OBJECTIVES/HYPOTHESIS This study aimed to report our experience in the management of congenital laryngeal stenosis and to compare our series and results to published data in the literature. STUDY DESIGN Retrospective case series. Tertiary referral center for rare pediatric head and neck malformations. METHODS Medical charts of patients diagnosed with congenital laryngeal stenosis in our ins...

Gonadal differentiation, the onset of androgen-stimulated laryngeal growth and the genesis of a sex difference in laryngeal innervation, all temporally coincide with thyroid hormone (TH)-induced metamorphosis in Xenopus laevis. To explore the role TH plays in the ontogeny of the Xenopus androgen-sensitive vocal neuromuscular system, we examined gonadal and laryngeal development in tadpoles in w...

CE Dysfunction of the recurrent laryngeal nerves causes laryngeal paralysis in dogs and cats. Paralysis of the cricoarytenoideus dorsalis muscle results in an inability to abduct the arytenoid cartilages during inspiration.The resulting cross-sectional area of the glottis is inadequate for normal respiration.The most common clinical signs of laryngeal paralysis in dogs and cats are stridor, exe...

Herein, we demonstrate that Lrp6-mediated R-spondin 2 signaling through the canonical Wnt pathway is required for normal morphogenesis of the respiratory tract and limbs. We show that the footless insertional mutation creates a severe hypomorphic R-spondin 2 allele (Rspo2(Tg)). The predicted protein encoded by Rspo2(Tg) neither bound the cell surface nor activated the canonical Wnt signaling re...

Introduction: Laryngotracheal trauma is a rare life-threatening emergency that requires early identification and immediate intervention. Here, we present 26 patients with laryngotracheal trauma from a tertiary hospital in India. The aim was to describe the clinical presentation and management of laryngotracheal trauma patients.   Materials and Methods: This was a retrospective study of laryngot...

BACKGROUND AND PURPOSE Evaluation of the laryngeal cartilages is essential for the treatment strategy of patients with laryngeal carcinoma. Our aim was to assess the accuracy of preoperative clinical examinations and CT for preoperative evaluation. MATERIALS AND METHODS A prospective comparative study was performed at a university department on 30 patients with advanced laryngeal carcinomas. ...

Small ruminants are very important in securing food security and economically significant the rural community especially west African country. The larynx serves as both airway passage organ of vocalization, which associated with their own pathology diseases. In current study, 9 specimens larynxes from apparently healthy red sokoto goats were obtained Sokoto Modern abattoir, dissected, morpholog...

Image Acquisition Ultrasonography of the larynx can be performed using standard ultrasound equipment suitable for musculoskeletal examinations. A 7-10 megahertz linear or microconvex transducer provides good resolution and adequate penetration. Sedation is often necessary, as it facilitates patient cooperation and relaxation to allow extension of the head permitting access to the laryngeal regi...
