Introduction
The “Barbed Snore Surgery” is one of the last technical innovations in palatal surgery for Obstructive Sleep Apnea. The availability of a low-cost surgical model able to replicate tissue consistency and main anatomical structures could be fundamental for the spreading of this surgery. The aim of this study was to assess the feasibility of an ex-vivo ovine model in the surgical training of BSS.
Methods
After adequate preparation of adult lamb heads, a post-graduate student with no surgical expertise was guided by a skilled surgeon in the execution of two BSS procedures: “Barbed Roman Blinds Technique” and “Barbed Anterior Pharyngoplasty”. Anatomical limitations and similarity with the human tissue were assessed and recorded during the simulation.
Results
All the procedures were successfully completed. Despite proportional differences, the palatal tissue was assessed as similar in consistency and thickness to the human tissue. The simulation was considered satisfactory and suitable for surgical training.
Conclusion
This ex-vivo ovine surgical model could represent the right tool for BSS training thanks to readily available and inexpensive specimens. Moreover, it appears to present the realistic anatomy and tissue consistence essential for an adequate surgical simulation.
