RESUMEN

BACKGROUND: Over the past decade, therapeutic options in head and neck supraglottic squamous cell carcinoma have constantly evolved. The classical total laryngectomy has been partially replaced by alternative organ- and function-sparing techniques with the same prognosis but less morbidity, such as Radiotherapy, Transoral Laser Microsurgery (TLM) and Trans-Oral Robotic Surgery (TORS). Up to now, a prospective comparison of these innovant techniques has not been conducted. METHODS/DESIGN: We will conduct an original international multicentric prospective nonrandomized clinical trial to compare the efficacy between these treatments (Arm 1: Radiotherapy ± chemotherapy; Arm 2: TLM and Arm 3: TORS) with 4 classes of outcomes: quality of life (QoL), oncological outcomes, functional outcomes and economic resources. The population will include cT1-T2 /cN0-N1/M0 supraglottic squamous cell carcinoma. The primary outcome is a Clinical Dysphagia QoL evaluation assessed by the MD Anderson Dysphagia questionnaire. Secondary outcomes include others QoL evaluation, oncological and functional measures and cost parameters. The sample size needs to reach 36 patients per arm (total 108). DISCUSSION: In the current literature, no prospective head-to-head trials are available to compare objectively these different treatments. With the increase of highly efficient treatments and the increase of oncological survival, it is imperative also to develop management strategies that optimize QoL and functional results. We will conduct this innovate prospective trial in order to obtain objective data in these two main issues. TRIAL REGISTRATION: NCT05611515 posted on 10/11/2022 (clinicaltrial.fgov).

RESUMEN

PURPOSE: Spasmodic dysphonia (SD) or laryngeal dystonia is as a rare vocal disorder characterized by involuntary action-induced endolaryngeal contraction. In the last decade, botulin toxin injection has become the standard treatment in adductor spasmodic dysphonia necessitating repetitive injections. The purpose of this study is to analyze retrospectively data from patients treated with the minimal-invasive transoral radiofrequency-induced thermotherapy (RFITT) of the terminal branches of the recurrent nerve. METHODS: Between 2009 and 2015, 11 patients (six females and five males aged from 32 to 91 years) with adductor SD were treated with RFITT. Pre-operative and post-operative vocal assessments (VHI-30, GRBASI, and acoustic-aerodynamics measurements), number of surgical revisions, delay between procedures, and post-operative complications were recorded. Statistical analyses were carried out on the first vocal assessment performed 2-8 weeks after the first procedure. RESULTS: Based on available data from ten patients, voice handicap index (VHI) showed improvement with a mean value of -17.7 points (p-value (pval) = 0.014, adjusted p-value (adj pval) = 0.21); instability has also revealed improvement in six patients (pval = 0.05, adj pval = 0.31). Four patients underwent only one procedure including one patient showing still long-term beneficial results after 5 years of follow-up. Other patients required one to three new procedures with an average time between procedures of 15.3 months. Over 24 surgeries performed on a total of 11 patients, one definitive treatment-related severe adverse event was reported. CONCLUSION: Thanks to long-lasting effect, repetitive treatments are less frequent compared to botulin toxin therapy. In our opinion, RFITT is a promising alternative to botulin toxin as a second-step procedure in case of toxin resistance or patient's lack of compliance.

RESUMEN

Gout is the most common cause of monoarthritis in men occurring classically in the great toe and the knee. Extra-articular gout manifestations are rare. Only a few cases of head and neck urate crystals deposits have been described in the literature. Precipitations in the middle ear cause conductive hearing loss with common otoscopic anomalies and difficult imaging diagnosis. We report a case of a healthy 58-years-old man with a middle ear urate deposit causing a progressive hearing loss as the very first symptom of gout. The nature of the deposit was unsure on computer tomography (CT) due to atypical density. The final diagnosis was revealed after surgical procedure and histologic examination. A review of the literature is also presented. Seven cases of middle ear urate deposit as the first symptom of gout were found and compared. Progressive conductive hearing loss in middle-aged patients with abnormal otoscopy and middle ear atypical density mass on CT scan must lead to a minimal surgical procedure with a histologic examination to exclude urate crystals deposits.

