International audience; BACKGROUND:Head and neck mucosal melanoma (HNMM) is aggressive and rare, with a poor prognosis because of its high metastatic potential. The two main subtypes are sinonasal (sinonasal mucosal melanoma [SNMM]) and oral cavity (oral cavity mucosal melanoma [OCMM]). Consensual therapeutic guidelines considering the primary tumour site and tumour-node-metastasis (TNM) stage are not well established.MATERIAL & METHODS:Patients with HNMM from the prospective national French Rare Head and Neck Cancer Expert Network database between 2000 and 2017 were included. Clinical characteristics, treatment modalities, outcomes and prognostic factors were analysed.RESULTS:In total, 314 patients were included. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 49.4% and 24.7%, respectively, in the surgery group; no long-term survivors were observed when surgery was not feasible. Moreover, even after surgery, a high recurrence rate was reported with a median PFS of 22 months. In multivariate analysis, Union for International Cancer Control (UICC) stage and tumour site correlated with PFS and OS. Postoperative radiotherapy (PORT) improved the PFS but not OS in patients with small (T3) SNMM and OCMM tumours. Nodal involvement was more frequent in patients with OCMM (p < 10-4), although, as in SNMM, it was not a significant prognostic predictor.CONCLUSION:Even early HNMM was associated with poor oncologic outcomes due to distant metastases despite surgical resection with clear margins. Lymph node metastases had no impact on the prognosis, suggesting treatment de-escalation in cervical node management. PORT might be useful for local control.

To determine the clinical, histological, epidemiological and occupational data related to exposure to wood dust in a series of 100 nasal sinus malignant tumors.We conducted a retrospective and descriptive study of cases diagnosed between 1st January 1981 and 31 December 2000, in the Auvergne region of France. Individual, medical, and occupational data were collected from a questionnaire completed by the patient (or the patient's family in case of death) and from the medical documents available.Forty-six cases (46 men), with an average age of 63+/-9.2 years [range, 43-82], had been exposed to occupational wood dust before the diagnosis. Fifty-four cases (30 men, 24 women), with an average age of 64.3+/-8.7 years [range, 40-96], had never been exposed. The average annual incidence increased, either for the total population or for the two subgroups distinguished on the basis of occupational exposure to wood dust. The majority of the patients presented different functional symptoms at the time of the diagnosis. For the 46 patients exposed to wood dust, the tumors were primarily ethmoid adenocarcinomas (92%). For the 54 non-exposed patients, the tumors observed were mainly epidermoid carcinomas (57%), then adenocarcinomas (15%). On the 46 patients exposed to wood dust, 85% were carpenters or cabinetmakers. For the majority of the patients, wood dust exposure started before the age of 20 (average age: 17+/-4.5) and the longest exposure began before 1981. The exposure time to wood dust before diagnosis was in the majority of cases greater than 20 years (mean exposure time: 37 years+/-11.4). Only 15% were exposed at the time of the diagnosis (mean time between the end of the exposure to the diagnosis was 11 years+/-2.8). Of the 54 non-exposed patients, no professional risk factor was evidenced.Epidemiologic data, such as the increasing incidence, and clinical and professional data, such as the occupational exposure to wood dust, were in agreement with the French and European literature. It is still probably too early to appreciate the effectiveness of prevention, established in France since 1980, on nasal sinus tumor incidence.

Report a case of tracheopathia osteoplastica and describe from a literature analysis the main clinical, radiological, and therapeutic features of this rare disease based on literature review.A 74-year-old patient suffering from a nasal polyposis that had been repeatedly operated was admitted for surgery of the frontal sinus. The day of surgery, the difficult intubation required a laryngotracheoscopy, which found a dystrophic trachea, with a sprinkling of whitish nodules, and hard swelling. The pathologic exams of a large biopsy specimen using a rigid bronchoscopy provided the diagnosis of tracheopathia osteoplastic. A complementary workup to search for the etiology was undertaken. The risk and the difficulty of the intubation led to suspending the surgery.The CT scan as well as the histological, bacteriological, and immunological tests showed nothing specific. The etiopathogenic hypothesis was the association of chronic disease of the upper airways such as the ozena or the chronic inflammation of the respiratory tract, an endocrine factor, dermatomyositis, exposure to toxic substances such as silica, or tracheobronchial amyloidosis. The bronchial microbiology test is positive in more than 50% of patients, and often Klebsiella ozaenae or Pseudomonas aeruginosa is found.Tracheopathia osteoplastica is a rare tumor, with unknown etiology and physiopathology. The discovery is most often incidental. Progession is slow and it does not compromise the vital prognosis. The treatment is symptomatic. Few surgical tracheal operations are described in the literature.

