A new fiberoptic transnasal endoscopic technique for laryngeal injection offers an easily mastered and well-tolerated alternative for vocal fold augmentation, especially for patients unsuitable for traditional methods.

Area of Science:

  • Otolaryngology
  • Laryngology
  • Minimally Invasive Surgery

Background:

  • Injection laryngoplasty is increasingly used for vocal fold augmentation.
  • Traditional percutaneous and transoral injection techniques have limitations, including technical difficulty, patient tolerance, and anatomical barriers.

Purpose of the Study:

  • To describe a novel fiberoptic transnasal endoscopic approach for laryngeal injection.
  • To evaluate the feasibility, tolerability, and effectiveness of this new technique.

Main Methods:

  • A new technique utilizing a fiberoptic transnasal endoscope with a flexible needle inserted through an endoscopic port was developed.
  • This method was applied for laryngeal injection under local anesthesia.

Main Results:

Related Experiment Videos

  • The transnasal endoscopic technique proved easily mastered and well-tolerated by patients.
  • It offers a viable alternative for patients who are not candidates for traditional injection laryngoplasty methods.

Conclusions:

  • Fiberoptic transnasal endoscopic laryngeal injection is a promising new method for vocal fold augmentation.
  • This technique expands treatment options for dysphonia due to glottic incompetence, particularly in challenging cases.
