A low-cost transcervical laryngeal injection trainer

Area of Science:

• Medical Education
• Otolaryngology
• Surgical Simulation

Background:

• Transcervical laryngeal injection is a key skill for otolaryngologists.
• Training often relies on direct patient procedures, posing risks.
• A need exists for safe, accessible simulation models.

Purpose of the Study:

• To develop and validate a low-cost, easily constructed model for transcervical laryngeal injection training.
• To assess the simulator's effectiveness and user acceptance among resident learners.

Main Methods:

• A novel transcervical laryngeal injection simulator was constructed.
• Fourteen otolaryngology residents utilized the model for practice.
• Survey feedback was collected from all participating residents.

Main Results:

• 93% found the simulator easy to use; 79% deemed it effective for learning the technique.
• 78% reported improved confidence; 72% believed it applicable to patient care.
• 100% would recommend the simulator to peers.

Conclusions:

• A low-cost simulator provides a safe, effective training environment for transcervical laryngeal injection.
• Resident feedback was overwhelmingly positive, supporting its use in otolaryngology education.
• This model facilitates pre-clinical skill acquisition, enhancing patient safety.