Determinate the different prognostic factors of survival in ethmoidal sinus adenocarcinomas (ADK).60 patients with ethmoidal sinus ADK. 59 men and one woman. Average of 62.2 years (41-82). Retrospective study between 1985 and 2005. The following data were analyzed: exposure time to wood dust, disease incidence, primary clinical symptoms and ASA score. Radiological data were recovered by tomodensitometry and magnetic resonance imaging. Histological groups were described. TNM classification according to UICC 2002 and Roux/Brasnu was established on clinical and radiological constatations. Different treatments used were analyzed. Estimate of survival rate and impact of different prognostic factors were based on Kaplan-Meier actuarial method and multivariate analysis.Incidence rate was 2.86 patients a year. Exposure average time to wood dust was 25.6 years (2-44). T3/T4 stages were predominant (66.7%). the survival rate was 46.5% at 5 years. The survival rate was significantly superior respectively in T1 and T2 stages than in T3 and T4 stages, and in T4a than in T4b stages. Extension of the lesion to the sphenoid sinus was revealed as a significant bad prognostic factor. The ASA score and the exposure time to wood dust were not identified as statistically significant prognosis factors.Survival factors of ethmoïd sinus ADK were T stage and the extension of the tumor to the sphenoid sinus. On the results of this study, we consider that extension in sphenoïd sinus could be include in TNM classification of ethmoïd sinus adenocarcinomas.

The purpose of this work was to evaluate the diagnostic strategy and outcome of patients treated for tympanic paraganglioma.Nine patients presented with tympanic paraganglioma were treated in our unit from 1996 to 2003. There were eight women and one man, mean age 65 years. Surgery was performed in all nine patients. This retrospective analysis focused on revealing signs, diagnostic tools, surgical procedure for tumor resection, and short-, mid-, and long-term functional outcome.The surgical procedure was well tolerated by all patients. There were no cases of postoperative mastoiditis. None of the patients experienced postoperative dizziness. Total tumor removal was achieved in seven patients. In one patient, incomplete tumor resection was decided in order to preserve facial motion. All patients but one were relieved from their tinnitus in the early postoperative period. In four patients, preoperative hearing levels were worsened by the surgical procedure, essentially through an alteration of preoperative conductive hearing loss.MRI is highly contributive to the diagnosis of tympanic paraganglioma, which should be evoked in patients with pulsatile tinnitus. Diagnosis should be established as early as possible to lower the postoperative morbidity. While surgery can provide cure and relieve tinnitus, there is a high risk of auditory deterioration.

We describe a case of intraparotid facial nerve schwannoma. About sixty patients with intraparotid tumors have been reported in the literature.A 89-year-old female patient presented with a history of progressive facial palsy and a left intraparotid mass. The mass was removed by parotidectomy for definitive diagnosis and treatment. We reviewed the findings in comparison with data in the literature.The well-encapsulated tumor arose from the superior branch of the intraparotid facial nerve. As the tumor could not be dissected from the nerve, a segment of facial nerve was sacrificed and repaired by interposing a greater auricular nerve. The final pathological diagnosis was schwannoma arising from the facial nerve.This case illustrates the clinical and pathologic features of intraparatid facial nerve schwannoma and points out the pitfalls of diagnosis and treatment. Consensus has recognized total resection surgery with facial nerve sacrifice as the most reasonable treatment for these tumors. We discuss the currently accepted management approach as well as the different treatment modalities for recovering facial function.

