Laryngeal Fracture
摘要
Laryngeal trauma is a rare injury that accounts for <1% of all traumas but remaining undiagnosed can be a life-threatening situation. Blunt injury is more frequent than penetrating trauma and can be caused mainly by motor vehicle accidents. Other causes are sports, firearm, falls, assaults, and strangulation (Sethi et al. Laryngoscope. 129(10):2341–6, 2019). Due to the mechanism of injury, the patient commonly presents with accompanying injuries, which leave laryngeal fracture undiagnosed. The most common symptoms include hoarseness, stridor, neck pain, dysphagia, dysphonia, and hemoptysis. On examination, flattening of thyroid cartilage protuberance, neck crepitus, and reduction in breathing sounds may be present. Some patients may remain asymptomatic though (Bourdillon et al. J Voice, 2022). Laryngeal injuries are most commonly classified according to Schaefer Fuhrman’s classification from Group I to Group V. Other existing classifications are Legacy Emanuel Hospital and Health Center (LEHHC) by Verscheuren et al. and anatomical location of injury (supraglottic, glottic, and subglottic injury) (Moroco et al. Craniomaxillofac Trauma Reconstruct. 16(1):62–69, 2023).
