ObjectiveTo explore the feasibility of type I thyroplasty using titanium clip as implant for the management of insufficient glottal closure caused by unilateral vocal fold paralysis.MethodsUsing titanium clip as implant, 15 patients were treated with type I thyroplasty to medialize the affected vocal fold and reduce glottic gap. To evaluate the improvement of glottal closure and vocal fold position, laryngoscopy and acoustic evaluation were performed, and their preand postoperative results were compared.ResultsScheduled postoperative laryngoscopic examination revealed better glottal closure with medicalization and increased tension of the paralyzed vocal fold during phonation in all patients. Their voice handicap indexes were also improved significantly. All the patients were satisfied with their symptom improvements.ConclusionWith advantages of convenience in implant insertion and good tissue compatibility, type I thyroplasty with titanium clip is effective and safe for the management of insufficient glottal closure caused by unilateral vocal fold paralysis.
