I agree! I was only able to find a little bit of research in the time I had available and so far it appears that the thyroid cartilage followed by the the hyoid bone are the most commonly structures to be fractured due to manual strangulation, though finding evidence of such fractures on hyoid bones are still rare overall, mainly when it comes to kids and young adults, their absence does not rule out the possibility that manual strangulation occurred.
Additionally when skeletal remains are discovered it is often difficult to find or recover the corresponding hyoid bones, which are considered “free-floating” in the human body, along with them.
Furthermore, the greater horns of the hyoid bones are the most likely sections of the hyoid structure to be fractured. However, in the case of Shannan Gilbert the greater horns of the the hyoid bones were unfortunately not able to recovered with rest of her remains. Likely this may have resulted in part due to the greater cornu not fusing yet with the hyoid body, which on average occurs at age 25, according to the NIH.
In their analysis of recovered human remains, forensic anthropologists encounter structures of the throat (hyoid bone, thyroid cartilage/bone, cricoid cartilage/bone) that may present evidence of trauma. The recent published literature provides ...

Fractures of hyoid bone resulting from trauma other than strangulation are very rare; hyoid bone fracture associated with panfacial trauma are even rarer. They occur more frequently in young individuals, and in men more than in women [1]. We report ...

I agree. I wonder if perhaps that is why the Suffolk County medical examiner considered the finding a possible result of a thyglossal duct cyst, or other medical pathology, since on x-ray and CT they often appear uncomplicated, homogenous, paramedics, smooth and round and are both associated closely to the hyoid bone and are the most common cause of congenital neck masses. It’s possible that a person can live their whole lives not knowing they have one unless these cysts became infected which could lead to symptoms like dysphasia, pain or discomfort, swelling or the noticeable of development of a lump on the midline of their neck.
