Chondrosarcoma is categorized as a malignant cartilaginous tumor, which occurs rarely in the craniofacial region. We report the case of a 68-year-old man with chondrosarcoma in the subglottic area. His chief symptoms were hoarseness and mild dysphagia. A computed tomography scan revealed a lesion with expansion of the cricoid cartilage and marked reduction of the airway. After biopsy, histologi...

BACKGROUND A quantitative understanding of airway sizes and proportions and a reference point for comparisons are important to a pediatric bronchoscopist. The aims of this study were to measure large airway areas, and define proportions and factors that influence airway size in children. METHODS A validated videobronchoscope technique was used to measure in-vivo airway cross-sectional areas (...

BACKGROUND Recent studies have challenged the historically accepted fact that the larynx is cone-shaped in infants and children. The present study used computed tomography (CT)-based measurements to evaluate airway dimensions. The purpose of this investigation was to determine the dimensional transition between the subglottic area and the cricoid ring in children. METHODS This is a retrospect...

Size and distensibility of large airways have important implications for flow limitation and the efficacy of coughing. From radiological and functional data, some authors have suggested an increased size and distensibility of the trachea in cystic fibrosis (CF). Using computed tomography (CT) we compared size and distensibility of the trachea in 5 cystic fibrosis patients and five age- and heig...

An elderly man with advanced esophageal cancer arrives in the operating room: his feeding tube has migrated out of his jejunum, spilling debris and bacteria into a previously sterile abdominal cavity. The OR clock fluoresces “2 AM.” With the patient’s immune system ringing alarm bells, his body has mobilized for biological warfare. His pulse races ... breathing hurries ... temperature climbs. A...

BACKGROUND Laryngeal chondrosarcoma (LCS) is a rare laryngeal tumor that most commonly originates from the cricoid cartilage. The current trend for treatment of low-grade LCS is function-sparing surgical option with negative margins. CASE SUMMARY We reported here a case of a 63-year-old male patient with a 3-month history of progressive hoarseness and throat pain. The patient had undergone su...

UNLABELLED To find the faster and easier way than the existing intubating technique for double-lumen tube, we modified the angle of double-lumen tube according to an individual's upper airway anatomy and compared the time needed and the number of attempts for successful intubation between individually angle-modified and non-modified double-lumen tubes. Adult patients undergoing elective thoraci...

OBJECTIVES/HYPOTHESIS Vocal cord scar formation and laryngotracheal stenosis (LTS) are challenging problems for otolaryngologists. Sendai virus (SeV) vectors have been shown to transduce airway epithelium efficiently, and are thus ideal for modulating airway wound-healing therapy. To assess the potential utility of SeV gene therapy for laryngotracheal diseases, we established a novel LTS model ...