RESUMEN

Thoracic ultrasound (TUS) is increasingly studied in neonatal respiratory distress but chest x-ray (CXR) remains the first-line exam. We aimed to evaluate its diagnostic performance for the investigation of unselected causes of neonatal respiratory distress in daily practice. We conducted a descriptive, prospective, and single-center diagnostic accuracy study in a tertiary hospital, including term and preterm newborns who needed a CXR because of respiratory conditions occurring at birth or during the first 24h of life. TUS was compared to the reference diagnosis, which was the association between the CXR results, the clinical initial context, and the patient's outcome. Fifty-two newborns were included and 104 hemi-thorax ultrasounds were analyzed. Sensitivity, specificity, positive and negative predictive values (PPV, NPV), diagnosis accuracy, as well as the positive and negative likelihood ratio of TUSs were 100% for respiratory distress syndrome (RDS), transient tachypnea of newborn (TTN), pneumomediastinum, meconium aspiration syndrome, and absence of pulmonary disease. TUS also showed 100% sensitivity and NPV for pneumothorax, but specificity was 97% and PPV was 50%. Kappa concordance between TUS and either CXR alone or the radiological/clinical gold standard was 0.79 and 0.95, respectively. CONCLUSION: TUS at the newborn's bedside is efficient for investigating the main neonatal respiratory diseases, especially for the confirmation of RDS or TTN and for the exclusion of differential diagnosis or complications.

RESUMEN

UNLABELLED: PROBLEM/OBJECTIVES: Epistaxis is the most common manifestation of hereditary hemorrhagic telangiectasia (HHT); it is present in >90% of HHT patients > 45 years old. Depending on severity, treatment consists of managing bleeding via medical and surgical methods. The aim of our study was to evaluate the efficacy and safety of endonasal surgical arterial cauterization to treat chronic epistaxis in patients with HHT who are no longer responding to first-line therapies. METHODOLOGY: Five patients were included in our study. The day before surgery, all patients underwent devascularization embolization of the external carotid arterial branches involved in nasal bleeding. The primary efficacy endpoint of treatment was assessed by the Epistaxis Severity Score (ESS), which was systematically evaluated preoperatively in our department, as well as every 3 months postoperatively. Data were collected retrospectively from the medical records of patients. RESULTS: Endonasal surgical arterial cauterization was associated with a ≥ 50% reduction in the ESS up to 9 months postoperatively. In one of our patients, cerebrospinal fluid (CSF) leakage occurred intraoperatively during cauterization of the posterior ethmoid artery. Closure of the dural skull base defect was successfully performed intraoperatively. DISCUSSION: Although our results are preliminary and included few patients, they support a role for endonasal surgical arterial cauterization as a second-line treatment method for chronic epistaxis in patients with HHT.

RESUMEN

Tinnitus is a common symptom, affecting nearly 10% of the adult population. Even if most of the patients support it, it can be particularly disabling in some cases. Recent advances in neuroscience have greatly improved the understanding of its pathophysiology, resulting in development of new therapeutic strategies. The management of tinnitus requires a systematic and rational approach to avoid incomplete diagnosis procedures and unnecessary exams. The diagnostic approach will be held to identify the causal pathology. Etiological treatment, if it is possible, will be the first therapeutic step. Various symptomatic treatments, such as tinnitus retraining therapy, cognitive behavioral therapy, or neuromodulation will promote habituation to the tinnitus, to ensure that the latter won't cause discomfort anymore.

RESUMEN

Rhinosinusitis is an important health problem which is increasing in frequency and which has a large financial repercussion on society. Better understanding of ARS management has modified our clinical approach leading us to minimize unnecessary use of radiological investigations, overuse of antibiotics, and improve the under utilisation of nasal corticosteroids. The goal of this article is to present important new guidelines mainly based on the European position paper on rhinosinusitis and nasal polyps 2012 (EPOS 2012) in order to facilitate ARS management in general practice.

