Abstract

|
|
Background and Objectives: is a gell-formed material of calcium hydroxylapatite (CaHA) and carboxymethylcellulose (CMC) used for vocal fold injections. The authors aimed to study injection laryngoplasty with , and determine the efficacy of for unilateral vocal cord palsy using objective and subjective measures.
Materials and Method: Nine patients with unilateral vocal cord palsy received injection laryngoplasty with under general anesthesia from Jul. 2007 to Jan. 2008. was injected with 25gauze long needle perorally or percutaneously. The Acoustic, aerodynamic, stroboscopic analysis and pre-injection/post-injection perceptual assessment were evaluated in all patients.
Results: Postoperative jitter and shimmer scores tended to diminish compared to preoperative scores, and maximum phonation time increased with statistical significantly. Stroboscopic findings demonstrated improvement postoperatively. The degree of hoarseness, which is a part of perceptual assessment, decreased after the procedure.
Conclusion: may be an altemative material for injection laryngoplasty. We suggest long-term follow up with more cases.
