Microvascular Lesions of the Vocal Folds in the Patients with Hoarseness / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: The various types of varix which has a dilated, tortous, elongated blood vessel arising from the microcirculation of the vocal folds may cause different types of dysphonia. There have not been many specific studies on the characteristics of microvascular lesions of the vocal folds, so authors tried to evaluate the shapes, traveling pathway, and predilection site of the microvascular lesions. MATERIALS AND METHODS: A retrospective review of 119 patients with dysphonia was undertaken. All findings of videotapes were evaluated according to the shapes, the traveling pathway, the predilection sites and accompanying disorders of the microvascular lesions. RESULTS: The most common shapes of the microvascular lesions were the abrupt developed type and the multiple dilated type. The longitudinal type was the most common traveling type. The superolateral surface of the vocal folds was the predilection site of the microvascular lesions. Functional voice disorders, such as laryngeal nodule, laryngeal polyp, laryngeal edema, were more common as accompanying disorders. CONCLUSION: Authors found that there were a variety of types of microvascular lesions.
