The endo-extralaryngeal needle carrier

Area of Science:

• Otolaryngology
• Medical Devices
• Surgical Innovation

Background:

• Vocal cord paralysis and laryngotracheal stenosis present significant management challenges.
• Current suture techniques for these conditions can be invasive and difficult to perform endoscopically.
• Accurate suture placement is crucial for effective vocal cord lateralization and stent fixation.

Purpose of the Study:

• To introduce a new laryngeal needle holder designed for endoscopic suture insertion.
• To facilitate the lateralization of paralyzed vocal cords.
• To enable secure fixation of endoscopically placed stents or keels in laryngotracheal stenosis.

Main Methods:

• A novel laryngeal needle holder was developed for endoscopic use.
• The instrument utilizes a curved, nontraumatic cutting needle to deliver suture material.
• The technique involves inserting the needle endoscopically, exteriorizing it through the neck skin, and retrieving the suture.

Main Results:

• The devised needle holder allows for precise endoscopic suture placement.
• The method simplifies the fixation of stents and keels in airway stenosis.
• It offers an alternative to traditional, more cumbersome suture techniques.

Conclusions:

• The laryngeal needle holder provides a more efficient and less invasive approach to vocal cord and airway reconstruction.
• This innovation enhances the feasibility of endoscopic management for vocal cord paralysis and laryngotracheal stenosis.
• The technique improves upon existing methods by avoiding blind passage of sutures.
