Otolaryngologic clinics of North America

The otolaryngologist who is called upon to evaluate respiratory distress in the newborn should be familiar with the various congenital lesions of the larynx. A presumptive diagnosis can usually be made on the basis of the clinical history and physical findings. However, the mainstay of diagnosis is endoscopic examination of the larynx.

Diagnosis and therapy for acute laryngeal and tracheal trauma.
A laryngeal fracture should be suspected when there is hemoptysis and subcutaneous emphysema following blunt injury to the neck. Computed tomography of the neck should be used to define the extent of the injury. Cervical vertebral fractures and dislocations, perforation of the pharynx and esophagus, and vascular injuries must be excluded. ⋯ The repair of the fractured larynx requires prompt repair of lacerations of the mucous membrane, reduction of cartilaginous fractures, and internal splinting for six weeks. Anastomosis of the transected trachea is carried out prior to repair of the recurrent laryngeal nerve injury. Although suturing of the transected nerve is controversial, there is general agreement that implantation of the avulsed recurrent laryngeal nerve in the posterior cricoarytenoid muscle is appropriate.