RESUMEN

OBJECTIVE: We report a pregnant patient with a rapidly growing mass within the nasal cavity, which required pre-operative super-selective embolisation and subsequent removal under general anaesthesia after childbirth. We also discuss the clinical, radiological and histological characteristics of lobular capillary haemangioma, and its treatment. METHOD: Case report and literature review. RESULTS: Lobular capillary haemangioma is a benign lesion originating in the vascular tissue of skin, mucosa, muscles, glands and bone. These lesions grow rapidly. Nasal localisation is rare. Microtrauma and pregnancy are the most commonly proposed aetiological factors. Reported incidence during pregnancy ranges from less than 2 per cent to approximately 5 per cent. The management of a pregnant woman with such a lesion may be complex, and depends on the severity of symptoms and the status of the pregnancy. Complete surgical excision, with or without pre-operative embolisation, is the treatment of choice. CONCLUSION: This uncommon lesion should be considered in any pregnant patient with a mass in the mouth or nasal cavity.

RESUMEN

Draf in 1991. The procedure--which is also known as the modified endoscopic Lothrop procedure--aims to create the largest possible anteroposterior and lateral to lateral opening between both frontal sinuses and the nasal cavities. This requires the resection of the medial floor of both frontal sinuses, the intersinus septum and the superior nasal septum. The authors present a retrospective study including a cohort of 120 patients who underwent surgery in six Belgian university ENT departments. Mean follow-up was 24.6 months (range: 5-36 months). This paper describes the surgical procedure and reviews the indications, comorbidities, outcomes and complications of the type III frontal sinusotomy. Some correlations are also established with the data published in the worldwide literature. The authors conclude that the Draf III is a demanding procedure requiring considerable expertise in endoscopic sinus surgery. The procedure is effective with a success rate of 87.5%. Indeed, 12.5% of patients only experienced closure of the neoostium while 20% of all the patients had unchanged or worse symptomatology. The percentage of post-operative complications is 7.5%. All complications were managed successfully.

RESUMEN

OBJECTIVE: The aim of this study was to analyse the results of minimally invasive endoscopic unilateral transsphenoidal surgery for pituitary adenomas. METHODS: A series of 83 patients presenting with a pituitary lesion was reviewed retrospectively. Surgical procedures were performed between February 2007 and December 2010. The extent of resection was evaluated on post-operative contrast-enhanced MRI. We also reviewed our complications and compared them with the literature. RESULTS: Our series included 10 micro- and 73 macro-adenomas, with cavernous sinus invasion in 60.3%. Fifty-three per cent were non-secreting. Complete resection of the macro-adenomas was achieved in 22.5% of the cases. Complications were as follows: 2 deaths (2.5%), 2 sinusitis (2.5%), 5 CSF leaks (6.2%), 1 meningitis (1.2%), 16 post-operative anterior lobe insufficiency (19.8%) and 4 persistent diabetes insipidus (4.9%). Thirty-seven patients (44.6%) presented with a compression of optical pathways with an improvement of visual acuity in 94.3%. CONCLUSIONS: Purely endoscopic unilateral endonasal transsphenoidal adenoma resection is minimally invasive surgery leading to a good rate of gross total tumour resection and it is associated with a low complication rate.

RESUMEN

The management of hypervascular skull base tumours is complex and requires a multidisciplinary approach. Skull base surgery may be challenging because of the risk of serious intra-operative bleeding and of potential injuries to lower cranial nerves and/or large cervical vessels. Over the last four decades, advances in neuro-interventional procedures have produced a range of adjunctive endovascular techniques in addition to conventional surgery. Digital subtraction angiography (DSA) allows for a better understanding of tumour vascularisation and its relationship with Surrounding vessels. Tumoural devascularisation and the occlusion of feeding arteries is a useful adjunct to surgery because it allows for the reduction of intra-operative blood loss and induces ischaemic necrosis of the tumour. Finally, surgery-related iatrogenic vascular lesions may be successfully treated with endovascular techniques. Nevertheless, endovascular procedures in the head and neck region are associated with infrequent but potentially serious complications. An extensive and comprehensive knowledge of head and neck vascular anatomy is therefore necessary. This article provides a review of the indications for, and results of, diagnostic, pre-operative and therapeutic endovascular procedures for the management of skull base tumours and related surgical complications.

