An isolated thyroid cartilage fracture is very rare. 1-5 More interestingly, an isolated thyroid cartilage fracture from a wrestling injury, especially in a non-sports competition context, such as horseplay, has not been previously reported in the literature. Sports-related injuries to the larynx and related structures are uncommon. 6,7
A 38-year-old man presented with a complaint of throat pain after wrestling at home, in horseplay, with his 15-year-old son. He reported that when his son placed a choke hold on him, he felt a "crack" in the area of his neck, and soon afterwards felt throat pain with swallowing, along with discomfort with breathing. He also felt a sensation of "fluid building up in his throat. " There were no changes noted with his voice and the patient was speaking in full sentences. There was no wheezing or stridor. He denied shortness of breath or any other complaints. He denied pain over the posterior elements of his cervical spine. At the time of the incident, there was no loss of consciousness. Palpation of the neck and chest did not elicit any crepitance to suggest subcutaneous emphysema. The trachea was midline. There was no pain overlying the carotids bilaterally, and the patient had no bruits. The neck examination did not show any surface abnormalities to suggest trauma, such as ecchymosis or swelling. He did have slight tenderness to palpation over the thyroid cartilage.
The patient was sent for a computed tomography (CT) scan of the soft-tissue neck with intravenous (IV) contrast, and a CT scan of the cervical spine. The results showed no cervical spine fracture. However, there was a minimally displaced fracture of the left thyroid cartilage, with soft-tissue swelling that was noted, along with minimal narrowing of the subglottic trachea. There were no abnormal enhancements or fluid collections. No evidence of vocal cord abnormality or asymmetry was seen, and there was no evidence of airway compromise ( Figure).A consult with an otolaryngologist was obtained, and transfer to the tertiary care center was recommended. The patient was successfully transferred and observed for 24 hours; he was discharged home in good condition the next day.
Our patient sustained an isolated thyroid cartilage fracture. A thyroid cartilage fracture is a type of laryngeal fracture. Using an anatomic system in which such injuries are classified by location (supraglottic, glottis, or infraglottic), a thyroid cartilage fracture is classified as a supraglottic laryngeal injury. 1,2 In our case, the fracture was due to a blunt force mechanism. Most blunt force laryngeal fractures are associated with multiple trauma. 8 An isolated thyroid cartilage fracture is very rare. 1-5 More interestingly, an isolated thyroid cartilage fracture from a wrestling injury, especially in a non-sports competition context, such as horseplay, has not been previously reported in the literature.
Sports-related injuries to the larynx and related structures are uncommon. 6,7 When reported, significant force is usually involved. For example, Tasca et al 6 reported a thyroid cartilage fracture from direct blunt trauma (rugby, opponent stamped on patient ’s throat) in which the patient presented with pain with swallowing and a lowering of the pitch of his voice. Rejali et al 9 reported the case of a midair collision in a soccer match, resulting in an obvious mandibular fracture, but with an arytenoid cartilage fracture that was not initially identified. A football struck a 17-year-old boy with a resulting fracture of the superior cornu of the larynx and a puncture of the laryngeal mucosal wall in a case reported by Saab and Birkinshaw. 10 The patient presented with neck pain and dysphagia, as well as subcutaneous air. 10 A 21-year-old collegiate basketball player was struck in the neck by a teammate ’s head while jumping for a rebound. He sustained a fracture of the thyroid cartilage and a fracture of the anterior cricoid ring. 3Patients with such injuries "may appear deceptively normal when seeking medical attention. "8 Kragha 2 refers to such injuries as "rare but potentially deadly. "
Symptoms can include neck pain, voice changes, pain with swallowing, and shortness of breath. Signs can include tenderness, ecchymosis, and even subcutaneous emphysema. There may be loss of prominence of the thyroid cartilage. 3 Tracheal deviation and stridor can occur. 10,11 Computed tomography scan and laryngoscopy can be helpful in the diagnostic process; 3-dimensional (3-D) reconstructions may be needed.
Various classification systems have been proposed with related treatment strategies. Percevik et al 11 summarized a five-part clinical
