Percutaneous Corticosteroid Injection for Vocal Fold Polyp

Abstract

Percutaneous corticosteroid injection can be used to manage vocal fold polyps with low invasiveness and minimal morbidity. It offers a simple and cost-effective alternative to traditional direct microlaryngoscopic procedures.

Comprehensive Outcome Researches of Intralesional Steroid Injection on Benign Vocal Fold Lesions

“…Since then, a number of published studies have demonstrated that VFSI can be applied to treat many structural vocal fold disorders, such as vocal nodules, polyp, cyst, scar, granuloma, and Reinke's edema. [11][12][13] The clinical effectiveness of VFSI was further documented in our recent study that demonstrated significantly higher lesion reduction rates after VFSI than following vocal hygiene education. 22 This study investigated the multidimensional treatment outcomes among the most common vocal fold pathologies.…”

“…39,40 For patients with vocal polyps, this study demonstrated significant improvements in most of the outcome parameters, comparable with results from a previous study. 13 Subsequent analyses revealed that patients with dysphonic symptoms lasting for more than 1 year were more likely to have higher VHI-10 scores postoperatively (Table 3, upper half). It is likely that chronic vocal polyps may present with a higher degree of fibrin deposition, inflammation, and amyloid-like material Atrophic vocal folds recovered completely after 2 months (D).…”

“…[8][9][10] A number of studies have advocated the potential role of vocal fold steroid injection (VFSI) for the treatment of benign vocal fold lesions. [11][12][13] However, few studies have investigated the treatment outcomes between different disease entities. Moreover, the prognostic factors of VFSI (eg, laryngopharyngeal reflux [LPR] and occupational vocal demand) have rarely been reported in the literature.…”

The results of steroid injection on vocal fold polyps

“…Thus, the vocal fold polyps regress because further collagen production is prevented. [7] Costicosteroids are most effective when used to treat hemorrhagic, fibrous, and fusiform polyps. [8] We found that polyp size was also an important determinant of prognosis.…”

“…[7] In addition, local drug administration is advantageous in patients who cannot tolerate general anesthesia. We delivered the corticosteroid through the cricothyroid membrane.…”
