PURPOSE: A collision tumor consists of 2 different histologically distinct and topographically independent tumors merging in the same mass. In the head and neck region they are rare, with only 4 cases reported in the larynx. CASE REPORT: A 60-year-old heavy smoker complained of a left submandibular lesion in October 2014. The lesion was excised and showed a poorly differentiated carcinoma, suggestive for adenocarcinoma. After a positron emission tomography-computed tomography scan showed increased metabolic activity in the left laterocervical region and right vocal cord, the patient underwent endoscopic biopsy of the lesion of the left piriform sinus, which was positive for moderately differentiated squamous cell carcinoma (SCC)...

For locally advanced laryngeal cancers, the standard treatment of choice is chemoradiotherapy if organ function needs to be conserved. Surgical treatment with larynx preservation is conducted only for limited cases. For locally advanced laryngeal cancers such as those with vocal cord fixation and/or cricoid cartilage destruction, there is no apparent standardized organ-preserving surgery keeping the essential laryngeal functions, viz. the airway, deglutition and articulation, uncompromized. Recently, our surgical team saw a patient with T4a advanced laryngeal cancer with vocal cord fixation who aspired to maintain his laryngeal function...

Intubating newborn infants can be exacting. We describe two cases of endotracheal intubations in infants born with tracheal malformations. A male infant aged 30 weeks required intubation at birth for respiratory distress. Repeated attempts at intubation failed to achieve an optimal endotracheal tube position as the tube could not advance beyond the vocal cords. Hence ventilation continued with suboptimal air entry in the lungs. Bronchoscopy and CT scan confirmed tracheal stenosis. Slide tracheoplasty was successfully executed on day 78 of life...

RATIONALE: Recurrent laryngeal nerve block is an uncommon complication that can occur after an interscalene brachial plexus block (ISB), which may lead to vocal cord palsy or paresis. However, if the recurrent laryngeal nerve is blocked in patients with a preexisting contralateral vocal cord palsy following neck surgery, this may lead to devastating acute respiratory failure. Thus, ISB is contraindicated in patients with contralateral vocal cord lesion. To the best of our knowledge, there are no reports of bilateral vocal cord paresis, which occurred after a continuous ISB and endotracheal intubation in a patient with no history of vocal cord injury or surgery of the neck...

INTRODUCTION: Epilepsy is one of the most common neurologic disorders. Vagus nerve stimulation (VNS), first investigated in 1938 and subsequently studied as a potential therapy for epilepsy. The FDA approved the use of VNS in 1997 as an adjunctive non-pharmacologic symptomatic treatment option for refractory epilepsy for adults and adolescents over 12years. VNS can cause laryngeal and voice side effects that can be managed by otolaryngologists safely and effectively. OBJECTIVES: This study is to review the outcomes of vagal nerve stimulator (VNS) implantation in terms of the surgical procedures, complications, seizure frequency, and the clinical effect on larynx and vocal folds motion...

Indications for vagus nerve stimulation (VNS) therapy include focal, multifocal epilepsy, drop attacks (tonic/atonic seizures), Lennox-Gastaut syndrome, tuberous sclerosis complex (TSC)-related multifocal epilepsy, and unsuccessful resective surgery. Surgical outcome is about 50-60% for seizures control, and may also improve mood, cognition, and memory. On this basis, VNS has also been proposed for the treatment of major depression and Alzheimer's' disease. The vagus nerve stimulator must be implanted with blunt technique on the left side to avoid cardiac side effects through the classic approach for anterior cervical discectomy...

INTRODUCTION: A sustained and effective oropharyngeal sealing with supraglottic airway is required to maintain the ventilation during laparoscopic surgery. Previous studies have observed the Oropharyngeal Seal Pressure (OSP) for Proseal Laryngeal Mask Airway (PLMA) after pneumoperitoneum in supine and trendelenburg position, where PLMA was found to be an effective airway device. This study was conducted with ProSeal LMA, for laparoscopic Urologic procedures done in lateral position. AIM: To measure OSP in supine and lateral position and to observe the effect of pneumoperitoneum in lateral position on OSP...

BACKGROUND: The Non-Recurrent Laryngeal Nerve (NRLN) is a rare embryologically-derived variant of the Recurrent Laryngeal Nerve (RLN). The presence of an NRLN significantly increases the risk of iatrogenic injury and operative complications. Our aim was to provide a comprehensive meta-analysis of the overall prevalence of the NRLN, its origin, and its association with an aberrant subclavian artery. METHODS: Through March 2016, a database search was performed of PubMed, CNKI, ScienceDirect, EMBASE, BIOSIS, SciELO, and Web of Science...

Endotracheal tube (ETT) should be placed at the optimal level to avoid single lung ventilation or accidental extubation. This study was performed to estimate the mid-tracheal level by using surface anatomical landmarks in adult patients.Neck computed tomography images of 329 adult patients between the ages of 16 and 79 years were reviewed. In the midline sagittal plane, the levels corresponding to the vocal cords, cricoid cartilage, suprasternal notch, manubriosternal junction, and carina were identified. The surface distances from the cricoid cartilage to the suprasternal notch (extCC-SSN) and that from the suprasternal notch to the manubriosternal junction (extSSN-MSJ) were measured...

Celeste Porsbjerg, Andrew Menzies-Gow
Patients with severe asthma represent a minority of the total asthma population, but carry a majority of the morbidity and healthcare costs. Achieving better asthma control in this group of patients is therefore of key importance. Systematic assessment of patients with possible severe asthma to identify treatment barriers and triggers of asthma symptoms, including co-morbidities, improves asthma control and reduces healthcare costs and is recommended by international guidelines on management of severe asthma...
