此案例研究描述了三叉神经后分支模式的解剖学变化及其对牙科和颅面手术的临床意义。该研究提出了在老年男性尸体中观察到的两种罕见的变化。在进入右侧下颌孔之前,连接耳颞神经和下牙槽神经的三个根之一的交流分支,左侧IAN和舌神经之间的三个交流分支。这种变化的存在可能使与口腔外科手术相关的麻醉复杂化。
This
case study describes anatomical variations in the branching pattern of the posterior division of the trigeminal nerve and its clinical implications for dental and craniofacial surgery. The study presents two uncommon variations observed in an elderly male cadaver. A communicating branch connecting one of three roots of the auriculotemporal nerve and inferior alveolar nerve just before entering the mandibular foramen on the right side, and three communicating branches between the IAN and lingual nerve on the left side. The presence of such variations may complicate anesthesia associated with oral surgery procedures.
