Incidence of Injury to Soft Tissue Neck Structures in Blunt and Penetrating Trauma Vascular Laryngotracheal Blunt Up to 2.7% arterial injury (13-14) 1-3% (2) Penetrating 15-25% arterial injury, 2-7% (3-4;10) 51% venous injury (4,12) Pharyngoesophageal Blunt less common than in laryngotracheal trauma (11) Penetrating 1-6% (3-4;10) Finding Management implication Bilateral RLN paralysis Protective tracheostomy Anterior commissure disruption Primary surgical repair and laryngeal stent Stable laryngeal cartilage
fracture or buckle injury ORIF and plating Comminuted, displaced (unstable) skeletal fracture(s) ORIF and laryngeal stent Cricoarytenoid dislocation, subluxation Closed reduction Epiglottis avulsion Operative repair
Maximum number of the patient attended with cut injury with larynx, laryngeal cartilage
and strap muscles of the neck and we managed such patients by resuscitation, tracheostomy and repair of the larynx in layers.
(8-16) The tumor in our patient was located outside the laryngeal cartilage
, which indicates that it was a different type of tumor--specifically, a soft-tissue giant cell tumor as described by Salm and Sissons.
Since laryngeal cartilages
originate from 4th-6th arch, so they originate from lateral plate mesoderm.
Laryngeal chondrosarcoma affects the cricoid cartilage (72% of cases) more than other laryngeal cartilages
and more than thyroid and arytenoid cartilages.
The extent of treatment depends on the tumor's stage, the presence or absence of laryngeal cartilage
involvement, and the presence or absence of metastasis.
 Major injuries include large laryngeal tears in which cartilage is exposed, severe endolaryngeal edema, fracture displacement of laryngeal cartilage
, and vocal fold fixation.
Internal factors that may affect singing include decreased lung function, ossification of the laryngeal cartilages
, and changes in the facial skeleton, while external factors encompass overall health, singing history, and vocal health.
Laryngeal cancer is the second most prevalent malignancy of upper respiratory cancers worldwide (4); which includes tumors of the larynx or any of its parts as the glottis, epiglottis, laryngeal cartilages
, laryngeal muscles, and vocal cords (5).
Fractures of the hyoid bone and laryngeal cartilages
in suicidal hanging.
Additionally, stress often causes a dry mouth, resulting in repeated clearing of the throat, cracking of the voice, or jumping of the Adam's apple (laryngeal cartilages
