Abstract
Although the occurrence of complete ossification of the second branchial bar (Reichert's cartilage) represented by the styloid process, the stylohyoid ligament and the lesser cornua of the hyoid is not rare, yet the number of well described cases is very small. The specimen of stylohyoid ossification here reported is very, remarkable in the extensiveness of its ossification and in the complete absence of mobility in any part of the osseous chain. It is not an uncommon thing to find segmental ossification of the stylohyoid chain with jointed styloid processes. The condition of the joints between the different pieces, including the lesser cornua, is very uncertain. Dwight states that in many cases it would appear that the joints once present had degenerated, and of seventeen compiled cases there is no single instance in which the hyoid is firmly attached to the chain so that no motion is possible between them.
