Preliminary Experience with 3-Dimensional Exoscope-Assisted Laryngoplasty

Area of Science:

• Otolaryngology
• Surgical Technology
• Vocal Fold Surgery

Background:

• Laryngoplasty involves vocal fold manipulation, often limited by poor visibility and technical demands.
• Traditional microsurgery for vocal fold issues requires specialized anatomical knowledge and a high skill level.
• A novel 3D exoscope offers a stereoscopic view, potentially overcoming limitations of current laryngoplasty techniques.

Purpose of the Study:

• To evaluate the feasibility of using a 3D exoscope for laryngoplasty.
• To compare the 3D exoscope technique with traditional macrosurgery for vocal fold procedures.
• To assess the potential of the 3D exoscope to replace existing laryngoplasty methods.

Main Methods:

• A retrospective case series included 28 patients undergoing laryngoplasty.
• Patients were divided into two groups: 3D exoscope (n=12) and macrosurgery (n=16).
• Surgical time, vocal function, complications, and staff feedback on educational utility were compared.

Main Results:

• No intraoperative or postoperative complications were observed in either group.
• Surgical duration and vocal function outcomes were similar between the 3D exoscope and macrosurgery groups.
• Medical staff found the 3D exoscope valuable for surgical education and information sharing.

Conclusions:

• The exclusive use of a 3D exoscope for open laryngoplasty is feasible.
• This preliminary study suggests the 3D exoscope is a viable alternative for vocal fold surgery.
• The 3D exoscope demonstrates potential as an educational tool in laryngoplasty procedures.
