted based on the articles retrieved and the workgroup members' individual experience. Guidelines were graded A, B, C or expert opinion by decreasing level of evidence. RESULTS: In clinically suspected salivary gland PA, MRI should be performed, including head and neck lymph node levels. Fine needle aspiration cytology is particularly recommended for tumours difficult to characterise by MRI. Frozen section biopsy should be performed to confirm diagnosis and adapt the surgical procedure in case of intraoperative findings of malignancy. Complete resection of the parotid PA should be performed en bloc, including margins, when feasible according to tumour location, while respecting the facial nerve. Enucleation (resection only in contact with the tumour) is not recommended. For the accessory salivary and submandibular glands, complete en bloc resection should be performed.

Statistics in scientific articles published in the European Annals of Otorhinolaryngology Head & Neck Diseases.

OBJECTIVES: To evaluate biostatistics in scientific articles published in the European Annals of Otorhinolaryngology Head & Neck Diseases. MATERIALS AND METHODS: Retrospective analysis of 76 scientific articles published in 2018 and 2019. The main goal was to describe the percentage of articles using biostatistics and to explore for potential associations with the article's main characteristics. Secondary goals were, within the group of articles using statistical tests, to describe the type of statistics used, the assessment of normality in case of comparison of mean values, the p-value threshold for significance, the use of confidence intervals, and power analysis. RESULTS: Statistics were used in 73.7% of articles, without any significant association with main characteristics. Within the group of articles using statistics, the tests used were parametric, non-parametric and not specified in 77.7%, 51.4% and 1.8% of cases, respectively. Normality was checked in 14.2% of article using parametric tests to evaluate mean values. The p-value significance threshold was set at .05, .01, .005 levels and not defined in 60.7%, 1.8%, 1.8% and 35.7% of articles, respectively, while confidence intervals and power analyses were documented in 10.7% and 5.3%, respectively. CONCLUSION: This article underlines the need for better use of statistics in the European Annals of Otorhinolaryngology Head & Neck Diseases, to improve the quality of scientific articles published in the organ of written expression of the French and International French-speaking Societies of Otorhinolaryngology, and to support the ongoing move toward better medical science.

Guidelines of the French Society of Otorhinolaryngology-Head and Neck Surgery (SFORL), part II: Management of recurrent pleomorphic adenoma of the parotid gland.

INTRODUCTION: The authors present the guidelines of the French Society of Otorhinolaryngology-Head and Neck Surgery (SFORL) for the management of recurrent pleomorphic adenoma (RPA) of the parotid gland. METHOD: A review of the literature was performed by a multidisciplinary task force. Guidelines were drafted, based on the articles retrieved and the work group members' individual experience. There were then read and re-edited by an independent reading group. The proposed recommendations were graded A, B or C on decreasing levels of evidence. RESULTS: Complete resection under neuromonitoring is recommended in case of RPA. The risks of progression and malignant transformation, which are higher the younger the patient, have to be taken into consideration. The risk of functional sequelae must be explained to the patient. MRI is recommended ahead of any surgery for parotid RPA, to determine extension and detect subclinical lesions. Radiotherapy should be considered in case of multi-recurrent pleomorphic adenoma after macroscopically complete revision surgery at high risk of new recurrence (microscopic residual disease), in case of RPA after incomplete resection, and in non-operable RPA.

[Retro- and parapharyngeal abscess in children: predictive factors of medical treatment failure]. / Abcès rétro- et parapharyngés de l'enfant: facteurs prédictifs d'échec du traitement médical.

OBJECTIVE: To consider the predictive factors of failure after medical treatment (intravenous antibiotics) first initiated in children with retro- and parapharyngeal abscess, without life-threatening complications. PATIENTS AND METHODS: Retrospective study between 1998 and 2006 of 45 children treated at the Nantes University Hospital for a retro- and parapharyngeal abscess. RESULTS: Median age was 3.8 years. Thirty (66%) patients required surgical management. Significant predictive factors of failure of initial medical therapy were: patients under 3 years of age, symptoms more than 3 days before intravenous antibiotic therapy, leukocyte count higher than 22,000 per millimeter cube, hypodensity diameter greater than 20mm, and abscess demonstrated on CT scan. Previous antibiotic therapy at home was not significantly related to medical treatment failure. Broad-spectrum antibiotic therapy associations did not improve medical outcome. CONCLUSION: The predictive factors of failure after initial medical therapy for retro- and/or parapharyngeal abscess in children are underlined; these factors help determine the clinical approach.