Two cases of internal carotid artery aneurysm arising within the petrous bone are described, bringing up to 56 the number of such cases reported to date in the medical literature scanned through Medline. The first case presented as a moderately bleeding tumor of the petrous apex, while the second was revealed by a massive otorrhage. In both cases a pulsatile nasopharyngeal mass was associated with otorrhage. The treatment required in both cases the aneurysm to be embolized in extreme emergency. One patient suffered transient hemiplegia and aphasia that completely recovered, while the second eventually died, although the carotid occlusion had been well tolerated in the first two weeks that followed this procedure. From their own experience and a literature review, we can emphasize the need for arterial extra-intracranial bypass before an aneurysm embolization be proposed, since the neurological issue following internal carotid occlusion cannot be predicted.

The meaning of facial nerve enhancement by gadolinium-enhanced magnetic resonanca imaging (MRI) in Bell's palsy is very discussed. Aim of our study was to define the radiological data in facial Bell's palsy and to correlate them with clinical data.34 patients with facial Bell's palsy were studied prospectively. Each patient had two gadolinium-enhanced MRI. The first MRI was realized during the first ten days. The second MRI was realized three months later. Two patients with facial nerve enhancement localized on the third portion was not clinically normalized at 3 months. Facial nerve enhancement and his precise location was noted.Facial nerve enhancement was noted in 71,5% on first MRI and in 30% on second MRI. Gadolinium-enhancement was predominantly noted on the Fundus. No patients with facial nerve enhancement persisting at three months was clinically normalized at one month.Facial nerve enhancement localized on the fundus and/or on the third portion, persisting at three months, could be consider as a negative landmark of fast clinical facial recuperation.

The efficacy of systemic antibiotics on the treatment of ventilator-associated infectious maxillary sinusitis (VAIMS) is debated. The objective of this study was to determine the etiologic diagnosis of VAIMS in patients receiving antibiotics.Patients mechanically ventilated for more than or equal to 72 h, who had persistent fever while on antibiotics for more than or equal to 48 h, underwent computed tomography scan followed by transnasal puncture of involved maxillary sinuses. VAIMS was defined as follows: fever greater than or equal to 38 degrees C, radiographic signs (air fluid level or opacification of maxillary sinuses on computed tomography scan), and a quantitative culture of sinus aspirate yielding more than or equal to 103 colony-forming units/ml.Twenty-four patients had radiographic signs of sinusitis. The mean +/- SD prior durations of mechanical ventilation and antibiotic exposure were 9.5 +/- 4.7 days and 6 +/- 4 days, respectively. Six unilateral and nine bilateral VAIMS were diagnosed in 15 patients. The median number of etiologic organisms per patient was two (range, one to four). The bacteriologic cultures yielded gram-positive bacteria (n = 21), gram-negative bacteria (n = 22), and yeasts (n = 5). Forty percent of causative agents were susceptible to the antibiotics prescribed. Seven patients with VAIMS developed 10 concomitant infections: ventilator-associated pneumonia (n = 5), urinary tract infection (n = 3), catheter infections (n = 2). In all cases of ventilator-associated pneumonia, the implicated agents were the causative agents of VAIMS.In VAIMS patients on antibiotics, quantitative cultures of sinus aspirates may contribute to establish the diagnosis. The frequent recovery of microorganisms susceptible to the antimicrobial treatment administered suggests that therapy of VAIMS with systemic antibiotics may not be sufficient.

The aim of this study was to test the hypothesis that optimism is a predictor of quality of life (QOL) in a sample of upper aerodigestive tract (UADT) cancer patients.Consenting patients with squamous cell carcinoma of the UADT were included during the week following disclosure of the diagnosis of their illness, and before the start of treatment. QOL and optimism were evaluated by questionnaires presented to the patients before the start of treatment, after the treatment, and 6 and 12 months after the end of the treatment.92 patients were included. The average age was 58.7+/-11.4 years. Their QOL scores were significantly correlated, first with age (r =- 0.23, p =0.03) and second with degree of optimism (r =0.32, p =0.002). No correlation was found between QOL scores, degree of optimism, and sociodemographic and clinical data. Optimism was the sole variable significantly associated with QOL before treatment (F =4.1, p =0.002, r(2) =0.19). The difference between QOL scores before and after treatment was not significant.Continuation of the study and analysis of survival of the patients may help pinpoint new prognostic factors, both objective and subjective, that will facilitate an overall approach to patient care by allowing for their preferences.

