A continuous cartilaginous formation in mesenchyme of the second pharyngeal arch in the embryo. The longer cranial or styloid segment is continuous with the otic capsule; its inferior end is angulated and is situated very close to the oropharynx. The smaller caudal segment is in contact with the body and greater horn of the hyoid cartilaginous structure [ MP:0004916 https://doi.org/10.1111/j.1469-7580.2006.00524.x ]
