Objective:
Injuries to the cartilaginous larynx are rare disorders that usually undergo good spontaneous healing and rarely require surgery.
Study Design:
Case series with chart review from patients with pseudarthrosis of the cornu of the thyroid cartilage.
Setting:
ENT department of a level I trauma center.
Subjects And Methods:
We examined the medical records of seven patients treated for impaired healing of the cornu of the thyroid cartilage at a level I trauma center between 1997 and 2009.
Results:
Seven patients were treated as a result of impaired healing of injuries to the cornu of the thyroid cartilage caused by trivial trauma (e.g., car accidents). The principal symptom was odynophagia. Computed tomography was used to confirm the diagnosis. Treatment involved resecting the cornu of the thyroid cartilage. Histology showed a hypertrophic pseudarthrosis at the base of the cornu. All patients were free of symptoms 10 days after resection.
Conclusion:
Pseudarthrosis of the cornu of the thyroid cartilage is a previously undescribed condition. Pseudarthrosis of the laryngeal skeleton should be excluded in patients with odynophagia.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
