Autogenous fat injection effectively treats glottic insufficiency from vocal atrophy or sulcus vocalis, improving voice quality and vocal fold function. While fat reabsorption can occur, repeat procedures may enhance outcomes.

Area of Science:

  • Otolaryngology
  • Plastic Surgery
  • Speech-Language Pathology

Background:

  • Autogenous fat augmentation is used for glottic insufficiency.
  • Limited data exists on its efficacy for nonparalytic glottic insufficiency, specifically vocal atrophy and sulcus vocalis.

Purpose of the Study:

  • To retrospectively compare the efficacy of fat injection in patients with vocal atrophy versus sulcus vocalis.

Main Methods:

  • Evaluated 24 patients (16 vocal atrophy, 8 sulcus vocalis) before and after fat augmentation.
  • Assessed perceptual, acoustic, phonatory, and videolaryngostroboscopic parameters.
  • Mean follow-up was 19.5 months.

Main Results:

  • Significant improvements observed in perceptual (grade, roughness, breathiness) and videolaryngostroboscopic (vocal fold edge linearity, vibration amplitude, mucosal wave) measures (p < 0.05).

Related Experiment Videos

  • Vocal atrophy showed greater improvement than sulcus vocalis.
  • Middle glottic defects responded better than anterior or posterior defects.

    • Conclusions:

    • Fat injection is an effective autogenous implant for treating vocal atrophy and sulcus vocalis.
    • Repeat procedures may be considered to address fat reabsorption.
    • Further research into optimizing fat graft survival is warranted.
