Iatrogenic laryngomucocele: a report of two cases

Background: Laryngocele is an abnormal cystic dilatation of saccule in direct communication with the laryngeal airway. Etiology of laryngocele is still unclear, but both congenital and acquired reasons have been implicated in its development. In this article, a combined laryngocele and an internal laryngocele which occurred following surgery, and the clinical and radiological features of the patients have been discussed. Results: There may be a relationship between laryngoceles and laryngeal surgery. Symptoms and signs of the disease may show quite a variation according to factors such as the subtype of the laryngocele. Diagnosis can be made by the typical presentation and laryngoscopic evaluation in the majority of cases. Recommended treatment of laryngocele is surgical excision via transcervical or transoral approach. Conclusion: Our cases show the possible association of laryngocele and previous laryngeal surgery. Pathophysiology may be explained by the ventricular mucosal remnant and development of scar tissue.
