ABSTRACT |
Background and Objectives: $VoCoM^{(R)}$ is a set composed of prefabricated hydroxylapatite implants and shims of various sizes that are designed for the type I thyroplasty, Authors aimed to evaluate the efficacy of $VoCoM^{(R)}$ System in type I thyroplasty. Materials and Method: Twenty three patients with unilateral vocal cord palsy were included in the study, who received type I thyroplasty with $VoCoM^{(R)}$ between May 2000 and May 2007 in St. Mary's Hospital, The Catholic University of Korea, Seoul, Korea, Acoustic, aerodynamic and stroboscopic analyses were performed pre-and post-operatively, Subjective voice improvement was analysed by Voice handicap index, Results : Preoperative jitter was $4.68{pm}2.46%$ and improved to $3.19{pm}1.94%$(P<0,05), Preoperative NHR was $0.26{pm}0.1$ and improved to $0.18{pm}0,07$(P<0.05), Preoperative MPT was $6.16{pm}4.9$secs improved to $9.55{pm}4.67$secs(p<0.05), The postoperative stroboscopy revealed an effective medialization of vocal fold of all patients, Conclusion: Type I thyroplasty using $VoCoM^{(R)}$ is a efficient, safe and convenient way of vocal fold medialization at the expense of its high cost and difficulty in removal. |
