Case report
A 19-year-old, African American woman with a medical history significant for asthma and mitral valve prolapse presented to the emergency department as an unrestrained passenger in a single vehicle, head-on motor vehicle collision. Injuries included blunt neck trauma presumed to be from air bag deployment. Symptoms included a hoarse voice and 10/10 tenderness in the anterior laryngeal region. The patient denied chest pain and shortness of breath. Physical examination was notable for a 4-cm
Discussion
Blunt trauma to the larynx is an uncommon, often fatal injury. Prehospital mortality may approach 80% in blunt trauma involving the trachea [1]. Injuries to the trachea are more commonly seen in the lower trachea, and the mortality from these injuries has decreased dramatically from 36% before 1950 to 9% since 1970 [2]. Injuries to the larynx and cervical trachea are commonly associated with maxillofacial and cervical spine injuries [3]. Collateral injuries were not seen in this patient,

Unexpected blunt neck trauma resulting in laryngeal fracture, the case of the dangerous wooden box: A case report
2021, Trauma Case ReportsCitation Excerpt :These injuries can be missed by clinicians secondary to their low incidence and physician familiarity with the diagnosis [2,3]. The mortality associated with laryngeal fractures has been reported as high as 80% in the pre-hospitalization setting [4] to an overall reported mortality rate of 17.9% [5]. Once a secure airway is established and the laryngeal injury is correctly diagnosed the mortality rate does decrease to less than 5% [6].
Laryngeal injury in closed cervical traumatism

2014, European Journal of RadiologyCitation Excerpt :Some authors advocate open laryngeal surgery within the first 24 h while others recommend surgical exploration to be performed 3–5 days later allowing edema to resolve. According to the literature, early surgery decreases voice and airway complications by up to 40% [4–6,11,14,59]. Trauma of the anterior neck may result in various injuries of the laryngeal soft tissues, cartilages and surrounding structures.
Anesthetic Considerations for Transoral Robotic Surgery
2010, Anesthesiology ClinicsCitation Excerpt :In our practice for panendoscopy, we use a technique in which the initial laryngoscopy is performed by the surgeon using a Lindholm or anterior commissure laryngoscope (Karl Storz, Germany) with high-frequency jet ventilation. When a question arises on the ability to intubate a patient at the time of TORS, the surgeon is available with a suspension laryngoscope, and intubation is performed with an endotracheal tube styletted with a 0° endoscope.16 Other useful adjuncts include trans-laryngeal mask airway (LMA) intubation with the Aintree intubation catheter (Cook Medical, Bloomington, IN, USA)17 and the GlideScope (Verathon, Bothell, WA, USA),18 as illustrated in Fig. 5.
