AIMS
To compare the feasibility and accuracy of three injection techniques for entering the superior joint space of the swine temporomandibular joint (TMJ).
METHODS
Nine swine were used for this study, in which 500 μL of colored dye was injected into both TMJs of each swine. Three injection techniques were used: the posterior injection (PI), the anterosuperior injection (ASI), and the lateral injection (LI) techniques. Each injection technique was performed on six TMJs. Swine were sacrificed immediately after injection and the swine head was dissected in order to observe the dye distribution. Injection was considered successful if no dye could be observed outside the superior joint space.
RESULTS
The PI technique was successful in all six TMJs (success rate: 100%), the LI technique in three out of six TMJs (success rate: 50%), and the ASI technique in two out of six TMJs (success rate: 33%); the differences were statistically significant (chi-square test, P < .05).
CONCLUSION
The PI technique was more accurate than the LI or ASI techniques in accessing the swine superior TMJ space.
目的
比较三种注射技术进入猪颞下颌关节（TMJ）上关节间隙的可行性和准确性。
方法
本研究使用了 9 只猪，在每只猪的两个 TMJ 中注射了 500μL 彩色染料。使用了三种注射技术：后注射（PI）、前上注射（ASI）和侧注射（LI）技术。每个注射技术在六个 TMJ 上进行。注射后立即处死猪，解剖猪头以观察染料分布。如果在关节上间隙外没有观察到染料，则认为注射成功。
结果
PI 技术在所有六个 TMJ 中均成功（成功率：100%），LI 技术在六个 TMJ 中的三个中成功（成功率：50%），ASI 技术在六个 TMJ 中的两个中成功（成功率：33%）；差异具有统计学意义（卡方检验，P<.05）。
结论
PI 技术在进入猪上 TMJ 空间方面比 LI 或 ASI 技术更准确。
