The infant larynx differs from that of the adult in more ways than size alone . Its position in the neck is more cephalad than in the adult. The thyroid notch positioned high, posterior to the hyoid bone, the bone obscuring the thyroid notch as a landmark for tracheotomy. The epiglottis has an omega shape and may be somewhat tubular . The cuneiform cartilages, arytenoids, and posterior supraglo...

The purpose of the current study was to explore whether the laryngeal dose can be reduced by using 2 intensity-modulated radiation therapy (IMRT) techniques: whole-neck field IMRT technique (WF-IMRT) vs. junctioned IMRT (J-IMRT). The effect on planning target volumes (PTVs) coverage and laryngeal sparing was evaluated. WF-IMRT technique consisted of a single IMRT plan, including the primary tum...

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...

BACKGROUND Transoral laser microsurgery (TLM) is used to treat early and select cases of moderately advanced glottic cancer, with results equivalent to those of conventional conservative surgery and radiotherapy (RT). As surgeons and researchers become more experienced and familiar with TLM, they can focus on mechanisms to earlier detect local recurrence, to more effectively preserve laryngeal ...

BACKGROUND AND PURPOSE The posterior cricoarytenoid (PCA) muscle is one of the intrinsic muscles of the larynx innervated by the recurrent laryngeal nerve. As such, recurrent laryngeal nerve palsy should not only result in paralysis of the true vocal cord or thyroarytenoid muscle but also in a similar change in the PCA muscle. The ability of CT and MR imaging to depict denervation atrophy in th...

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...

Purpose: Analysis of ossification, bone marrow formation, perichondrium thickness, muscle fibers, collagen fibers and elastic fibers quantities of cricoid and arytenoid cartilages. Design: Correlation morphologic study. Methods: Twenty-four cricoarytenoid joints were obtained from Caucasian male fresh cadavers divided into three groups with eight specimens in each: group I – adolescents, from 1...

Introduction: The aim of the present study was to compare the videolaryngostroboscopic findings between patients with rheumatoid arthritis and vocally healthy controls.   Materials and Methods: This case-control descriptive study was performed on 113 people, including 50 patients with rheumatoid arthritis and 63 controls. The participants were subjected to videolaryngost...

127 Restoration of vocal function with laryngeal framework surgery (laryngoplastic phonosurgery) was introduced at the beginning of the 20th century. Today, these procedures have emerged as the dominant surgical management approach for the treatment of the aerodynamic incompetence and acoustic deterioration associated with vocal fold paralysis/paresis. Other indications include cancer defects, ...
