Short-Term Evaluation of the APrevent® VOIS Implant: Outcomes at 7 Weeks Post-Implantation.

PMID 40875726WHAT IT FOUND
A new adjustable implant for vocal fold paralysis improved voice quality and closure in 32 patients at 7 weeks.
Postoperative adjustments were possible without surgery. Results are short-term and lack a control group, so long-term stability remains unknown.
Key findings
01Patients showed significant improvement in perceptual voice quality, maximum phonation time, and acoustic parameters at 7 weeks post-implantation.
02Glottal closure improved significantly, with 65.5% of patients achieving complete closure after the procedure.
03The implant allowed for non-surgical postoperative adjustment via a port, which was performed in 5 patients without complications.

What it does not show
The study had no control group, so improvements cannot be definitively attributed to the implant rather than natural recovery or other factors. Follow-up was short, lasting only 7 weeks, so long-term stability of the voice results and implant position is unknown. Different microphones and recording systems were used across the three international centers, which may affect the comparability of acoustic data. The study population was small (n=32) and excluded patients with certain comorbidities or previous laryngeal surgeries.
Declared interests
The authors declared no conflicts of interest, and the study received no external funding.
The easy way to misread this
Do not assume these results apply to permanent, long-term voice restoration. The study only followed patients for 7 weeks, and the lack of a control group means we cannot rule out that other factors contributed to the improvement.
