abstract:The medial pterygoid plate (or medial pterygoid lamina) of the sphenoid is narrower and longer than the lateral pterygoid plate; it curves lateralward at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the Tensor veli palatini glides.
Conclusion The lateralpterygoidmuscle, styloid process, pterygoid process and itsmedial, lateral pterygoid platewereimportantanatomicalmarks for CTimagingdiagnosis.
