Unlabelled: Glottic insufficiency is incomplete or soft closure of the true vocal folds during phonation and is a common cause of dysphonia. Treatment includes voice therapy, type I thyroplasty, vocal fold injection augmentation (with materials such as autologous fat), arytenoid cartilage repositioning, or a combination of treatment modalities. The present study aimed to compare long-term outcomes of lipoinjection medialization with type I thyroplasty for patients with glottic insufficiency.
Methods: Adult voice center patients who had undergone surgical vocal fold medialization with autologous lipoinjection or with type I thyroplasty for glottic insufficiency were included in this retrospective study. The primary outcome measures were the need for further medialization surgery and improvement in the glottic gap.
Results: There were 172 subjects included in this study: 100 subjects underwent type I thyroplasty and 72 subjects underwent autologous lipoinjection medialization. Neither age nor gender differed significantly between thyroplasty and lipoinjection groups. The rate of further medialization surgery did not differ significantly between thyroplasty and lipoinjection groups, but further medialization surgery was performed longer after the initial operation in the thyroplasty group Baseline glottic gap did not differ significantly between thyroplasty and lipoinjection groups. When improvement from baseline was compared between thyroplasty and lipoinjection subjects, the improvement from baseline was similar for both groups at 6 months and at 12 months. Voice handicap index scores improved significantly after thyroplasty or after lipoinjection, and the improvement from baseline was similar in both cohorts.
Conclusion: Both autologous lipoinjection medialization and type I thyroplasty provide effective medialization for patients with glottic insufficiency. Both techniques yield similar reoperation rates, and the benefit of surgery appears to last for at least 1 year for most patients.

Objectives: Patients with unilateral vocal fold paresis and unfavorable posterior cricoarytenoid (PCA) muscle synkinesis can be challenging to treat with medialization procedures alone. Arytenoid repositioning procedures are generally considered contraindicated in mobile vocal folds. We present two cases of persistent dysphonia following type I thyroplasty for vocal fold paresis that improved after botulinum toxin-A (BTX-A) injection into the PCA muscle.

Objective: Type 1 Thyroplasty is a well-established procedure used for medializing an immobile vocal fold. Silastic and Gore-Tex are the two most common materials used to accomplish this, but comparative data on their relative efficacy are scarce. We sought to compare outcomes between Silastic and Gore-Tex implants via systematic review and meta-analysis for unilateral vocal fold immobility.

Objective: This observational study aims to evaluate the efficacy of type III thyroplasty (TP3) in achieving vocal masculinization in transgender men who have not obtained satisfactory results from testosterone therapy alone. Specifically, it aims to determine the change in the fundamental frequency (F0) of the voice before and after surgery and compare the results with previous studies.
Study Design: A retrospective observational study.
