Endoscopic lateralization of the vocal fold

Area of Science:

• Otolaryngology
• Laryngology
• Surgical Innovation

Background:

• Vocal fold paralysis in adduction leads to significant respiratory compromise.
• Current surgical interventions like lateralization or arytenoidopexy often require open approaches.
• There is a need for less invasive methods to address glottic stenosis.

Purpose of the Study:

• To describe a novel, purely endoscopic vocal fold lateralization technique.
• To evaluate the efficacy of this technique in improving respiratory function.
• To assess the preservation of laryngeal architecture.

Main Methods:

• An original vocal fold lateralization procedure performed exclusively via an endoscopic approach was developed.
• The technique aims to increase the glottic aperture.
• Patient outcomes regarding respiratory function and laryngeal structure were assessed.

Main Results:

• The endoscopic technique successfully enlarged the glottic aperture.
• Patients experienced permanent improvement in respiratory function.
• Laryngeal architecture was preserved throughout the procedure.

Conclusions:

• Endoscopic vocal fold lateralization is a viable alternative to open surgical techniques.
• This method offers a minimally invasive approach to treating vocal fold paralysis in adduction.
• The technique provides lasting respiratory benefits while maintaining laryngeal integrity.