Outpatient management in plastic and reconstructive head and neck surgery in France.

The present review lays out the main principles governing outpatient management in the French health system in 2018, and more specifically in plastic and reconstructive head and neck surgery. The historical regulatory aspects and the changes of the last few years are explained, along with the trends and health authorities' expectations for the years to come. The main limitations to implementing outpatient procedures are the common to all surgical specialities, plastic and reconstructive head and neck surgery being no exception. Apart from purely technical aspects concerning surgical procedure and anesthesia, there are issues concerning institutional approval, the organization and continuity of health care, and the patient's environment. The French General Inspectorate of Social Affairs (IGAS), in its 2012 report on the assessment and pricing of hospital care and medical acts, stated that outpatient surgery was becoming standard practice and conventional admission a fall-back, with the aim of meeting the requirement to provide more care without more expenditure. Outpatient plastic and reconstructive head and neck surgery may be available for most patients, but still presupposes certain conditions.

Peripheral neck nerve tumor: A 73-case study and literature review.

OBJECTIVES: Peripheral neck nerve tumors are rare and mostly benign neoplasms. The exceptional malignant forms are very aggressive, and diagnosis is difficult. The objective of this study was to evaluate diagnostic and therapeutic management and identify possible predictive factors. MATERIAL AND METHODS: A retrospective study was conducted of 73 patients treated for peripheral neck nerve tumor between 1995 and 2015. RESULTS: Mean age was 44years. The main presenting symptom was a cervical mass, isolated or associated with signs related to the affected nerve structure. Diagnosis was suspected by slow progression of a firm mass, featuring T1 hyposignal and T2 hypersignal on magnetic resonance imaging. Surgery was performed in 99% of cases, completed by adjuvant chemotherapy in case of malignant neuroblastic tumor. Type 1 neurofibromatosis and sudden increase in mass with or without associated pain suggested malignant transformation. Age below 10years suggested neuroblastic tumor. CONCLUSION: Neck nerve tumors are very often benign with low degenerative potential. Surgery is the treatment of choice after risk/benefit analysis. However, there is no clearly defined consensus regarding the timing of surgery for these lesions.

Intraoperative bacterial analysis in nasal polyposis: Clinical and functional impact.

BACKGROUND: The impact of Staphylococcus aureus on onset of nasal polyposis has been the focus of numerous studies, but there have been few studies of other germs found in the ethmoid of operated patients or of their impact on post-operative results. MATERIAL AND METHODS: All patients undergoing endoscopic radical ethmoidectomy for nasal polyposis in the teaching hospital of Nantes (France) between 2006 and 2016 had intraoperative ethmoid cavity bacterial sampling. Phenotypic characteristics, pre- and post-operative symptoms and endoscopic findings were analyzed. Mann-Whitney tests and Kruskal-Wallis correlation analysis were used to assess clinical/bacteriological correlations. OBJECTIVES: The main objective was to describe bacterial colonization of patients undergoing surgery for nasal polyposis, and to assess correlations with phenotypic features, functional results and postoperative clinical course. RESULTS: One hundred and seven patients were included. A total of 26% were not infected, 55% mono-infected and 19% multi-infected. In 27.3%, staphylococci were isolated; in 30.5%, isolates were gram-negative bacilli. There were no significant correlations between presence or type of pathogen and symptom profile. CONCLUSION: This study confirmed the high rate of pathogenic bacteria in nasal cavities in case of polyposis, with high frequencies of S. aureus but also of gram-negative bacilli, raising the question of their involvement in the inflammatory reactions underlying the nasal polyposis.
