INTRODUCTION: Type I thyroplasty is the treatment of choice for unilateral vocal cord palsy with no spontaneous recovery.
OBJECTIVES: To compare the use of silastic implant with titanium vocal fold medializing implant (TVFMI®) in type I thyroplasty for unilateral vocal cord palsy with respect to subjective and objective improvement in voice, endoscopic changes in vocal cords, surgical time, and cost effectiveness.
METHODOLOGY: This was a prospective study conducted on 40 patients with unilateral vocal cord paralysis who underwent type I thyroplasty with either silastic implant or TVFMI®. Pre-operative and four-week post-operative assessment and statistical comparison were performed by videolaryngoscopy, stroboscopy, perceptual assessment (GRBAS), subjective (voice handicap index) analysis of voice, and computer-assisted acoustic and electroglottographic assessment. The duration of surgery and cost of implant were also recorded.
RESULTS: Although both implants showed improvement in quality of voice following thyroplasty, TVFMI® presents slightly better results in objective voice analysis. The surgery time for TVFMI®insertion was shorter, but the costs were higher.
CONCLUSION: TVFMI® may be preferred for medialization thyroplasty as it presents better voice results and demands less surgical time; however, it is costlier than silastic implant.
