AIM OF THE STUDY: The aim of this study was to establish a reliable educational model for and a further refinement of arthroscopic surgery in the @entity1348 ( @entity1348 ). MATERIAL AND METHODS: As a first step, the lateral-medial (length) and anterior-posterior distances (width) of the mandibular head of nine @entity1707 cadavers (country breed) of about 30 ( n=3), 60 ( n=3) and 90 kg ( n=3) body weight were measured and compared with findings in 12 adult @entity1 cadavers. The best points of access for the arthroscopic and lavage channels using the triangulation technique were determined. As determined by these findings, 15 arthroscopies were performed on eight @entity1707 TMJs under general anaesthetic. A control arthroscopy was performed after 2 weeks followed by another clinical follow-up at 4 weeks before the @entity1707 were sacrificed. RESULTS: The @entity1348 of the @entity1707 between 30 and 60 kg body weight was found to be highly comparable to the @entity1 @entity1348 . The best locations for puncturing the upper joint compartment of the @entity1348 in @entity1707 were 5.0 cm and 6.1 cm anterior to the tragus on a line drawn along the lower margin of the zygoma. The only complication encountered was a @entity281 treated successfully by antibiotics and incision. CONCLUSIONS: In our opinion, a standard and easily reproducible model is necessary for further studies in arthroscopic @entity1348 -surgery. The country bred @entity1707 represents a good model for educational purposes and for studying further refinements of arthroscopic technique.