RESUMEN

INTRODUCTION: Leksel Gamma Knife (LGK) radiosurgery is a safe and efficient therapeutic approach for vestibular schwannoma (VS) with low side effects. The goal of radiosurgery is not necessarily to cause significant tumour necrosis or to obtain a complete radiographic response, but to halt the tumour's growth permanently through its biological elimination. The 2 major aims of radiosurgery for VS are long-term tumour control and functional hearing preservation. The purpose of this study is to report our experience with LGK radiosurgery in the management of VS and to evaluate the hearing preservation rate after a minimum one-year follow-up. MATERIAL AND METHODS: Between January 2000 and January 2011, 415 patients with unilateral VS underwent LGK radiosurgery at the University Erasmus Hospital of Brussels. There were 349 patients with previously untreated VS (86 grade I, 96 grade II, 141 grade III, 9 grade IVa, 17 unknown grades, according to Koos) and 66 patients with post-operative residual tumour. All patients in our series underwent evaluation with high resolution neurodiagnostic imaging including computed tomography and magnetic resonance imaging, and clinical evaluation as well as audiological tests that included tonal and speech audiometries. The Gardner Robertson (GR) classification is used to report the results of this study. We identified 276 patients treated for VS with LGK, tested and retested with speech and tonal audiometries by the same team, and followed for a minimum of one year. RESULTS: Before LGK, 144 patients had serviceable (85 GR class I and 59 GR class II) hearing; 95 (65.97%) of these patients had preservation of serviceable hearing (Pure tone average < or = 50 db and Speech discrimination > or = 50%) at minimum one-year audiological follow-up. It was observed that 44 of the 85 GR class I patients (51.76%) maintained their level of audition and 66 of these (74.64%) preserved serviceable hearing. In the 34 patients with preradiosurgery non-serviceable hearing (GR class III-IV) 25 of these patients (73.52%) maintained their hearing. The tumour was stable or declining in size in 90.44% of cases. CONCLUSION: LGK radiosurgery provides excellent tumour control in vestibular schwannomas and has low toxicity even after long-term follow-up.

RESUMEN

Congenital tuberculosis is a rare but severe disease. Diagnosis is often delayed, especially in preterm neonates. We report a premature infant born after 27 weeks of gestation and in vitro fertilization. Tuberculosis was suspected after 112 days of life in view of sepsis, respiratory distress, and the discovery of maternal tuberculosis. Mycobacterium tuberculosis was isolated in endotracheal aspirates, gastric aspirates, and stools. The infant initially received four antitubercular antibiotics over 3 months, then two antibiotics over 9 months. A wide screening for a possible nosocomial transmission from this index case was set up. At the chronological age of 2 years, the baby is healthy without after-effects and no secondary cases were diagnosed. This article recalls the difficulty diagnosing congenital tuberculosis, particularly in preterm neonates. It also underlines the need to raise and eliminate the diagnosis of tuberculosis in an infertile woman.

RESUMEN

Unusual presentation of adenoid cystic carcinoma of the maxillary antrum. Adenoid cystic carcinoma (ACC) is a rare tumour which affects mainly the major and accessory salivary glands. It is an aggressive neoplasm characterized by early neural invasion and a high incidence of local recurrence and distant metastases, which may develop years after the initial resection. Surgery followed by radiotherapy seems to be the best treatment. Based on a well-illustrated case of extensive maxillary ACC involving the palate, orbit floor, and pterygo-palatine fossa, we discuss the prognosis and the importance of an early diagnosis of ACC.

