The Goat Model for Exclusive Two Handed Endoscopic Middle Ear Surgery Training: A Novel Technique

Area of Science:

• Otolaryngology
• Surgical Education
• Comparative Anatomy

Background:

• Transcanal endoscopic ear surgery is increasingly popular.
• A need exists for accessible and affordable surgical training models.
• Existing models may not adequately replicate human middle ear anatomy for advanced techniques.

Purpose of the Study:

• To develop an ex vivo animal model for exclusive endoscopic ear surgery.
• To evaluate the suitability of the goat middle ear for two-handed endoscopic otologic procedures.
• To establish a comprehensive training program using this novel model.

Main Methods:

• An experimental study was conducted on 8 goat middle ear specimens.
• Goat middle ear anatomy was assessed for similarity to human anatomy.
• A surgical training program was developed and tested on the model.

Main Results:

• The goat middle ear anatomy closely resembles human anatomy for endoscopic ear surgery.
• The ex vivo goat model is suitable for two-handed endoscopic ear surgery with endoscope holders.
• The developed training program covers key otologic procedures.

Conclusions:

• The ex vivo goat model offers a viable and affordable training solution for endoscopic ear surgery.
• This model facilitates the acquisition of surgical skills for essential otologic procedures.
• The proposed training program can enhance the proficiency of trainee endoscopic ear surgeons.
