Risk of laryngeal edema and facial swellings after tooth extraction in patients with hereditary angioedema with and without prophylaxis with C1 inhib…

2010

Objective Tooth extractions may trigger clinical symptoms of hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH). The aim of this study was to determine how many tooth extractions were followed by symptoms of HAE-C1-INH in patients with and without preoperative short-term prophylaxis with C1 inhibitor concentrate. Study design Tooth extractions and clinical symptoms of HAE-C1-INH were determined from clinical record files of 171 patients with HAE-C1-INH. Results Facial swelling or potentially life-threatening laryngeal edema, or both, occurred in 124/577 tooth extractions (21.5%) without prophylaxis. Similar symptoms occurred in a fewer proportion of patients undergoing extrac…

Acute tissue damage induced by monopolar microelectrodes and radiofrequency in vocal cords after transoral cordectomy

2021

Abstract Introduction: In 2006 and 2009, we reported the levels of acute and chronic tissue damage after cordectomy associated with use of the microlectrodes using high frequency energy. In 2010, we shifted to radiofrequency rather than high frequency electrogenerators. Objective: The aim of this study is to evaluate acute tissue damage in the larynx after cordectomy using microelectrodes coupled to a radiofrequencygenerator. Methods: We studied 22 patients with a stage T1 glottic squamous cell carcinoma. The patients were randomly assigned to the two operating mode: cutting or coagulation (11 patients each mode). The strength of the study is that there are no previous studies on the effect…

Differential expression levels of urokinase-type plasminogen activator and cathepsin D in locally advanced laryngeal squamous cell carcinoma: Clinica…

2002

The expression levels and the prognostic impact of urokinase-type plasminogen activator (uPA) and cathepsin D (CD) were evaluated in patients with locally advanced laryngeal squamous cell carcinoma (LSCC). uPA and CD protein levels were determined by immunoluminometric or immunoenzymatic assays in the cytosol of paired sets of tumor tissues and corresponding adjacent normal mucosa (NLM) from 57 patients with stage III/IV LSCC and were correlated with a number of clinicobiological parameters of this tumor including anatomical site, tumor grade, nodal status, clinical stage, DNA ploidy, proliferation rate, and patient outcome. Median uPA levels were significantly higher in LSCC than in NLM (…

Recurrence of a laryngeal spindle cell sarcoma with a transformation into a higher grade of malignancy.

2009

Primary malignant mesenchymal neoplasms of the larynx are rare. Sarcomas of the larynx account for <1% of all malignant laryngeal mesenchymal neoplasms. This report examines a case of a recurring laryngeal, initial benign-appearing mesenchymal tumour, which first changed its clinical phenotype without any histological signs of malignancy and later also its histological appearance with signs of malignancy. Finally, it even underwent a transformation into a higher grade of malignancy. In addition to this, the difficulties of allocating this tumour to the correct sarcoma subentity are shown.

Basaloid squamous cell carcinoma: report of five cases.

2009

Objectives: To document the clinical and histopathological characteristics of basaloid squamous cell carcinoma (BSCC). To add five new cases to the literature and compare them with another published series. Cases: retrospective review of five cases with the diagnosis of BSCC of the larynx. Results: all the patients were male. They were heavy smokers and drinkers. Most of the tumours were supraglottic. Three patients presented with stage-IV disease and the other two with stage-I disease. Surgery supplemented with radiation was used in three patients, partial surgery was used in another case and radiation and associated chemotherapy in the other one. Eight neck dissections were performed, six…

Treatment of bilateral vocal cord paralysis following permanent recurrent laryngeal nerve injury.

2012

Bilateral vocal cord paralysis is a serious illness requiring emergency intervention to resolve the potentially life-threatening respiratory distress. Several surgical procedures were proposed to help improve the airway and to eliminate the tracheostoma in those patients with permanent paralysis. All the procedures have their own advantages and disadvantages. We conducted a retrospective study of 30 patients affected by bilateral vocal cord paralysis following total thyroidectomy. All the patients underwent total thyroidectomy for benign thyroid pathology. In 26 patients (86.6%), cord paralysis occurred during the perioperative stage; and in the remaining 4 cases (13.3%), it occurred within…

Head and neck squamous cell carcinoma in people living with HIV in France.

2018

Abstract Objectives Head and neck squamous cell carcinoma (HNSCC), mainly due to smoking, is one of the leading causes of cancer deaths. However, an increasing number of tumors – especially oropharyngeal cancer – are reported in non-smokers in association with the human papillomavirus (HPV). As HIV-infected individuals are particularly at risk of HPV-related disease, we aimed to describe the burden of HNSCC in this population. Methods Retrospective chart review of patients from HIV clinics diagnosed with HNSCC between 2004 and 2014. Case patients were defined using the International Classification of Disease for Oncology (3rd edition). Age at HIV diagnosis and time from HIV diagnosis to HNS…

Thyroid cartilage involvement in patient affected by IgA multiple myeloma: case report.

2008

Neoplasms originating from plasma cell are rare in the head and neck region. A correct clinical evaluation is very important in order to formulate a differential diagnosis as well as to distinguish local from metastatic disease. We report a case of larynx involvement by an IgA multiple myeloma in a 69-year-old female diagnosed in October 2004 and treated with chemotherapy; the 1 year control do not show progression of disease and the laryngeal lesion is unchanged. We highlight the radiological findings and clinical features to suspect plasma cell tumors in cases with a similar presentation.

Radiosurgery in the treatment of laryngeal abductor paralysis

2003

Abstract Abductor true vocal cord paralysis is a complex condition that requires the surgeon to perform an emergency tracheotomy to eliminate the symptom of dyspnea. Throughout the past 20 years, corrective surgery has reverted to techniques using external or endoscopic techniques. For 5 years now, we have used high frequency radiosurgery by Ellman to treat various ENT conditions in our clinic. The experience we have gained has encouraged us to use this method in endoscopic surgery as well, in the treatment of laryngeal abductor paralysis under suspension microlaryngoscopy. Twelve patients were examined between 1999 and 2002. Diagnosis was performed through flexible fiberoptic videolaryngos…

Gastric insufflation pressure, air leakage and respiratory mechanics in the use of the laryngeal mask airway (LMA) in children.

2004

Summary Background : The objective of the present study was to evaluate the prelaryngeal position of the laryngeal mask airway (LMATM) in children, and to determine the influence of mask positioning on gastric insufflation and oropharyngeal air leakage. Methods : A total of 100 children, 3–11 years old, scheduled for surgical procedures in the supine position under general anaesthesia were studied. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 30 cmH2O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relation to the laryngeal entrance was verified using…