RESUMEN

BACKGROUND: Nasal polyposis is a model for the study of inflammatory processes. We analyzed the expression of galectin-7, a growth regulator, in surface epithelium, glandular epithelium, and connective tissue in human nasal polyps, and examined the effect of the glucocorticoid budesonide on its expression in human nasal polyps ex vivo. METHODS: Using quantitative, computer-assisted microscopy and immunohistochemistry, we measured galectin-7 expression in nine nasal polyps obtained by surgical resection. Five polyps came from allergic patients and four came from non-allergic patients. RESULTS: Galectin-7 was expressed in all three polyp tissues analyzed. Treatment of polyps from allergic and non-allergic patients with 50 ng/ml budesonide increased the extent of galectin-7 expression in the connective tissue (p = 0.01). Conversely, budesonide at this concentration did not apparently affect galectin-7 expression in glandular epithelium; only a slight decrease in the percentage of the galectin-7-immunopositive cells was observed. In the surface epithelium of nasal polyps from non-allergic patients, the percentage of galectin-7-immunopositive cells was decreased (p = 0.03) by treatment with 250 ng/ml budesonide. In nasal polyps from allergic patients, this percentage was increased by treatment with 50 ng/ml budesonide (p = 0.0001). CONCLUSIONS: These data are consistent with a role for galectin-7 in the regulation of cell growth through a pro-apoptotic effect. Galectin-7 expression coincides with the degree of epithelial stratification, and is subject to upregulation in the connective tissue in response to treatment with 50 ng/ml budesonide. Budesonide modulates galectin-7 expression differently in the surface epithelia of polyps from allergic and non-allergic patients.

RESUMEN

Mucormycosis is a rare disorder with a potentially lethal course caused by an opportunistic fungus of the Phycomycetes family. Rhinocerebral mucormycosis (RCM) is an acute fulminant form of invasive fungal sinusitis occurring principally in individuals who are immunologically or metabolically compromised. This form originates from one of the paranasal sinuses and may spread to the orbit or the intracranial space either by direct extension or using the unique capability of spreading along vascular walls, leaving the bony structure intact. Carotid artery occlusion is a complication of RCM. Because of the rapidity with which this disease progresses, prompt and aggressive therapy is essential. The morbidity and mortality of this disease are directly related to the length of time before diagnosis and treatment. The diagnosis is difficult because invasive mucormycosis may be present with no mucosal changes and a normal sinus CT scan. It is a histological diagnosis. Treatment of RCM includes early diagnosis, correction of underlying conditions, early and radical surgical debridement, and lipid formulation of amphotericin B. Multiple surgeries are often necessary for adequate debridement. We report a case of carotid artery occlusion due to RCM and discuss the literature on its early signs and symptoms, pathophysiology, and treatment options.

RESUMEN

Congenital laryngeal cysts are rare and can cause upper airway obstruction if they are misdiagnosed. We describe a case of large vallecular cyst diagnosed at 33 weeks of gestation. The purpose of an early diagnosis is to establish a careful perinatal management. If the airway is compromised, a multidisciplinary medical team is necessary to perform emergency immediate tracheostomy. Elective delivery should be always carried out in a tertiary referral center.

RESUMEN

We report the case of a man presenting a deafness and a hemorrhagic ear discharge since one year. CT scanner and MRI reveal an invasive tumoral lesion of the external auditory meatus (EAM) expending into the posterior fossa. After surgery the diagnosis of high grade ceruminal gland adenocarcinoma is established whereas the malignancy was not obvious on earlier biopsy. Cancers arising in the EAM are uncommon and are essentially representating by squamous cell cancers and basal cell cancers. The precise diagnosis of a glandular tumor is a challenge for the pathologist because the limits between benign and malignant tumors are not obvious. Integration of clinical and radiological behavior and the histology of the tumor is necessary for a early diagnosis and a complete surgery.
