The tracheas of 12 patients who had undergone autopsies after percutaneous dilatational tracheotomy (PDT) were analyzed macroscopically and microscopically. The puncture site of the trachea varied from just below the cricoid cartilage (two patients) to below the third ring (three patients). A fracture of one or more tracheal rings was present in 11 patients, of whom 2 had a fractured cricoid. D...

Acute laryngeal injury is a rare, potentially lethal injury. It often poses difficulty in airway management. Commonly described are external laryngeal or blunt injuries. We report a case of penetrating neck injury resulting in complete transection of cricoid cartilage. A lady presented with a large, deep slash wound in her neck from a knife injury. There was complete laryngotracheal separation....

OBJECTIVE Partial cricotracheal resection has become a more popular procedure in the pediatric population as a treatment for severe subglottic stenosis. We describe a new technique for the posterior cricoid anastomosis. STUDY DESIGN AND SETTING This is a case series of 4 pediatric patients with a Myer-Cotton grade III or IV subglottic stensosis. SETTING Tertiary care hospital with a pediatr...

INTRODUCTION Squamous cell carcinoma of the larynx and hypopharynx has the potential to invade the thyroid gland. Despite this risk, the proposition of either partial or total thyroidectomy as part of the surgical treatment of all such cases remains controversial. OBJECTIVES To evaluate the frequency of invasion of the thyroid gland in patients with advanced laryngeal or hypopharyngeal squamo...

OBJECTIVES Functional surgery of unilateral T(2b) to T3 glottic cancer and cricoid chondrosarcoma is possible using the technique of tracheal autotransplantation. The objective of this paper is to report the functional and oncologic outcome of 24 consecutive patients treated with this technique between 2001 and 2007. METHODS Seventeen patients, of whom nine were previously irradiated, had uni...

A 62-year-old woman presented with symptoms of dyspnea. Ultrasonography and computed tomography examinations revealed mass extending from the cricoid cartilage to the left lobe of thyroid gland and thyroid cartilage. Cytology revealed possibility of cartilaginous origin, which was proven to be chondrosarcoma Grade 1 from the biopsy specimen obtained during panendoscopy. She underwent one stage ...

OBJECTIVES This report provides a detailed knowledge base of individual subject laryngeal cartilage dimensions across multiple species to assist researchers in creating subject-specific biomechanical laryngeal models. METHODS The raw data from previous laryngeal cartilage studies were grouped by species (for human, canine, and ovine) and by cartilage (arytenoid, thyroid, and cricoid) by means...