The aim of this study was to determine CT scan value for the follow-up of patients with pleuropulmonary lesions related to Wegener's granulomatosis.Retrospective study of ten patients who were diagnosed with diffuse Wegener's granulomatosis including lung involvement and for whom mean follow-up was 23 months (range 4-61).During early stages of the disease, the most common finding was the existence of either nodules (90% of the patients) or consolidations (100% of the patients). CT scan controls showed that nodules disappeared within 6 months in 60% of patients and had completely resolved after 12 months. Linear opacities relating to traction developed, replacing subpleural nodules. A pneumothorax occurred in two patients who had excavated subpleural nodules. Consolidations disappeared in 44% of the patients, most frequently within 4 months. When consolidations persisted, they were replaced by alveolar infiltrates accompanied by bronchiolectasies and linear opacities. Regarding either nodules or consolidations, CT features related to relapse were similar to those of initial lesions in 40% of the cases.The main features of pleuropulmonary lesions relating to Wegener's granulomatosis were subpleural nodules that either disappeared with, however, subsequent linear opacities sequelae, or were complicated by the occurrence of pneumothorax.

Acute postoperative pain has seldom been assessed in head and neck cancer surgery. The estimation of actual pain is more difficult when communication is impaired by tracheotomy or tracheostomia. The aim of the present prospective study was the assessment of analgesia level during the first 48 postoperative hours after head and neck cancer surgery. The analgesic procedure involved intra-venous morphine injected by means of a PCA pump (Patient controlled analgesia). Thirty patients were thus treated after cancer surgery of the larynx or the oropharynx. The protocol included during 48 hours the assessment of pain, using a visual analogic scale (VAS) every fourth hour, while recording the total injected dose of morphine, the localisation of pains, as well as the occurrence of side-effects. The control of postoperative pain was shown to be satisfactory, with a VAS grade smaller than 3 at time zero and kept below this value during 48 hours. At the end of this period, the mean total dose of morphine injected was 38 mg. No case of respiratory depression was even seen. It can be concluded that PCA seems to be an efficient procedure for controlling postoperative pain in head and neck cancer surgery. This technique proved to be better than delivering analgesia on requirement.

We conducted a retrospective study of six patients presenting a parapharyngeal tumor and an analysis of data of the literature and recall classification of these tumors and their anatomo-clinics characters, therapeutic and diagnostic problems highlighting. These tumors are rare and have various origins, their treatment is almost always surgical by cervical approach which can be undertaken only after a rigorous exploration, systematically associating computed tomography scan and magnetic resonance imaging. Transoral resection is strongly advised against as it is potentially harmful.

Inverted papillomas (IPs) are rare benign tumors of nasal epithelium with high recurrence rates and malignant transformation potential. Their etiology is still uncertain, and the mechanism of their growth has not yet been fully described. The purpose of this study was to detect, quantify, and compare cell proliferation, apoptosis, and apoptosis inhibition in hyperplastic epithelium from IPs and in inflammatory nasal polyps (NPs). IP samples were obtained after surgical removal of tumor in 13 patients, and NPs were sampled during endoscopic ethmoidectomy in 10 patients with nasal polyposis. Cell proliferation and apoptosis inhibition, respectively, were assessed by immunohistochemical identification of the proliferating cell nuclear antigen (PCNA) and the oncoprotein Bcl-2. Apoptosis was evaluated by analyzing the DNA fragmentation. Cell proliferation and apoptosis were significantly higher in IPs than in NPs (P = .0002 and P = .043, respectively), while apoptosis inhibition was significantly lower in IPs than in NPs (P = .001). Concerning IPs, cell proliferation was significantly higher than apoptosis (P = .0029) and apoptosis inhibition (P = .0015). The increase in epithelial cell proliferation seemed to be greater in IPs with dysplasia than in IPs without dysplasia. Increased epithelial cell proliferation, but not apoptosis and apoptosis inhibition, seems to be involved in the development of IP.

