Outcomes Tracking in Unilateral Vocal Fold Paralysis (UVFP) and Atrophy After Medialization Laryngeal Surgery

The goal of this observational study is to learn about the long-term outcomes of Laryngeal Framework Surgery (LFS) in patients with Unilateral Vocal Fold Paralysis (UVFP) or Vocal Fold Atrophy (VFA). The main questions it aims to answer are: * Whether LFS technique (implant material, addition of arytenoid adduction) is associated with differences in outcomes such as complication rate, duration of surgery, hospital stay length, and quality of voice post-surgery. * Whether UVFP or VFA diagnosis is associated with differences in outcomes such as complication rate, duration of surgery, hospital stay length, and quality of voice post-surgery. Participants who are determined by their clinician to need LFS for their UVFP or VFA will undergo the procedure, attend follow-up appointments, and complete surveys about their voice and swallowing ability as they would as part of their regular medical care.
