Clinical Characteristics of the Intracordal Cysts
;;;;;;;
;;;;;;;
ABSTRACT
Background and Objectives
: Intracordal cysts may occur secondary to voice abuse and overuse or may be secondary to a remnant of epithelium trapped within the lamina propria. They nay occur spontaneously or may be associated with poor vocal hygiene. As the cyst enlarges it can start to significantly affect the vibratory region of the vocal fold. Recently, with the advancement of the microsurgical technique and the laryngeal stroboscopy, correct diagnosis of intracordal cyst have been increased. The aims of this study is to review the important clinical characteristics of the intracordal cyst.
Materials and Method
: In the present study, 121 cases of the intracordal cyst were treated by the microsurgical technique. These lesions were diagnosed before the operation with indirect laryngoscopy, laryngeal endoscopy, laryngeal stroboscopy and confirmed with the findings observed during operations and the results of the biopsies.
Results
: The intracordal cysts were 121 cases in the 2595 patients who underwent laryngeal micorosurgery(4.7%). Ductal cyst were 88 cases and epidermoid cyst were 33 cases. The lesions are more frequent in women and anterior third of true vocal cord is more frequently involved site. With the indirect laryngoscopic examination, the ductal cysts are more frequently misdiagnosed as other diseases of the vocal cord such as vocal polyps or nodules. The degree of postoperative voice satisfaction is similar to that of vocal polyps.
Conclusion
: Intracordal cysts are very similar to the other mucosal disorders of the vocal cord and it may be misdiagnosed as vocal polyps or nodules, frequently. Therefore careful preoperative examinations for the vocal cord lesions with stroboscopy and other endoscopic instruments are important part of the correct diagnosis. An ideal treatment is enucleation of the cysts without upture of the cystic wall or injury of the lamina propria.