Postoperative pain has rarely been assessed after ENT surgery for cancer. Its evaluation is difficult because of the frequent lack of speech after this type of surgery.to assess postoperative pain after pharyngeal and laryngeal surgery for cancer.prospective study in 13 men (38-71 ans) operated on by total laryngectomy with or without partial pharyngectomy. A standardised treatment using propacetamol and nalbuphine was systematically prescribed. Pain, anxiety and relief were assessed with the help of visual analogue scales (VAS). Heart rate, mean blood pressure and respiratory rate were evaluated too.mean postoperative pain was maximal just after recovery (6,64 +/- 2,14 cm) then decreased regularly. Initial mean score of anxiety was 3,14 +/- 3 cm and then was decreasing too. Anxiety and pain did not correlate except in 2 cases. None of the 3 objective parameters correlated with pain.postoperative pain can be assessed reliably after pharyngolaryngeal cancer surgery and is probably underrated. Its high initial score indicates that efforts must be focused on pre-emotive analgesia. Its high individual variability let us hypothesise that PCA systems should be effective.

The authors report the case of a 75 years old insulin dependent diabetic man presenting a malignant otitis externa with facial nerve paralysis. Despite prolonged, adequate parenteral antibiotic therapy, the patient's clinical status did not improve. The addition of hyperbaric oxygen as a complementary treatment was followed by the regression of clinical signs and the resolution of infection. Based upon a review of the literature, the authors discuss the indications for this therapy and the problems involved in defining the criteria of cure in malignant otitis externa.

Eight inverted papillomas were evaluated for the presence of human papillomavirus (HPV) DNA. The techniques used were Southern Blot Hybridization in five cases and Polymerase Chain Reaction (PCR) in three cases. All eight lesions contained the characteristic features of inverted papillomas. Two lesions showed areas of dysplastic change and one lesion contained koilocytes. In three patients, invasive squamous cell carcinomas were found. The presence of HPV was noted in one of these specimen of inverted papilloma with squamous cell carcinoma. Specific testing for HPV types 6, 11, 16, 18 and 33 on this specimen was negative, thus indicating that the specimen is associated with a different HPV type. The results of this study, with only one case of positive HPV testing, leads us to question the precise role of HPV as an etiological agent in nasal inverted papillomas. The fact that this single positive case did not test positive for the HPV type 16 suggest that this is not the only "high risk" HPV type associated with the progression of inverted papilloma to a carcinoma.

Twelve patients with nasal polyposis were examined with magnetic resonance imaging (MRI) prior to surgical ethmoidectomies (20 ethmoidectomies). MRI signal was analyzed in correlation with surgical findings in order to define the semiology of nasal and sinuses polyps. One of the most important point of this semiology is based on the analysis of sequences after administration of gadolinium. MRI seems an interesting method for analysing the extension of nasal polyposis and could be useful for ENT surgeons before an endoscopic nasal surgery.

Of a total of 219 partial laryngectomies performed, 119 were cordectomies, 30 hemilaryngectomies and 70 supraglottic laryngectomies. Results of each type of operation are presented with emphasis on problems of local recurrences, evidence of validity of procedure selected and of its indications. Analysis of results, with the reservation that indications were sometimes wide but always reasonable, showed an extremely low incidence of recurrences, the quality of the resection (limited or insufficient) having finally little incidence on the latter, except perhaps in the supraglottic laryngectomies. It is suggested, therefore, that no attempt should be made to "recover" a histologically detected insufficient excision by complementary radiotherapy not required in principle. This assists follow up review and allows secondary therapy if an unfavorable course is noted.

The authors report on 48 patients operated by hemi-laryngo-pharyngectomy for spinous carcinoma of the piriform sinus. They try to precise the indications by analysing the factors influencing survival and relapses. They compare surgery to the other methods. In a second part, they report 3 cases of posterior pharyngectomy by bilateral cervical incision.
