First evaluation of an ovine training model for sialendoscopy

Area of Science:

• Otolaryngology
• Surgical Education
• Anatomical Modeling

Background:

• Sialendoscopy is a key technique for salivary gland diseases.
• Existing training models, like pig heads, have limitations.
• There is a need for improved, realistic training models for sialendoscopy.

Purpose of the Study:

• To develop and describe an ovine model for sialendoscopy training.
• To compare ovine salivary duct anatomy with human anatomy.
• To provide a step-by-step approach for using the ovine model in training.

Main Methods:

• Ovine salivary duct and gland anatomy was assessed using MRI.
• An ex-vivo ovine model was designed through dissection by an experienced sialendoscopist.
• The model's utility was validated through consecutive dissections and a Likert-scale questionnaire.

Main Results:

• The ovine model demonstrated reliable diagnostic sialendoscopy in Stenson's and Wharton's ducts.
• Interventional sialendoscopy was simulated for sialolith removal in the Stenson's duct.
• Ovine and human anatomy showed significant similarities, offering a realistic training experience.

Conclusions:

• An ovine model for diagnostic and interventional sialendoscopy training has been successfully developed and evaluated.
• The model provides a realistic anatomical environment and tissue quality for training.
• Further studies are needed to validate the ovine model for beginner sialendoscopy training.
